Abstract
The utility model discloses a gas engine post-treatment heat preservation device, and aims to provide a gas engine post-treatment heat preservation device capable of effectively guaranteeing temperature.
Description
Technical Field
The utility model relates to the field of automobile engine part equipment, in particular to a post-treatment heat preservation device for a gas engine.
Background
Natural Gas (CNG) is recognized as a technically mature fuel other than diesel, and natural gas engines have been popularized and applied in the world and China. Compared with gasoline and diesel oil, natural gas is a clean fuel, and has the advantages of less emission pollution, lower price and cost and better safety performance.
With the increase of the quantity of various global motor vehicles and the release of six national emission regulations, the establishment of six gas engine schemes is urgent. In view of the characteristics of natural gas, compared with the five-component aftertreatment of the country, the six countries increase the precious metal components of the catalyst, so that the oxidation reaction in the gas engine is more severe, and the exhaust emission temperature is further improved, so that the structure of the five original products cannot meet the requirement of the six countries on the surface temperature, and the heat insulation performance of the aftertreatment device needs to be further improved.
