2. Two-stroke engine - Wikipedia

   en.wikipedia.org/wiki/Two-stroke_engine

   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.

3. Premixed flame - Wikipedia

   en.wikipedia.org/wiki/Premixed_flame

   A premixed flame is a flame formed under certain conditions during the combustion of a premixed charge (also called pre-mixture) of fuel and oxidiser. Since the fuel and oxidiser—the key chemical reactants of combustion—are available throughout a homogeneous stoichiometric premixed charge, the combustion process once initiated sustains ...

4. Homogeneous charge compression ignition - Wikipedia

   en.wikipedia.org/wiki/Homogeneous_charge...

   The engine operates in HCCI mode at speeds below 60 miles per hour (97 km/h) or when cruising, switching to conventional SI when the throttle is opened and produces fuel economy of 43 miles per imperial gallon (6.6 L/100 km; 36 mpg ‑US) and carbon dioxide emissions of about 150 grams per kilometre, improving on the 37 miles per imperial ...

5. Four-stroking - Wikipedia

   en.wikipedia.org/wiki/Four-stroking

   Four-stroking is a condition of two-stroke engines where combustion occurs every four strokes or more, rather than every two. Though normal in some instances at idle, extremely high engine speeds, and when letting off the throttle, such firing is uneven, noisy and may, in cases of malfunction, damage the engine if allowed to continue unabated.

6. 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.

7. Spark-ignition engine - Wikipedia

   en.wikipedia.org/wiki/Spark-ignition_engine

   Spark-ignition engines are commonly referred to as "gasoline engines" in North America, and "petrol engines" in Britain and the rest of the world. [1] Spark-ignition engines can (and increasingly are) run on fuels other than petrol/gasoline, such as autogas (), methanol, ethanol, bioethanol, compressed natural gas (CNG), hydrogen, and (in drag racing) nitromethane.

9. Premixed turbulent flames - Wikipedia

   en.wikipedia.org/wiki/Premixed_turbulent_flames

   The deposition of energy from the spark generates a flame kernel that grows at first by laminar, then by turbulent flame propagation. And in which the oxidizer has been mixed with the fuel before it reaches the flame front. This creates a thin flame front as all of the reactants are readily available.
