Fuel supply control method for internal combustion engines under high load conditions

摘要

A fuel supply control method for an internal combustion engine, in which while the rotational speed of the engine is lower than a predetermined value, the mixture is enriched either when a detected value of absolute pressure in the intake pipe of the engine is higher than a first predetermined value or when a detected value of the throttle valve opening is larger than a predetermined value, whereas while the rotational speed of the engine is higher than the predetermined value, the mixture is enriched when a detected value of the intake pipe absolute pressure is higher than a second predetermined value, thereby preventing an excessive increase in the bed temperature of the catalyst device of the engine, as well as ensuring required output performance of the engine.
