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 ...

Will joined the TopSpeed team over two and a half years ago, bringing his lifelong automotive passion, writing experience, and editorial expertise along with him. Whether classic or modern, American ...

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 ...

Does your Ford small-block need a potent ignition system? Performance Distributors Street/Strip DUI is an easy upgrade for 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 ...

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 ...

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 ...

Under the necessary conditions of ignition and proper burn rates (cylinder pressure history), both these conditions can exist in virtually any engine. But, in particular, they certainly apply to race ...

There is no shortage of people around the world today who seem pretty certain that the days of the internal combustion engine (ICE) as the primary form of propulsion for transportation are effectively ...
