Work of Secondary Air Injection.
This is the process where fresh air is injected into 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. There are two types of the air injection systems. These are the aspirated air injection system and the pumped air injection system. The latter, uses the system of the vape pump called the 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 benefit of the negative pressure pulses 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 propel draws air straight 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 strained 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. 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 fail due to mechanical breakdown or continuous use for a very long time. To maintain it, the owner of the vehicle need to more often 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 .
