... are, in many ways, better then piston engines, but their use is somewhat limited. Most rotary engines use only two rotors to generate power, which allows them to be smaller engines with less moving parts; lasting longer and remaining more efficient. Rotary engines are also very inexpensive ... the rotary engine can withstand driving under higher load and at higher RPM's thus having high top speed, and incredible horse power as well as overall power in the higher rpm's. Rotary engines are cost efficient to make and have tremendously more horsepower for far little displacement as compared ....

... the rotor moves around the chamber each of the three volumes alternately expands and contracts. The expansion and contraction draws air and fuel into the engine, compresses it and makes power as the gasses expand and then expels the exhaust. The rotary engine is an internal combustion engine, like the engine in a car, but it works in a completely different way then ... one happens in its own part of the housing. A few advantages of the rotary engine are that is is light weight and compact. It is smooth, and has and extended power stroke. There are also few moving parts, no valves, conne...
