Internal combustion engines have largely been eclipsed by advanced propulsion systems such as jet turbines, electric drives and hybrid technologies. Yet their role in military history remains ...

The film discusses various types of engines that utilize heat energy for operation. It explains steam engines, which are reciprocating external combustion engines, and compares them to internal ...

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

Almost all gasoline engines, whether they're efficient-yet-less-refined four-cylinders, high-horsepower V6s, or growly and torque-rich V8s, use much the same process to create power. The "Otto cycle" ...

In an internal combustion engine, air and fuel are injected into the cylinders, where ignitions occur in a controlled environment. The combustion cycles force pistons to move, and that movement is ...

What makes a diesel engine different to a regular gas engine, and is one better than the other?

Westport Fuel Systems said its H2 HDPI fuel system burns hydrogen in a modified internal combustion engine with almost no carbon emissions and performance superior to that of the base diesel engine.

Automotive engineers have invested countless billions trying to improve upon the humble internal combustion engine, but not all those efforts have translated well. In fact, sometimes, things got weird ...

GM Powertrain engineer John Rydzewski explains many of the features in the 2014 LT1 Corvette engine, including direct injection, continuous variable valve control, the rotating assembly, engine block, ...
