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 ...

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 ...

The ignition system’s job is to ignite the air-fuel mixture in a gasoline engine. In addition to the spark plugs that spark in the combustion chambers, the ignition system consists of an ignition coil ...

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 ...

Ignition system technology has taken a number of twists and turns over the past 50 years. Matthew Beecham talks with experts from Delphi and Denso about the latest developments both on the OE and ...

When it comes to ignition, plug wires are often the Rodney Dangerfields of the system. This is a misconception because while not the glamour boys of automotive electronics, spark plug wires play a key ...

Myth 1:A Voltmeter Is BestReality:A Scope Is Much BetterThe reason ignition systems are so hard to understand is because the flow of electricity cannot be seen. A common voltmeter used by many to ...

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 ...
