News that Mazda is hoping for a 30% fuel efficiency gain on an HCCI (Homogeneous Charge Compression Ignition) engine to be introduced on the next generation Mazda3 in late 2018 brings this technology ...

General Motors Corp. today unveiled a new engine it that it says will increase fuel economy by 15 percent by burning gasoline the same way a diesel engine burns fuel. GM calls the innovation ...

Researchers at all the major car companies and U.S. labs are trying to perfect homogenous-charge compressionignition technology (HCCI) in the quest for more fuel-efficient internal combustion engines.

It is a technology that melds a diesel engine's high efficiency and massive torque with a gasoline engine's low emissions and smooth running. And it could be the next big evolution of the internal ...

The automotive industry continues to be a hotbed of innovation, with activity driven by factors such as auto-ignition properties of the fuel, fuel concentration, and residual rate, and growing ...

It's a technology that's been a sort of Holy Grail in the auto industry for at least a couple of decades. Now Mazda, one of the smallest global automakers, plans to introduce it in a radical new ...

What many consider the Holy Grail of combustion technology is one step closer to prime time. In the race to field energy-efficient vehicles, don’t count out internal combustion technology just yet. GM ...

Well, at this year's Hyundai powertrain-tech shindig, I got an update from powertrain honcho John Juriga as to just whatever happened to GDCI. He explained that under compression-ignition operating ...

Electric powertrains are important, but combustion engines should come first. That message came today from Mazda R&D head Kiyoshi Fujiwara as his company announced that it had developed the world’s ...

SAE Transactions, Vol. 112, Section 3: JOURNAL OF ENGINES (2003), pp. 1500-1510 (11 pages) This study considers combustion processes in a heavy-duty diesel engine at various low emissions operating ...
