The significance of Using Secondary Air Injection System

Secondary air injection can be defined as the vehicle emission control panel wherein the fresh air is injected into the exhaust stream. This allows proper combustion of the exhaust gases. The secondary injection systems are categorized into two methods that are; the inspirited air injection and the pumped air injection. As follows are the benefits associated with using the secondary air pump.

The secondary air injection pump is utilized to decrease the hazardous substance emission during the cold starting. An affluent mixture is necessary for an excellent cold starting of a petrol engine. Therefore, the fuel in the fuel-air mixture will be extremely more. Consequently, it is capable of producing more carbon dioxide as well as the unburned hydrocarbons during the process of cold starting. During this moment, the oxygen sensor emission and also the catalytic converter will not have gotten to the operating temperature. Therefore, the toxic chemicals will escape into the atmosphere which is not treated. It’s thus necessary to use the secondary injection pump to minimize the harmful substances emitted during the cold starting. The reason for this is due to the high level of oxygen contained in the secondary air injection pumps and is injected to the exhaust gas manifold easily to the downstream of its exhaust valve. As a result, it causes the post oxidation of the toxic substances; therefore, it can generate the carbon dioxide and the water which is safe. The secondary air injection produces heat during this process that heats the catalytic converter. Therefore, it reduces the amount of time taken by the oxygen sensor emission ion the controlling of the commerce process.

When secondary air injection is used, it protects the environment. The reason for this is that the system helps to reduce the high concentration of carbon monoxide as well as the unburned hydrocarbons during the cold starting. As a result, it plays a major role in the contribution of the decreasing of the harmful substances emission to the atmosphere. Therefore, it enables some compliance with the current emission standards. This means that the secondary air injection can be used in the cleansing the leftovers.

The pump contains a fault utilized for the safety. The fault is capable of manifesting itself in for of the oscillating of the speed and the whistling noise produced during the cold starting process. There is an engine indicator lighting which is used for signaling the faults in the air injection pump. This enables the vehicle to turn to the minimized performed that involves an emergency operation.

The faults found in the secondary air injection system can be used for safety; this is because it can manifest itself in the form of oscillating the speed or the whistling noise that is produced during the cold starting. The engine indicator lamp lighting up is used to signal the faults in the secondary air system. Therefore the vehicle can turn to the reduced performance which is an emergency operation.
