Before the 4 stroke engine was created, first the motorbike engine used 2-stroke engine technology, which sounded very noisy and wasteful of oil, after the 2-stroke era, do you know who created the 4-stroke engine, aka the previous generation’s 2-stroke refinement engine? why is it possible that the 4 stroke engine which until now has been widely used by motorbikes?
The inventor of this internal combustion engine was born on June 14, 1832 in Holzhausen (Germany) named Nicolaus August Otto, more The invention of the 4-stroke engine by otto is based on the invention of the 2-stroke engine that uses natural gas invented by Etiene Lenoir.

This made Otto think that if only he used liquid fuel, the 2-stroke engine would be easy to operate. So Otto made a design for the carburetor and patented it, but the design was rejected by the patent agency, because there was a similar tool that had been designed by someone else. Before discussing further about Otto, we will discuss a little about Otto’s life journey.

Initially otto worked as a salesman selling tea, sugar and coffee, then quit in 1864. Otto was more concerned with his invention, so he began to dream and founded the Engine Manufacturing Company NA & Otto, which was the first company or factory to produce internal combustion engines in German. Otto continued to pursue and perfect Entiene Lenoir’s discoveries. By 1862, Otto had made a new engine model that worked on the basis of four thrusts and had already begun building this type of engine.

Otto had difficulty with the combustion system so that he could move the engine more practically, so he left the 4-stroke engine project and started wanting to perfect the 2-stroke engine that was driven with natural gas, and the result of his hard work was patented in 1863. In the same year he met his partner, a sugar entrepreneur named Eugenne Langen, who paid for all his research and creation. In 1867 the two-speed thrust engine which used natural gas was awarded a medal in the WORD FAIR held in Paris. In 1872, Otto recruited a young engineer named Gottlieb Daimler.

Their collaboration is able to advance the factory that has been established. Furthermore, the Otto engine has been a pioneer in the manufacture of Gottlieb Daimer and Karl Benz cars. The first Daimer car was built to have 6 horsepower, and was sold to the Prince of Wales. Furthermore, the Benzine Buggy car was patented in 1895. Even though he had made a lot of profit from the sale of the 2-stroke engine, it did not make Otto forget his dream of a 4-stroke engine that compressed a mixture of fuel oil and air before combustion occurred which could be the driving force for rotation. In 1876 he had succeeded in creating the first 4-stroke engine model, and the patent was obtained a year later. The 4-stroke engine received a very good response, within 10 years it had sold more than 30,000 machines, this made the Leonir-type engine out of the way.

In 1886, Otto’s invention was challenged by a Frenchman named Alphonse Beau de Rochas, because he had the same idea in 1862. But Alphonse cannot be considered the inventor of the 4 stroke engine because it was never published and marketed, even though it was patented.
Otto got the idea of ​​making a 4-stroke engine from a 2-stroke engine created by Lenoir, so that he didn’t lose his patent rights and the machine he made was still selling well in the market. Otto died in 1891 at the age of 59.
