Abstract

The present application provides an engine thermal management system and a vehicle, the system includes an engine, a waste heat exchanger, an electric control valve and a water pump, and the electric control valve communicates with the engine, the water pump and the waste heat heat exchanger respectively , the engine communicates with the water pump and the waste heat exchanger respectively; the engine is provided with a cylinder water jacket and a cylinder head water jacket, and the cylinder head water jacket is arranged in parallel with the cylinder body water jacket, The cylinder body water jacket is arranged in series with the waste heat exchanger; the electric control valve is used to control the distribution of fluid flow in the cylinder body water jacket and the cylinder head water jacket. The application can fully consider the precise temperature requirements of the cylinder block and cylinder head, and realize the special requirements of the cylinder body for temperature rise and high temperature, thereby reducing fuel consumption and emission.

Description

technical field [0001] The application belongs to the technical field of automobile engines, and in particular relates to an engine thermal management system and a vehicle. Background technique [0002] With the increasingly stringent fuel consumption and emission regulations in the global automotive industry, the fuel consumption per 100 kilometers needs to be reduced to 4L in 2025, and the fuel consumption target per 100 kilometers in 2030 is 3.2L. Therefore, electrification and intelligence are the inevitable trend of automobile development. However, pure electric vehicles face the problems of charging anxiety caused by the cost of battery packs, high vehicle prices, lack of basic charging facilities, and user mileage anxiety. Major international OEMs agree that the hybrid model will be the main development direction of the automotive industry for some time to come. The hybrid thermal management system has a greater impact on the fuel consumption and emissions of the veh...
