Work 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 improvement of the technology, the amount of the emissions produced depends on the method of the air injection used, and it varies. There are two types of the air injection systems. 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 turning screen filters the air as it enters to remove 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. 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 rhythms in the exhaust system at engine idle. With this system, it uses a reed valve assembly that is sensitive called the aspirator valve which is placed in the air injection pump. Injection pump draws air directly from the clean side of the air filter. During 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. This helps to clean up the leftovers hence assisting the car in to realize government emissions standards since the law requires an engine system that does not emit harmful gases after the combustion of the fuel. It helps save the power when there is loose ends, leaks, or any other illogical overflow. It makes the performance of the car improve 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 positioned with a tool precisely 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 break due to mechanical failure or constant use for a very long period. To support it; the vehicle owner needs to take the car for service. 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 .
