Abstract
PURPOSE: To prevent occurrence of local heating in top surfaces of a piston, by forming communication holes communicating main and sub-combustion chambers with main and sub-communication holes and constituting an opening part of the sub- communication hole to the main combustion chamber so that combustion gas from the main communication hole may be blown to the transversely spreading direction.
CONSTITUTION: A sub-combustion chamber 5 is provided in a cylinder head 2 and communicated to a main combustion chamber 4 through a main communication hole 9, and the main communication hole 9 is tangentially provided for the sub-combustion chamber 5. A flat almost heart-shaped cavity 10 is hollowly provided on top surfaces of a piston 3, and to this cavity 10 a groove 11 is successively provided correspondingly to a lower position of the main communication hole 9. Further a sub- communication hole 14 is formed to be opened to a suitable place in the sub-combustion chamber 5, and an opening part 14a of this sub-communication hole 14 to the main combustion chamber 4 is almost right angularly opened to the top surface of the piston 3 in an area between said groove 11 and a recessed part 12 of the cavity 10. In this way, jetted gas to the main combustion chamber 4 can be transversely spread.
