Many are familiar, because it can be easily found on the UAZ Patriot, for example. The motor does not scold only the lazy. Low power with a volume of 2.7 liters, high fuel consumption, a complex timing system with a chain drive and 16 valve mechanism. They tried to modernize the 409 motor more than once. Recently, another version of the 409 ZMZ motor has appeared, this is the ZMZ PRO. Essentially the same in-line 4-cylinder 16-valve gasoline-powered engine. But according to its creators, this is a real breakthrough. After all, the power was brought up to 149 hp. with the possibility of increasing up to 160 horses! Torque has increased to 235 Nm.

In addition, ZMZ PRO will be offered from the factory in two versions at once - gasoline and gasoline / gas. Liquefied gas (propane-butane) available everywhere will be used as a gas motor fuel. It was possible to increase the power due to a lightweight piston group, an increase in the compression ratio of the valve timing reconfigurations.

Characteristics of the ZMZ PRO engine (ZMZ 409-051)

Displacement - 2693 cm3 Number of cylinders - 4 Number of valves - 16 Bore - 95.5 mm Stroke - 94 mm HP - 149.6 at 5000 rpm Power kW - 110 at 5000 rpm Torque - 235 Nm at 2650 rpm Compression ratio - 9.8 Timing drive - chain Fuel type - gasoline AI 92

Characteristics of the ZMZ PRO engine (ZMZ 409-052)

Displacement - 2693 cm3 Number of cylinders - 4 Number of valves - 16 Bore - 95.5 mm Stroke - 94 mm HP - 143 at 5000 rpm Power kW - 105 at 5000 rpm Torque - 227 Nm at 2650 rpm Compression ratio - 9.8 Timing drive - chain Fuel type - gasoline AI 92 / Gas (propane-butane)

In September 2017, in Moscow, at the Crocus Expo exhibition complex, the International Exhibition of Commercial Vehicles Comtrans 2017 was held. At this exhibition, UAZ showed a new UAZ-Profi commercial vehicle in which a new ZMZ-PRO engine was installed. The new engine is naturally a good (hopefully) reworked old ZMZ-409.

With this degree of compression, 95th gasoline is supposed to be poured into it. Which is not very good for commercial vehicles. But there was a modification Gas-Gasoline. Such an engine bears the abbreviation ZMZ-409052. The equipment is Italian, the brains are accordingly tuned to the dual-fuel mode.

The single-row chain, which was torn on the Patriots, was finally changed to a double-row one. (who remembers, the two-row chain was at EURO-3, they returned, so to speak) The tension shoes were gone and sprockets appeared again. INA hydraulic tensioners, ELSE will break this chain too :)

The rollers are also imported. The pan gasket is now metal. This is to prevent oil leakage.

New valves. The valve timing has changed. The gearbox was "adapted" to the new engine. But what exactly has changed - is still unknown. Installed a warranty on the engine for 2 years or 200 thousand km. Wait and see!

Manufacturer Features and Expectations

ZMZ expects success from the ZMZ Pro engine. This power unit should be the best in the entire line. As it became known, GAZ plans to resume production of the Volga and wants to install the new 409th engine on the updated passenger version. It should be understood that these are just unconfirmed rumors that may not come true. The new ZMZ 409 Pro will be installed on cargo versions of vehicles of the Ulyanovsk Automobile Plant for the time being. If the engine becomes successful, then this could significantly undermine the sales of the Gazel NEXT, because it was not for nothing that the engine began to be called the “Gazelle killer”. But let's wait and see what happens. The mass production and operation of the ZMZ 409 Pro engine will show how successful the manufacturer's expectations and promises will be. So far, one can only assume that the designers took into account the bitter experience of their elder brother and really modernized the motor, which brought it closer to international quality and standards. The preliminary rating of the power unit is 7 out of 10 points.

Self-diagnosis and typical malfunctions of gasoline engines

Almost all new cars today are equipped with on-board computers that control the operation of the engine, as well as generate and store error and fault codes. However, the computer generates fault codes only for the electronic part of the control system, ignition system and other systems in which electronics are involved. And mechanical malfunctions of the engine, such as wear, breakage of parts, etc., are diagnosed only by visual inspection, listening to the operation of the engine, and other external signs.

drives, etc. Now you can start the engine and after it warms up and enters the operating mode, look at the exhaust gases, their color can tell a lot about the state of the power unit. White exhaust. White color indicates the presence of water vapor in the exhaust gases. White exhaust is quite normal for the first minutes of starting the engine, especially in cold weather (since the condensate that has settled inside the exhaust pipe and muffler evaporates), but if such exhaust remains even after the engine warms up, then this indicates that coolant has entered the cylinders. The white color of the exhaust is given by the steam that occurs due to the presence of water in the coolant. Typically, this situation occurs when cracks appear in the cylinder block or when the gasket between the block and the cylinder head burns out. However, sometimes white smoke from the exhaust pipe has a bluish tint, which also occurs when oil enters the cylinders. Therefore, it is necessary to ensure that white exhaust is produced

The engine is one of the most important and complex units in a car. Modern motors are very reliable and efficient, however, under the influence of mechanical and thermal loads, as well as for other reasons, various malfunctions can occur. About breakdowns of gasoline and diesel engines, their causes and solutions are described in this article.

The main manufacturers of passenger engines in Russia

It is generally accepted that in Russia there is currently little production of equipment, which, moreover, is of extremely low quality, lagging behind the quality of foreign models. However, everything is far from being the case: now our country has developed mechanical engineering, including engine building for various industries: automotive, tractor, shipbuilding, aircraft building, production of generator equipment, etc. And there are now at least three dozen factories producing motors in Russia.

SOHC and DOHC engines: two against one

When choosing a new car, the buyer may be faced with an unusual task at first glance: to take a car with a SOHC or DOHC engine? About what these abbreviations mean, how these engines differ, and what advantages and disadvantages they have - read in this article.

about half a century ago, and today there are several varieties of engines of each design. SOHC Engines Powerplants with a single overhead camshaft experienced the peak of their popularity back in the 60s and 70s of the last century, but they are still being installed in economy class cars today. There are three schemes according to which the SOHC timing belt is implemented, they differ in the type of drive and valve arrangement: - Valve drive using rocker arms that are pushed by the camshaft cams. The valves are located in a V-shape on both sides of the shaft; - Valve drive by levers, which, in turn, are pushed by camshaft cams. The valves are arranged in a row; - Valve drive with pushrods, which are located directly under the camshaft. Valves are arranged in a row. The scheme with rocker arms is simple. The rocker arms are mounted on an axle on which they can swing freely. On the one hand, they rest against the valve stems, on the other

REGULAR application of timing chains in ZMZ engines of the 409 family according to EURO standards:

1. Euro 2 -double row bush chain (DVC 06-E2) with 5.5 mm bushings. Double-row chains of the "heavy" series, connecting plates have a thickness of 1.0-1.2 mm and ground ends facing the chain and tensioners. Installed until mid-2008:

406.1006040-10 (90 links)	406.1006040 (70 links)

1. Euro-3 (engines 409.04) -double-row sleeve chain (DVTs 06-V2) with bushings 6.35 mm. Chains of the "light" series, connecting plates have a thickness of 0.7-0.8 mm. Installed from mid-2008 to mid-2010:

406.1006040-30 (92 links)	514.1006040-20 (72 links)

This is the leader in reliability, of all REGULARLY installed chains.

1. Euro-3 (ZMZ-409.04 engines from mid-2010 to 2012; 4091 engines) - single row bush chain (VTS 06-V1) with 6.35mm bushings (Mid 2010 to 2012):

406.1006040-40 (92 links)	514.1006040-40 (72 links)

Sleeve chains of the drive of the mechanism of gas distribution of the engine are used at relatively low operating speeds in conditions where pollution, dust, humidity and other environmental influences cannot be avoided. Such chains are distinguished by a larger hinge area compared to roller chains, which is achieved due to the larger diameter of the roller and bushing while maintaining the main dimensions of the chain. Bush drive chains are produced according to GOST 13568-97, ISO 1395 standards.

1. E4 - toothed-lamellar chain (ZPC, aka "Morse Chain"):

40904.1006040-11 (108 links)	40904.1006040-01 (84 links)

Break test results:

DVC... double-row sleeve chain - 1600-1800 kgf,

VC..... sleeve chain - more than 2300 kgf.

VRC... .. bush-roller chain - a little less than 3000 kgf

ZPC... toothed-lamellar chain - more than 3000 kgf.

Features of the toothed-lamellar chain of the ZPC:

ZPC is considered to be a high-speed chain with the smallest kinetic mass of all chains, ZPC less impedes the rapid increase in engine speed, is able to move at a higher speed and withstand greater loads than bush chains. But this chain is designed for uniform loads without jerks, it is necessary that high-quality correctly selected hydraulic tensioners are included with the toothed-lamellar chains. One of the reasons for the rapid exit ZPC failure is a deterioration in the operation of the hydraulic tensioner due to its clogging, which quickly affects the condition ZPC.

ZPC has a weak damping effect due to the rigid nature of the contact with the sprockets, close to the gear train. When entering the sprocket, the pliers of the chain links grab the teeth of the sprocket and release the teeth when leaving the sprocket. With this method of engagement of sprockets with ZPC it is especially important to monitor the uneven stretching of the chain. When the chain tension is loosened ZPC The sprocket "moves out" along the teeth, up to the disengagement of ALL the teeth from the sprocket, and if they jump, then not by one or two teeth, but up to a whole revolution of the crankshaft. Often skipping ZPC occurs on a run up to 20,000 km.

On the teeth of the regular sprockets of the ZMZ-40905 Euro-4 engines, there are traces of pincer grips of the links ZPC. Perhaps the sprocket gears should have a greater or the same hardness as ZPC, which has a chain link hardness of about 54 HPC.

Bush-roller chain (DVRTs and VRTs)

The best performance in terms of resource and friction reduction in the gas distribution drive mechanism was shown roller chains , manufactured according to the ISO standard: VRTs (single row) And DVRTS (two-row). In contrast to the sleeve chains used on engines of the ZMZ-409 family DVC 06-E2 And DVC 06-V2, due to its design, when the chain enters 3 teeth of the sprocket, and when the chain comes off the last 3 teeth, they do not come into contact with their surface, but run in rollers installed on the chain bushings, which rest on the cavity of the sprocket teeth. This reduces friction in chain-sprocket pairs, there is no heating of the chain, wear of the sprocket tooth cavities and surfaces of chain tensioners.

The use of single-row bush-roller chains VRC, significantly reduce the weight of rotating and moving parts and further increase the efficiency of the engine.

In the timing of UAZ vehicles, especially in conditions of harsh vehicle operation, the use of VC And VRC preferable - their resource is less dependent on jerks, tk. sleeve chains dampen alternating loads and resonant jerks much better. The use of bush chains increases the reliability of the entire engine and, as a result, the vehicle.

These circuits are not regular, at the factory not installed. One of the most reliable kits on the market, for example, a Progress-motor kit with FERC and shoes:

Roller chains of the engine timing mechanism drive designed for power mechanical transmission of various machines and mechanisms. These chains are used at speeds up to 30 m/s, at temperatures up to 300°C. Drive roller chains are produced according to GOST 13568-97, ISO 606, ANSI B29.1M standards. Each repeating chain segment includes 2 external and 2 internal links, consisting of metal plates, rollers, bushings and rollers.

409 engine was produced by the Zavolzhsky Motor Plant by order of the Ulyanovsk Automobile Plant. The motor has increased technical characteristics.

Specifications

The 16-valve ZMZ 409 engine was designed specifically for installation on cars of the Ulyanovsk Automobile Plant. This power unit is somewhere between 405 and 410 motors, or rather a fusion of their best components and characteristics.

In the case, as with the 405, the following improvements were installed on the 409: an upgraded valve cover, a gas distribution mechanism, an installed two-layer metal cylinder head gasket. True, the difference was that the volume of the power unit was increased to 2.7 liters, which entailed increased consumption.

Since the internal combustion engine is produced for Ulyanovsk cars, it is often confused with UMP, and is called the UAZ engine.

Power unit ZMZ 409 specifications:

6. ZMZ 4092.10 - non-serial motor. Power 160 hp Used on the Volga.

Service

Maintenance of the engine is expected after the expiration of 15,000 km of run. On automotive forums, the question is often asked - how much oil can the engine hold? So, the motor holds 7 liters of engine oil, but only 6 liters are required when replacing.

The maintenance card is no different from the 409th, and looks something like this:

1. 1000-2500 km or TO-0: oil and oil filter change.
2. 8000-10000 km - TO-1: oil change, oil and air filter, spark plugs, high-voltage wires, fuel fuel.
3. 25,000 km - TO-2: oil change, oil filter.
4. 40,000 km - TO-3: oil change, oil and air filter, spark plugs, high-voltage wires, valve adjustment.
5. 55,000 km - TO-4: oil change, oil filter, fuel filter, replacement of the timing chain and alternator belt.
6. 70,000 km - TO-5 and subsequent: oil and oil filter change. Every 20,000 km it changes - the fuel and air filters, the valves are adjusted. Every 50,000 km - timing chain replacement.

Faults and repairs

When the technical characteristics and the device are considered, it is worth moving on to consider the main problems, as well as how the ZMZ 409 engine is repaired.

Important! Before you repair ZMZ 409 with your own hands, you should study the repair manual for the power unit, but if the motorist is confident in his abilities, then we proceed directly to action.

The most common problem is tripping and floating speed. You can fix this malfunction yourself without leaving the garage. So, consider the causes and methods of troubleshooting.

Bad fuel and power system

If low-quality fuel was poured into the fuel tank, this can clog the power system, which will lead to floating speed and tripling. To fix the problem, you will need to clean the entire system, as well as clean the nozzles. After the procedure is completed, it is worth checking the performance of the power unit.

Spark plugs and high voltage wires

Often, candles and wires can become a problem. Repair ZMZ 409, in this case, is quite simple. Old parts are unscrewed, inspected, and, if necessary, changed. It is worth remembering that before installing new spark plugs, it is worth setting the gap between the electrodes. If this is not done, then the combustion of the fuel will not be uniform, which leads to the effect - the valves burn.

Sensors and ECU

Conclusion

Motorists prefer to do the repair and tuning of the ZMZ 409 engine on their own. The motor has a fairly high technical characteristics, and the design simplicity allows for revision almost in the garage.

The powerful gasoline engine of the ZMZ-409 brand, which is equipped with cars of such popular brands as GAZelle, Sobol and UAZ Patriot, has gained wide popularity. UAZ-3163 first left the assembly line in 2005, and it was then that for the first time it was equipped with an engine of the Zavolzhsky plant of the ZMZ-409 brand. Let's consider what the ZMZ-409 brand ICE is, which UAZ Patriot SUVs are equipped with, what is the power of such a unit, as well as its fuel consumption.

The internal combustion engine of the ZMZ-409 brand is presented in the form of a four-cylinder four-stroke unit with an overhead valve arrangement and forced liquid cooling. This engine in the design has a system of distributed injection of the fuel mixture and a microprocessor type of ignition.

Gray cast iron is the main material from which the ZMZ-409 engine block is cast. In the design of an engine that complies with Euro-3 and Euro-4 standards, there are special triangular-shaped channels with rounded corners between the cylinders, through which the coolant is circulated. In the cylinder block of the ZMZ-409 engine, which complies with Euro-2 standards, the holes are made in the form of transverse slots 2 mm wide. The cylinders are molded into the body of the block, so they have a non-removable design. The cylinder head is made of aluminum alloys. Each cylinder has 4 valves, two of which are intake and two exhaust. The design of the motor already has all the main types of fasteners, with the help of which attachments are mounted.

The engine in its design has hydraulic pushers that allow you to adjust the gaps of the cams in automatic mode. In the lower part of the block there are combustion chambers in which the combustion of the fuel mixture takes place. The camshafts are made from cast iron, while the pistons are cast from an aluminum alloy. Pistons are the working element that drives the crankshaft.

Each piston is equipped with special recesses that are designed to prevent the product from hitting the valve discs. The crankshaft is made of high-strength cast iron, which ensures its reliable operation. The crankshaft has five supports, and the presence of counterweights makes it possible to unload the supports. The direction of rotation of the crankshaft is right, and the functioning of the cylinders is carried out according to the scheme 1-3-4-2. The technical characteristics of the piston provide for the presence of two compression and one oil scraper ring on it.

The working volume of the internal combustion engine of the UAZ Patriot SUV is 2.6 liters. The total weight of the ZMZ-409 motor is 190 kg. The lubrication network is presented as a forced and combined system. The power of the gasoline engine of the UAZ-3163 SUV is 128 horsepower. Such power allows the SUV to overcome various kinds of obstacles and feel worthy on the track. Equipping the SUV UAZ-3163 with an internal combustion engine of the ZMZ-409 brand made it possible to obtain high cross-country performance in aggressive off-road conditions. The disadvantage of such an engine can be called a rather big fuel consumption, which is about 13 liters per 100 km with mixed traffic.

This consumption is due to the large volume of the motor, which is necessary for the development of torque. But high power and low consumption are two incompatible things that are characteristic of any gasoline units.

Lubrication system

The lubrication system on the Patriot is a combination lubrication system that functions by spraying oil between friction parts when pressure is applied to it. The design of the lubrication system of the UAZ Patriot SUV includes:

• crankcase;
• pump;
• nozzles;
• valve;
• oil channels;
• oil filter.

An electronic oil pressure sensor in the system prevents such an effect as crankshaft jamming when the lubricant pressure decreases. The lubrication system of the ZMZ-409 engine is an important and integral part of it, without which the operation of this unit would be impossible.

Fuel system

Fuel is supplied to the cylinders by means of an injector. The injector is controlled by an ECU, which has a large number of different sensors. The sensors send signals in the form of electrical impulses to the control unit, as a result of which the latter reads and analyzes the situation.

If you plan a mixed type of operation of an SUV, then to save fuel, you can install gas-cylinder equipment, which will save almost half. The Euro-4 gasoline engine of the UAZ-3163 SUV is perfect for installing 4th generation HBO.

Fuel supply is carried out directly from the tank, in which the fuel pump located under the passenger seat takes part. The presence of a fuel filter in the fuel supply system avoids the ingress of various particles into the cylinders.

Service

The technical characteristics of the ZMZ engine on the UAZ-3163 allow you to operate the car both off-road and on the highway. Periodically, the motor requires maintenance, which will extend its service life.

The characteristics of the ZMZ-409 engine are due to the fact that with regular maintenance, stable operation can be achieved. Euro-4 environmental standards, which are typical for a gasoline engine installed on an UAZ Patriot SUV, make it possible to pollute the atmosphere in minimal volumes. So that the engine does not fail on the way, it is necessary to refuel high-quality fuel with an octane rating of at least 92, as well as control the timely replacement of engine oil.

The technical characteristics of the ZMZ-409 engine on the UAZ Patriot SUV indicate that this engine is really worth the money. If you compare the technical characteristics and operating parameters of the Patriot and any foreign car, you will notice that the domestic unit is practically not inferior, especially if you take into account the significant difference in cost.

UAZ Patriot with ZMZ-409 engines are produced to this day, but in addition, these SUVs are being modernized every year, and are increasingly approaching foreign standards. You can buy a UAZ-3163 with a gasoline engine today for 800,000 rubles, while a foreign SUV will cost 1.5 million rubles.

The technical characteristics of the ZMZ-409 motor indicate not only its advantages, but also its disadvantages. Therefore, high fuel consumption, a drop in power at speeds above 90 km / h and a lack of strength at low speeds are all characteristic of the Patriot. Therefore, when choosing an SUV, it is important to find out all the technical characteristics of the motor so as not to regret the choice after making a purchase.

You can check your CBM and reduce it if needed!
