Title:
燃料噴射制御装置
Document Type and Number:
Japanese Patent JP5647927
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To accurately control the injection of gaseous fuel even when a gaseous fuel injection valve is coupled to an air intake pipe via a tubular member.SOLUTION: A fuel injection control device controls the gaseous fuel injection valve 4 coupled to the air intake pipe via the tubular member. The fuel injection control device is configured: to calculate the amount of gaseous fuel remaining in the tubular member based on the capacity of the tubular member and an internal pressure of the air intake pipe every time a gaseous fuel injection amount is calculated; to calculate the mount of gaseous fuel to be injected in the current injection based on the amount of remaining gaseous fuel in the previous injection and the amount of remaining gaseous fuel in the current injection; and controlling the gaseous fuel injection valve 4 according to the result of the calculation.
