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.
Claims8
An engine, comprising:
- a cylinder system;
- a driving system disposed under said cylinder system and including a piston that is capable of moving upwardly and downwardly in said cylinder system and a crankshaft that is driven by said piston;
- a power generating system disposed on a side of said driving system and including a generator that is disposed on one end of said crankshaft and that is driven by said crankshaft, and a counterweight that is disposed on said crankshaft, said generator including a main body and a rotor that is pivotally disposed within said main body and that is adjacent to said counterweight;
- and
- a cooling system disposed on an opposite side of said driving system and including a first water pump that is in fluid communication with said cylinder system;
- wherein an outline of said rotor is projected along an axis of said crankshaft to form a first projecting zone, projected areas of said first water pump and said driving system along the axis of said crankshaft overlapping the first projecting zone;
- and
- wherein an outline of said main body of said generator is projected along the axis of said crankshaft to form a second projecting zone, said cooling system further including a second water pump that is in fluid communication with said generator, a projected area of said second water pump along the axis of said crankshaft being located in the second projecting zone.
