In the race to field energy-efficient vehicles, don’t count out internal combustion technology just yet. GM recently debuted its homogeneous-charge-compression-ignition (HCCI) system in two drivable ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

What makes a diesel engine different to a regular gas engine, and is one better than the other?

The purpose of the ignition system is to ignite, or fire, the spark plugs in order to generate power to run the engine. To do so, the battery sends current to the ignition coil. Then that high voltage ...

The automotive ignition system is an incredibly amazing machine that has evolved for more than 100 years already and continues to evolve as the demand drives the need to develop more efficient engines ...

For the average beginner in the fine art of auto mechanics, and some old-timers as well, installing and wiring a stock eight-cylinder ignition distributor can sometimes be quite a chore, and when he ...

An ignition coil is a vital component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into the high voltage needed to produce sparks at the spark ...

The ignition is easily the most misunderstood system in any car. Most enthusiasts treat ignitions like some sort of weird, black magic/voodoo curse best left alone until it fails. Either that or they ...
