Nicolaus August Otto was an engineer that invented the first practical alternative to the steam engine. He was born in Holzhausen, Germany. He had built his first gas engine in 1861. Then, in partnership with a German industrialist Eugen Langen, they had improved the steam engine and won a gold medal. They had won the award in Paris Exposition of 1867.
Nicolaus August Otto had became an salesman in 1876. He had found an newspaper account of the Lenoir internal combustion engine. That same year he had made the four-stroke piston cycle. It is called 'Otto cycle' in his honor. The engine called for four strokes of a piston. It was designed to draw in and compress a gas-air mixture in the cylinder, then an internal explosion.
Since Otto's engines reliability, efficiency, and relative quietness, more than 30,000 Otto cycle engines were built in the next 10 years.
Otto was also the First biker.

Otto was a salesman with a grocer. When he had read an article of Lenoir's two-stroke gas-engine internal combustion engine. Otto started a workshop near a workshop in Deutz near Cologne, supported by Langen in 1863. He had made a model engine and improved the gas engine.
Otto Four Stroke Engine worked like this.
INTAKE STOKE ÃÂ· First is the intake stroke. The intake valve would open and let the mixture of gas and air in. The exhaust valve is shut during this stroke. The piston would be moving down towards the crankcase.
COMPRESSION STROKE ÃÂ· Second is the compression stroke. Both the intake and exhaust valve would be closed. The piston would be moving up towards the cylinder head.
POWER STROKE ÃÂ· After the compression stroke is the power stroke. During this stroke both the intake and exhaust valve are closed. The piston is moving up towards the cylinder head. When the piston reaches top dead center (TDC) the spark is ignited.
EXHAUST STROKE ÃÂ· Last is the exhaust stroke. The intake valve is closed and the exhaust valve is open letting the expelled gases out.
Above is the four-stroke engine. It shows all the parts and which way the piston is moving.
Did Otto Sell A Lot Of Engines? He had sold a lot of engines. He had changed how we would make some cars today. We use these engines in BMW and other high expensive cars. A lot of people had bought he's engine. Over 30,000 engines were sold the year it was built and out to the world.
Otto family was farmers and that is all that I could find out about them.
