The invention belongs to the technical field of internal
combustion engines, and relates to a double-power engine with an adjustable hydraulic and mechanical
power output ratio. A
piston is connected with a connecting rod through a
piston pin, the connecting rod is fixedly connected with a sliding block groove through a
fastener, a sliding block is embedded in the sliding block groove, the lower portion of the sliding block groove is provided with a
plunger and a guide rod, and the
plunger, the guide rod and the sliding block groove move synchronically. The guide rod is inserted into a guide hole in a pump support and guides movement of the
plunger. The connecting rod, the sliding block groove and the plunger move up and down in a reciprocating mode. A
crank pin is embedded in the sliding block, and the upper portion of a plunger sleeve and the upper portion of the pump support are provided with oil inlet holes in a communication mode. A plunger
stroke adjusting rack is parallel to a
crank and arranged on one side of a hydraulic
plunger pump. A rack support fixes the plunger
stroke adjusting rack on the pump support, and the plunger
stroke adjusting rack is meshed with a gear ring of the plunger sleeve. The double-power engine is simple in structure, reliable in principle, high in energy efficiency, cost-saving, fast in
power transmission and environment-friendly.
