Single mode four-stroke minitype water-cooling oil gas electricity generating engine

Abstract

The invention discloses a single mode four-stroke minitype water-cooing oil gas electricity generating engine, and relates to the technical field of engines. A piston arranged in an air cylinder is connected to a bent shaft through a connecting rod, reciprocating motion of the piston is converted to rotational motion through the bent shaft, the two ends of the bent axle are connected to electric generators, the left end of a combustion chamber is provided with an air suction opening and an air suction valve which switches on and off the air suction opening, the right end of the combustion chamber is provided with an air exhaust and an air exhaust valve which switches on and off the air exhaust, a communicating path which communicates a rocker arm chamber inside a bent shaft chamber and a rocker arm chamber inside a cylinder head lid is formed between a cylinder head and a cylinder body, pushing rods and tappet rods are inserted in the two sides of the communicating path, the front end parts of the tappet rods abut against air suction cams of cam shafts and exhaust cams of the cam shafts in the bend shaft chamber, the other ends of the pushing rods abut against rock arms arranged in the rock arm chamber, and the rock arms are connected to the air suction valve and the air exhaust valve through valve springs. The single mode four-stroke minitype water-cooling oil gas electricity generating engine is low in oil consumption and gas consumption, low in noise, light in weight and small in size, can inhibit the increase of a starting torque when being started and inhibit explosion inside a noise deader no matter a geometry compression ratio is high or low.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a four-stroke water-cooled oil-gas dual-purpose power generation engine capable of suppressing the increase of starting torque at startup even if the geometric compression ratio is high or low, and suppressing explosion in the muffler. Background technique [0002] At present, four-stroke miniature water-cooled oil-gas power generation engines have been widely used in various equipment, for example; pure electric vehicles are used in mobile charging devices, vehicle-mounted power generation equipment, and power generation equipment in mountainous areas and islands. Generally, in order to improve the thermal efficiency of the engine, improve The compression ratio (expansion ratio) in the combustion chamber is effective, but if the compression ratio is increased, the pressure during compression will increase, so the starting torque when the engine starts increases. In some cases, i...

[0002] At present, four-stroke miniature water-cooled oil-gas power generation engines have been widely used in various equipment, for example; pure electric vehicles are used in mobile charging devices, vehicle-mounted power generation equipment, and power generation equipment in mountainous areas and islands. Generally, in order to improve the thermal efficiency of the engine, improve The compression ratio (expansion ratio) in the combustion chamber is effective, but if the compression ratio is increased, the pressure during compression will increase, so the starting torque when the engine starts increases. In some cases, if the torque is large when starting, the operator needs more force, and a decompression device must be installed. Based on this, it is still necessary to design a new type of single-mode four-stroke micro-water-cooled oil-gas power generation engine
