1879: Karl Benz, working independently, was granted a patent for his internal combustion engine, a reliable TWO-STROKE gas engine, based on Nikolaus Otto's design of the four-stroke engine.

It was Sir Dugald Clark (1854 – 1932) designed the first two-stroke engine in 1878 and patented it in England in 1881.
The two-stroke cycle of an internal combustion engine differs from the more common four-stroke cycle by completing the same four processes (intake, compression, power, exhaust) in only two strokes of the piston rather than four. This is accomplished by using the space below the piston for air intake and compression, thus allowing the chamber above the piston to be used for just the power and exhaust strokes.
