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. API-TC - Wikipedia

   en.wikipedia.org/wiki/API-TC

   API-TC. API TC is a certification for two-stroke oils, awarded by the American Petroleum Institute. It is given after the product passes through stringent tests that determine the level of detergent performance, dispersion, and anti-oxidation. It is the only remaining, not revoked classification of the API Two-Cycle motor oil specifications (TA ...

4. Two-stroke engine - Wikipedia

   en.wikipedia.org/wiki/Two-stroke_engine

   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. A four-stroke engine requires four strokes of the piston to complete a power cycle in two crankshaft revolutions.

5. Air–fuel ratio - Wikipedia

   en.wikipedia.org/wiki/Air–fuel_ratio

   Air–fuel equivalence ratio ( λ) Air–fuel equivalence ratio, λ (lambda), is the ratio of actual AFR to stoichiometry for a given mixture. λ = 1.0 is at stoichiometry, rich mixtures λ < 1.0, and lean mixtures λ > 1.0. There is a direct relationship between λ and AFR. To calculate AFR from a given λ, multiply the measured λ by the ...

7. Otto cycle - Wikipedia

   en.wikipedia.org/wiki/Otto_cycle

   The Otto cycle is a description of what happens to a gas as it is subjected to changes of pressure, temperature, volume, addition of heat, and removal of heat. The gas that is subjected to those changes is called the system. The system, in this case, is defined to be the fluid (gas) within the cylinder.

8. Common ethanol fuel mixtures - Wikipedia

   en.wikipedia.org/wiki/Common_ethanol_fuel_mixtures

   Ethanol fuel mixtures have "E" numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E85 is 85% anhydrous ethanol and 15% gasoline. Low-ethanol blends are typically from E5 to E25, although internationally the most common use of the term refers to the E10 blend. Blends of E10 or less are used in more than ...

9. Total-loss oiling system - Wikipedia

   en.wikipedia.org/wiki/Total-loss_oiling_system

   A needle valve adjusts the rate of flow, which may be seen as drops passing through the window beneath the glass reservoir. A total-loss oiling system is an engine lubrication system whereby oil is introduced into the engine and then either burned or ejected overboard. Now rare in four-stroke engines, total loss oiling is still used in many two ...
