Cooling-temperature-controllable-type engine intercooler assembly

Abstract

The invention relates to a cooling-temperature-controllable-type engine intercooler assembly, and belongs to the technical field of supercharged engine intercoolers. The cooling-temperature-controllable-type engine intercooler assembly comprises an intercooler, a front gas channel, a rear gas channel and a temperature adjusting valve; the intercooler is provided with a gas inlet hole and a gas outlet hole; the front gas channel is connected between the gas inlet hole and the gas outlet hole and used for circulating gas not passing through the interior of a cooling device; the rear gas channelis connected between the gas inlet hole and the gas outlet hole and used for circulating gas passing through the interior of the cooling device; and the temperature adjusting valve adjusts the gas temperature in the gas outlet hole by adjusting the opening degree of a gas outlet of the front gas channel and / or the rear gas channel. The interior of the intercooler is arranged into a cooling and non-cooling double-gas-channel form, and the temperature adjusting valve is arranged at the common outlet of the front gas channel and the rear gas channel; the temperature adjusting valve can control the mixing ratio of the gas in the front gas channel to the gas in the rear gas channel to meet the control requirement of the gas inlet temperature of an engine, and the gas inlet temperature of the engine is automatically controlled; and the temperature adjusting valve can adjust the temperature after intercool to enable gas inlet temperatures of all operating points of the engine to be controlledin the optimal state.

Description

technical field [0001] The present application relates to the technical field of supercharged engine intercoolers, in particular to an engine intercooler assembly with controllable cooling temperature. Background technique [0002] Supercharging and intercooling is an important technology to increase engine power and reduce emissions. Since the environment in which the engine is used on the vehicle is quite different from the environmental control conditions during engine development, when the engine is subjected to assembly calibration tests on the bench, The intercooler temperature is adjustable and controllable. During calibration, the intercooler temperature, intake air humidity, etc. will be precisely controlled according to the needs. Through the precise control of environmental conditions and meticulous calibration, the output power and exhaust emission level of the engine can reach the best state. . [0003] However, the cooling capacity of the environmental parts s...
