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. 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 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. 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. 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 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 thrust draws air directly from the clean side of the air filter. Through the operation of motor idle, periodic but short negative pressure pulses in the exhaust system. The air is drained through the aspirator valve and into the exhaust stream at the catalytic converter. The aspirator air injection system is essential in the sense that is cheap, less in weight, in excellent packaging and more straightforward compared 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. The power is saved when there is slack ends, leaks, or any other unreasonable 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 fail due to mechanical breakdown or continuous use for a very long time. To support it; the vehicle owner needs to take the car for service. The system should be fixed as fast as it indications signs of malfunctioning. The vehicle owner should use the car for specified number of miles before and after the service to prevent the air injection systems malfunctioning .
