The Key Elements of Great Automobiles

Significance Of Having Secondary Air Injection

Majority of the people have their own perception that some of the systems in the car are not of importance even some sites have not made it clear on their function, not so many people know about the secondary air injection and its function, it was first introduced in the late ninety’s where other may know it as the air injection which contains the secondary air valve and the secondary air pump which is basically considered as emission control of the car.

In order to have a reliable cold start the petrol engine needs a rich mixture this, therefore, means that the rich mixture does contain a lot of fuel which in turn has a large amount of carbon monoxide and unburned hydrocarbons which during the cold starting are produced, there is reduction of harmful substances being emitted when an individual uses the secondary air injection.

In most countries the secondary air injection is a must for every car so that it can attain the government emission standards, it is actually considered as a test for roadworthiness. With the use of the secondary air injection the environment is preserved this is because the emission of carbon monoxide and unburned hydrocarbon is reduced.

In the course of the cold start fuel is needed and with this secondary air injection helps to consume the excess fuel this helps to avoid the catalytic converter to get into contact with the fuel, also the tailpipe emission is improved in the process. Furthermore when the secondary air injection is used to prevent excess fuel from getting into contact with the catalytic converter then the reaction surface of the catalytic converter does not experience fouling this helps to improve the efficiency of the engine.
There is prevention of damage with the exhaust system with the help of the secondary air injection where any accumulated water vapor is blown out which would make the system to freeze, there is a necessity in this function because the system is able to detect there are low temperatures in the engine.

Since the secondary air injection contains the secondary air valves they do help to ensure only fresh air gets in the exhaust and when fresh air does not get in it may destroy the secondary air pumps especially when there is no vacuum and this in turn will result to the engine being destroyed.

The secondary air injection is also helpful to the human health this is because since it does reduce the emission of carbon monoxide and unburnt hydrocarbon, an individual does not consume this emission which can be really harmful to one’s health.
