Cam-phasing VVT is the simplest, cheapest and most commonly used mechanism at this moment. However, its performance gain is also the least, very fair indeed. Basically, it varies the valve timing by ...

6 cylinder engines, no matter inline-6 or V6, are inherently smoother than 4-cylinder inline engines because all the first order and second order forces can be balanced. However, most small cars do ...

Steering is very important to a car because it is the interface that the driver touches most. What makes a car's steering better than another? It is usually judged by several factors: directness, ...

Clutchless manual cost just a fraction more than a conventional manual. It relieved driving effort, especially in traffic jam, making gearshift easier while having no disadvantages of automatic ...

As shown in the picture, straight-6 engine is simply a pair of 3-cylinder engines mated together symmetrically, thus piston 1 is always in the same position as piston 6, piston 2 the same as piston 5.

First introduced by Mercedes 300SL in 1954, tuned intake manifold is not exactly a new technology. It is discussed here just because its principle is useful to our further study of variable intake ...

A refined engine should be smooth running, free of vibration and quiet. These qualities also help the engine to spin freer at high rpm, lifting red line hence power output. Engine smoothness depends ...

The advantage of turbocharging is obvious - instead of wasting thermal energy through exhaust, we can make use of such energy to increase engine power. By directing exhaust gas to drive a turbine, ...
