Mazda filed patents for a dual-spark-plug Skyactiv-X engine that enables more aggressive EGR and better lean combustion — a ...

Mazda may have found a way to keep its Skyactiv-X compression ignition system alive with a surprising two-plug twist.

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

Compression ignition engines rely on the rapid heating of air through piston-driven compression to initiate fuel autoignition, a process that underpins the performance and emissions characteristics of ...

We love ourselves a good oddball engine, and tiny, scrappy Mazda certainly must be responsible for more such engine concept patents per market-capitalization dollar than any other. We just discovered ...

Compression ignition basically is the term that is used for describing the manner in which diesel engines function. It happens when intake air—which often is combined with recirculating exhaust gas—is ...

Light-duty compression-ignition (CI) engines operating on diesel fuels have the highest thermodynamic cycle efficiency of all light-duty engine types. The CI diesel thermodynamic cycle efficiency ...

Modern compression ignition engines convert fuel energy into mechanical work by auto-igniting a compressed air–fuel mixture. Accurate modelling of in-cylinder processes is vital for both performance ...

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 ...

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...
