IRVINE, Calif.—Despite rumors to the contrary, the internal combustion engine is far from dead. Recently we’ve seen several technological advances that will significantly boost the efficiency of ...

The Advance CurveAll engines require an ignition curve based both on the requirements of engine rpm and cylinder filling (volumetric efficiency). This means that at 3,000 rpm with the throttle open ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...

A new modelling approach for premixed turbulent combustion has been developed and implemented in computing flow and combustion in axisymmetric engine cylinders. Turbulent transport is treated using 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 the ...

Could diesel particulate filter (DPF) regenerations become a thing of the past? A Southern California startup that is gaining the attention of OEMs believes it’s possible. For the past few years in ...

Engine knocking can be an annoying issue to deal with, and it can even cause damage to your car. Here's why it might happen, and how you can prevent it.

Even today, in a time when electric power is beginning to take a major hold, internal combustion engines (ICE) are the driving forces of our world. They probably won't be that for long, though, so ...

V-shaped engines like the V6 and V8 power lots of cars, but you probably never think about what, exactly, that V angle is. That's okay. Automotive engineers do.
