Abstract

2249. Fasey, W. R., Galley, G. T., and Tufnell, G. Feb. 11. Driving - gear.-In two- and four-stroke-cycle engines using cam driving-mechanism, the length of the piston stroke remains constant, and the phases of the cycle occur during unequal angular movement of the cylinders or driving-shaft. In a four-stroke-cycle engine, having a cam-track as shown in Fig. 4, the expansion stroke occurs while the cam roller travels from f to f<1>. The piston dwells from f<1> to e', the exhaust valve being open and remaining open until the end of the exhaust stroke at e<2>. The piston also dwells from e<2> to s and finishes its suction stroke at s<1>. Further piston dwells occur before and after the compression stroke, which corresponds to the inclined portion of the groove between the positions s<1> c. In the construction shown in Fig. 5, the working and suction strokes correspond to the positions f<3>, f<4> and c<3>, s<2> respectively, the exhaust and compression strokes extending over the longer periods corresponding respectively to the positions f<4>, c<3> and s', f<3>. More than one cycle may occur during each revolution of the driving-shaft or cylinders. By the use of a cam such as is shown in Fig. 6, a complete four-stroke, cycle may extend over two complete revolutions. A similar can may be used when working on a two-stroke cycle. The cams . may have double track, and the grooves may be replaced by ribs. The cylinders may be arranged on one or both sides of the cam and parallel to the driving-shaft.
