Secondary Air Injection and Repair

This is a system that incorporates injection of air in vehicle exhaust systems. This is a technique of making sure that gases are fully combusted by injecting air from outside into a vehicle’s exhaust stream. The full combustion of engine gases brings about efficiency by generating more engine power.

The mode of air injection usually determines the mechanism by which emission of the exhaust gas can be manipulated. The point of secondary air injection also dictates the exhaust emissions mechanism and this has varied as technology advances. Initially, secondary air injection systems were installed and strategically placed so as to inject air in the cylinder heads, ports producing exhaust emissions or in the vehicle emission manifold.

Complete burning of fuel that had not been burned or that which was partially burned was enabled by these initial air injection systems. The aim of introducing these systems was to ensure that fuel was completely burned. With advancement in technology, effectiveness and efficiency was realized and the emission of unburned and partially burned fuel was minimized. With different air injection strategies introduced, effectiveness and efficiency was realized.

Air injection can be done in two distinct ways for better engine performance. For instance we have injection systems that use a pump in their operation. An engine is either used to turn the pump joined to it using a belt or an electric powered motor could be used to turn the pump. Introduction of air is done to the engine through minimal force. This method also involves the use of valves which stop the waste gas from the engine from flowing back to the air injection system thereby causing a damage to the pump.

The second method is whereby negative pressure built by the engine is used to cause air injection into the engine by allowing the engine to suck in air through designed ports. When the engine is idle, it sucks in the directed air in pulses from the exhaust system. The air injection strategy was employed by a famous vehicle producer and it has been effective.

Air injection systems work towards an advantageous aspect of minimizing and even eliminating the toxic gas being released to the environment by vehicles. The air is lesser toxic due to minimal toxic gases released from vehicle engines because they are able to give out more drive force than before. Cost effectiveness in the consumption of fuel is realized through the installation of air injection systems.

For better operating and results, these systems need to be monitored in several occasions and repaired if need be. The level of damage will determine whether a normal preservation or an overhaul of the air injection system will be done. In case of any mechanical problem or malfunction of the air injection system, a repair shop can be visited to provide the necessary solutions.
