Problems solved by technology

[0010] The purpose of the present invention is to propose an improved technical solution to the existing engine cooling system. Through this technical solution, the flow direction of the coolant circulation between different components can be better adapted to solve the problems of intercooler, BSG, electronic supercharger, turbine, etc. The cooling problem of the supercharger and the oil cooler can solve the high heat dissipation demand of the BSG at low engine speed and the delayed cooling function after the turbocharger is shut down

Embodiment Construction

[0052] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.

[0053] Definition of key components

[0054] BSG: (BeltStarterGenerator) a belt starter generator system: it can realize the engine start / stop function, realize energy recovery, auxiliary torque increase and other functions.

[0055] Electronic Supercharger: (ElectricSuper-ChargerESC) is an electronic matching product that can improve the ignition and combustion state of the automobile engine. Its main function is to improve the low-end torque and torque responsiveness of the engine. The speed is dragged to 70,000 rpm, and air is needed to cool the motor, which is integrated inside the air filter.

[0056] Electronic water pump: A mot...

Abstract

The invention relates to an engine cooling system including double expansion tanks. The engine cooling system includes a high-temperature cycle cooling system, a low-temperature cycle cooling system and a delayed cycle cooling system, wherein the high-temperature cycle cooling system comprises a first expansion tank, a high-temperature radiator, an engine cooling water jacket, a first water pump, an electronic thermostat, an engine oil cooler, a turbocharger and a heater; the low-temperature cycle cooling system comprises a second expansion tank, a low-temperature radiator, a second water pump, an electronic turbocharger, an intercooler and a BSG. According to the application of the invention, the two sets of cycle cooling systems are arranged, and the high-temperature radiator and the low-temperature radiator are arranged in the systems respectively, so that the requirements of different to-be-cooled parts for the cooling temperature are ensured; in addition, the technical scheme of the application does not increase the size of the cooling system.

Description

technical field [0001] The invention belongs to the field of automobile cooling systems, and specifically refers to an engine cooling system including double expansion tanks. 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 en...
