Abstract
PURPOSE:To improve charging efficiency of an engine and increase its output, by providing a gas fuel valve independently of intake valves, both feeding high pressure gas to the gas fuel valve and opening the gas fuel valve at about the final period in open timing of the intake valves thus increasing a quantity of air in a combustion chamber. CONSTITUTION:Intake valves 20, 22 are arranged to one side of an engine, while a gas fuel valve 24 and exhaust valve 26 are arranged similarly to the other side. An intake passage 28 of each cylinder is formed with the downstream side to branches and communicated to each intake valve, further the upstream side is opened to the inside of an intake box 30. Then the gas fuel valve 24 is parallelly arranged to the exhaust valve 26 and opened and closed by an overhead cam shaft 38 for driving the exhaust valve 26. That is, said cam shaft 38 is formed with a cam 42 for driving said valve 24, and this cam 42 is operated in such a manner that the valve 24 begins to open at about the final period of open timing of the intake valves 20, 22 further closes earlier than ignition timing. In this way, high pressure gas fuel, fed to said valve 24 from a fuel passage 46, is forcibly fed into a combustion chamber filled with air.
