On various ships you can find many options for such diesel engines, however special attention deserves a Wartsila-Sulzer engine, and more precisely the model RTA96-C.
We note right away that today the specified unit can rightfully be considered the largest and most powerful engine in the world, and the installation also has the largest engine size compared to similar counterparts. So, first things first.

Diesel giant: characteristics
The Finnish manufacturer Wartsila occupies a leading position among companies that specialize in the development and production of marine diesel engines. The units have a high unit power.
The first Wartsila - Sulzer engine with the RTA96-C index received 11 cylinders and appeared back in the 90s. The internal combustion engine is a two-stroke marine diesel engine and was assembled at the facilities of the Japanese company Diesel United.
Then in 2002, the availability of a 14-cylinder version was announced. We add that today the company manufactures several variants of such internal combustion engines. The main difference is the number of cylinders, which can be from 6 to 14, while general design practically the same. It is noteworthy that the cylinder diameter in such an internal combustion engine is 960 mm, and the stroke is as much as 2.5 meters.
As for the working volume, the indicator is fixed at around 1820 liters. As a rule, this diesel engine with a different number of cylinders is placed on large ships with a capacity of about 8,000 or 10,000 tons, which transport containers (container ship). This marine diesel generator is the main power plant, allowing the ship to reach a speed of 25 knots, which is just over 45 km/h.
The total power of the RTA96-C is at around 108920 hp. with a working volume of 25480 liters. If we consider the power of such a diesel engine when converted to 1 liter of fuel, we get a little more than 4 hp. per liter of fuel. At first glance, this is quite a bit. Moreover, it is no secret to anyone that car engine manufacturers have long been removing at least a hundred “horses” from 1 liter.
However, it is important to understand that reduced power at this displacement is an intentional step. The fact is that a marine diesel engine is “low-speed” and very reliable, the revolutions at reaching maximum power have a frequency of only 102 rpm, while automobile diesel internal combustion engines rotate with a frequency of about 3-4 thousand rpm.
Such a slow and quiet operation of the unit on the ship allows for improved filling and ventilation of huge cylinders, the piston speed is also low, but the motor is not bad at the same time. In practice, this means that the fuel consumption in this engine in all modes is 118-126 grams of diesel fuel per 1 hp. at one o'clock. This figure is actually one and a half or even two times lower compared to diesel engines in cars.
Compressors pump air through coolers to special "windows" that are made at the bottom of the cylinder. These windows open when the piston reaches BDC (bottom dead center) and allow air to pass through. A special (crosshead) mechanism is also used to transfer force from the piston to the crankshaft. This decision allows, as well as reduce the weight of the unit.
This approach is fully justified, taking into account the peculiarities of fuel ignition in a diesel engine, high loads on a diesel engine, the vibration load of the installation, and the need to ensure maximum durability. All the parts from which the most big engine, made using proven and durable metals. Traditional solutions are cast iron and steel.
What is the result
Finally, we add that despite the great success in the production of heavy-duty marine diesel engines, Wartsila engineers do not intend to stop there.
The evidence is the information that work is underway to create even more powerful marine engines. internal combustion. For example, statements about the development marine diesel with 18 cylinders.
This means that in the near future, against the background of diesel generators already in the line, an even more powerful internal combustion engine with impressive dimensions and characteristics will appear. In other words, soon the next largest engine in the world will be put into operation.

You can argue for a long time about which engine is the most powerful in the world. Therefore, there is a division into cars and not passenger motors. Most powerful engine in the world - Wartsila-Sulzer RTA96-C, which is installed on ships. Among cars there is the top ten, which we will consider, in this article.
The history of the engine
The development lasted almost two centuries, until motorists can recognize the prototypes modern motors. It all started with gas, not gasoline. Among the people who had a hand in the history of creation are Otto, Benz, Maybach, Ford and others.
But, the latest scientific discoveries have turned the whole auto world upside down, since the wrong person was considered the father of the first prototype.
According to historical facts, in the 17th century, the Dutch scientist and physicist Christian Hagens developed the first theoretical internal combustion engine based on gunpowder. But, like Leonardo, he was shackled by the technologies of his time and could not make his dream a reality.
France. 19th century. The era of mass mechanization and industrialization begins. At this time, it is just possible to create something incredible. The first who managed to assemble an internal combustion engine was the Frenchman Nicéphore Niépce, which he named Piraeofor. He worked with his brother Claude and they have been together until creation of ICE presented several mechanisms that did not find their customers.
In 1806, the presentation of the first motor took place at the French National Academy. He worked on coal dust and had a number of design flaws. Despite all the shortcomings, the motor received positive reviews and recommendations. As a result, the Niepce brothers received financial assistance and an investor.
The first engine continued to develop. A more advanced prototype was installed on boats and small ships. But this was not enough for Claude and Nicephorus, they wanted to surprise the whole world, so they studied various exact sciences in order to improve their power unit.
So, their efforts were crowned with success, and in 1815 Nicephore finds the works of the chemist Lavoisier, who writes that "volatile oils", which are part of petroleum products, can explode when interacting with air.
1858 Belgian scientist and engineer Jean Joseph Etienne Lenoir collects two stroke engine. The distinguishing elements were that it had a carburetor and the first ignition system. The fuel was coal gas. But, the first prototype worked for only a few seconds, and then failed forever.
This happened because the motor did not have lubrication and cooling systems. With this failure, Lenoir did not give up and continued to work on the prototype, and already in 1863 the engine, installed on a 3-wheeled car prototype, drove the historical first 50 miles.
All these developments marked the beginning of the era of the automotive industry. The first internal combustion engines continued to be developed, and their creators immortalized their names in history. Among these were the Austrian engineer Siegfried Markus, George Brighton and others.
Rating of the most powerful passenger cars
Man is always striving to improve his creations. internal combustion is no exception. Therefore, today there are a number of internal combustion engines that already have power characteristics in excess of 1000 horsepower. So, let's look at the rating of the most powerful passenger cars in the world.

Conclusion
by the most powerful motor in the world is considered to be the Wartsila-Sulzer RTA96-C with its 110,000 horsepower. Among passenger cars, Koenigsegg Regera confidently holds the championship.
Any engine is a specially designed unit in which fuel is burned, and due to this, a driving force is created. Today there are many different types engines, and the most powerful of them are used in naval ships and rockets. Similar developments are present in other industries, including motorcycle and automotive industries. We present you a selection of the 10 most powerful engines in the world.
You probably thought that the most powerful motorcycle is famous Harley Davidson? But no! A 2.3 liter engine with a capacity of 140 horsepower and water cooling is installed on a brand motorcycle. At the same time, the model is mass-produced, so that anyone who wishes has the opportunity to test it.
Concern Chrysler Group- so far the only one who can boast of the most powerful car engine. This is exactly what is installed in the car. The volume of its engine is 8.4 liters, and its power is 649 horsepower, which provides acceleration to 100 km / h in just 3 seconds.
Just imagine how 5,000 horses are pulling a huge airliner into the sky. Difficult? A aircraft engine does it twice! With a volume of 127 liters, the unit weighs 2740 kg. There are only 36 such engines in the world, and they are the largest in their class.
In order to take full advantage of wind energy and convert it into electricity, it was invented. And the largest one is installed in the Atlantic port of Nantes-Saint-Nazaire, in France. The diameter of the wind turbine is 154 meters, and its power is 6500 kW, which is equal to 8046 horsepower. At the same time, in order for the blades to start spinning, the wind speed should be only 3 m / s.
Not only our modern scientists and designers can do something “the very best”. In 1941, a steam locomotive was built with 26 meter motor, thanks to the traction force of which (more than 6,000 horsepower) maximum speed was 100 km/h.
In 1955, the most powerful railway locomotive was created with several turbocharged engines. Their combined power was 8500 "horses", and this locomotive record has not yet been broken.
Push-pull dimensions diesel engine turbocharged RT-flex96C impressive: its length is 13.5 meters, and its height is 26.5. Dimensions power is not inferior: it will equal 108,000 horsepower. The engine is designed for marine vessels and burns 6.3 tons of fuel oil in just one hour.
One of the advantages of modern turbo engines is the combination of low weight and colossal power. One of the representatives of this class is the engine, which is installed in aircraft carriers that develop cruising speed. The weight of the unit reaches 8 tons with a capacity of 330,000 "horses".
To install and run the engine, you will need a power plant. This unit converts wet steam into electrical energy, and its power is no longer thousands, but millions of horsepower - 2,346,788!
Want to go on a space trip to the moon? In that case, without rocket engine with a capacity of 190,000,000 horsepower you can not do without. It produces so much energy that it would be enough to light up the whole of New York for 75 minutes. The engine will be able to deliver into orbit not only you, but also more than 130,00 kilograms of cargo. The most meticulous experts have calculated that the fuel that the unit consumes is enough for 800 car trips around the globe. 
It is quite natural that in automotive industry completely different power units are used, which differ from each other in the number of cylinders, volume, the presence of supercharging and power.
Today we bring to your attention an impromptu rating of the most powerful engines in terms of the number of cylinders in the world: from the small two-cylinder engine of the FIAT 500 model to the mighty W16 unit, which is used on the Bugatti Chiron hypercar.
For a fair comparison, we do not include hybrids in this list. power plants, because their electrical impulse distorts the results too much. For example, the 1.6-liter V6 engine of a Mercedes-Benz hypercar Project One with four electric motors, it is capable of generating about 1100 hp, which would give it a leading position.
Note that all power units included in the rating of the top most powerful engines in terms of the number of cylinders are currently used on production cars. That is, our hit parade is as relevant as possible. So. If you ever wondered which is the most powerful car engine for a given number of cylinders, then our rating gives the answer.
2 cylinders - FIAT 0.9 TwinAir
This is an amazing thing, but the small 0.9 TwinAir turbo engine used on compact model FIAT 500 is capable of generating 103 horsepower. Note. Although this figure is the winner in automotive world, in the motorcycle world there are more efficient motors. For example, a V2 power unit with a volume of 1285 cubic centimeters Ducati models 1299 Panigale R FE puts out … 207 horsepower.
At the time of this writing, the 1.0-liter EcoBoost engine from the American Ford 136 hp is the most powerful three-cylinder engine you can buy. However, this result will be surpassed in the most soon: Fiesta ST will soon be available in Europe this fall with a 1.5-litre three-cylinder engine producing 197 hp.
4 cylinders - Mercedes-AMG 2.0 The four-cylinder 2.0-liter supercharged Mercedes-AMG engine is capable of delivering 375 horsepower. As you know, this unit is used on models such as CLA-Class, A-Class and GLA-Class. This figure is impressive, but it is not the best ever. In 2014 Japanese company Mitsubishi offered the Evolution X FQ-440 MR model, which was equipped with a 4-cylinder 440-horsepower engine. The circulation of the car was limited to only 50 copies.
12 cylinders - Ferrari 6.5 V12 The most powerful 6.5-liter 12-cylinder engine is installed in the recently introduced Ferrari 812 Superfast coupe, where it generates 789 (800) horsepower. Thanks to a powerful unit and an optimally tuned chassis, the car is able to accelerate from 0 to 100 km/h in just 2.9 seconds.
16 cylinders - Bugatti 8.0 W16 There are not many cars in the global automotive industry that are equipped with 16-cylinder engines. Therefore, it is obvious that the most powerful 16-cylinder engine in the world is the four-turbo Bugatti engine, which is capable of generating 1,500 horsepower. However, it is worth recalling that there is such a machine as the Devel Sixteen, which is equipped with a V16 engine, the power of which can vary from 3000 to 5000 horsepower. However, this car has not yet gone into production, but the engine actually exists.
Shipping companies around the world are increasingly ordering Supertankers and Containerships from shipyards. This is a booming sector of the shipbuilding market. These ships require more and more perfect stuffing, including marine engines. And it is for such ships that diesel-powered construction plants in Finland are building the world's largest single ship ICE power about 100 thousand kW.
Wartsila is one of the world leaders in the field of marine diesel engines of large unit power. Since the 1990s
she developed the Wartsila - Sulzer - RTA96-C range of marine engines. These are two-stroke marine diesel engines. Ruler -
this is because the shipowner can order such a marine engine from 6 to 14 cylinders.
Structurally, these marine diesel engines are very similar.
This cylinder diameter marine engine 960 mm, piston stroke - 2.5 meters! The working volume of the diesel cylinder is
1820 liters. About other characteristics - a little later. For now, let's say that there are about a hundred such marine diesel engines in 8, 9,
10, 11 and 12-cylinder versions were installed on container ships.
A vessel with a capacity of 8 - 10 thousand tons, driven by the only such marine diesel generator, is quietly developing
25 knots (more than 46 kilometers per hour).
The first marine engine of the Wartsila - Sulzer series - RTA96-C (11-cylinder diesel) appeared in 1997. His
manufactured by the Japanese company Diesel United. And in 2002, Finnish designers announced the availability
14-cylinder marine diesel engine Wartsila - Sulzer.
Now about her records in more detail. Wartsila (Wartsilya) - Sulzer (Sulzer) - RTA96-C reaches 108 thousand 920
Horse power. The working volume of this marine diesel generator is 25 thousand 480 liters. Liter power
diesel is unusually low - about 4.3 "horses" per liter.
Say, this is really strange, because in modern automotive turbocharged diesel engines, engineers have learned to "remove" from
liters more than 100 horsepower. However, relatively low power with such a gigantic size was not chosen
easy. Large marine engines Wartsila - Sulzer (Sulzer) work with dignity, slowly (by the standards of conventional
ICE) gaining air into their giant "lungs".
The shaft speed at maximum power for this marine diesel engine is only 102 rpm
(against 3-5 thousand revolutions for passenger diesel engines). This ensures good gas exchange in a diesel engine (imagine what
volumes of air to be pumped), comparatively low speeds piston in the engine, and all together - good efficiency.
In the mode of the smallest specific consumption fuel (not full power) it exceeds 50% (apparently, this is a record for
serial internal combustion engines). And at full load, the efficiency of the engine is not much lower. The specific fuel consumption for all
modes fluctuates around 118-126 grams per horsepower at one o'clock; which is 1.5-2.5 times lower than that of automobile
diesels.
Comparing the numbers, keep in mind that these marine diesel engines run on heavy marine diesel fuel with a much lower
energy content than automotive counterparts.
14-cylinder Wartsila - Sulzer (Sulzer) 14RTA96-C (this is the full name of the marine diesel engine) weighs 2300 tons in
dry (without oil and other technical fluids). Weight crankshaft amounted to 300 tons. Ship length
diesel engines reaches - 26.7 meters, and height - 13.2 meters.
Of the engineering features, it should be noted that in each cylinder of a marine diesel engine there is a single,
located in the center of the combustion chamber, a giant valve. There are three more small valves (analogues of nozzles in
conventional motors) for direct injection diesel fuel into the cylinder of a marine engine.
This huge valve is the outlet. From him traffic fumes go to a common collector and then to four
turbochargers. Those, in turn, drive fresh air through the coolers and to the windows cut out at the bottom.
cylinder. The latter open when the diesel piston descends to bottom dead center.
As in many marine diesel engines, the force from the piston to the crankshaft is transmitted here by a crosshead mechanism. This
increases the durability of a marine diesel engine. And the company is also proud of the low weight of its marine diesel engines.
Think about the stresses placed on diesel components, the stringent vibration requirements, and the required durability of such a
engine (imagine replacing a similar marine diesel engine with a giant container ship).
The main material for the construction of this marine diesel engine was traditional cast iron and steel.
So the work and talent of the creators of marine diesel engines Wartsila (Vyartsilya) deserves the deepest respect.
Meanwhile, the team of designers Wartsila (Vyartsilya) is working on the creation of more powerful marine internal combustion engines. Has already
mention regarding the development of an 18-cylinder version of their heavy duty marine diesel.
So. Facts about the 14 cylinder version:
Weight: 2300 tons ( crankshaft only 300 tons)
Length: 27 m
Height: 13.4 m
Max Power: 108,920 hp at 102 rpm
Maximum torque: 7,907,720 Nm at 102 rpm
Fuel consumption: more than 6,283 liters of heavy fuel per hour
