When the cooling system with the structure is adopted to cool the engine, the engine body 7 and the cylinder cover 6 can be cooled specially, and cooling water in different cooling channels can absorb heat in the engine body 7 or the cylinder cover 6 more fully, so that the cooling effect on the engine is improved. And the cooling performance of the cooling system can be effectively improved by arranging the degassing structure.
As shown in fig. 1, in the present embodiment, an electrically controlled ball valve 5 is preferably disposed on the water outlet of the water pump 4, and the electrically controlled ball valve 5 changes the opening degree under the control of an electronic control unit (i.e., ECU) of the engine. In the working process of the engine, the engine body 7 and the cylinder cover 6 have different temperatures, so that cooling water flowing out of the water pump 4 needs to be reasonably distributed according to different temperatures, namely, the cooling water flow entering the engine body cooling channel 13 and the cylinder cover cooling channel respectively needs to be controlled, so that the engine body 7 and the cylinder cover 6 are cooled in a targeted manner, the electric control ball valve 5 is arranged on a water outlet of the water pump 4, the area proportion of two water outlets (the two water outlets refer to two ports corresponding to a water inlet of the engine body 7 and a water inlet of the cylinder cover 6 respectively) can be accurately controlled through real-time control of the electric control ball valve 5 through an ECU, and the distribution control of the water flow in two ways is realized. The air cylinder can be limited from radiating outwards when the engine is in cold start, the heat efficiency of the engine is improved, the oil consumption is reduced, and the cold start time is shortened. Body 7 and cylinder cover 6
More preferably, the area of the water inlet of the machine body 7 is different from the area of the water inlet of the cylinder cover 6, and the distribution proportion of the cooling water in the machine body cooling channel 13 and the cylinder cover cooling channel can be more accurately controlled by controlling the area proportion of the water inlet of the machine body 7 and the area proportion of the water inlet of the cylinder cover 6 and matching the electric control ball valve 5 with the water inlet of the cylinder cover.

So set up, can make each jar spill gas alone, each jar gas effect is even, avoids the poor and local hot problem of the gas homogeneity of each jar spilling, can also make the gas effect of spilling of each jar organism 7 strengthen simultaneously, effectively improves the cooling performance of system.
Preferably, the spill air passages 12 are pre-cast passages that are pre-cast in the cylinder head 6, and different portions of the pre-cast passages are each enclosed outside the bore of different cylinders, as shown in fig. 4. The gas overflow channel 12 is a precast channel, so that the machining area of the cylinder cover 6 can be reduced, and the machining difficulty of the cylinder cover 6 is effectively reduced. And make the different parts of precast passageway surround respectively in the cylinder hole outside of different cylinders, then can be more reasonable utilize the free space of cylinder cap 6, reduce the influence that other structures caused on cylinder cap 6.
Further, in the cooling system provided in the present embodiment, as shown in fig. 1, a thermostat 8 is further disposed on the cooling circuit where the cylinder head 6 is located, and the thermostat 8 is not disposed on the cooling circuit where the engine block 7 is located.
