Internal combustion engines typically have low efficiency, with modern gasoline engines around 35% and diesel engines ...

"No replacement for displacement" was the motto that produced some large powerplants during the exciting muscle car era. Nevertheless, this motto was taken to another dimension in the case of these ...

For hundreds of years of human history, the invention that has defined our ability to travel, explore, and expand our boundaries has been the combustion engine. This hallmark of mechanical development ...

When we here in the modern age think of an “engine,” we are usually thinking of a four-stroke, four-cylinder, gasoline-fed, internal-combustion engine with the valves on the top. But why must that be ...

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 ...

When I went to school for engine repair in the 1980s, we studied the differences between two- and four-stroke engine cycles extensively. If you're not familiar with engine strokes, understanding the ...

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 ...

Heat transfer in internal combustion engines governs both performance and durability by controlling temperatures within the combustion chamber, cylinder walls, piston crown and cylinder head.
