摘要： PROBLEM TO BE SOLVED: To provide a spark-ignition internal combustion engine in which occurrence of engine knocking is inhibited even though the constitution is simple. SOLUTION: In an intake stroke, an air-fuel mixture injected from an intake-port fuel injection valve 21 is introduced into a combustion chamber 13, and pre-mixture 31 having a homogenous concentration-distribution is formed in the inside of the combustion chamber 13. In a compression stroke, a cylinder injection of fuel is effected from a direct fuel-injection valve 22 to the peripheral part in the with of the combustion chamber 13 to form a mixture layer 32 having nonhomogeneous concentration-distribution around the periphery within the combustion chamber. The pre-mixture 31 in the center of the combustion chamber 13 is ignited by an ignition plug 23 to cause flame-propagation combustion of the mixture 31, 32 within the combustion chamber 13. Nonhomogeneous mixture layer 32 is present on the periphery within the combustion chamber 13. Thus, even though a self ignition is locally generated around the periphery of the combustion chamber 13, the self ignition is inhibited from instantaneously spreading into other areas.

摘要： PROBLEM TO BE SOLVED: To raise the degree of freedom of position for ignition of mixture, so as to ignite the mixture at an appropriate position within a combustion chamber.
SOLUTION: Since an annular electrode 10 for ignition is attached to a top surface 11a of a piston confronting the combustion chamber 3 with an insulator 12 interposed in between, the ignition electrode 10 and the piston 11 are electrically insulated from each other. Electromagnetic waves radiated from an electromagnetic wave radiator 4 fill the combustion chamber 3. In the vicinity of the ignition electrode 10, the electric field intensity of the electromagnetic waves is locally increased from the difference in magnetic permeability between the ignition electrode 10 and the space within the combustion chamber 3, so that plasma discharge is generated to thereby ignite the mixture within the combustion chamber 3.

摘要： PROBLEM TO BE SOLVED: To detect a knocking occurrence position in a spark ignition internal combustion engine.
SOLUTION: A signal is acquired from a pressure sensor arranged in a plurality of positions in a combustion chamber (S100). Components in frequency band characterizing the knocking is extracted from the signal to obtain a time history indicating change of spectral density of the band in relation to time (S108). A time history of spectral density of each sensor is compared, and difference of time of arrival of pressure wave of each sensor (actual arrival time difference) is calculated (S112). On the other hand, the knocking occurrence position is assumed and difference of time of arrival of pressure wave between sensors (virtual arrival time difference) is calculated from propagation time of pressure wave between the estimated position and a position of each sensor. A position for making difference between actual arrival time and the virtual arrival time difference minimum by changing the estimated knocking occurrence position is made a knocking occurrence position (S114, S116).

摘要： PROBLEM TO BE SOLVED: To efficiently ignite an air-fuel mixture in a combustion chamber with further small energy consumption without complicating a structure.
SOLUTION: When a D.C. voltage is applied between a center electrode 51 and a ground electrode 53, a spark plug 31 can ignite the air-fuel mixture in the combustion chamber 3 by D.C. discharge generated in a gap 52 between a tip 51a of the center electrode 51 and a tip 53a of the ground electrode 53. When electromagnetic waves are radiated toward the inside of the combustion chamber 3 from an electromagnetic wave radiator, the spark plug 31 can ignite the air-fuel mixture in the combustion chamber 3 by plasma discharge generated by locally enhancing electromagnetic intensity of the electromagnetic waves in the combustion chamber 3 in the vicinity of the tip 51a of the center electrode 51 and in the vicinity of the tip 53a of the ground electrode 53. By selectively carrying out either ignition by the plasma discharge or by the D.C. discharge, electric energy consumed in igniting the air-fuel mixture can be reduced.

Since the breakdown is caused by the laser breakdown plasma 26, the spark discharge 32 can be generated between the center electrode 16 and the ground electrode 18 even if the distance between the center electrode 16 and the ground electrode 18 is set long.
