Abstract

The invention relates to a high/low-temperature shunting engine cooling system. The system comprises a high-temperature circular cooling system and a low-temperature circular cooling system; and the high-temperature circular cooling system has three cooling liquid flowing ways of big circulation, small circulation and delayed circulation. In the big circulation and the small circulation, cooling liquid is shunted after passing through a cylinder cover water jacket; one part enters the cylinder body water jacket, and the other part enters warm wind; in the big circulation and the small circulation, an ultrahigh-temperature loop is included; and the high-temperature circular cooling system and the low-temperature circular cooling system respectively adopt single expansion water tanks. As the high-temperature circular cooling system is added with an electric control auxiliary water pump, the delayed circulation is realized, and the cooling liquid is shunted into the cylinder body water jacket and the warm wind after passing through the cylinder cover water jacket, the warming demands of all parts after engine stop can be preferably adapted to, and the circular cooling flowing direction problems among different parts are solved; and the single expansion water tanks are provided, so that the engine knocking probability can be reduced.

Description

technical field [0001] The invention belongs to the field of automobile cooling systems, and specifically refers to a high-low temperature split flow engine cooling system. Background technique [0002] Governments of various countries have promulgated more and more stringent standards for engine fuel consumption. For example, it is stipulated that automobile OEMs will continue to reduce fuel consumption to 5.0L / 100km in 2020; One technology is the supercharged miniaturization of the engine + hybrid technology. [0003] In response to local government regulations, a more innovative engine matching system must be found to accomplish this goal. Because on the premise of not losing power, it is basically an impossible task to reduce fuel consumption by 30% on the current basis. Therefore, it is proposed to use a hybrid power system + electronic supercharging on the engine, and achieve the requirement of reducing fuel consumption through weak mixing and miniaturization of engi...
