Converting the ignition of a fuel-air mixture into usable mechanical energy lies at the core of a dizzying number of internal combustion engines developed over the course of more than century.

Combustion efficiency in internal combustion engines refers to the proportion of chemical energy in the fuel that is converted into useful mechanical work. Attaining high combustion efficiency is ...

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" ...

When it comes to unconventional engine design, few exceed the Wankel rotary in terms of weirdness. Despite that, the same basic principles of internal combustion apply here: Fuel and air are mixed and ...

Reports of the death of the internal combustion engine have been exaggerated. Electric vehicles were once poised to diminish the ubiquity of traditional engines, but automakers are booking huge losses ...
