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.

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 ...

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 ...

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 ...

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 ...

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 ...

Ram air intake is perhaps the simplest kind of forced induction. When the car is travelling at speed, air will be forced into the intake manifold through the ram air inlet which usually locates at the ...

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 ...
