Month in the Patent Office To produce equal firing intervals in a fourstroke engine comprising x rows of y radiallyarranged cylinders, the crank shaft has y throws which are not symmetrically arranged, but are angularly spaced or a multiple thereof, excepting or a multiple thereof, y being an odd number, and x and y being both greater than 2. Formul are given for ascertaining for different firing orders, the arrangement of crankshaft throws, and of balance weights at opposite ends of the crankshaft and the masses thereof, calculations being effected for a 27 cylinder engine arranged in nine rows of 3 each in this case the front and rear throws are spaced equally from the third throw. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Aircraft Engineering and Aerospace Technology Emerald Publishing

Abstract

To produce equal firing intervals in a fourstroke engine comprising x rows of y radiallyarranged cylinders, the crank shaft has y throws which are not symmetrically arranged, but are angularly spaced or a multiple thereof, excepting or a multiple thereof, y being an odd number, and x and y being both greater than 2. Formul are given for ascertaining for different firing orders, the arrangement of crankshaft throws, and of balance weights at opposite ends of the crankshaft and the masses thereof, calculations being effected for a 27 cylinder engine arranged in nine rows of 3 each in this case the front and rear throws are spaced equally from the third throw.
