Air intake system and vehicle

Abstract

The invention provides an air intake system and a vehicle, and relates to the technical field of vehicles. The air intake system comprises an air damper and air intake manifold branches. The air damper is used for adjusting the air intake amount of air entering an engine. The air intake manifold branches are arranged above the air damper and communicate with the air damper. The pipe wall of each air intake manifold branch is provided with a first heating device used for heating the pipe wall of the air intake manifold branch, so that water vapor inside air is prevented from coagulating on theinner wall of each air intake manifold branch. By the adoption of the structure, the heating devices are arranged at the pipe walls of the air intake manifold branches and heat the pipe walls of the air intake manifold branches, the temperature difference between the inner walls of the air intake manifold branches and intake air is reduced or even eliminated, the temperature of the pipe walls is greater than or equal to the air intake temperature of air, vapor inside the air is prevented from coagulating on the inner walls of the air intake manifold branches to form frost, the source of condensate water is eliminated, freezing of the air damper is effectively avoided, and it is ensured that working is reliable when the engine is in cold start in cold winter.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an air intake system and a vehicle. Background technique [0002] The throttle body of the engine includes a casing and a throttle valve, and is a device for controlling the power output of the engine. When the weather is cold, the position of the throttle valve will freeze, which seriously affects the gas circulation near the throttle valve, deteriorates the performance and fuel consumption of the engine, and makes it difficult to start the engine. Therefore, throttle valve icing and engine cold start problems have always been a major problem that plagues automobile engine starting. [0003] At present, the common method to solve the icing of the throttle valve is to have its own heating system or ice-breaking function. However, the above methods cannot fundamentally solve the throttle valve freezing problem. Contents of the invention [0004] An object of the present inve...
