Abstract
An engine includes a 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 cylinder system. An outline of the rotor is projected along the crankshaft to form a first projecting zone. Projections of the first water pump and the driving system along the crankshaft overlap the first projecting zone.
