The price of the ancient internal combustion engine for the vehicle is generally three-fold of a new product or even lower, particularly the price of the internal combustion engine for a scrapped vehicle is lower, and most of the internal combustion engines are good when the internal combustion engine production technology is quite mature and the general vehicles are scrapped, so that the sources are quite sufficient and the price is low, the damage rate is extremely low due to the maturity of the internal combustion engine production technology, and a large number of ancient parts are replaced even if maintenance is needed, so that the invention is known to be combined with the ancient cylinder unit 1 in the ancient (second-hand) internal combustion engine for the vehicle to compress air, so that the production cost is greatly reduced, and the selling price of the finished product is also reduced, therefore, the invention effectively improves the problem that the air compressor is generally expensive, overcomes the problems existing for a long time in the technical field of air compressors, and benefits from the maturity of the internal combustion engine production technology, the problems that the cylinder unit 1 is excellent in quality, durable and expensive in subsequent maintenance are also improved by having a large number of the used parts to be maintained and replaced.
