Abstract

1307565 Starting HUSQVARNA VAPENFABRIKS AB 11 May 1970 [12 May 1969 24 Nov 1969] 22706/70 Heading F1K In a method of starting an internal-combustion engine 1 by means of gas under high-pressure which is used in at least one of the engine cylinders 3 for driving the engine during starting, the gas pressure is reduced below that of the source and supplied at such reduced pressure to the cylinder at intervals when the piston in the cylinder is in the proximity of the top dead centre position between the compression and expansion stroke. When the valve 9 is opened gas flows to the chamber 7. The valve 8 is opened and gas then flows to the pressure reducing valve 11. A valve 12 situated in the conduit 6 is operated by cam or other member (not shown) driven by the engine and controls the supply of gas to the engine cylinder. In a modification the compressed gas passes to the engine combustion chamber through a passage in the piston. In another modification a spring is tensioned and stores energy expended manually in turning a handle. When a centre member has turned through approximately 90 degrees a latching tooth is moved out of engagement with a toothed sector and a further member is rotated by the spring and an operating movement is transmitted to the valve causing the same to open.
