How important is the secondary air injection system?
Thus, the secondary air injection system is there to help clean up the leftovers. The air injection smog pump pushes air into the exhaust system right after the exhaust manifold, to help intercept and burn those unburned fuels. The system is critical to help cars achieve government emissions standards.
How does a secondary air injection work?
Secondary air injection systems pump outside air into the exhaust stream so unburned fuel can be burned. The system injects the correct amount of air using inputs like coolant temperature, air temperature and oxygen sensors.
What happens to the secondary air injection system?
Therefore, preventing the exhaust fumes from, leaking back into the secondary air injection system. When the air pump diverter valve fails, it can lead to a variety of problems. In addition to a significant increase in the vehicle’s, tailpipe emissions.
Why do we need an air injection system?
All we have to do is introduce some oxygen, than any unburned fuel will ignite. So, the air injection smog pump pushes air into the exhaust system, right after the exhaust manifold. Therefore, helping intercept and burn those unburned fuels. Above all, the system is critical to help engines achieve government emissions standards.
What causes an air injection pump to fail?
The air injection pump relay contacts, not making contact. So, a faulty pump is generally the most frequent cause, of the system failing. Also, too much moisture can cause damage which results in, seizure of the pump. Finally, a faulty ground and voltage supply, can also cause the pump to fail.
Where does the air injection smog pump go?
Consequently, inside the exhaust manifold, there is sufficient heat, to support combustion. All we have to do is introduce some oxygen, than any unburned fuel will ignite. So, the air injection smog pump pushes air into the exhaust system, right after the exhaust manifold.
