At the heart of an internal combustion engine lies a series of cylinders, cylindrical chambers that house the fiery combustion process. These cylinders, arranged in various configurations such as ...

Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...

Both gasoline-burning engines and diesel engines produce power through a process of internal combustion. However, the latter are usually larger, louder, and often dirtier. While many people may not ...

Last month's "How It Works" story gave you the basics of the four-stroke cycle, describing the motion of the intake and exhaust valves in relation to the piston moving up and down in the cylinder.

Intakes are vital automobile components that work to bring oxygen – a key ingredient in an internal combustion reaction – into the engine’s combustion chamber to modulate how much oxygen mixes with ...

In case you missed it, the automotive industry has been on a steady trajectory of internal combustion engine (ICE) downsizing for years. Battery-powered electric vehicles may capture most of the ...

As we begin the last article in this series on the basics of the internal combustion engine, let's stop to review what we've covered during the last five articles. We began last May by detailIing the ...

General Motors is well known for its small-block V8 engines; especially the powerful, reliable, and versatile LS series that debuted with the C5 Corvette in 1997. Unlike most of its rivals, GM decided ...

Turbocharger use is more prolific than ever, and understanding how one works explains why it's such a popular choice.

While diesel engines don't need spark plugs, they do need air ventilation for proper combustion. This is a problem for vessels traveling underwater, such as submarines. Yet diesel submarines exist and ...
