Speed Disturbance in the Diesel Engine Electronic Control System

In order to sample the speed signal of electr onic diesel eng ine in real time and make the eng ine wor k reliable, the diesel eng ine control systems speed acquisit ion was studied and the problem of speed distur bance w as solved. The control system was based on the 8 bit electronic control unit( ECU) system and the assembly language was used to design the software for controlling the eng ine fuel quantity and the turbocharger of the variable geometr y turbine for the heavy??duty diesel engine. By chang ing the timing method fo r speed acquisition, the problem of speed disturbance w as solved and the r eliability of the ECU w as improved.
