Abstract

969,232. I.C. engine combustion chambers; rotary piston I.C. engines. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. April 26, 1961 [April 27, 1960], No. 15042/61. Headings F1B and F1F. In a compression-ignition engine the combustion chamber 1, Fig. 1, is separate from the working chamber 3 of the engine and is connected thereto by one or several tangential transfer ducts 2 producing a vortex in the combustion chamber which receives at least 40% of the combustion air towards the end of the compression stroke, the combustion chamber having, in the region of the axis of the air vortex core, one or several auxiliary ducts 8, 9, Fig. 2, communicating with the working chamber and independent of the transfer ducts. Compression air from cylinder 3 flows tangentially through duct 2 into combustion chamber 1 to create a vortex into which fuel is injected from an injector 4. After ignition the lighter constituents of the burning gases are forced towards the axis 6 of the vortex core 7 from where they are led by auxiliary ducts 8, 9 to cylinder 3. In another embodiment, the combustion chamber 23, Fig. 3, is arranged in a piston 11 with one or more tangential main ducts 13, 14 and an auxiliary duct 20. The ratio between the overall press-section of ducts 13, 14 and auxiliary duct 20 is about 1À5:1. The ducts 13, 14 may be of tapered or arcuate or spiral form. The fuel may be injected directly into the air or applied to the combustion chamber walls and either of the main ducts or a separate piston opening may serve as a fuel jet passage. The combustion chamber may be used in a rotary piston engine, the auxiliary jet being provided in a housing wall.
