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

[0051] 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.

[0052] Definition of key components

[0053] BSG: (Belt Starter Generator) A belt starter generator system: it can realize engine start / stop function, energy recovery, auxiliary torque increase and other functions.

[0054] 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 responsiveness of the engine. The speed of the motor is dragged to 70,000 rpm, and air is needed to cool the motor, which is integrated inside the air filter.

Abstract

The invention relates to a dual-cycle cooling system for an engine. The dual-cycle cooling system comprises a high-temperature circulation cooling system, a low-temperature circulation cooling system and a delay circulation cooling system. The high-temperature circulation cooling system comprises a first expansion water tank, a high-temperature radiator, an engine cooling water jacket, a first water pump, an electronic thermostat, an engine oil cooling device, an electronic supercharger, a turbocharger and a heater. The low-temperature circulation cooling system comprises a second expansion water tank, a low-temperature radiator, a second water pump, an intercooler and a BSG. According to the dual-cycle cooling system, the three sets of circulation cooling systems are arranged, the high-temperature radiator and the low-temperature radiator are arranged, the requirements of different parts to be cooled for the cooling temperatures are met effectively, and the size of the cooling system is not increased by means of the technical scheme.

Description

technical field [0001] The invention belongs to the field of automobile cooling systems, in particular to an engine double-circulation 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 engine supercharging. Due...
