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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

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, ...

In March 2005, the legendary John Z. DeLorean died at the age of 80. He will be remembered for two things: 1) He created the first modern muscle car, Pontiac GTO, when he was a senior executive at GM.

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 ...

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 ...

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 ...

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 ...
