Modularized oil-saving type fuel engine with crossed and opposed cylinders

Abstract

The invention relates to a modularized oil-saving type fuel oil engine with crossed and opposed cylinders. The modularized oil-saving type fuel oil engine comprises combustion starting modules and a main transmission module, the main transmission module comprises a transmission case, a middle transmission crankshaft is rotatably mounted in the transmission case, and the combustion starting modules are mounted and connected to two sides of the main transmission module. The combustion engine module comprises air cylinders oppositely installed on the two sides of the transmission case, cylinder cavities of the air cylinders are oppositely arranged in a crossed mode corresponding to the middle transmission crankshaft, and air cylinder pistons are installed in the cylinder cavities of the air cylinders in a sliding mode and rotationally connected with the middle transmission crankshaft through connecting rods. The modular design is adopted, combined use of different power outputs can be achieved, maintenance and replacement of the fuel engine are more convenient, power increase, decrease and allocation are convenient, direct fuel efficiency can be improved to a certain degree, space can be better saved through the design of the crossed and opposed cylinder body mode, meanwhile, the length of a crankshaft is shortened, and power output is more efficient. The structure is suitable for gasoline and diesel fuel, and the universality is good.

Description

technical field [0001] The invention belongs to the technical field of fuel engines, and in particular relates to a modular intelligent control fuel-saving type cross opposed cylinder oil-gas secondary cycle turbocharged fuel engine. Background technique [0002] Most of the existing fuel engines are straight parallel-cylinder deflagration engines. For example, in-line four-cylinder is a common internal combustion engine. To be able to burn fully, engine designers have also thought of many ways to improve fuel combustion efficiency, but how to improve the direct fuel efficiency of internal combustion engines has always been the focus of research and development in the industry; moreover, the existing multi-parallel cylinders If there is a problem with one cylinder during the use of the engine, the entire engine will be affected because it is an alternate parallel structure. If it is overhauled, the entire cylinder needs to be disassembled and repaired, and maintenance is mor...

[0002] Most of the existing fuel engines are straight parallel-cylinder deflagration engines. For example, in-line four-cylinder is a common internal combustion engine. To be able to burn fully, engine designers have also thought of many ways to improve fuel combustion efficiency, but how to improve the direct fuel efficiency of internal combustion engines has always been the focus of research and development in the industry; moreover, the existing multi-parallel cylinders If there is a problem with one cylinder during the use of the engine, the entire engine will be affected because it is an alternate parallel structure. If it is overhauled, the entire cylinder needs to be disassembled and repaired, and maintenance is more troublesome; When the power is high, all cylinders still need to work, resulting in a large waste of energy
