Abstract

The invention discloses a hydraulic control type opposed piston engine. In the scheme, each unit opposed piston component is provided with a group of opposed movable pistons, and interfaces at oil receiving ends of the pistons respectively correspond to interfaces of two groups of reciprocating positive displacement pumps on a rotating crankshaft. Changes in the rotating crankshaft and the positive displacement pumps are directly coupled onto the pistons to accurately control the movement direction of the pistons and the positions of upper dead center and lower dead center so as to respectively complete the working stroke of air intake, compression, acting expansion and expansion work and also the power output. The pistons can be controlled in a simple way to achieve the advantages of a conventional engine and a hydraulic free piston engine and overcome the defects of the conventional engine and the hydraulic free piston engine. A startup system, an oil supply system, a combustion system, a cooling system, a sealing system and other systems all adopt the existing completely mature techniques to facilitate the implementation of projects. The engine is suitable for promotion in the engine industry.

Description

technical field [0001] The present invention relates to an engine, in particular to a hydraulically controlled mobile opposed piston 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 the compression ratio can be achieved. Adjustment, energy saving and environmental protection and other technical indicators 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 cancel...
