The heat from burning a fuel produces power which moves the vehicle.Sometimes the engine is called the power plant. Automotive engines are internalcombustion(IC) engines because the fuel that runs them is burned internally, or inside the engine. There are two types: reciprocating and rotary (Fig. 112). Reciprocating means moving up and down, or back and forth. Most automotive engines are reciprocating. They have piston that move up and down, or reciprocate, in cylinder (Fig.113). These are piston engines. Rotary engines have rotors that spin, or rotate. The only such engine now used in automobiles is the Wankel engine (127).
