Problems solved by technology

[0009] 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

[0041] 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.

[0042] Definition of key components

[0043] BSG: (Belt Starter Generator) A belt starter generator system: it can realize engine start / stop function, energy recovery, auxiliary torque increase and other functions.

[0044] Electronic supercharger: (Electric Super-Charger ESC) 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 response of the engine, which can be within 0.25S To drag the speed of the motor to 70,000 rpm, air is needed to cool the motor, which is integrated inside the air filter.

Abstract

The invention relates to an engine cooling system improved structure comprising double expansion kettles. The engine cooling system improved structure comprises a high-temperature circulating cooling system and a low-temperature circulating cooling system, wherein the high-temperature circulating cooling system comprises one expansion water tank, a high-temperature radiator, an engine cooling water jacket, a first water pump, an electronic thermostat, an engine oil cooler, an electronic supercharger and a heater; the low-temperature circulating cooling system comprises another expansion water tank, a low-temperature radiator, a turbocharger, a second water pump, an intercooler and a BSG. According to the application, the two sets of circulating cooling systems are arranged, and the high-temperature radiator and the low-temperature radiator are arranged, so that the requirements of different components to be cooled for cooling temperature are effectively met; in addition, through the adoption of the technical scheme provided by the application, the size of the cooling system is not increased.

Description

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