from Fig. 51 that the force F actingon the piston varies very greatly during the complete cycle.To remedy this it is possible to have two cylinders acting onthe same crank-shaft and to put the cranks at an angleof 180° to one another. This means that while the firstengine is on its explosion stroke… … 0 180 360° 540° 720 Fig. 52.—Same as Fig. 51, but with Four Cylinders. (Cranks at 180°.) cylinders so that there is an explosion in every half revolutionand the net value of F is as shown in Fig. 52. Even this curveis very saw-toothed, but it gives a steadier forward effort onthe crank-pin than…
