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.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

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 ...

LONDON--(BUSINESS WIRE)--Technavio market research analysts forecast the global automotive homogeneous charge compression ignition (HCCI) market to grow at a CAGR of more than 17% during the forecast ...

ABSTRACT The operating range in HCCI mode is limited by the excessive pressure rise rate and therefore high combustion induced noise. The HCCI range can be extended with turbocharging which enables ...

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 ...
