The cylinder cover stores a cooling liquid. The warming time of the engine is remarkably shortened compared with that of the prior art. The engine is fast to pre-heat, so that on the one hand, warm air quickly heats the driver's cab to improve the comfort level of a passenger, and on the other hand, the oil consumption of the engine is favorably reduced.
Description
Technical field
The present invention relates to automobile technical field, more particularly to a kind of engine-cooling system and the car with it
.
Background technology
Automobile has become the irreplaceable vehicles in people's daily life, and the effect of cooling system is full
The demand of sufficient automobile cooling performance, the especially temperature control needs of engine, realize rapid warming-up and in time
Cooling, it is ensured that engine works within the temperature range of requiring.But, current cooling system exists following
Some problem：
(1) coolant of the cylinder body of available engine and cylinder cap can only all be provided by cylinder body, therefore, it is right
When cylinder cap is cooled down, the coolant in warm-up period cylinder body must also be circulated, and this just extends
Warm-up period, runs counter to the design requirement of Modern Engine rapid warming-up, and be unfavorable for the quick of warm wind plus
Heat.
(2) mechanical water pump is used in existing cooling system, as long as the shortcoming of mechanical water pump is
Engine works, and water pump just in operating, i.e., locate always by all parts in gray iron and cooling system
In the state of cooling, and warm-up period cylinder body need not carry out forcing cooling, and this can cause engine extra
Oil consumption is lost, and reduces warming-up speed.
(3) in existing cooling system, oil cooler is connected with cooler for recycled exhaust gas or warm wind, is attempted by micro-
In circulation (cylinder cap circulation).Oil cooler is supplied water by cylinder cap, it means that since warm-up period,
Oil cooler begins to cooling, and this can increase pipeline internal resistance in microcirculation, pump load is increased and then is prolonged
Warm-up period long, is unfavorable for rapid warming-up.
Thus, it is desirable to have a kind of technical scheme come overcome or at least mitigate prior art at least one it is above-mentioned lack
Fall into.
