Patent ID: 8899211

Claim:
An internal combustion engine controller comprising: a starting section that starts an internal combustion engine by performing fuel supply into part of a plurality of cylinders included in the internal combustion engine; a fuel supply starting section that starts fuel supply into at least one remaining cylinder of the plurality of cylinders after a magnitude of a negative pressure produced in intake piping of the internal combustion engine exceeds a predetermined reference value; and a jumping-up detecting device that detects jumping up of a rotational speed of the internal combustion engine; wherein the starting section performs fuel supply into part of the plurality of cylinders in the internal combustion engine before the magnitude of the negative pressure produced in the intake piping of the internal combustion engine exceeds the predetermined reference value, when a number of the remaining cylinders is equal to or greater than two, the fuel supply starting section sets a retarded start cycle number for one of the retarded start cylinders that differs from a retarded start cycle number for another of the retarded start cylinders, the retarded start cycle number being a number of cycles, by which start of the fuel supply is retarded, that is, a number of cycles, in which the fuel supply is stopped in the corresponding retarded start cylinder; wherein the fuel supply starting section increases the retarded start cycle number of at least one of the remaining cylinders when the jumping-up detecting device detects the jumping up.
