摘要： PROBLEM TO BE SOLVED: To provide a stop control device of an internal combustion engine capable of stopping its piston accurately in a prescribed position in accordance with an amount of fuel remaining in a cylinder when the engine is stopped.
SOLUTION: The stop control device 1 of the internal combustion engine 3 controls a throttle valve 13a into a closed side when an ignition SW 21 is turned off, and then controls the valve 13a into an opened side when engine speed NE becomes lower than a first stage control start speed NEICOFPRE (see Figs.5 and 6). As a pre-stop fuel injection amount TCYLIGOF becomes large, the NEICOFPRE and a target stop control starting speed NEICOFREFX are corrected to a smaller side (Steps 31 and 32), and thereby a piston 3d is stopped in the prescribed position accurately in accordance with the amount of the fuel remaining in the cylinder 3a when the engine 3 is stopped.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus to control an internal combustion engine capable of maintaining stable combustion by preventing adhesion of carbon on an ignition plug of a deactivated cylinder due to a cylinder deactivation operation with a relatively simple method.SOLUTION: When a cylinder deactivation operation is performed, a cylinder deactivation counter CCSPLUG calculates a count value corresponding to an integrated value of a deactivation time of a cylinder. When the value of the cylinder deactivation counter CCSPLUG is equal to or larger than a two-cylinder deactivation inhibition threshold CCS2PLUGH, a two-cylinder deactivation operation is inhibited, and when the value of the cylinder deactivation counter CCSPLUG is equal to or larger than a three-cylinder deactivation inhibition threshold CCSPLUGH, the two-cylinder deactivation operation and a three-cylinder deactivation operation are inhibited (S51-S54). The count value of the cylinder deactivation counter CCSPLUG is held after an engine 1 stops. In starting the operation next time, the integration by the cylinder deactivation counter CCSPLUG is performed using the held count value as an initial value.

摘要： PROBLEM TO BE SOLVED: To provide a control device for stopping an engine without making a stop position of a piston get out of order and without worsening emission when air is introduced by opening a throttle valve for avoiding stop of the piston near a top dead center after an ignition switch of the engine is turned off.
SOLUTION: A device for controlling timing for stopping ignition in stop of the internal combustion engine includes: a means for transmitting signal to an actuator 18 to open the throttle valve 14 for controlling the stop position of the piston when rotation speed NE of the internal combustion engine detected by a rotation speed sensor becomes predetermined value Np or less after the ignition switch 55 is turned off and the throttle valve 14 is closed; and a means for stopping ignition of a spark plug when the throttle valve 14 is opened for controlling the stop position of the piston.
