Abstract: PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of effectively suppressing generation of knocking while increasing the output of the engine. SOLUTION: An engine 1 to perform fuel injection in a compression stroke by using super-high pressure fuel generates disturbance in fuel spray to be injected in a combustion chamber 2, and adjusts the timing of attenuation of the disturbance through adjustment of the fuel injection timing. Ignition is performed at the timing when the fuel spray is in an adequately disturbed state, and the knocking sensitivity is minimized thereby. Since the knocking sensitivity is minimized, the actual ignition timing is brought close to the ignition timing corresponding to the maximum value of the generated torque.

Abstract: PROBLEM TO BE SOLVED: To provide a spark igniter of a one-cylinder two-point ignition type in which secure ignition and favorable combustion can be realized.
SOLUTION: For two-point ignition, two flame surfaces generate higher pressure than that around them, and mutual action of the two flames is generated to push each other. The two flames are thus more quickly grown toward peripheral parts of a combustion chamber than to a center part of the combustion chamber. Taking size of a line through center parts of two pairs of electrodes 11, 12, 21, and 22 for reference size, distance L1 between the center parts of the respective electrode pairs is set to be over 2 mm, and less than 1/2 of the reference size. Effect of two-point ignition is thus securely achieved, and more secure ignition and favorable combustion can be realized.
