Air-cooled diesel engine

Abstract

An air cooling diesel engine comprises two cylinders which are arrayed in V shape to the left and right parts. To the included angle of the two cylinders fix a camshaft for feed supply. One of the two supporting shaft neck to the ends of the camshaft is linked to the body bearing hole, the other one is linked to the crankcase cover bearing hole. To the left and right cylinders install one hydraulic pressure supporting column separately for camshaft air inlet and outlet. To the top of the included angle of the two cylinders installs a speed regulator and oil injector. To the body back installs a wind scooper. The engine is characterized of simple structure and prior performance, no need of water and light in weight. It is of stable performance and easy for maintaining. It can be applied to power generating set, lawn mover, garden machine, high speed and high pressure water pump, oil pump, boat engine.

Description

technical field [0001] The invention relates to an air-cooled diesel engine, which belongs to the technical field of power devices. Background technique [0002] Before the present invention is made, in the prior art, the traditional two-cylinder engine usually adopts the following structure: 1. Two cylinders are arranged in a line and vertically upward, and generally adopt water cooling. 2. The body is relatively complex. On the longitudinal section of the lower part of the body, three main bearings are arranged on the same axis. To assemble the crankshaft, piston, and connecting rod, each main bearing hole must be divided into a main bearing seat and a main bearing cover. , the joint surface of the seat and the cover, the positioning pin hole, and the fixing bolt hole must be finely machined; the three main bearing holes must be finely bored to ensure the coaxiality of the three holes. What is more troublesome is the front and rear end surfaces of the body And the bottom ...

2. The body is relatively complex. On the longitudinal section of the lower part of the body, three main bearings are arranged on the same axis. To assemble the crankshaft, piston, and connecting rod, each main bearing hole must be divided into a main bearing seat and a main bearing cover. , the joint surface of the seat and the cover, the positioning pin hole, and the fixing bolt hole must be finely machined; the three main bearing holes must be finely bored to ensure the coaxiality of the three holes. What is more troublesome is the front and rear end surfaces of the body And the bottom plane, the plane must be finely processed, the gear chamber is installed on the front surface, the gear chamber cover is installed on the gear chamber, and the flywheel cover is installed on the rear end surface. It is also necessary to ensure that the lower sealing surface of the gear chamber and the lower sealing surface of the flywheel cover are on the same plane as the bottom plane of the body. On the plane, install the oil pan on this bottom plane; in this way, the machine body has more finishing surfaces, m
