ABSTRACT The tradeoff between NOx emissions and combustion instability in an engine operating in the dual-fuel Reactivity Controlled Compression Ignition (RCCI) combustion mode was investigated using ...

The compression ratio isn't just a number: it's one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

For more than a century now, automotive engineers have struggled with an unavoidable balancing act when it comes to engine compression. Now, thanks to an innovation from Infiniti, they may get to ...

As Mazda and Infiniti have proved, there's a lot of innovation left in the internal-combustion engine. One of the more wild concepts we've seen is called Reactivity Controlled Compression Ignition ...

Why compression ratio suddenly matters so much On paper, compression ratio is a simple concept, the comparison between a cylinder’s maximum and minimum volume as the piston travels from bottom to top ...
