In racing applications, slipper piston skirts can be configured to yield extremely light weight while maintaining the rigidity and strength of a full skirt. [5] Reduced inertia also improves mechanical efficiency of the engine: the forces required to accelerate and decelerate the reciprocating parts cause more piston friction with the cylinder ...
To lower the maximum piston/conrod acceleration, Formula One cars use short-stroke, multi-cylinder engines that result in lower average piston speed for a given displacement. [12] After seeing some 16 cylinder engines, [ b ] the number of cylinders was limited to twelve in 1989, ten in 2000, eight in 2006 and six in 2014.
The British Racing Motors V16 is a supercharged 1.5-litre ... but had become a necessity on high-powered piston aero engines such as the Merlin and Griffon.
Nismo used the VK56DE for FIA GT1 racing in the Nissan GT-R GT1 from 2010 to 2011. In race trim, it produced 600 hp (447 kW) and 650 N⋅m (479 lbf⋅ft) of torque. [6] The Nissan Motorsport VK56DE was launched in Australia for the V8 Supercars Championship in 2013 by Kelly Racing in Melbourne. The engine has been reduced in capacity to 4,990 ...
The Rolls-Royce Merlin is a British liquid-cooled V-12 piston aero engine of 27-litre (1,650 cu in) capacity. Rolls-Royce designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12, it was later called Merlin following the company convention of naming its four-stroke piston aero engines after birds of prey ...
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats.
