Abstract

467,082. Cylinders. LEUVRAIS, J. Nov. 4, 1935, No. 30414. [Classes 7 (ii) and 7 (iii)] In a compressionignition engine having a very high ratio of compression capable of producing explosion of the fuelair mixture, the fuel is injected substantially before the end of the compression stroke whereby the admission of fuel ceases before commencement of ignition, and an explosion chamber is provided communicating with the upper part of the cylinder through an orifice of varying section, which is sufficiently small, when the piston is close to the end of the compression stroke and explosion takes place, as to deaden the effects of the explosion on the piston and increases subsequently in a gradual manner. Instead of injecting fuel, a fuel-air mixture from a carburetter may be admitted into the cylinder. In the fuel-injection engine shown in Fig. 1, a nozzle 8 injects into a torus-shaped combustion chamber 1 communicating with the clearance space 2 of a cylinder 9 by an orifice, the area of which is varied by means of a conical projection 3 on top of the piston ; a formula for determining the minimum section of the orifice is given. The exhaust passes through a convergentdivergent nozzle 12 in which an air-inlet 6 is provided ; a cam-operated valve 13 may be provided in the exhaust passage. A modification, Fig. 4 (not shown), comprises a four-stroke engine having overhead inlet and exhaust valves and an explosion chamber arranged to one side of the centre line of the engine. In the engine shown in Fig. 7, a valve 21 admits a fuel-air mixture from a carburetter into an. explosion chamber 1. To restrict the passage into the cylinder during the suction stroke, the valve co-operates with the edge 25 of a liner 24. A modification is shown in which the chamber 1 is in the piston.
