This process is where fresh air is pumped in to the exhaust stream to allow fuller combustion of exhaust gasses. Due to advancement of the technology, the amount of the emissions produced depends on the process of the air injection used and it changes. There are two types of the air injection systems. They include 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 locomotive via electric motor or a belt. A rotating filter cleans the air as it enters to get rid of the large dirt particles that can damage the system. The check valve prevents the exhaust from pushing its way back to the injection system which may damage the pump and the system. The diverter valve is used to avert the unexpected and possibly harmful effects of the unstable combustion of this raw fuel.
Aspirated air injection uses the advantage of the negative pressure throbs 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. This aspirator air injection system is vital in the sense that is inexpensive, less in weight, in excellent packaging and more unaffected in comparison to the pump air injection system.
There are a several advantages of secondary air injector that makes it outstanding. 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 removed and placed with a tool specially for this work which can help reduce weight and hence boost the power and performance of a car especially the racing cars.
Secondary air injection can break due to mechanical failure or constant use for a very long period. 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 vehicle owner should use the car for specified number of miles before and after the service to prevent the air injection systems malfunctioning .
