V5 engine

A V5 engine is a five-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration.

V5 engine designs are very uncommon, with the only production version of one being the 1997-2006 Volkswagen Group VR5 engine.

Automobiles

General Motors

In the early 1980s, Oldsmobile developed a prototype 2.5 L (153 cu in) V5 diesel engine, however it never reached production stages and the project was subsequently abandoned.[1] The engine is based on the Oldsmobile V6 diesel engine with the fuel injection pump in the location of the "missing" sixth cylinder.[2] A prototype engine is on display at the RE Olds Museum in Lansing, Michigan.

Volkswagen group
Main article: VR5 engine

The only V5 engine to reach production was the 2.3 L (140 cu in) "VR5" engine produced by Volkswagen from 1997–2006. Based on Volkswagen's VR6 engine, the VR5 was a narrow-angle engine with staggered cylinders (three cylinders on one bank and two on the other) sharing a single cylinder head.[3] As per the VR6 engine, the angle between the banks was 15 degrees. Initial versions used 2 valves per cylinder, however, an update in 2000 resulted in a total of 4 valves per cylinder and the addition of variable valve timing.

Motorcycles

The Honda RC211V, a MotoGP racing motorcycle which competed in the 2002–2006 seasons, used a V5 engine.[4] The transversely-mounted 990 cc (60 cu in) engine had three cylinders at the front, two cylinders at the rear and a V-angle of 75.5 degrees. The engine used 4 valves per cylinder.

gollark: The UK's university applications system is so annoying and ridiculous. I am having to do a *lot* of work comparing university entry requirements and looking at UCAS data because some utter bee thought "hmm, what if you apply *before* actually having exam grades?".
gollark: .
gollark: Look up RSA-2048 or something
gollark: It's a product of two prime numbers. In general, prime factorisation is much harder than generating arbitrary primes and multiplying them.
gollark: I really feel like you're not making efficient use of this.
