Funcionament
The secondary air injection system introduces fresh air into the exhaust stream during specific engine operating conditions, typically during cold starts. This additional air helps to burn off uncombusted fuel in the exhaust, reducing harmful emissions. The check valve, such as the Dorman 911-153, is a one-way valve that allows air from the air pump to enter the exhaust system but prevents hot exhaust gases from flowing back into the air pump. This protection is crucial for the longevity and proper function of the air pump and the entire emissions system.
