Description
Technical field
The utility model is about gas engine technical field, especially with regard to a kind of combustion gas filter.
Background technique
Mesohigh gas engine is generally used for the occasion that load changes greatly, such as: vehicle power supply, oil drilling etc.
Occasion, using mesohigh natural gas or gas component close to the gas source of natural gas, admission pressure generally in 400kPa or more, by
It is relatively high in gaseous-pressure, it is general using the air inlet scheme of single point injection or in-cylinder direct-jet after pressurization.To guarantee engine
Performance needs the steam supply valve group parts for meeting mesohigh gas burning system air inlet requirement before mesohigh gas engine, fires
Air cleaner is an essential components in steam supply valve group parts, to play the role of filtering combustion gas.
However, existing combustion gas filter has the drawback that 1, using threaded connection, installation is inconvenient, the phase of part
Position is difficult to ensure, is unfavorable for dismounting maintenance, and there are gas leakage hidden danger；2, the combustion that existing small gas engine uses
For the gas circulation internal diameter of air cleaner generally in 15mm or so, filter area is smaller, and combustion gas is by flow generally on the left side 100kg/h
The right side can not be suitable for the engine control system of demand gas flow 150kg/h.
The information disclosed in the background technology section is intended only to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition is already known to those of ordinary skill in the art existing
Technology.
