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.

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 ...

Japanese cars of the late 1980s and 1990s were renowned for high technology. The most notable of them was Mitsubishi Galant VR-4. Introduced in 1987, this car packed the most technologies this side of ...

It was the best of times, it was the worst of times. Japanese motor industry rose to the peak in the late 1980s, just before the burst of bubble economy. Their rising ego drove them to build countless ...

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 ...

By the late 1960s, Fiat became the largest car maker in Europe and a formidable automotive empire. Its product range spanned from micro cars to large luxury saloons. It even offered as many as 4 lines ...

Combining cam-changing VVT and cam-phasing VVT may satisfy the requirement of both top-end power and flexibility throughout the whole rev range, though it is inevitably more complex. At the time of ...

The first time I heard about twin-scroll turbo was in 1989, when the updated Mazda RX-7 Mk2 introduced this feature. It was employed to seperate the exhaust gas from the Wankel engine's two rotors in ...

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 ...

Continuously Variable Transmission is getting more and more popular on small to mid-size cars, eating the market share of manual and low-end automatic transmissions. In 2015, the world produced 11.3 ...

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 ...

All cars need energy for propulsion. When they decelerate and stop, the energy is wasted in braking. Why not recapture the braking energy, store it and use it for acceleration later on? That is ...
