Engine Capable of Reduing Noise

摘要

An engine includes an air cylinder system, a driving system including a piston and a crankshaft, a power generating system and a cooling system. The power generating system is disposed on a side of the driving system and includes a generator and a counterweight. The generator includes a main body and a rotor pivotally disposed within the main body. The cooling system is disposed on an opposite side of the driving system and includes a first water pump in fluid communication with the air cylinder system. An outline of the rotor is projected along the crankshaft to forma first projecting zone. Projections of the first water pump and the driving system along the crankshaft are located almost wholly in the first projecting zone.
