ABSTRACT:
An air-inlet assistor for vehicle engines is provided which connects to the engine with an inlet pipe. The air-inlet assistor includes a main body, an upper magnet and a lower magnet contained within the main body, and an air cleaner. The inner cavity of the main body is divided into an upper working chamber and a lower inlet chamber. The upper and lower magnets are disposed within the working chamber with like poles thereof being face to face, to generate a repelling force therebetween. An inverted cone is disposed on the bottom side of the lower magnet to seal an opening formed between the working chamber and the inlet chamber. When the engine is started, a drawing in force generated by vacuum in the engine makes the upper and lower magnets move together to break the seal in the opening formed in a partition board that separates the two chambers. The outside air can then flow through the air cleaner into the inlet chamber, pass through the openings in the partition board into the working chamber and flow through the inlet pipe to get to the engine, for automatically maintaining the balance of the air-inlet.
