Description
Technical field
The present invention relates to a kind of jacket structure of gas cylinder cover, belong to machining apparatus technical field, and in particular to one kind can change
It is apt to the jacket structure of gas cylinder cover of engine cold starting performance and the engine-cooling system containing the structure.
Background technique
For petrol engine in cold start, in cylinder and oil temperature is lower, and fuel atomization effect is poor, to guarantee dynamic property
Enriching need to be carried out to gaseous mixture, mixture combustion is insufficient at this time, will lead to oil consumption rising and HC, CO discharge increase, be degrading
The fuel economy and emission performance of engine；In addition, the state that machine oil is in solidification or is precipitated due to low temperature when cold start, profit
Slip can decline, and will lead to the movement parts abrasion aggravation of engine, influence the reliability started.
To reduce the adverse effect generated when above-mentioned cold start, large and small circulation can be arranged in general engine-cooling system
Pipeline.When engine cold starting, thermostat is closed, and coolant liquid, without passing through radiator fan, can be mentioned quickly by partial circulating pipeline
Coolant temperature is risen, coolant liquid is divided into two after flowing through partial circulating pipeline heating: being connected to engine body all the way, is connected to machine all the way
Oil cooler, flows into that in-engine coolant rate is bigger, the time is longer, then can more improve the warming-up speed and just of engine
Often operation, is effectively improved the discharge and oil consumption performance in engine cold starting stage, reduces the abrasion of engine.
In a kind of engine cooling system structure of Chinese utility model patent CN202100318U, more particularly to a kind of hair
