AI Technical Summary

Problems solved by technology

[0004] from figure 1 It can be seen that the existing throttle valve implementation scheme can control the intake air volume of the engine, but under different intake air volumes, the heat exchange conditions of the intake air are fixed (generally close to the ambient temperature)
Therefore, in the case of low temperature and small load, neither fuel economy nor engine emission can be effectively guaranteed

Abstract

The invention discloses a temperature control throttle valve device. The temperature control throttle valve device comprises at least one throttle valve body, a first pipeline and a second pipeline, wherein the first pipeline and the second pipeline are connected to the same side of the air flow direction of the at least one throttle valve body in parallel, and the second pipeline is provided witha heat exchanger which uses an engine coolant, engine oil or engine exhaust as a heat source to heat air flowing through the second pipeline.

Description

technical field [0001] The invention relates to the field of air intake control of an engine, and more specifically relates to a temperature control throttle device capable of controlling the intake air temperature of an engine. Background technique [0002] Generally speaking, ignition engines (including at least ignition gasoline engines and ignition natural gas engines) use a throttle valve to control the amount of intake air to the engine, thereby controlling the engine load. [0003] figure 1 It is a schematic diagram showing a conventional spark ignition engine throttle valve and intake pipeline. Such as figure 1 As shown, engine intake air enters from an air filter 100 , is connected to a throttle valve 103 through a line 101 , and enters the throttle valve 103 from a throttle valve inlet 102 . According to the load requirements of the engine, the throttle valve body 104 rotates, thereby regulating the air flow into the engine through the throttle valve 103 . The ...
