Automatic Air Inflation Project
Mechanical Engineering Final Year Projects
The overall goal of this design project is to develop a system that will decrease tire wear while improving fuel economy, performance, and safety of a passenger vehicle through dynamically adjustable tire pressures. The system serves to solve a fairly common problem of improperly inflated tires, which also are the cause of many road accidents, thereby increasing the safety of the passengers.
The system mainly consists of four components, namely, Rotary Union, Pressure Switch, Solenoid Valve, and Portable Compressor. As soon as the tire pressure goes below the set lower limit, the Pressure Switch sends an electrical signal to the Solenoid Valve and the Compressor. Compressed air flows through the Rotary Union into the tire thus inflating the tire. As soon as the higher set limit of the pressure switch is reached the switch shuts off and the circuit breaks.
