AI Technical Summary

Technical Problem

Range-extended commercial vehicles lack mechanical air compressors, resulting in high power consumption of the independent electric air compressors and continuous consumption of onboard electrical energy. Therefore, reducing the overall energy consumption of the air supply system has become an urgent problem to be solved.

Method used

Design a vehicle air supply system including an engine air supply passage and an auxiliary air supply passage connected by a bypass valve. The engine air supply passage provides compressed gas to the main air passage and low-pressure air-consuming equipment under high or medium load conditions. The auxiliary air supply passage stores and supplies compressed gas under low load conditions. It uses engine exhaust gas to drive a turbine for pressurization and stores and supplies high-pressure exhaust gas through the bypass valve when necessary.

Benefits of technology

By recycling engine exhaust gas, the reliance on independent electric air compressors is reduced, significantly lowering the overall energy consumption of the air supply system and achieving stable air supply without frequent starting of the electric air compressor.

Abstract

The application discloses a vehicle air supply system, a control method, equipment, a medium and a product, and relates to the technical field of vehicles.The vehicle air supply system comprises an engine air supply passage and an auxiliary air supply passage, the engine air supply passage and the auxiliary air supply passage are connected through a bypass valve, and the auxiliary air supply passage is connected with a main air passage of the vehicle and a low-pressure air-consuming device respectively.The engine air supply passage is used for supplying compressed gas to the main air passage and the low-pressure air-consuming device when the engine is in a high-load state or a medium-load state.The auxiliary air supply passage is used for supplying compressed gas to the main air passage and the low-pressure air-consuming device when the engine is in a low-load state.The application can recycle high-pressure exhaust gas generated by the engine, and thus the air supply system can complete air supply operation without starting the electric air compressor multiple times, thereby significantly reducing the overall energy consumption of the vehicle air supply system.
