V16 engine

The sixteen- cylinder is a type of reciprocating piston engines, particularly internal combustion engines.

Description

Types

Sixteen cylinders are used almost exclusively as a water-cooled V-engines are used, since they would build as a series motor is very long and would pose great challenges in the manufacture of the crankshaft, or engine block. In addition, U, W and H- structures were realized, in which two independent eight-cylinder were connected to each other.

The motors can be both petrol and designed as a diesel engine.

Applications

Sixteen -cylinder engines are mainly used as large engines in diesel locomotives, dump trucks, large excavators, motor vessels and power plants. In small numbers they are also used for a few car models of the upper class, super sports cars and racing cars, and airplanes. However, these are mostly small series or unique pieces.

Quietness

Sixteen -cylinder V- engines have by their high number of cylinders a very smooth running, because in them the forces of inertia are even better than in V engines balanced with a smaller number of cylinders.

Only in an exceptional case, the Cizeta V16T supercar, the V16 has a different crankshaft offset or firing order. Therefore, the running noise is slightly less cultured, since this engine was designed with more emphasis on achieving very high speeds as on refinement.

Automobiles with sixteen cylinder engines

  • Alfa Romeo built in 1935 for the Grand Prix race cars Bimotore 1935, The drive, however, of two separate eight-cylinder in-line engines (one each at the front and at the rear) existed. This car reached up to 325 km / h and made ​​up to 540 hp. A successor model of this vehicle from the years 1938 and 1939, the Grand Prix single seater Tipo 316, then had a real V16 engine, which made ​​440 hp and the car accelerated to 300 km / hr. The completion of the development of sixteen -cylinder engines in Alfa Romeo eventually formed the Grand Prix single seater Tipo 162 from the years 1939/40, with an output of 490 hp and driven by the same motor racing sedan Tipo 163 of 1941. Both vehicles which each had a V16 engine with four in the head 90 ° inclined valves per cylinder, only one copy was built.
  • Bugatti built in 1929 the T -45 racing car with sixteen cylinder engine. The engine was based on a design that Ettore Bugatti had developed in the last years of the First World War as an aircraft engine. It consisted of two separate, juxtaposed series of eight cylinders each with its own crankshaft. The crankshafts were connected by a date in the middle of bevel gears. This design was referred to as U-16 engine. The capacity amounted to 3.8 liters; each cylinder had three valves. By 1930, two units were built; a vehicle was used in the factory in uphill races. Another sixteen- cylinder model, the T47, was designed as a grand sports car, but was never completed.
  • Cadillac built in the 1930s, two different types of a sixteen -cylinder engine: From 1930 to 1937 7.7 -liter V16 was produced from 1938 to 1940, an engine with 7.4 liter displacement. The vehicles were with different bodies - offered by various manufacturers - coupes, roadsters, sedans; per year less than 100 copies were usually made and sold.
  • From 1931 to 1933, 8.0 -liter V16 engine, which was intended as a Cadillac competitor, but overall, reached only a very small spread was at Marmon. Contemporary accounts attributed Marmon Sixteen -cylinder engine an even greater smoothness to the Cadillac design.
  • The Auto Union racing cars of the 750 - kg class came in the 1930s V16 engines. Initially (1934 ) made ​​the V16 295 hp 4.4 liter displacement (type A), 1935 373 hp ( type B) and 1936 from 6 liters of engine capacity 520 hp ( type C) were obtained from 5 liters of displacement.
  • 1931 was the Bucciali Double - Huit presents In France, a product still not entirely clarified history. In particular, it is not clear whether the engine was in working order and - if so - how many copies were made ​​.
  • In Britain, the BRM team developed 1950 and 1966 each have a sixteen- cylinder engine for use in Formula 1, the V16 engine for 1950 to 1952 was extremely small with a displacement of 1.5 liters and also still charged by a two-stage centrifugal compressor of Rolls- Royce. He served in 12000/min around 440 kW and was the competition, as measured by the performance, vastly superior but on the other hand, very vulnerable, often leading to failures. The best by the BRM P15 (the car in which the V16 was installed ) ever reached Formula 1 result was finally achieved fifth place in the Grand Prix of Great Britain 1951. The second sixteen -cylinder engine of BRM was designed as an H -16 motor and consisting of two superimposed V8 engines, each having a cylinder angle of 120 degrees. The engine was very difficult and in the words of historian David Hodges Motorsport " hopelessly unreliable" ( "desperately unreliable "). The engine was installed in the racing car BRM P83 and used by the BRM factory team from late 1966 to early 1968 in a total of 32 races. The overweight car - there was talk of 135 -kilo weight - came only twelve times to the finish; the best result was a second place of Jackie Stewart.
  • In Switzerland, Sbarro developed the model 1976 Royale. Externally, the designed as four-door Sedan car the Bugatti Type 41 ( " Bugatti Royale " ) was modeled; specifically the 1933 Park Ward designed for the chassis 41-131 body had served as a model. The vehicle was driven by a sixteen cylinder engine, the Sbarro produced by joining two eight-cylinder engines from Rover. The Sbarro Royale was produced at the request of a customer from the Arab region and remained a one-off.
  • In Italy, was produced from 1991 to 1995 Cizeta V16T of.
  • In 2003, Cadillac introduced the prototype Cadillac Sixteen, which should remind you of the V16 from the 30s. The car was equipped with a 13.6 -liter V16 engine. He never went into production.
  • The Bugatti Veyron 16.4 manufactured since 2005 has a W -16 engine.
  • 2006 was built by the German manufacturer Isdera as a single piece of the Isdera Autobahnkurier 116i. Is powered by the 2 2- seater sports car in the style of the 30's of two V8 engines, which together have 10 liters of displacement.
