12 CYLINDER V-Engine
What engine is the 12 cylinder V-engine: 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.
What is the 12 cylinder V-engine displacement: it is in a range between 3500 cc and 7312 cc in recent model line up powertrain.
How much is the power of the 12 cylinder V-engine: the power of the 12 cylinder v-engine is in a range from 264 bhp to 860 bhp.
Which cars use 12 cylinder V-engine: V12 engines are much less common than V8 but more used than V10 engines. In the last 50 years these are the automotive manufacturer that engineered and built V12 engines:
Jaguar: V12 engine was an all-aluminium SOHC design with displacements of 5.3–6.0 L (323–366 cu in) that was produced from 1971 to 1997 in the E-Type, XJS, and XJ.
BMW: Production of V12 engines began with the BMW M70 SOHC engine introduced in the 1987 E32 7 Series luxury sedan. The engine was also used in the E31 8 Series. The engine was upgraded to a DOHC V12 engine in 2003, then to a turbocharged DOHC V12 engine which has been in production from 2008 to the present in the 7 Series. BMW V12 engines have also been used in several Rolls-Royce models, beginning in 1998.
Mercedes-Benz: the company's first V12 engine was the Mercedes-Benz M120 engine, a 6.0 L (366 cu in) DOHC engine introduced in the 1991 Mercedes-Benz 600 SE luxury sedan. This engine was replaced by a SOHC V12 engine in 1998, then a turbocharged SOHC V12 engine which has been in production for 2003 to the present.
Aston Martin: the 1999 Aston Martin DB7 V12 Vantage used the company's first V12 engine, a 5.9 L (362 cu in) DOHC design. Variations of this engine were used in the Vanquish, DB9, DBS V12, Rapide, Virage, and V12 Vantage. This engine was replaced by a turbocharged DOHC V12 engine, which was introduced in the Aston Martin DB11 and has been produced from 2016 to the present
Audi: the 2008–2012 Q7 SUV was powered by the Audi 6.0 V12 48v TDI engine, which was the first V12 diesel engine used in a production car
Toyota: V12 engine from 1997–2016 Toyota GZ engine, a 5.0 L (305 cu in) DOHC design which was used in the Toyota Century limousine.
V12 is the Ferrari engine that using 65° V angle powered iconic cars as 456 M, 550 Maranello, 575 Maranello/ Superamerica, 612 Scaglietti, F50, Enzo Ferrari, 599, GTC4Lusso, F12berlinetta, LaFerrari, 812, Daytona SP3.
In China, the 2009 Hongqi HQE limousine, powered by a 6.0 L (366 cu in) DOHC V12 engine, is the sole Chinese car to be produced with a V12 engine
What is the 12 cylinder V-engine angle: many V12 engine use a V angle of 60 degrees between the two banks of cylinders. Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and secondary engine balance. By using the correct V-angle, a V12 engine can therefore have a perfect balance. The even firing order for a four-stroke V12 engine has an interval of 60 degrees, therefore a V12 engine can be perfectly balanced only if a V-angle of 60 degrees is used.
V12 engines with other V-angles have been produced, sometimes using split crankpins to reduce the unbalanced vibrations. The drawback of a V12 engine is the extra cost, complexity, and friction losses compared with engines containing fewer cylinders.
Smoothness: a V12 is inherently balanced and has more overlap between power strokes, making it a smoother engine layout than the V10. At any given time, three of the cylinders in a V12 engine are in their power stroke, which increases the smoothness of the power delivery by eliminating gaps between power pulses.
Racing use of 12 cylinder V-engine: use of V12 engines in motor racing is not the choice in recent years but was often used in the past in Formula One. The first V12 engine used in Formula One was in the 1964 Honda RA271 racing car and in 1966 V12 become popular, with new engines from Ferrari, Maserati, and Weslake. Ferrari's engine debuted in the Ferrari 312 racing car and was used up to the 1975 Ferrari 312B, after which Ferrari switched to a flat-twelve engine. Maserati's engine was introduced in the Cooper T81 and was used until the 1969 Cooper T86. BRM produced V12 engines from the 1968 BRM P133 racing car until the 1977 BRM P207. The Matra Sports V12 engine was introduced in the 1968 Matra MS11 racing car and used until the 1978 Ligier JS9. Few V12 engines in the following decade only Alfa Romeo V12 which was used by the 1979 Brabham BT48 and then by Alfa Romeo until the 1982 Alfa Romeo 182.
A new life of V12 in Formula One began in 1989, with the Ferrari 640 that used V12 until the 1995 when the 412 T2 became the last Formula One car to use V12. The Honda RA122-E engine was first used in the 1991 McLaren MP4/6 and was raced until the 1992 McLaren MP4/7A. The Yamaha OX99 engine was used in the 1990 Brabham BT59 through to the 1992 Brabham BT60. In prototype sports car racing, the highly successful 2006–2008 Audi R10 TDI used a diesel twin-turbo V12 engine. The Peugeot 908 HDi FAP, introduced in 2007, also used a diesel twin-turbo V12 engine.
