Document Type and Number:
Japanese Patent JP2018172974
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To efficiently burn air-fuel mixture of a main combustion chamber in an internal combustion engine having an auxiliary chamber.SOLUTION: An internal combustion engine 1 has a main combustion chamber 12, an auxiliary chamber 24 arranged at a center of the main combustion chamber, plural communication holes 34 for communicating the auxiliary chamber and the main combustion chamber, an injector 46 for injecting fuel to the main combustion chamber, and a spark plug 42 having an ignition part arranged in the auxiliary chamber. By fuel injection of the injector, a high concentration area in which the concentration of fuel is relatively high, and a low concentration area in which the concentration of fuel is relatively low are formed in a circumferential direction of the main combustion chamber at an ignition timing. In the plural communication holes, a total sum of a flow passage area directed to the high concentration area is set larger than that of the flow passage area directed to the low concentration area.SELECTED DRAWING: Figure 2
