Abstract

The invention discloses a double-cylinder four-piston opposed hydraulic control engine. Two groups of opposed piston components are respectively provided with a group of opposed moving pistons; and joints at oil-receiving ends of the pistons correspond to those of two groups of reciprocating volume pumps on a rotating main shaft respectively. The main shaft is rotated, then the volume pump is changed to be directly coupled on the piston, and the moving direction and the positions of the inner dead point and the outer dead point of the pistons are controlled accurately so as to respectively finish the working stroke of gas inlet, compression, working expansion and exhaust, and power output. In the double-cylinder four-piston opposed hydraulic control engine, the pistons are controlled by asimple mode so as to give consideration to the advantages of the conventional engine and the hydraulic free-piston engine, and also avoid the respective defects. Other systems such as a starting system, an oil supply system, a combustion system, a cooling system and a sealing system share the existing fully-mature technology so as to be convenient for implementation of the project. The double-cylinder four-piston opposed hydraulic control engine is applicable to promotion of the engine industry.

Description

technical field [0001] The invention relates to an engine, in particular to a twin-cylinder four-piston opposed hydraulic control engine. Background technique [0002] Existing conventional engines rely on the crankshaft, piston, connecting rod, and cam valve mechanism to complete the engine's working process. It is now very perfect, but it has reached a certain working condition, such as large cylinder diameter, long stroke, high boost and high power, and compression ratio. Reconciling technical indicators such as energy saving and environmental protection will be restricted by various aspects. In this field, people have made various attempts, including the famous triangular piston rotary engine, but because of its special curve, it has caused difficulties in production and maintenance, especially the sealing has not been fundamentally solved. So it has not been widely promoted so far. [0003] Can the engine structure be simplified such as canceling the crankshaft, conne...
