Manual transmission might be almost dead in the USA – only 4 percent of all new cars sold there are equipped with stick-shift – but in the rest of the world it is still the choice of the majority. For ...

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.

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, ...

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 ...

British car maker Rover introduced its own VVT system called VVC (Variable Valve Control) on MGF in 1995. Many experts regarded it as the best VVT system at the time. The VVC can continuously vary the ...

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 ...

It would be good to have a linear, predictable steering response, but sometimes varying the steering ratio could enhance the driving experience. For example, when cruising on highway we want the ...

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 ...

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.

When I started watching cars in the mid-1980s, most cars on the road were still fed by carburettors, including the wildest supercars like Lamborghini Countach QV and Aston Martin Zagato. Carburettors ...

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 ...

Multi-valve engines started life in 1912 on a Peugeot GP racing car. It was then briefly used by the pre-war Bentley and Bugatti. However, mass production on road cars came as late as 1970s - Ford ...
