A secondary air injection is a strategy that is used in motor vehicles emission systems in order to control the emissions. These devices were introduced around five decades ago. The principle of operation of the secondary air injection system is through the introduction of fresh gases from the environment to aid in the total burning of waste gases.
The principle of operation of the secondary air injection system usually depends on the mode of the injection of the fresh air as well as where it is injected into the mechanism. These modes of operation of the secondary air injection system have varied with type with the development of technology. There has been a great reduction in the emission of dangerous gases to the atmosphere from cars by the use of the secondary air injection system.
The secondary air injection system is able to run for a very long time before needing any maintenance. Even though the secondary air injection system requires low maintenance, it is important to observe good means of operation to avoid faults in the mechanism. A good operation of the secondary air injection system leads to it being effective and efficient.
When the secondary air injection system is faulty, it will be observed in the idling speed of the vehicle or a strange sound in the event of an engine cold start. In petrol engines a rich mixture is usually required for cold starting. A very high level of the petrol usually leads to the release of toxic gases from the motor vehicle during the cold start of the engine. There is usually a disadvantage related to the unwanted temperatures of the secondary air injection system. You should always visit a reliable and qualified personnel for the regular servicing and repair of your secondary air injection system.
In the reduction of the emission of the toxic waste from vehicles, oxygen is usually introduced into the emission manifold directly. The process usually result in the emission of carbon dioxide and water which have been neutralized. The raised temperature in the emitted gases also plays an important role in the functioning of the secondary air injection system.
The secondary air injection system is usually made up of an air pump and also some secondary air valves. The secondary air pump in this system is supposed to suck in the fresh air and force it into the exhaust gas stream. The air regulating devices are usually installed between the secondary air pressure pump and the emission manifold. The secondary air injection system is usually considered the most effective method of minimizing the amount of harmful gases released from a motor vehicle engine. With the advancement of the secondary air injection systems with technology, the amounts of exhaust gases which were either unburned or partially burned reduced drastically.
