The most common type of flat-twin engine is the boxer-twin engine, where both pistons move inwards and outwards at the same time. The flat-twin design was patented by Karl Benz in 1896 and the first production flat-twin engine was used in the Lanchester 8 hp Phaeton car released in 1900. The flat-twin engine was used in several other cars since ...
Animation of a two-stroke engine. A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle.
The first Motorwagen used the Benz 954 cc (58.2 cu in) single-cylinder four-stroke engine with trembler coil ignition. [16] This new engine produced 500 watts (2 ⁄ 3 hp) at 250 rpm in the Patent-Motorwagen, although later tests by the University of Mannheim showed it to be capable of 670 W (0.9 hp) at 400 rpm. It was an extremely light engine ...
1876: Otto applied for a patent on a stratified charge engine that would use the four-stroke principle. The patent was granted in 1876 in Elsass–Lothringen, and transformed into a German Realm Patent in 1877 (DRP 532, 4 August 1877). [17]: p51-52 1879: A prototype two-stroke gas engine is built by German engineer Carl Benz. [23]
In 1879, Karl Benz patented a reliable two-stroke gasoline engine. Later, in 1886, Benz began the first commercial production of motor vehicles with an internal combustion engine, in which a three-wheeled, four-cycle engine and chassis formed a single unit. [14] In 1892, Rudolf Diesel developed the first compressed charge, compression ignition ...
From 1893 to 1900 Benz sold the four wheel, two seat Victoria, [19] a two-passenger automobile with a 2.2 kW (3.0 hp) engine, which could reach the top speed of 18 km/h (11 mph) and had a pivotal front axle operated by a roller-chained tiller for steering. The model was successful with 85 units sold in 1893, and was produced in a four-seated ...

In two-stroke engine technology a Port-map is a diagram which shows the ports that are cut into the cylinder of an engine. A port-map can be useful to determine opening/closing-timing and the area of specific ports.
