V-6 engine introduction
The V6 engine is a V-type engine with six cylinders. The six cylinders are divided into two rows, three in a row, and the two rows of cylinders are at an angle. This angle is generally about 60° or 90°, but there are also special ones. For example, Volkswagen's VR6 engine has an angle of 15°. . This type of engine is the second most common engine structure in modern cars, second only to inline four-cylinder engines.
The V6 engine is a compact engine construction that is shorter than an inline four-cylinder engine and more compact than the V8 in most designs. Because of this feature, the V6 engine is widely used in cars with front-wheel drive layouts. Because modern cars leave the engine smaller in size but require more horsepower, the more compact V6 engine is becoming more common.
The current intake-boost V6 engine provides more horsepower and torque than the naturally aspirated engine V8, while lowering fuel consumption and emissions. For example, Volkswagen's 3.0L turbocharged stratified injection V6 engine (TFSI) and Ford's turbocharged and direct fuel injection EcoBoost engines are comparable to Volkswagen's 4.2-liter naturally aspirated V8 engine.
The displacement of the current V6 engine is mostly between 2.5 and 4 liters, but there are some larger or smaller displacement V6 engines.
