The embodiment of the invention provides an engine gas inlet device, an engine system and an automobile. A throttle body, a throttle and a waste gas flow guide device are included; the throttle body forms a part of a gas inlet channel communicated with a burning chamber of an engine; the throttle is used for opening and closing the gas inlet channel of the throttle body; the waste gas flow guide device is used for sucking in waste gas and carries out flow guide on the waste gas; and the waste gas flow guide device comprises an intake manifold and a pressure stabilization unit welded to the intake manifold, and an isolation plate is arranged in the pressure stabilization unit. According to the engine gas inlet device, the engine system and the automobile, crankcase waste gas channel flow dividing is achieved, the possibility that the channel is blocked is reduced, and normal work of the engine is guaranteed; by means of the pressure stabilization unit and the two-stage isolation plate arranged in the pressure stabilization unit, separated crankcase waste gas is subject to pressure stabilization treatment, and it is guaranteed that the waste gas is evenly gathered into all gas cylinders of the engine; and a crankcase waste gas outlet is far away from the throttle body of the engine, pollution of the crankcase waste gas to the throttle body is avoided, and engine abnormities are prevented.
Description
technical field [0001] The invention belongs to the technical field of automobiles, and relates to an automobile engine air intake device, an engine system and an automobile. Background technique [0002] With the development of social economy, people's living standards have been greatly improved, and people's consumption levels have also gradually increased. Motor vehicles, especially automobiles, as a major means of transportation, are becoming increasingly popular in people's lives. And growth, has gradually become a popular main means of transportation. [0003] The throttle body is a device on the engine intake system, a valve used to control the engine's air intake. The traditional throttle body is generally a circular steel sheet with a shaft in the middle, which is connected to the throttle cable and controlled by the throttle cable. The throttle body is generally composed of three parts: the actuator, the throttle plate and the throttle position sensor, which are ...
