Title:
DISPERSION DETECTING DEVICE OF AMOUNT OF SUCTION AIR
Document Type and Number:
Japanese Patent JP3960339
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a dispersion detecting device of amount of suction air between cylinders in an internal combustion engine having a plurality of cylinders to detect unevenness in amount of suction air between the cylinders accurately.
SOLUTION: Amount of fuel injection is changed into either of an increase side and a reduction side from amount of injection at stoichiometric operation. Change allowance of torque or rotational speed at the time is obtained, and the obtained change allowance of torque or rotational speed is outputted as an index value for showing degree of unevenness in amount of suction air between the cylinders.
