Fuel supply control system for internal combustion engines

摘要

A fuel supply control system for an internal combustion engine. A load condition sensor detects a load condition of the engine, and an ECU increases the amount of fuel to be supplied to the engine when a predetermined high load condition of the engine is detected by the load condition sensor, and sets a delay time period from detection of the predetermined high load condition of the engine by the load condition sensor to execution of increase of the amount of fuel, according to operating conditions of the engine. A time period elapsed from the detection of the predetermined high load condition is counted. The set delay time period is corrected based on a ratio of the set delay time period to the counted time period and the load condition of the engine detected by the load condition sensor before the detection of said predetermined high load condition.
