Today's article will focus on a rotary engine with reciprocating piston movement and a rotating crankcase. Since we are talking about a rotary engine with reciprocating piston movement, we will not discuss the Wankel engine, even though it belongs to the group of rotary engines, because its rotary piston revolves around an eccentric shaft.

We will, therefore, be interested in a completely different type of engine, which is a rotary engine, the pistons of which perform a reciprocating movement and whose crankcase rotates (rotates) together with the entire engine.

The Wankel rotary engine probably does not introduce, but in short, it is a type of combustion engine with a rotary piston that converts pressure into rotary motion. The four-stroke cycle takes place between the oval-shaped inner shell and the rotating piston, which is triangular.

The design of this engine has its advantages - the machine is compact, simpler to build (fewer moving parts), and can develop great power for its weight. Despite this, unlike Mazda, no other car manufacturer is dedicated to engine development.

A Wankel engine, sometimes called a rotary engine, is a type of internal combustion engine with a rotary piston that converts pressure into rotary motion. This type of engine brings many advantages.

Unlike a classic combustion engine, all parts of the Wankel engine rotate in one direction.
