Abstract

PURPOSE: To enhance thermal efficiency of an internal combustion engine and to improve in the durability of and the sealing effect of valves, by providing a main valve serving as both an intake valve and an exhaust valve in a cylinder head and by providing a sub-valve selectively communicating to an intake pipe and an exhaust pipe.
CONSTITUTION: A main valve 10 and a sub-valve 11 are disposed in a cylinder head so that the sub-valve 11 opens to an exhaust pipe before the initiation of exhaust cycle, then the main valve 10 opens for discharging exhaust gas, and thereafter the sub-valve 11 closes to the exhaust pipe and opens to intake pipe to complete the exhaust cycle and to make ready to initiate the next intake cycle. Due to the arrangement in which the intake cycle is completed by closing the main valve 10, the area of valve passage is greatly increased, causing loss in tintake or exhaust to be reduce, so as to enhance thermal efficiency of the engine. Further, since the main valve is exposed to exhaust gas and purging air, alternately, the sealing effect of and the durability of the main valve are greately improved.
