Double crank shaft horizontal combustion motor with bidirectional piston cylinder

Abstract

The invention discloses a double crank shaft horizontal combustion engine with a bidirectional piston cylinder, which comprises an engine body (1), a starting device, a lubricating system, a fuel supply system, a cooling system, a plurality of cylinder bodies (2) and crank shafts (3), wherein two mutually symmetrical pistons (5) are arranged inside the cylinder body (2) and fixed on a piston rod (6), the piston rod (6) is fixed on a connecting rod (7) and can indirectly drive the crank shafts (3) to rotate, a combustion chamber (4) is positioned between the two pistons (5), and the combustion chamber (5) can simultaneously push the two pistons (3) to rotate when working. The invention reduces the fuel consumption by fully utilizing energy conversion power generated by the combustion of the fuel in the combustion engine, can be used as a petrol engine, a diesel engine or a combustible gas engine, has wide application range, and can simplify cylinder body units in a multi-cylinder combustion engine after a double-piston cylinder body is assembled, thereby reducing the volume, having simple structure and being easy to popularize.

Description

technical field [0001] The present invention relates to an internal combustion engine, more specifically a double crankshaft horizontal internal combustion engine with bidirectional piston cylinders. Background technique [0002] The transmission internal combustion engine seen at present, the general source of power is that the piston reciprocates in the cylinder, and works through mechanisms such as rocker arms and crankshafts. Since the existing internal combustion engine structure has a history of hundreds of years, its technology It is relatively mature and has high thermal efficiency, so it has been widely used. However, according to the analysis in its actual use, there are still some shortcomings in the internal combustion engine of the transmission structure. The traditional internal combustion engine is mainly divided into single-cylinder type and multi-cylinder type. The single-cylinder type internal combustion engine has relatively small power, so the application...

Problems solved by technology

However, according to the analysis in its actual use, there are still some shortcomings in the internal combustion engine of the transmission structure. The traditional internal combustion engine is mainly divided into single-cylinder type and multi-cylinder type. The single-cylinder type internal combustion engine has relatively small power, so the application The field is limited, and it is gradually replaced by the multi-cylinder internal combustion engine. The multi-cylinder internal combustion engine uses multiple cylinders to drive the crankshaft at the same time, and the power is relatively strong, so its application field is wide. It is transmitted in all directions at the same time, and there is only one piston and rocker arm in the cylinder, so that the energy generated by the combustion of fuel in the combustion chamber is not fully utilized, resulting in a waste of energy

[0003] For example, a flat internal combustion engine disclosed in the Chinese invention patent with the publication number CN1670345, a plurality of cylinders are arranged as a pair of cylinder block units symmetrical to each other, and the reciprocating motion of the piston in the cylinder block jointly drives the crankshaft to rotate. The internal combustion engine also adopts a curved neck communication structure, and the overall layout of the internal combustion engine is compact and relatively small in size, but the cylinder it uses is still a single cylinder and single piston, so it still does not solve the above-mentioned energy utilization generated by the combustion of fuel in the combustion chamber. The problem of insufficiency, especially in today's scarcity of non-renewable energy sources, how to maximize the use of energy generated by fuel combustion has become an urgent problem for various internal combustion engine manufacturers to solve
