Variable is good. From valve timing, valve lift, intake manifold, exhaust, ignition, fuel injection, turbocharging, cooling to lubrication, many things on today's engines can be variable. However, one ...

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, ...

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 ...

Ram Air Intake 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 ...

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 ...

Further Development Although Fiat and Ford involved CVT development early, it was the Japanese who made CVT popular. Subaru has been using CVTs on its mini cars since Justy and expanded to all its ...

To enable very lean air-fuel mixture without causing misfire, the GDI used concave-section pistons and very upright, tumble-generating intake ports. Together, they concentrate a richer fuel mixture at ...

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.
