Title:
CONTROL METHOD AND SYSTEM FOR CHARGE AIR INTERCOOLER OF ENGINE
Document Type and Number:
WIPO Patent Application WO/2023/221581
Kind Code:
A1
Abstract:
A control method for a charge air intercooler of an engine. The charge air intercooler comprises a primary thermal management unit (3) which can heat and cool charge air. The control method for a charge air intercooler comprises the following steps: obtaining real-time charge air temperature at an air inlet (1) of a charge air intercooler; if the real-time charge air temperature is less than a lowest temperature limit value, controlling a primary thermal management unit (3) to start a heating mode; and if the real-time charge air temperature is greater than a maximum temperature limit value, controlling the primary thermal management unit (3) to start a refrigeration mode. According to the control method, the charge air temperature in a cylinder of an engine can reach the optimal temperature, thereby improving the reliability of a cylinder head, an exhaust valve, and an exhaust pipe of the engine. Also provided is a control system for a charge air intercooler of an engine.
