Fuel supply control/regulating system for combustion (IC) engine

摘要

The system has a high load condition detector to detect a preset maximum load condition of the machine and a fuel booster to increase the fuel supply (Tout) when the machine is in the maximum load condition. A temperature memory stores the temperatures of the catalytic converter (15) related to the operating conditions of the machine and means are provided to determine correction factors for values read out from this store which are used to estimate the temperature of the catalytic converter. The control/automatic control circuit then initiates boosting of the fuel supply if the maximum load condition is detected and if at the same time the estimated temperature is higher than a preset temperature
