Abstract

The invention discloses a diesel engine air supply system based on fuzzy algorithm optimization. The diesel engine air supply system comprises a pressurized air pressure collector, a rack position signal collector and a control processor. The pressurized air pressure collector is in circuit connection with the control processor and is used for collecting a pressurized air pressure value; the rack position signal collector is in circuit connection with the control processor and is used for collecting the rack position of a diesel engine fuel rack; the control processor is in circuit connection with the air supply electromagnetic valve, and the control processor forms a control signal for controlling the on-off of the air supply electromagnetic valve through a fuzzy algorithm based on the pressurized air pressure value and the position of the rack. The invention can increase the rotating speed of the supercharger at the moment of sudden loading of the diesel engine, accelerate the increase of air pressure entering the cylinder, improve the combustion environment in the cylinder, reduce black smoke generated by the diesel engine, improve the working performance of the diesel engine and realize the purpose of environmental protection.

Description

technical field [0001] The invention relates to the technical field of ship air supply control, in particular to a diesel engine air supply system optimized based on a fuzzy algorithm and an air supply method thereof. Background technique [0002] Marine diesel engines usually use supercharging and intercooling technology to increase the air density entering the cylinder to improve the performance of the diesel engine. Turbocharging technology uses the inertial momentum of the exhaust gas discharged from the diesel engine to drive the turbocharger turbine, and the turbine drives the coaxial impeller, which presses and sends air to pressurize it into the cylinder of the diesel engine. When the load of the diesel engine increases, it will burn more fuel, and its exhaust gas discharge will also increase accordingly. The turbine speed will also increase synchronously, and the impeller will compress more air into the cylinder. Therefore, when the turbocharger matches the diesel e...
