What should I do if the EGR valve of Guoliu gas vehicle freezes?

When the EGR valve is always closed, it will have an impact on automobile exhaust emissions, resulting in unqualified annual inspection waste emissions. EGR valve can reduce the temperature of the combustion chamber, improve the working efficiency of the engine, improve the combustion environment, reduce the burden of the engine, effectively reduce the emission of NO compounds, reduce knock and prolong the service life of parts by guiding the exhaust gas discharged from engine combustion to the intake manifold to participate in combustion.

Precautions:

Natural gas is abundant and cheap. The specific economic indicators must depend on the difference between the local supply price of natural gas or liquefied petroleum gas and the price of gasoline, taking liquefied petroleum gas as an example. Generally speaking, automobile users can save 65,438+00-65,438+05% of fuel costs, but for the investors of LPG filling stations, the total investment can be recovered in about 65,438+0 years. Promoting LPG vehicles is an investment behavior that can get returns, unlike simply adding exhaust gas purifier or EFI feedback control function, which increases consumption expenditure and purchase cost, and there is no recycling opportunity.

For gas suppliers, the application of gas in automobiles is equivalent to opening up a huge sales area. The amount of LPG in a bus is equivalent to 50-70 households. The former has low operating cost and high profit.
