It is the process where fresh air is injected into the exhaust stream to allow fuller combustion of exhaust gasses. Due to improvement 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. These are the aspirated air injection system and the pumped air injection system. The Injected air injection, uses the method of the vape pump called the air pump. Smog pump. It is turned by the locomotive via electric motor or a belt. A rotating screen sifts the air as it enters to eliminate the large dirt particles that can damage the system. There is a check valve that prevents the exhaust from forcing its way back to the injection system which may harm the pump and the system. A diverter valve is used to prevent the startling and potentially damaging effects of the explosive combustion of this raw fuel.
Aspirated air injection uses the advantage of the negative pressure rhythms in the exhaust system at engine idle. This system uses a reed valve assembly that is sensitive called the aspirator valve which is located in the air injection pump. Injection pump draws air directly from the clean side of the air filter. In the course of the process of engine idle, periodic but brief negative pressure pulses in the exhaust system. The air is drawn through the aspirator valve and into the exhaust stream at the catalytic converter. The aspirator air injection system is beneficial in the sense that is economical, less in weight, in excellent packaging and simpler equated to the pump air injection system.
There is much importance of secondary air injector that makes it remarkable. It helps clean up the remains hence assisting the car in to accomplish government emissions standards since the law obliges an engine system that does not emit volatile gases after the combustion of the fuel. It helps save the power when there is loose ends, leaks, or any other illogical overflow. This improves the performance of the car at a more significant deal since there is proper maintenance of pressure throughout the exhaust system for the smooth running of the vehicle. Smog pump can be detached and placed with a tool specifically for this work which can help reduce weight and hence boost the power and performance of a car especially the racing vehicles.
Secondary air injection can fail due to mechanical breakdown or continuous use for a very long time. To regularly manage it, the owner of the vehicle needs to take the car for service annually. Repair of the system should be as soon as it shows signs of not performing. The possessor of the vehicle should use the car for specified number of miles before and after the service to avoid the air injection systems failing.
