Abstract
PURPOSE: To prevent intake and exhaust efficiency from falling, by providing a pair intake valve and exhaust valve on the major axis of the elliptic cross section of a combustion chamber and installing a spark plug for the combustion chamber so that the plug is located on the minor axis of the elliptic cross section apart from its center between both the valves.
CONSTITUTION: A cylinder head 2 is fitted with a pair of intake valve 15 and exhaust valve 16 on the major axis l-l of the cross section of a combustion chamber 10. The combustion chamber 10 is provided with a spark plug 21 on the minor axis s-s of the cross section apart from its center. According to this constitution, the pair of intake valve 15 and exhaust valve 16 can be located near the center of the cross section on its major axis l-l and a passage of cross sectional area A necessary for intake flow and exhaust flow to proceed under less resistance can be secured among the valves 15, 16 and both walls on the major axis of the cross section of the combustion chamber 10. As a result, intake and exhaust efficiency is enhanced to heighten combustion efficiency.
