Benz Finishes Making his Two-Stroke Gas Engine
To get more revenues, in 1878 he began to work on new patents.
First, he concentrated all his efforts on creating a reliable gas two-stroke engine. Benz finished his two-stroke engine on December 31, 1878, New Year's Eve, and was granted a patent for it in 1879.
Karl Benz showed his real genius, however, through his successive inventions registered while designing what would become the production standard for his two-stroke engine. Benz soon patented the speed regulation system, the ignition using sparks with battery, the spark plug, the carburetor, the clutch, the gear shift, and the water radiator.
Karl Friedrich Benz was born in 1844 in Baden Muehlburg, Germany (now part of Karlsruhe). He was the son of an engine driver. Benz attended the Karlsruhe grammar school and later the Karlsruhe Polytechnic University. In 1871, He founded his first company with partner August Ritter, the "Iron Foundry and Machine Shop" a supplier of building materials.
Benz began his work on a two-stroke engine, in hopes of finding a new income. He received his first patent in 1879. In 1883, he founded Benz & Company to produce industrial engines in Mannheim, Germany. He then began designing a "motor carriage", with a four-stroke engine (based on Nicolaus Otto's patent). Benz designed his engine (958cc, 0.75hp) and the body for the three-wheel vehicle with an electric ignition, differential gears, and water-cooling. The car was first driven in Mannheim in 1885. On January 29, 1886, he was granted a patent for his gas-fueled automobile (DRP 37435) and in July, he began selling his automobile to the public.
