The recycling of heat, ensure that engine is operated in optimum temperature range under different operating modes.Again because engine is low
Quickly it can heat and start under temperature state so that the temperature of engine inner engine oil rises rapidly, so as to reduce engine oil viscosity, subtracts
The mechanical friction loss of engine under few low-temperature condition, and then reduce consumption and reduce the purpose of the discharge of pollutant, but
That the recycling of heat of engine is reached warming-up effect by this invention, this method especially at low temperatures, warming-up
DeGrain, cause oil temperature too low, its viscosity will increase, and circulation is deteriorated, machine oil following in lubricating system
Ring is slack-off, causes the frictional resistance of mechanical part to increase, and makes the rotating speed that needs are unable to reach in the engine short time, or even have can
Energy engine start failure, and it is insufficient in warming-up process, and engine load is big, performance and service life production to engine
Raw very big influence.Meanwhile gasoline combustion is insufficient, the content of the pernicious gas such as CO and NO compounds is higher in tail gas, adds
PM2.5 discharge, is unfavorable for environmental protection.
