  2. Original - Animated scheme of a four stroke internal combustion engine, Otto principle: #Suction stroke - Air and vaporised fuel are drawn in. #Compression stroke - Fuel vapor and air are compressed and ignited. #Power stroke - Fuel combusts and piston is pushed downwards. #Exhaust stroke - Exhaust is driven out.

    The Daimler Reitwagen used a hot-tube ignition system and the fuel known as Ligroin to become the world's first vehicle powered by an internal combustion engine. It used a four-stroke engine based on Otto's design. The following year, Karl Benz produced a four-stroke engined automobile that is regarded as the first car. [3]

    The smaller engine used less fuel than the 16-cylinder version. A total of 50 C30-7As were built in mid-1984, and delivered to Conrail. They are externally similar to the C30-7, except that they have six tall hood doors per side (in place of eight) and moved front grilles on long hood, also only 4 steps.

  5. Desaxe - Wikipedia

    en.wikipedia.org/wiki/Desaxe

    In a conventional four-stroke engine, each of the strokes (intake, compression, power, exhaust) involves a nominal rotation of 180°, totaling 720° for the complete 4-stroke combustion cycle. A desaxe engine adds to the duration of the two downward strokes (intake and power), and subtracts the same amount from the two upward strokes ...

    en.wikipedia.org/wiki/Two-_and_four-stroke_engines

    The M4+2 engine has a four-stroke piston and a two-stroke piston. The shaft of the four-stroke piston rotates twice as fast as the shaft of the two-stroke piston, and the two-stroke part always runs at half speed. This ensures that both parts work optimally regarding fuel consumption at all times.

    The 4 VD 14,5/12-1 SRW is a water-cooled four-stroke diesel engine with four inline cylinders. The Fuel is injected with a mechanical direct injection system. The bore is 120 mm, the stroke is 145 mm, the displacement is 6560 cm³. The firing order is 1-3-4-2. The standard version of the engine produces 92 kW and has a torque of 422 Nm.

  8. Otto cycle - Wikipedia

    en.wikipedia.org/wiki/Otto_cycle

    The first person to build a working four-stroke engine, a stationary engine using a coal gas-air mixture for fuel (a gas engine), was German engineer Nicolaus Otto. [4] This is why the four-stroke principle today is commonly known as the Otto cycle and four-stroke engines using spark plugs often are called Otto engines.
