Star-shaped or radial engine - piston internal combustion engine, the cylinders which are radial rays around a crank shaft through equal angles. Radial engine has a small length and allows compact place a large number of cylinders. Has found wide application in aviation.

The main difference between radial engine from piston engines of other types is in the construction of a crank mechanism. One rod is a major (he looks like a normal crank the engine in-line cylinders), the others are trailing and attached to the main connecting rod on its periphery (the same principle applies to the V-twin engine). Radial engine design flaw is the possibility of leakage of oil into the lower cylinders while parked in connection with what is required before starting the engine to verify the absence of oil in the lower cylinders. Starting the engine in the presence of oil in the lower cylinder leads to water hammer and damage to the crank mechanism.

Depending on the size and power of the engine radial engine can be due to lengthening the crankshaft to form a few stars - the series.

Four-star-engines have an odd number of cylinders in a row - it allows to provide a spark to the cylinders "by one ".
