The Wankel Engine
The Wankel engine is a type of internal combustion engine that is different than any other design. Even though it is much less common than the everyday gasoline engine, it is a much more practical design. It has proven to achieve higher horse power ratings while also having better efficiency than other gasoline engines of similar displacement.
The Wankel Engine’s efficiency comes from the design where instead of having multiple pistons doing one of the four strokes of a four stroke engine (intake, compression, combustion, exhaust) at a time, it has a single triangular shaped rotor doing all four at once. And because the rotor rotates in a circular pattern there in no stopping to change the direction of the rotor unlike pistons which have to change directions with every stroke, this also makes the Wankel Engine smoother and better balanced than traditional internal combustion engines. And also because there is usually only one or two rotors, depending on the engine, they are much more compact than the traditional inline or v-block designs.
How this marvel of engineering works is the rotor rides on an offset in the crankshaft, similar to a piston nand connecting rod assembly, and is rotated in an oval shaped case with ports for intake, exhaust and spark plugs. Incorporated into the rotor is a ring gear which had another gear that is stationary in the center, this planetary gear set is what keeps the rotor in time with the rest of the engine. The rotor creates three sealed areas where the different strokes will take place simultaneously, these three areas are sealed by strip of metal called the Apex seal which have the same function as the piston rings in a traditional internal combustion engine. The intake and ...

...agner, a local Nazi party leader, Felix Wankel was arrested and imprisoned in 1933 when the Nazi party took control of Germany. But soon after he was pardoned by Wilhelm Keppler who was an old friend of Wankel’s and also Adolf Hitler’s lead economic advisor. With the help of Wilhelm Keppler, Wankel was given funding’s for his own workshop and research center in Lindau to design and produce rotary valves and seals for the German Air Force’s aircraft and the German Navy’s torpedos, but all this ended with the war. In 1957 Felix Wankel produced the first working model of the Wankel Engine, only producing 21 horsepower it was still a great achievement.
And then in 1960 he was able to produce and start selling the first practical Wankel Engine, the KKM 250, which was used in the NSU Spider car. Felix Wankel died on October 8th 1988 in Heidelberg Germany at the age of 86.
