General gasoline engine with tail gas treatment device

Abstract

The invention discloses a general gasoline engine with a tail gas treatment device, and relates to the technical field of gasoline engines. The general gasoline engine comprises a gasoline engine bodyand an oil storage tank fixedly arranged at the upper end of the gasoline engine body, wherein a silencer is fixedly arranged on the side, close to the oil storage tank, of the side face of the gasoline engine body, a filter tank is fixedly arranged at the gas outlet end of the silencer, a filter screen fixing frame is arranged inside the filter tank, and a filter screen is fixedly arranged on the inner side of the filter screen fixing frame. According to the general gasoline engine, large-particle impurities in waste gas exhausted by the silencer can be pre-filtered through the filter screen, the situation that the purification effect of the particle impurities is affected due to the fact that many large-particle impurities in the waste gas enter a particle catcher is effectively prevented, a spring is fixedly connected between a connecting rod and a fixing seat, and the filter screen fixing frame can be driven to shake up and down through working vibration of the gasoline engine body, so that the large-particle impurities attached to the filter screen are shaken off into a material collecting cavity of a sealing block, and the large-particle impurities in the material collectingcavity are convenient to clear.

Description

technical field [0001] The invention relates to the technical field of gasoline engines, in particular to a general-purpose gasoline engine with an exhaust gas treatment device. Background technique [0002] Engine (Engine) is a machine that can convert other forms of energy into mechanical energy. It was first born in the UK. It is not only suitable for power generation devices, but also refers to the entire machine including power devices (such as: gasoline engines, aero engines) The gasoline engine is an electric spark ignition internal combustion engine that uses gasoline as fuel. The gasoline engine generally adopts a reciprocating piston structure, and is composed of a body, a crank connecting rod mechanism, a gas distribution system, an oil supply system, a lubrication system and an ignition system. Lightweight, with the continuous and stable development of gasoline engine supporting hosts (automobiles, motorcycles, small power generation equipment, garden machinery, ...
