ROTARY ENGINE

The Wankel engine is a rotary motor. At one time Peugeot used it in a production car and MAZDA still uses the Wankel in some of its models Here are various advantages:

• For gas control no valves and connecting rods are needed.
• Its weight is very low in comparison to a piston engine.
• Its volume is about half that of the piston engine with the same power.
• The production costs are lower compared to other motor types.
• It can reach higher revolutions per minute.

DESCRIPTION OF THE  4 CYCLES OF THE WANKEL ENGINE

     INTAKE                      COMPRESSION                    IGNITION                         EXHAUST

• After all consumption gases have been pressed out (see colour black and a) the intake cycle begins. Petrol air mixture flowes through the inlet channel into the blue chamber.The piston rotates to the left and compresses the fresh gas.
  Chamber a sucks in fresh gas, while chamber b starts to compress the gas. In chamber c the gas is completely burned and can flow out (see black colour).
• Chamber a sucks in petrol air mixture. Chamber b has compressed the gas completely. Now two ignition sparks ignite the compressed gas simultaneously. Chamber c presses out the burned gases.
• Chamber a is full of fresh gas. The compression cycle begins as soon as chamber a is closed. In chamber c the burned gases decompress and press the piston into spin direction. Meanwhile chamber c presses out burned gases.
