PROBLEM TO BE SOLVED: To provide a pressure intensifying cylinder of a vehicle air inlet structure. SOLUTION: Two mutually penetrating first hole path and second hole path are formed in the radial direction of a cylinder wall of a cylinder body 1. An air pipe of a brake auxiliary unit is connected to the first hole path, and a second hole path air inlet manifold is connected. A third hole path 13 communicating with an external part is formed in the axial direction of the cylinder body 1, and a through-pipe 14 is arranged in a passage of the third hole path, and a first filter 15 and a second filter 16 are arranged on both ends of the through-pipe. A net layer 151 is arranged on an outside end surface of the two filters, and a hole path of converging an inner diameter inside from the outside in a plurality of axial directions, is formed in the net layer. Since the check valve effect is formed so as to be easy in entering and difficult to go out, hot gas of external air and an internal carbon remnant stays for a predetermined time, and thus, the external air (a combustion assist), the temperature (an ignition point) and a combustible carbon deposit (combustibles) can acquire a combustion time for staying by being mixed, and the carbon deposit can be reduced.
