Dugald Clark

Dugald Clark (1854–1932) designed the first two-stroke engine in 1878 and patented it in England in 1881. He received a knighthood for his work and became Sir Dugald Clark.

Clark's engine

Clark's engine is not the common two-stroke that is used regularly today. It was much more complicated than the modern two-stroke. It used valves, like a four-stroke, and a compressor to blow a mixture of air and diesel fuel into the cylinders. These engines were used mainly in ships and locomotives and were much larger than the modern design. In the United States they were adopted by General Motors, resulting in the formation of the Detroit Diesel Company.
