This air injection system has the responsibility of maintaining low carbon monoxide and hydrocarbon; this sub-system has an air supply pipe, an air control valve, a check valve injection tubes and connecting hoses. It works by blowing in fresh air into the hot exhaust stream, thus achieving more combustion of the remaining mixed gases, thus minimizing emission and making some of them to evaporate into carbon dioxide and water. At other operating modes, e.g. higher engine speed, the air control valve dumps air to the atmosphere to prevent overheating of the exhaust system. There are three types of air control valves: a relief valve that controls the amount of output of the pump; a diverter valve that ensures that back firing does not occur during occasions like rapid deceleration; and the switch/relief valve that directs the flow of the air injection depending on engine heat . To do this, stop the engine and with the air supply hose disconnected, one should be able to feel air flow at the pump outlet. In the event that the pump is damaged, it should be replaced that is if there is enough budget. Concerning the relief and diverter valves, if the noise is loud or is air, then there is a problem and the valves must be replaced. Grossly, the switch/relief valve should not release air at idle; if it does, then the valve must be changed. The check valve is checked by examining its inlet tube, for exhaust gas; if experienced, the check valve needs replacement. Some specifications need to be met as follows; when removing fittings, mark the hoses for reconnection, replace any damaged parts, and be certain that all gaskets are new and the hoses are in good condition. For the air supply pump, slacken the drivebelt, replace the ruined unit with the undergoing label wires and hoses and tighten the new pumps' drivebelt to the correct tension.
