Daimler & Maybach Build the First Internal Combustion Engine, the "Standuhr"

In 1885 German engineer, industrial designer and industrialist Gottlieb Daimler invented the internal combustion engine, and with his business partner the engine designer and industrialist  Wilhelm Maybach fitted this to a two-wheeler— the first internal combustion motorcycle. In 1886 Daimler and Maybach fitted the engine to a stagecoach, and a boat. Daimler baptized it the Grandfather Clock engine (Standuhr) because of its resemblance to an old pendulum clock. 

The Grandfather Clock engine featured:

• single vertical cylinder
• air cooling
• large cast-iron flywheel
• revolutionary hot tube ignition (Patent 28022)
• exhaust valve controlled by a camshaft allowing high speeds
• a speed of 600 rpm, when at the time most engines could only achieve about 120 to 180 rpm.

 Also 1885 Daimler and Maybach built the first carburetor, which mixed evaporated gasoline with air to allow its efficient use as fuel. It was used that year on a larger but still compact version of the engine, now with a vertical cylinder, that featured:

• 1 Horsepower at 600 rpm output
• 100 cc engine displacement
• non cooled insulated cylinder with unregulated hot-tube ignition (patent DRP-28-022)
