Internal combustion engine air inlet system structure for vehicle

Abstract

The invention relates to an internal combustion engine air inlet system structure for a vehicle. The vehicle is provided with a frame unit, an engine unit which is hung on the frame unit, the engine unit is connected with an air inlet system capable of supplying clean fresh air; a seat cushion capable of being lifted is arranged on the frame unit, a storage box is arranged below the seat cushion;the engine unit is provided with a power generation part and a transmission part, the power generation part is provided with air inlet ports, the transmission part can drive wheels; the air inlet system at least comprises an air inlet pipe to communicating the air inlet ports and a throttling valve body; the air inlet system further comprises a dust falling unit arranged at the front end of the storage box, the dust falling unit is provided with an air suction port, and the air suction port is arranged below the front end of the seat cushion. According to the internal combustion engine air inlet system structure, the air inlet system can provide sufficient clean fresh air required by high-speed operation of the engine unit, and space on a vehicle body can be fully utilized.

Description

technical field [0001] The present invention relates to a structure of an internal combustion engine air intake system for a vehicle, especially the air intake system that can provide enough clean and fresh air for the high-speed operation of the engine unit, and can make full use of the space on the vehicle body. The structure of the intake system of the internal combustion engine of the vehicle. Background technique [0002] The action of a general internal combustion engine vehicle, take motorcycle A as an example, this motorcycle A is to mix the clean air and fuel oil introduced from the outside into oil and gas, and then input the oil and gas into the engine unit 1 to explode to generate power, and push the piston Do reciprocating motion, and drive the transmission part 11 to drive through the crankshaft, so as to achieve the purpose of advancing. [0003] Such as figure 1 As shown, in order to ensure the cleanliness of the air entering the engine unit 1 from the outs...
