PURPOSE:To intensify swirl yielded in a combustion chamber and to improve combustion efficiency, by a method wherein a timing detecting means for detecting the terminal of fuel injection is mounted, and an air flow is created in a combustion chamber through actuation of means for creating an air flow according to the output thereof. CONSTITUTION:When an engine is shifted to high-rotation high-load operation, a first valve 36 is opened by means of the output of a circuit for detecting said operation, forced oil from an oil pump 30 flows in a flow-in chamber 27 of an actuator 15, and flows in a reservoir chamber 28 through a one-way valve 22. In which case, with a second valve 36 simultaneously closed, the forced oil is confined to the interior of the reservoir chamber 28, and an engaging cylinder 19 and a spherical fulcrum 14 are locked to rise position. In this case, when a drive arm 12 is pushed down by a timing cam 13 in response to timing of fuel injection terminal, swing of the arm 12 pushes down a plunger 11a of an air injection pump 11 to inject the air through an injection nozzle 16, resulting in intensification of swirl yielded in a combustion chamber 5. |
