Abstract

192,693. Durand, E. H. M. E. Feb. 2, 1922, [Convention date]. Regulating.-Two or four stroke engines are constructed so that they can function with two additional strokes to the cycle, whereby, in the case of aircraft engines for example, reduction in atmospheric pressure is compensated for. The two extra strokes are used to draw in a supplementary charge and compress it into a reservoir, from which it is admitted to the cylinder as an extra charge at the end of the normal suction stroke; or the supplementary charge may be compressed directly into another cylinder working at about one stroke in advance. In the case of a fourstroke engine, there may be four additional strokes permitting two supplementary charges. The four-stroke engine described comprises a number of cylinders which is a prime number with respect to the numbers 2 and 3, and is provided with two overhead cam shafts g, h, the latter of which rotates at half-speed and is used for the four-stroke cycle, whereas the former rotates at one-third speed and is used for the six-stroke cycle. Each cylinder has a normal inlet valve d actuated by a lever d', two exhaust valves e actuated by a forked lever e<1>, and a supplementary valve f which is actuated by a lever f<1> and controls the delivery and compression of the supplementary charge and its re-introduction at the end of the normal suction stroke. The levers d<1>, e<1>, f<1> are pivoted on a shaft j which is eccentrically mounted so that it can be moved to bring the levers into engagement with either of the cam shafts, by means of a lever j<2>. Ignition timing devices on one end of the cam shafts are so arranged that, when the shaft j is adjusted, the ignition current which is not required is conveyed to earth. Turbo-compressors or other compression devices may be used in addition, for compensating for rarefaction of the atmosphere.
