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. These 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 rotated by the engine 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. 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. 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. 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. 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 are a several advantages of secondary air injector that makes it outstanding. It helps clean up the leftovers hence helping the car to achieve state’s emissions standards since the rule requires an engine system that does not emit poisonous gases after the combustion of the fuel. The power is saved when there is slack ends, leaks, or any other unreasonable 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. The system should be fixed as fast as it indications signs of malfunctioning. 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.
