engine air intake

Abstract

The invention relates to an air inlet device of an engine, and the device can separate absorbed foreign matters of outdoor air and guide the low-temperature outdoor air into the engine. An air exhausting device is arranged on the front part of the engine in a engine compartment, the air inlet device comprises an outdoor air inlet pipeline, an outdoor air inlet port is arranged on the front of the main body and on the front side of the air exhausting device, an outdoor air outlet port is arranged on the rear of the main body and away from the outdoor air inlet port in vehicle width direction, an openning of the outdoor air inlet port forms as a side wall across a front wall of the main body and extending from the end of the fromt wall to the rear of the vehicle, a guide wall is arranged on the rear of the front side edge of the outdoor air inlet port and is arranged nearer the inner side of the main body than the end of the outdoor air inlet port in the vehicle width direction, the upper and lower ends of the guide wall are connected with the inner surface of the main body, the front surface of the guide wall is inclined to a rear wall which is closer to the main body fron the inner side to the outter side of the main body in the vehicle width direction.

Description

technical field [0001] The present invention relates to an air intake device for an engine, and more particularly to an air intake device for an engine capable of introducing low-temperature external air into the engine while removing foreign matter. Background technique [0002] The air intake device of the engine arranged in the engine compartment of the vehicle is provided with an external air introduction duct at the front of the engine compartment. The intake pipe connected to the outside air outlet introduces the outside air introduced from the outside air inlet of the outside air introduction duct into the engine. [0003] The outside air introduction duct that sends outside air to the engine arranges the outside air inlet toward the front of the vehicle, thereby allowing outside air to be introduced during driving. When idling while parked, outside air heated by the exhaust system is introduced, and water droplets are sucked in when it rains. [0004] Therefore, re...
