The new one could probably change attitudes towards gasoline engines forever internal combustion. But what we know for sure is that it is already capable of changing the compression ratio from 8:1 to 14:1, thereby approaching the fuel efficiency indicators of diesel engines.

Officially, the luxury division of Nissan will present its development, turbocharged engine With variable degree compression (VC-T), next month . It took more than two decades to perfect the technology, resulting in a high-performance engine model that the developers claim has managed to maintain fuel efficiency (diesel) and power (gasoline).

Here's how it works, let's briefly consider the use of technology using an example circuit:

Meaning new technology is that by changing the stroke length, the engine can infinitely vary the compression ratio in the range from 8:1 to 14:1. When electronic controller motor control finds what you require more power, the drive lever acts on the control shaft by changing the position of the multi-link system of levers rotating around the main bearing of the connecting rod, lowering the piston in the cylinder. This reduces the compression ratio, allowing the turbocharger to pressurize safely without the risk of skipping cycles or detonation. But when driving top gear at high speeds, the system will work in reverse, allowing for as much compression as possible to improve fuel economy. The new engine's electronic valve timing and direct fuel injection system additionally allow instantaneous switching between conventional and Atkinson cycles.

SAAB's idea was to create an engine consisting of two blocks that could press the cylinder head towards the block with hydraulic drive to increase the compression ratio. The ability to change the working volume allowed the engine to run on three types of fuel: gasoline, diesel fuel or on alcohol.

The SVC project was shelved after the acquisition by GM, making Infiniti's VC-T technology the first pre-production model of its kind that appears to actually go into production.

At least in order to understand the level of manufacture of this premium business SUV. In it you will find a lot of interesting…

First diesel Infiniti FX30d - specifications, prices

This year, for the first time in the Russian market, sales of the Infiniti model with a diesel engine, the Infiniti FX30d, will start, the characteristics of which deserve the most careful consideration. At least in order to understand the level of manufacture of this premium business SUV. In it you will find a lot of interesting…

As a reminder, the FX model has a strong position in the highly competitive premium SUV segment, and the introduction of a diesel version will strengthen Infiniti's offering in this segment. The high torque of the Infiniti FX30d diesel engine opens up new levels of driving pleasure. Infiniti FX30d diesel has it all best qualities The premium car is close to the performance and comfort of a sports car with a petrol engine, while being fuel efficient and with a long range.

Crossover Infiniti FX 2012 model year received a number of updates. The Infiniti FX's front end design has become more aggressive with changes to the grille, headlights and front bumper. The car is equipped with 20-inch rims new design. The interior has also undergone changes: the arrows on the updated dashboard are now made in white, trip computer received new screen and completely Russified.

Characteristics of the Infiniti FX30d by engine

Diesel modification luxury crossover The Infiniti FX is equipped with a 3.0-liter V6 engine (238 hp) and 550 Nm of torque, which combines compliance with strict environmental standards and impressive power and dynamism. Max Speed is 212 km / h, acceleration 0-100 km / h in 8.3 seconds. Fuel consumption in combined cycle- 9.0 l / 100 km, in the extra-urban cycle - 7.8 l / 100 km, and the extra-urban cruising range is 1100 km.

The perfect diesel engine provides the car with excellent sporting qualities. Driving pleasure is at the heart of Infiniti, and this is especially emphasized in Sport equipment, which is now equipped with the active rear wheel steering system RAS. All versions of the FX diesel modification are equipped with an adaptive 7-speed automatic transmission inherited from the FX petrol version with paddle shifters.

The 3.0-liter V6 diesel engine with up to 175 kW (238 hp) was developed jointly by engineers from Infiniti and Nissan. The main goal in creating the engine was to live up to the core values ​​of the Infiniti brand and provide an excellent driving experience.

Especially for this engine, engineers have improved the fuel injection system. Unique engine components include: cylinder block, crankshaft, intake manifold, fuel injection system, exhaust gas recirculation, turbocharger, oil pan and exhaust gas converter in the exhaust manifold.

To get the maximum benefit from compactness, balance and reliability, the turbocharger was placed in the camber of the block (camber angle is 65 degrees). The block heads are made of aluminum alloy, and the block itself is made of compacted gray iron (CGI) and has tremendous strength at a low weight. CGI provides up to 75% higher rigidity than conventional cast iron, and its use in engine block casting results in a 22% weight reduction.

Variable nozzle turbocharger delivers up to 175 kW (238 hp) at 3,750 rpm, putting this engine on a par with the most powerful diesel engines having a single-stage boost. The maximum torque of the new V6 is 550 Nm at just 1750 rpm and is on par with best engine in your class.

The result is an engine with high dynamic characteristics in the area of ​​low speeds and excellent softness of work. It exhibits exemplary throttle response, and while noise levels are kept to a minimum, special setting exhaust system gives it a special sporty "voice", which manifests itself during sharp acceleration at a frequency of about 2500 rpm.

Characteristics of the Infiniti FX30d by layout

The rigid architecture of the vehicle platform ensures the distribution of weight between the axles as in sports car which, combined with the low center of gravity, ensures high stability when cornering. Thanks to the extensive use of lightweight components, including aluminum front and rear doors, the FX30d is one of the lightest in its class.

The double wishbone front suspension combined with the multi-link rear suspension introduced on the FX in 2008 is also used on the diesel model. In addition, on sports version a variable suspension stiffness system (CDC) is used, as well as an active steering system for the rear wheels. Unlike passive systems steering, in active system a high-precision electric drive is used to control the position of the rear wheels, increasing the stability of movement on high speed and maneuverability at low speeds. Steering FX is dependent on vehicle speed and provides excellent feedback to the driver.

The softness and "refinedness" of the engine is emphasized by a smooth seven-speed automatic transmission gear Infiniti. The gearbox parameters are selected in such a way as to fully realize all the benefits of high torque. Adaptive Shift Control (ASC) finely tuned to external characteristic diesel engine and provides excellent dynamics and optimization of fuel consumption. The "D" range provides a smooth and dynamic driving experience, while the "DS" range shifts the shift point to a more high speed. Like on FX with gasoline engines, the diesel version has paddle shifters for precise manual control.

The FX30d features one of the most advanced systems all-wheel drive: Advanced Total Traction Engineering System for All Electronic Torque Split (ATTESA E-TS) – electronic system control the flow of torque to each wheel. The ATTESA E-TS system uses an advanced torque distribution control principle that automatically transfers optimum torque to the wheels according to road and traffic conditions.

The system provides excellent handling thanks to the optimal distribution of torque between the front and rear wheels(from 50:50 to 0:100). ATTESA E-TS also provides high level starting traction and smooth, stable acceleration, especially in snow and off-road conditions with a 50:50 torque split from zero speed.

Infiniti FX30d: brake review

Effective braking is ensured by ventilated disc brakes all 4 wheels, with 4-piston boxer calipers at the front and 2-piston boxer calipers at the rear. Help system for emergency braking(BA) and Electronic Brakeforce Distribution (EBD) are standard on the vehicle.

FX30 Elegance + NAVI AWD, FX30 Sport + NAVI AWD, FX30 Sport Black + Navi AWD also include these options active safety How adaptive cruise control, Collision Warning (FCW) and Intelligent Braking (IBA).

The collision avoidance system provides safe distance to the vehicle in front. When Cruise control turned off, which is what most drivers do, both IBA and FCW are on all the time. Not only do they warn the driver when the distance to the vehicle in front is reduced, but they also pre-pressurise the brakes in preparation for emergency braking.

Athletic appearance Infiniti FX is one of the main factors that determine the decision of buyers when choosing this model. Diesel modification Infiniti FX30 repeats the look petrol versions. Character traits Infiniti FX - a long hood, a developed "shoulder girdle", a window profile like a coupe body. One look at the FX is enough to feel the charisma of this car.

Infiniti FX30d Sales: Prices

The FX's interior is as meticulously crafted as its appearance. The driver-focused cockpit emphasizes the vehicle's sporty character, while precious natural materials and finely crafted finishes create a premium ambiance. As with all 2012 Infiniti FX, dashboard acquired even more effective and sporty look due to the new trip computer screen and white instrument arrows, in addition, the trip computer has become completely Russified.

The FX30d is available in a range of FX30 Elegance trims with accentuated luxury trim and Sport trims with a sporty twist. In Russia, the Infiniti FX3O diesel is available at a price of 2,590,000 rubles, and the prices for gasoline versions of the FX 2012 model year start at 2,574,000 rubles.

Popular materials

This is not to say that Infiniti pays little attention to diesels and focuses on gasoline engines. Many models have their own diesel options, but there are noticeably fewer of them than petrol options. So, for example, the Infiniti QX4 SUV is completely devoid of diesel engines, which, oddly enough, did not affect its sales at all. Nevertheless, this article we will dedicate diesel engine from Infiniti, touching at the end characteristic flaws motors from this manufacturer.

We are talking about a 3-liter V6 diesel engine with direct injection, which was equipped with Infiniti crossover EX30d and the popular M30d sedan with the highest torque in its class at 550 Nm. Special layout engine compartment EX, originally developed for gasoline engines, required a reduction in the size of the diesel, as well as the camber angle of its cylinders, which should be as close to 60 degrees as possible. This was necessary for the location of the engine in both longitudinal and transverse directions. For this, a V-shaped layout with an unusual camber angle of 65 degrees was used. Thanks to this, the engine received the required balance of reliability of the crankshaft, cylinder block and balance, and also got the opportunity to install a turbocharger in the collapse of the cylinders.

One of the main components of the success of the engine from Infiniti was the material of the cylinder block. Traditionally used recently aluminum alloys provided insufficient rigidity and noise reduction. Therefore, compacted gray iron (CGI) was additionally used, which has all the advantages of traditional cast iron, providing, with a slight increase in weight, more high performance rigidity, reduction of noise and vibration. Although gray cast iron is heavier than light alloys, the increase in weight has been minimized by the absence of additional stiffeners, the installation of which was required by the use of light alloy structures.

In addition, there are other original solutions, which allowed the diesel engine to withstand significant loads with solid power and torque indicators. These include a rigid and wide mating surface, an extended lower part of the cylinder block made of gray cast iron, direct attachment of attachments to the crankcase, a special design oil pan and other solutions. All this made it possible to create a powerful, resourceful and compact V9X diesel engine with high structural rigidity and softness in operation, with the lowest vibration rates at frequencies of 250 and 500 Hertz.

As for characteristic features of all Infiniti engines, they are primarily related to the oil level. So, for example, in the FX35 and FX45 models, only 4.5 liters of oil are poured, which requires the driver to constant control for its presence. At the same time, in the same Infiniti FX35, it is extremely poorly located oil dipstick, which is difficult to return a narrow and hard-to-reach neck. With insufficient fixation, the oil can drive the dipstick out and it will be lost while driving. We also note the absence of an oil level sensor in many models, which is why you should even more closely monitor its level and pay attention to the sensor. emergency pressure- slight blinking sharp starts and cornering indicates that it is time to pay close attention to the oil.

Of the most sought after parts and Supplies for Infiniti auto engines, we note the following:

• Ignition coil.

Diesel sabotage in the premium camp. New three-liter engine for Infiniti FX... Should we cry about the death of the Infiniti brand? Let's refrain from it. Although they have gone down to diesel engines, and, who knows, maybe the release of three-wheeled jalopies and pedal tarantasses is just around the corner.

No, it's better to remain silent. Banal, uninteresting. What difference does it make what is produced under brand Infiniti? Why not diesel? Electric motors are coming soon too. However, we remember this brand as a manufacturer of incendiary gasoline bombs. It's gasoline. Which diesel would fit - V10 or V12? No impossible. None at all. Lexus, for example, forgot about diesel fuel and relies on hybrids. Why did Infiniti need this experiment? Actually a three liter diesel nissan cooler than similar Toyota engine, maybe that's why they ignore the hybrid direction? "Nissanovsky" unit mountain-a-a-zdo faster. It reaches a hundred in 8.3 seconds, and with the “Toyota” Infiniti engine, it would have trudged more than 11.

Premium trip. Off-road, it looks like a submarine in the steppes of Ukraine

ALCOHOLIC WITH TOURBILLON
Infiniti is a showy brand. They buy it, if not to blow it up, then at least to shake the reality around them, to set off small tsunamis. Is diesel able to serve in this field? There is a chance. They put similar motors on the Mercedes ML - and nothing, the public drives, everyone is happy. True, the audience is different. Diesel ML for fattening financiers, the kind you can't tell for sure whether they go to bed at nine at night in pajamas or only after eight cans of beer in an unconscious state. They are women or former prosecutors. Everything is shrouded in mystery. Infiniti is more frank. It's not for a mythical character in an alcoholic T-shirt and a tourbillon watch. In general, he is a projection of the owner's appearance: everything that you can say about the appearance of the FX will be true about its owner. Design is above all, and diesel has nothing to do with it. The motor plays no role. However, would the FX initially have become so popular in Russia if it hadn’t hidden five-liter fiery lighters under the hood? Could you reach the level of a semi-cult machine with a tractor unit?

What else does?
Despite the complete lack of ergonomics, the Infiniti interior invariably brings joy and light.

MISSING IN TURNS
Marketers from Nissan behave strangely. First, they work on the image of a daring chassis with a pronounced rear-wheel drive accent, which is depressing in winter on ice, but fascinates in turns on dry land. Then they put wide wheels, such that when braking, you need to vigorously work with the steering wheel, compensating for body pulls. In other words, they do everything to pass for the scumbags of the auto industry. As a result, the spiritual brotherhood of Infiniti fans is already reminiscent of a sect. Such, you know, a simple sect of car owners who are addicted to spying on hermaphrodites frolicking in a bath of quail fat, or organizing races for the spirits of Eric Kurmangaliev and Boris Yeltsin in the tunnels under the Sparrow Hills. And at the peak of this paranoia, Nissan brings into the banquet hall a three-liter black-fuel engine, practically removed from a corn harvester. I imagine the faces of the participants in the feast. No, diesel engine positively unsuitable for Infiniti, and we will not talk about it anymore. Stop talk about this.

Circles before the eyes. Get out of here blue backlight- and the devices will completely lose their individuality

OBLOMOVSHINA
It remains only to drive on the new three-liter FX. Feel what is what and how, and tell you about your feelings. I sit down, start the engine, go and ... well, nothing. The sound is a strained diesel rumble. gasoline engine sings much more beautifully and more pleasantly. Where has the nobility gone? There is some kind of unnaturalness in this whole undertaking with a diesel engine, as if they were pulling balloon to the globe. I already wrote about this diesel when we tested Nissan Pathfinder. His character is like that of Oblomov: maybe, but he doesn’t particularly want to. It would be impressive for him to pull a trailer ... It is great for universal SUV, but for premium crossover... Yes, he has a big plus - he eats a little, less than 12 liters per hundred, but after all, the German rationality does not suit the bullfighter, on whom FX is drawn as a projection of the owner. Maybe it's in vain that the Infiniti brand ignores the topic of hybrids?

Infiniti- Japanese manufacturer luxury cars, leading its history from not too distant 1989. This brand is a premium division of Nissan and was created to compete with Acura and Lexus in North American, and later in other markets.
By analogy with other Japanese premium brands, almost every Infiniti model has its analogue in the Nissan range, or is based on the Nissan base.

Infiniti engines are the same Nissan engines(less often Mercedes-Benz), but exceptionally large and powerful, as befits a luxury car. The most modest models are equipped with turbocharged inline fours from Mercedes and Nissan's V6 called the VQ25, as well as the popular VQ35 and VQ37. The last two motors are extremely common and are found on many models of the brand. under the hood big sedans and off-road vehicles are hiding fairly large V8s such as the VK45, VK50 and VK56.
As for the old models, in the 90s, a 4-cylinder SR20DE was installed on Infiniti, as well as VG30, VH45, VH41 and other engines.
Diesel engines are not often seen, but some models are equipped with a 3-liter V9X and OM651 from Mercedes with a displacement of 2.1 liters.
Infiniti hybrid engines are gaining popularity and are increasingly being installed instead of conventional gasoline power plants. Their range consists of VQ35HR and QR25DER.
Also on sports models of this brand, a smaller version of the GTR engine is installed, which is referred to as VR30DDTT.

By selecting your car model from the list below, you will find reviews and specifications Infiniti engines, their differences from each other, what modifications were produced and on what cars they are found. In addition, you will learn the main shortcomings, diseases, problems and repairs of Infiniti engines, their resource, how much oil is in the engine, what kind of oil should be used and how often it should be changed.
