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 ...

In the interest of making sure we all know they've got a mapped strategy for powertrain technology, GM is taking its message on the road. Recently, we got the chance to talk to a few of GM's experts ...

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 ...

Here in 2019, only the most fringe reactionaries are able to claim with a straight face that climate change is not a thing. But after years of the media doing its “two sides” thing, recalcitrant ...

A German startup is developing a potential replacement for spark plugs: microwave pulse ignition. The tech is under development by MWI Micro Wave Ignition AG of Empfingen, Germany, which claims that ...

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 ...

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 ...

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 ...

No Ford engine project is complete without a properly functioning ignition system. This system has the important job of delivering the spark to the required cylinder at precisely the right time. Any ...
