2. Two-stroke oil - Wikipedia

   en.wikipedia.org/wiki/Two-stroke_oil

   The oil is dyed blue to make it easier to recognize in the gasoline. It appears black in this bottle because it is not diluted. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline -powered ...

3. Two-stroke engine - Wikipedia

   en.wikipedia.org/wiki/Two-stroke_engine

   For the mathematical concept, see Cyclic permutation. 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. A four-stroke engine requires four strokes of the piston to complete a power cycle ...

4. Two-stroke diesel engine - Wikipedia

   en.wikipedia.org/wiki/Two-stroke_diesel_engine

   A two-stroke diesel engine is a diesel engine that uses compression ignition in a two-stroke combustion cycle. It was invented by Hugo Güldner in 1899. [ 1] In compression ignition, air is first compressed and heated; fuel is then injected into the cylinder, causing it to self-ignite. This delivers a power stroke each time the piston rises and ...

5. Rotax 447 - Wikipedia

   en.wikipedia.org/wiki/Rotax_447

   The Rotax 447 features piston-ported, air-cooled cylinder heads and cylinders, utilizing either a fan or free air for cooling. Lubrication is by use of pre-mixed fuel and oil. The engine can be equipped with either one or two piston-type float carburetors. The dual-carburetor version uses Bing model 84 carburetors.

6. Kawasaki triple - Wikipedia

   en.wikipedia.org/wiki/Kawasaki_triple

   Kawasaki triple. The Kawasaki triples were a range of 250 to 750 cc (15 to 46 cu in) motorcycles made by Kawasaki from 1968 to 1980. The engines were air-cooled, three-cylinder, piston-controlled inlet port two-strokes with two exhaust pipes exiting on the right side of the bike, and one on the left. It was the first production street ...

7. Scavenging (engine) - Wikipedia

   en.wikipedia.org/wiki/Scavenging_(engine)

   Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air/fuel mixture (or fresh air, in the case of direct-injection engines) for the next cycle. If scavenging is incomplete, the remaining exhaust gases can cause improper combustion for the next cycle, leading to reduced power ...

8. Two- and four-stroke engines - Wikipedia

   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 same principles apply to having two ...

9. 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.
