摘要： PROBLEM TO BE SOLVED: To provide a spark ignition internal combustion engine capable of increasing the combustion speed of an air-fuel mixture formed in a cylinder.
SOLUTION: The spark ignition internal combustion engine is provided with an ignition plug 1 disposed at the upper part of the cylinder. At the ignition timing, two tumble streams 3a, 3b swirling in opposite directions to each other are formed in the cylinder, and two tumble streams ascend along the approximately opposed positions of a cylinder bore, collide with each other near the position of the ignition plug at the upper part of the cylinder and descend adjoining each other toward the center part in the cylinder. An arc A generated in an ignition gap 1a of the ignition plug by one or both of the two tumble stream at this time is extended to the center part of the air-fuel mixture formed in the cylinder.

摘要： PROBLEM TO BE SOLVED: To prevent generation of knock and to improve output torque and fuel consumption.
SOLUTION: In a combustion chamber structure of an internal combustion engine where an ignition plug 15 is located substantially at the center of a combustion chamber 10, an intake-side squish area 53 for producing a squish effect is formed between an intake-side top face 5 of a piston 1 and an intake-side wall surface 11b of a cylinder head 8 opposing thereto, and an exhaust-side squish area 52 for producing a squish effect is formed between an exhaust-side top face 5 of the piston 1 and an exhaust-side wall surface 11a of the cylinder head opposing thereto. The exhaust-side squish area 52 is so formed that it is harder to obtain the squish effect in the exhaust-side squish area 52 than in the intake-side squish area 53.
