V5 engine

Last updated

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

Contents

Even by contrast to the fairly rare straight-five engine, V5 engine designs are very uncommon. The first production V5 was the 1997–2007 Volkswagen Group VR5 engine. It is arguably not a true V5 engine, as all the cylinders share a single cylinder head. However, Honda produced a true V5 motorcycle racing engine, used in the RC221V.

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

The only V5 automobile engine to reach production was the 2.3 L (140 cu in) "VR5" engine manufactured by Volkswagen from 1997 to 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

Honda

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.

BSA

In the last days of the BSA motorcycle manufacturer, the factory design team produced plans for a modular range of four engines, all using a 200cc cylinder. (It was planned to increase the cylinder capacity to up to 250cc in due course). The range, which never went further than the drawing board, comprised:

(The company avoided the perhaps obvious 800cc straight-four option, to avoid direct competition with the major Japanese factories that already dominated the market with such machines). [5]

<span class="mw-page-title-main">Cylinder head</span> Component of an internal combustion engine

In a piston engine, the cylinder head sits above the cylinders, forming the roof of the combustion chamber. In sidevalve engines the head is a simple plate of metal containing the spark plugs and possibly heat dissaption fins. In more modern overhead valve and overhead camshaft engines, the head is a more complicated metal block that also contains the inlet and exhaust passages, and often coolant passages, Valvetrain components, and fuel injectors.

<span class="mw-page-title-main">VR6 engine</span> Reciprocating internal combustion engine

The VR6 engine is a six-cylinder engine configuration developed by VW. The name VR6 comes from the combination of German words “Verkürzt” and “Reihenmotor” meaning “shortened inline engine”. It was developed specifically for transverse engine installations and FWD vehicles. The VR6 is a highly compact engine, thanks to the narrower angle of 10.5 to 15 degrees between cylinder banks, as opposed to the traditional V6 angles ranging from 45 to 90 degrees. The compact design is cheaper to manufacture, since only one cylinder head is required for all six cylinders, much like a traditional inline-6 engine.

<span class="mw-page-title-main">Honda NR</span> Type of motorcycle

The Honda NR was a V-four motorcycle series started by Honda in 1979 with the 500cc NR500 Grand Prix racer that used oval pistons. This was followed during the 1980s by a 750cc endurance racer version known as the NR750. The oval piston concept allowed for eight valves per cylinder which generated more power due to the increased air/fuel mixture and throughout compression. In 1992 Honda produced around 300 street versions of a 750cc model, the NR, with a 90-degree V angle. Whereas the NR500 had used an oval piston with straight sides, the road going NR750 used an elliptical piston with curved long sides. The bike became the most expensive production bike at the time when it was selling for $50,000 and with the rarity, nowadays they rarely change hands.

Honda won ten 500cc World Championships with the NSR500 from 1984 to 2002, with six in a row from 1994 to 1999. With more than 100 wins to its credit, the NSR500 is the most dominant force in modern Grand Prix motorcycle racing. The 1989 NSR500 that won Honda's third 500 World Championship with Eddie Lawson exemplifies the overwhelming power, acceleration and raw speed that has always been synonymous with Honda's 500 cc two-stroke V4.

The VR5 engines are a family of petroleum fuelled Internal combustion engines developed by the Volkswagen Group and produced from 1997 to 2006. They are derived from the VR6 engine family, also developed by Volkswagen, but with one fewer cylinders. The VR5 is highly compact, thanks to the narrower angle of 15° and a displacement of 2,324 cc. The VR5 was the first production block to use five cylinders in a VR design with a 15-degree angle.
