Automatic tire inflation systems use pressurized air to maintain tire pressure. Air enters a control box, where it is regulated to the desired tire psi. Then, air moves through a rotary union and travels via tire hoses. This process ensures proper air transmission and keeps tires properly inflated, enhancing functionality and safety.
These systems actively monitor tire pressure and adjust it as needed. Sensors placed in each tire collect data about pressure levels and send this information to a control unit. The control unit processes the data and determines if inflation or deflation is necessary. If adjustments are needed, the system activates pumps to inflate the tires or release air to maintain the desired pressure.
Maintaining proper tire pressure enhances vehicle safety and increases fuel efficiency. Under-inflated tires can lead to poor handling, increased wear, and reduced fuel economy. Conversely, over-inflation may result in decreased traction and a higher risk of blowouts.
The design of CTIS facilitates quick changes in tire pressure based on driving conditions. This adaptability proves essential for off-road vehicles that encounter varying terrains.
