Performance of Secondary Air Injection.

This process is where fresh air is pumped in to the exhaust stream to allow fuller combustion of exhaust gasses. Due to development of the technology, the amount of the emissions produced depends on the method of the air injection used, and it varies. Air Injection systems are in to two kinds. They are the aspirated air injection system and the pumped air injection system. The latter, uses the operation of the vape pump called the air pump. Smog pump. It is turned by the engine via electric motor or a belt. A turning screen filters the air as it enters to remove the large dirt particles that can damage the system. There is a check valve that stops the exhaust from forcing its way back to the injection system which may destroy the pump and the system. There is a diverter valve which is used to stop the startling and potentially damaging effects of the explosive combustion of this raw fuel.

Aspirated air injection uses the advantage of the negative pressure throbs in the exhaust system at engine idle. With this system, a reed valve assembly is used that is sensitive called the aspirator …
