Fresh air is injected into the exhaust stream by the secondary air injection system which is the vehicle emission control panel. With the fresh air injected into the exhaust strea,, exhaust gases experience proper combustion. The inspirited air injection and the pumped air injection are the two methods or categories of secondary air injection systems. Below are some of the benefits of using secondary air injection pump.
The use of the secondary air injection pump is to lessen the hazardous substance emission during the cold starting. If you want a good cold starting of a petrol engine, then there is a need for an effluent mixture. This mixture can produce more carbon dioxide as well as the unburned hydrocarbon during the process of cold starting. During cold starting, the oxygen sensor emission, and the catalytic converter are still below their operating temperature. Because of this, toxic chemicals are allowed to escape into the atmosphere. It is possible to minimize the harmful substances escaping during cold starting and this is with the use of the secondary air injection pump. With the secondary injection pump, a high level of oxygen is contained in it which is injected to the exhaust gas manifold easily to the downstream of the exhaust valve. This causes the oxidation of toxic substances which can generate carbon dioxide and water which are safe. Heat is produced by the secondary air injection during this process. The catalytic converted is then heated. There is a reduction of time for the oxygen sensor emission to control the process.
One of the benefits of using secondary air injection is to help protect the environment. This is due to the reduction of a high concentration of carbon monoxide and unburned hydrocarbons during the cold starting. With this process, there will no longer be any harmful substances emitted into the atmosphere. You will then be able to comply with the emission standards currently being upheld. Leftovers can be cleaned by using secondary air injection.
In order to ensure safety the injection pump uses a fault. You can identify the fault during cold starting in the form of oscillating speed and the whistling noise. An engine indicator lighting signals faults in the air injection pumps. So, the vehicle then undertakes an emergency operation when this happens to that the vehicle will turn to reduced performance.
You benefit from using a secondary air injection system because it is maintenance free. Many factors lead to the soiling and sticking of your secondary air valves. A perfectly working secondary air system will help you pass the roadworthiness test of your vehicle.
There are many benefits to enjoy using secondary air injection pump not only to your car but to the environment as well.
