Abstract

PURPOSE: To fasten the flow velocity of a gas mixture during a low-speed and light- load operation of an engine and to increase the output of the engine, by providing two intake valves with each combustion chamber of the engine abd a mechanism adapted to deactuate one of the valves when the engine is in the low-speed and light-load operation.
CONSTITUTION: A combustion chamber 8 is provided with two intake valves 14, 16 and an exhaust valve 18. The intake valve 14 is in contact with a first cam 22 of a cam shaft 20 via a first rocker arm 26 while the intake valve 16 is in abutment with a second cam 24 of the same cam shaft 20 via a second rocker arm 38. A plunger (not shown) is disposed in a casing 32 of the first rocker arm 26, which plunger moves downwardly by an oil pressure introduced through the shaft 28 to deactuate the intake valve 14. The shaft 28 includes a control mechanism 98 permitting an entry of oil thereinto. The mechanism 98 is provided with a solenoid valve 108 which is excited upon detection of any low-speed and light-load operation of the engine to communicate passages 102, 104 to each other.
