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.

The M4+2 engine, also known as the double-piston internal combustion engine, is a type of internal combustion engine invented by Polish patent holder Piotr Mężyk. [1] The M4+2 engine took its name from a combination of two-stroke engines and four-stroke engines. The two-stroke combustion engine is characterized by a simple construction and ...
A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The valves in a typical four-stroke engine allow the air/fuel mixture into the cylinder at the beginning of the cycle and exhaust spent gases at the end of the cycle. In a conventional ...

Conventionally, a four-stroke (petrol or gasoline) Otto cycle engine is fueled by drawing a mixture of air and fuel into the combustion chamber during the intake stroke. This produces a homogeneous charge: a homogeneous mixture of air and fuel, which is ignited by a spark plug at a predetermined moment near the top of the compression stroke .
