Abstract

The invention provides a temperature adjusting system, an engine and a temperature adjusting method, the temperature adjusting system is used for adjusting the exhaust gas temperature of the engine, the temperature adjusting system comprises an adjusting pipeline, an air inlet of the adjusting pipeline is communicated with a bent pipeline of the engine, and an air outlet of the adjusting pipeline is communicated with an exhaust pipeline of the engine; the heating device is arranged on the adjusting pipeline so as to heat a medium flowing through the adjusting pipeline; and the control valve is arranged on the adjusting pipeline so as to control the flow of the medium in the adjusting pipeline. The problem that in the prior art, an engine exhaust gas temperature adjusting mode cannot give consideration to various use environments of the engine is solved.

Description

technical field [0001] The present invention relates to the technical field of engine exhaust temperature regulation, and in particular, to a temperature regulation system, an engine and a temperature regulation method. Background technique [0002] With the continuous development of high-efficiency automotive power systems, high-efficiency engines, such as hybrid engines, lean-burn engines, and other high-thermal-efficiency engines have attracted much attention. [0003] However, while high thermal efficiency brings high efficiency, it results in low exhaust gas temperature, and the exhaust after-processor needs to work at a suitable temperature to achieve high conversion efficiency. Therefore, engine exhaust temperature regulation is becoming more and more important. [0004] In the prior art, the engine exhaust temperature is adjusted in two ways: the internal temperature adjustment or the external temperature adjustment. The internal exhaust temperature adjustment method...
