January, 1926 ¢ MARINE REVIEW Wortuincton Double-acting Two-cycle Diesel Oil Engine “We're Creepin’ On—We’re Creepin’ On” — “Less Weight and Larger Power” HE words that Kipling put in the mouth of McAndrews, the “dour Scots engineer,” accurately describe the progress of the science of ship propulsion, not merely in steam, but in the use of a more efficient engine which neither Kipling nor McAndrews foresaw,— the Diesel oil engine. But every so often, in human progress, the “creeping” gives place to a leap. Such a leap was taken when the Worthington engineers conceived the original idea which, for the first time, made the two-cycle, double-acting Diesel oil engine a thoroughly reliable and com- mercially successful marine engine. At one stroke the new Worthington design eliminates the weaknesses which have led to so many cracked cylinder-heads, so many cylinder failures; and advances the successful application of Diesel propulsion. Yet back of this apparently spectacular ad- vance was more than twenty years’ experience in the design and construction of internal-com- bustion engines, culminating in three years of careful research and experimental work that left nothing to chance. The Worthington two-cycle double-acting Diesel oil engine is well suited to marine practice by reason of its high economy, lower weight, smaller size per horse-power and lower price.
