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 ...

Control of auto-ignition phasing in homogeneous charge compression ignition (HCCI) combustion has been achieved with a variety of methods that affect the thermodynamic state and the chemical ...

The morphing of state-of-the-art electronics into today's performance vehicles keeps getting better all the time. And in case you're confused as to what magazine you're reading, we're not referring to ...

It seems like such a small thing—that tiny area approximately 0.040 of an inch wide inside each combustion chamber. That area we're talking about is the gap between the electrode and strap on each ...

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 ...

As fuel prices continue to rise and consumer awareness and or government regulations for lower combustion emissions increase, automobile manufacturers are exploring ignition strategies to improve the ...

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 ...
