The engine hydraulic energy and power conversion device is characterized in that an oil pan is fixedly arranged on a crank shaft box of a lower machine body, first and second pump bases are respectively fixedly arranged between an air cylinder body and the lower machine body, and the two pump bases are symmetrically arranged on the two sides of a machine body; a working piston, an upper connecting rod, a guide piston and a connecting rod are connected to form a piston connecting rod assembly, and the guide piston is articulated on a small head of the connecting rod; a large head of the connecting rod is connected with a crank pin of a crank shaft, first and second plunger pumps are fixedly arranged between the first and second pump bases, drivers of the two plunger pumps are articulated on a first forked lever pin shaft of the upper connecting rod so as to form a symmetrical drive structure, or, drivers of the two plunger pumps are articulated on the first and second fork rods on the different positions of the upper connecting rods so as to form an asymmetric driving structure; and the crank shaft is fixedly arranged in a crank shaft hole in the lower machine body. The engine hydraulic energy and power conversion device provided by the invention has the advantages that the structure is simple, a principle is reliable, the energy utilization efficient is high, the cost is saved, the power transmission is rapid, and the device is environment-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of internal combustion engine energy conversion, and relates to a structure for internal energy conversion of an engine, in particular to an engine hydraulic energy and power conversion device. Background technique: [0002] At present, for reciprocating engines, in order to improve the efficiency of power machinery, it is necessary not only to improve the effective efficiency of the engine, but also to tap the potential of improving the comprehensive efficiency of power machinery; the hydraulic free piston engine is a good example. But because the hydraulic free piston engine has problems such as unstable top dead center and poor ignition stability, it has been difficult to be popularized and used; although other similar types of engines can solve the problems existing in the free piston engine, they have poor power transmission reliability, mechanical How to comprehensively realize the high efficiency and...
