Abstract

The invention provides an engine thermal management system and method.The system comprises a thermal management valve and an electric control bypass valve, the thermal management valve is connected with a first exhaust manifold of an engine, and the electric control bypass valve is connected with a second exhaust manifold of the engine; the thermal management system further comprises an exhaust back pressure valve, and the exhaust back pressure valve is connected with the vortex end. Combustion waste gas of the engine is used for providing energy for the gas compressor through acting of a turbine of the turbocharger; and in combination with a fed-back turbine front pressure signal, closed-loop regulation of turbine efficiency is realized through combined regulation and control of a designed thermal management valve, an electric control bypass valve and an exhaust back pressure valve. Control and closed-loop adjustment of the efficiency of the turbocharger of the engine have great effects on improvement of the utilization efficiency of exhaust energy and improvement of fuel economy.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine thermal management system and method. Background technique [0002] The intake and exhaust system of a diesel engine is mainly composed of an exhaust manifold, a turbocharger and related pipelines. The main function is to use the energy of the exhaust gas burned by the engine to drive the compressor to pressurize the intake air and increase the intake air density. [0003] In order to improve the economy of the engine and reduce fuel consumption, the utilization efficiency of exhaust gas, that is, the efficiency of the supercharger is an important part. In addition to the influence of the efficiency of the supercharger itself, the control of the engine on the efficiency of the supercharger also affects the supercharger. important part of efficiency. At present, the control mode of the supercharger is gradually upgraded from a passively controlled bypass valve superchar...
