LOAD CONTROL CIRCUIT AND METHOD FOR EFFECTING THE EMERGENCY OPERATION OF AN INTERNAL COMBUSTION ENGINE

摘要

During the failure or disruption of the data interchange between the valve control unit (1, 2) and the operation control unit (9) of an internal combustion engine comprising electromechanically actuated intake valves (5a, 5b), the valve control unit (1, 2) changes the electromechanical actuation of the intake valves (5a, 5b) to full load control times, and the operation control unit (9) adjusts a throttle valve (12) in order effect the load control of the internal combustion engine in a manner which no longer uses valve load control, but uses throttle valve load control during emergency operation.
