Abstract

An air compensation device of an internal combustion engine comprises an engine air inlet header pipe (14), a body (1), an air connector (2) and a solenoid valve (3). The body (1) is internally provided with a first air compensation channel (7) and a second air compensation channel (8). The engine air inlet header pipe (14) is provided with an air inlet hole communicated with the first air compensation channel (7). The solenoid valve (3) is a membrane-type solenoid valve, and installed in a solenoid valve installation hole (16) in the body (1). The first air compensation channel (7) is connected with the second air compensation channel (8) through a membrane (10) inside the solenoid valve (3), one end of the air connector (2) is communicated with the second air compensation channel (8), the other end of the air connector (2) is communicated with an air inlet pipe before a throttling valve body (15) through a pipeline, and the solenoid valve (3) is electrically connected with a vehicle electronic control module. The demand for air during braking of an engine is met.

Description

technical field [0001] The invention relates to a vehicle air compensation device, more specifically to an internal combustion engine air compensation device, which belongs to the technical field of vehicle gearboxes, and is especially suitable for supercharged, premixed internal combustion engines with engine braking. Background technique [0002] According to the way the mixture is formed, the internal combustion engine is divided into premixed type and in-cylinder direct injection type. The premixed internal combustion engine refers to the engine in which air and fuel are pre-mixed into combustible gas in the intake manifold, and then burned in the cylinder; premixed type There is a throttle body in front of the intake manifold of the internal combustion engine, see Figure 11 A throttle valve body 15 is installed in front of the engine air intake manifold 14, and the opening degree of the butterfly plate 17 of the throttle valve body 15 affects the flow area of ​​the inta...
