Closed loop sequential fuel injection based on engine speed, torque and AFR

To control the flow of fuel in diesel engine by acquiring the demands of the engine. This is based on speed, torque and AFR. Due to vacuum a rising in suction stroke of CI engine. Atmospheric air is completely filled in combustion chamber during the end of the compression stroke. The fuel is injected through fuel injector. The amount of air and fuel which is coming into the combustion chamber, in accordance with its specific speed and torques so the amount of fuel injection may be excess or insufficient. This may cause higher emission and fuel economy is reduced. By injecting the fuel in sequential manner we are able to reduce the emission and increase the fuel economy.
