10 Most Unusual Automobile Internal Combustion Engines Single cylinder engineIn 1885, Karl Benz introduced the world to his invention - the Benz Patent-Motorwagen - the world's first ICE car. The vehicle was equipped with a four-stroke power plant with one cylinder and a volume of 954 cm / cu. After 9 years, 25 cars were produced with the same engine, but with a power of 1.5, 3 “horses”.Rotary piston engineThe RE(Rotary Engine) or Wankel engine gained fame thanks to the Mazda brand. The idea of the invention belongs to Valtor Freud, and its co-author, self-taught engineer from Germany, Felix Wankel, brought it to life. Development was carried out within the walls of the company NSU Motorenwerke, subsequently purchased by the Volkswagen Group. Not only cars were equipped with such engines, but also Norton and Suzuki motorcycles.
In 1991, the Mazda 787B, equipped with a four-rotor engine with a capacity of 700 horsepower, won the “24 hours of Le Mans”, becoming the only car that managed to get around its rivals, having an RE under the hood. This was the first and last triumph of the rotary piston engine - a year later, the cars equipped with this type were banned from participating in competitions.V16This type of engine could not withstand competition from the side of 8 and 12-cylinder engines with similar power characteristics.The first V16 began to install Cadillac in the 30s of the XX century. Then the baton was picked up by the sports car Cizeta V16T. Used 16-cylinder power plants and sedans on the 7th series of the BMW 767iL series E32, Alfa Romeo Tipo 316 and 162 race cars, as well as Auto Union cars.

V-Twin or V2A 2-cylinder V-engine is well known to Harley-Davidson, Indian, Suzuki, Honda, Aprilia, Kawasaki and Yamaha bike lovers.But few people know that in the 20s of the XX century it was installed in passenger cars. In the 60s, Mazda launched the Citicar R360 with V2. Now only the "Morgan 3 wheeler" tricycle boasts such an original power plant.
Gas turbine engineThe time has come to mention other types of engines - gas turbines, a striking representative of the family of which is the A-831 engine, installed under the hood of the 1963-64 Chrysler coupe from Carrozzeria Ghia S.p.A.
It is noteworthy that the car could drive any fuel that could ignite: from gasoline with diesel fuel, to alcohol and perfume. Engine power reached 130 liters, and the turbine could accelerate to 60 thousand revolutions per minute.
Cars successfully passed tests, however Chrysler was forced to remove products from the conveyor. Further work on the project became impossible due to the financial problems of the company.V5Such famous European brands as Audi, Volvo, Mercedes-Benz and Fiat quite often put engines with 5 cylinders on their models. Moreover, they were all single-row. The V-shape of a 5-cylinder engine is rare.
So, in 1997 Volkswagen used its own 2.3-liter power unit VR5, developing a capacity of 150 “horses”.
Single row 8-cylinder
At the threshold of the 20th century, engines of this type were often used, especially in the USA. However, over time, automakers began to give preference to more compact V-shaped motors.
On the European continent, the 8-cylinder single-row engine was first tested by Daimler. Gradually, this trend was adopted by Bugatti and Opel, Duesenberg and Alfa Romeo. With the “eight” under the hood was the celebrated Mercedes-Benz 300 Sport Leicht-Rennen (SL-R) - the same one driven by Sir Stirling Crofard Moss won the Mille Miglia endurance race in 1955.
V4
One of the rarest representatives of the family of power plants. However, a number of automakers installed 4-cylinder engines on their products. Among the pioneers was a sports car Mors. A little later, similar engines began to be used on the Lancia Lambda and Fulvia. Also, such units were installed on the 1962-82 model Ford Taunus and Saab. Among the latter was the Porsche, which uses 2 liter engines in hybrid units. It was on such an engine that the famous 919 Hybrid was able to win the Le Mans 24-hour race.H16The invention belongs to British Racing Motors and is an H-shaped installation of two boxer engines.It was this unit that stood on the Formula 1 BRM P83 car of the 1966-67 season, which was controlled by pilots Graham Hill and Jackie Stewart. The Lotus 43/1, piloted by Jim Clark, was equipped with a similar installation. In 1966, he managed to win the US Grand Prix.W8 Initially, this arrangement of cylinders was used by the Volkswagen Group. Thus, the Volkswagen Phaeton, Touareg, Audi A8 and Bentley Continental GT were equipped with a W-shaped engine with 12 cylinders and a volume of 6 liters.In 2002, the Germans adopted the technology, equipping the Passat with all-wheel drive with a similar unit. The motor had a volume of 4 liters and developed a capacity of 270 “horses” with a torque of 370 Newton Meter. Structurally, it was a combination of two V-blocks with 4 cylinders each. The idea is interesting, that's just reliability failed.
