combustion engine
Featured
May 12, 2025
A combustion engine, or internal combustion engine, burns fuel inside a chamber to create power. Gasoline, diesel, or other fuel mixes with air, ignites via a spark plug or compression, and the resulting explosion pushes pistons that turn a crankshaft.
This mechanical motion drives wheels in cars, or propellers in boats and planes. The internal combustion engine revolutionized transportation in the 1800s and remains the dominant engine type today, though electric motors which don't burn fossil fuels and have many fewer moving parts are becoming increasingly common as alternatives.
