Abstract
PURPOSE: To extend the period of flow of gas intriduced as spiral vortex from an air-fuel mixture storage chamber to a combustion chamber and thus enhance the combustion property by providing the air-fuel mixture storage chamber on the cylinder head and also providing this storage chamber with a valve which is held open for a longer period than in the prior art.
CONSTITUTION: A storage chamber 17 having an on-off valve 13 is provided on a cylinder head 3 above a combustion chamber 4. The storage chamber 17 is communicated with the upstream side of a throttle valve 20 within an intake passage 7 through a duct 18 provided with a check valve 21 permitting only flow into the chamber 17. When a negative pressure is produced in the chamber 17, air is withdrawn from a duct 18. The on-off valve 13 is held open during the intake stroke and is closed at a predetermined crank angle immediately before the ignition. During the open period of the on-off valve high pressure air-fuel mixture that has been temporarily stored is permitted to issue as spiral vortex into the combustion chamber 4.
