Every car engine has quite a few details, ranging from cylinder count to compression ratios. How does changing the compression ratio affect the engine?

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 ...

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.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 ...

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 ...

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 ...

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 ...

SAE Transactions, Vol. 105, Section 3: JOURNAL OF ENGINES (1996), pp. 1249-1259 (11 pages) The performance of an in-cylinder optical combustion intensity sensor is presented. The sensor and associated ...

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 ...
