valerie taylor on 06 Feb 13"The four-stroke cycle (or Otto cycle) of an internal combustion engine is the cycle most commonly used for automotive and industrial purposes today (cars and trucks, generators, etc). It was conceptualized by the French engineer, Alphonse Beau de Rochas in 1862, and independently, by the German engineer Nikolaus Otto [[1]] in 1876."
