【発明の名称】燃料噴射量制御装置
Document Type and Number:
Japanese Patent JP2765126
Kind Code:
B2
Abstract:
An apparatus for controlling a quantity of fuel injected into an internal combustion engine (1) comprises a sensor (50) for detecting atmospheric pressure (PA), a sensor (51) for detecting a load condition of an internal combustion engine (1), and an electronic control device (20) including a microprocessor (CPU) (100). The CPU (100) functions to perform the processing steps including: step (52) of setting a reference fuel injection quantity (t) in accordance with a load condition of the engine (1), step (53) of detecting a transient condition of the engine (1), step (54) of setting a transient correction value ( DELTA T) in accordance with the transient condition of the engine (1), step (55) of correcting the transient correction value ( DELTA T) to be decreased as the atmospheric pressure (PA) decreases, and step (56) of setting a quantity of injection fule (TAU) supplied to the engine (1) in accordance with the set value of the reference fuel injection quantity (t) and the corrected transient correction value ( DELTA T), whereby a deviation of an air fuel ratio from an appropriate value can be prevented even under a transient condition where atmospheric pressure (PA) varies.
