As we've mentioned, Mazda is no stranger to developing unconventional engineering solutions that other carmakers would ever ...

A compression-ignition engine's near simultaneous combustion tends to burn the intake charge more completely and at lower combustion temperatures (1,200 degrees F anticipated), virtually ...

Mazda’s powertrain team has brewed up a fancy new engine that, like a diesel, uses compression to activate the combustion process. In a press release on the new tech, Mazda tells us just how ...

GlobalData uncovers the leading innovators in homogenous charge compression ignition engines for the automotive industry.

Mazda has detailed the next-generation of its SkyActiv engine family, which will feature innovative compression ignition technology.While the new SkyActiv engine is still under development, Mazda ...

Infiniti has a variable compression ratio engine, but Mazda has a different solution. It's set to release the first commercial compression-ignition gasoline engine, dubbed SkyActiv-X.

Unlike some other automakers’ previous attempts at gasoline-burning compression ignition, Hyundai will not fit the engine with any spark- or glow plugs.

Most pickup trucks sold today have internal combustion engines. Passenger vehicles are powered by two main types of engines: compression, aka diesel, and spark ignition, aka gasoline. Besides the ...

HCCI engines have a compression ratio of 12:1 (similar to that of a conventional direct-injected gas engine), so they can run on regular pump gas and E85.

Spark Controlled Compression Ignition, as Mazda calls its proprietary system, works because it behaves more like a traditional gasoline engine despite the diesel-like technology and having a ...

Homogeneous charge compression ignition (HCCI) engines combine a diesel's torque and fuel efficiency with a gas engine's cleaner emissions. The HCCI technique has been a goal of automakers since ...
