OTTO - Father of compression engines

Nikolaus August Otto (1832 - 1891), German by nationality  ,  was a travelling salesman and got interested in the Lenoir engine. The Lenoir atmospheric engine ran at 4% efficiency and Otto was contemplating to improve the engine. He , along with Carl Eugen Langen formed the company, NA Otto & Cie to manufacture these engines. This was probably the first engine manufacturing factory in the world.

In 1867, they developed the Otto-Langen atmospheric engine which won many awards and contracts.

The 1867 Otto-Langen atmospheric engine -

This engine could produce power in the range of 0.25 HP to 3 HP. The exploding combustion of the gas lifted the piston, creating a partial vacuum  The piston is returned back to its position by gravity, in the process doing work. The limitation of this engine to go beyond 3 HP was due to the design which requires headroom for this engine. Watch a video of of the Otto-Langen engine working -  (Click Here)

In 1869, they moved the company to the town of Deutz and renamed their company as Gasmotoren - Fabrik Deutz.

In 1872, the management brought in Gottileb Daimler as the factory manager and Wilhelm Maybach as the design director.

Nikolaus Otto and Eugen Langen continued to work in trying to improve the efficiency of the atmospheric engine. In 1876 , they developed the first successful 4-cylinder , compression engine, running on illuminating gas (coal gas). The thermodynamic cycle came to be known as Otto cycle and the engine "Gas Engine". Later on the engine was modified to run on Petrol (gasoline) but the name "Gas Engine" stuck on and even now Petrol engines are referred as Gas Engines.

The Otto Cycle - also referred to as the Constant Volume cycle -

Nikolaus Otto wanted to concentrate on large stationary engines where as Gottileb Daimler wanted to concentrate on small automobile engines. This led to Gottileb Daimler quitting the company in 1882, taking Wilhelm Maybach along with him to form his own company - Daimler AG as we know today.

In 1886 , Nikolaus Otto lost his patent right of the Otto engine over recently discovered 1862 patent of Alphonse Beau de Rochas. This engine design was similar to Nikolaus Otto's design but was only on paper. This led to many companies manufacturing Otto cycle engines.

During the war , the company was renamed as Klockner Humbolt Duetz AG (KHD) and later as Deutz AG.

Some the well known Automotive legends have worked in Deutz AG before moving out and starting their own companies - Gottileb Daimler, Wilhelm Maybach, Prosper L'Orange, Rudolf Diesel, Robert Bosch, Ettore Bugatti.

DAIMLER - Pioneer on Internal combustion engines

Gottileb Daimler (1834-1900), Germany , was a pioneer in the development of internal combustion engine and automobiles. He , along with Wihelm Maybach (later luxury car manufacturer), worked in Deutz,  the engine development company of Nicolaus Otto, the inventor of the Otto cycle and Petrol engine. Both Daimler and Maybach left Deutz in 1880 after differences with Otto.

In the year 1885 , Daimler fitted a small engine on to a wooden framed motorcycle called "Riding Car"  and Maybach drove the "automobile" for a few miles at a maximum speed of 7 mph. Later on they fitted bigger engines to stagecoaches and thus began the automotive era.

After the death of Daimler in 1900, businessman Emil Jellinek entered in to discussions with the company to design and develop new engines for racing purposes and called it by his 10 year old daughter's name , Mercedes and thus born the Mercedes brand.

The Daimler logo - three point star - signifies dominance in Land, water & air. The word Mercedes added later on

In the year 1926 , Daimler and Benz & Cie merged to form the company Daimler Benz - the three point star of Daimler surrounded by the laurels of Benz.

 

 In 1998 , Daimler Benz acquired Chrysler corporation and renamed itself as DaimlerChrysler and in 2007 , it divested Chrysler to become Daimler AG
