There are two main types of two-stroke oil: mineral-based and synthetic-based. Mineral-based oils are made from petroleum, while synthetic-based oils are made from man-made materials. Synthetic-based oils offer better lubrication and protection than mineral-based oils, but they are also more expensive.
The amount of oil that is mixed with the fuel will vary depending on the engine manufacturer's recommendations. Typically, the ratio of oil to fuel is between 1:20 and 1:50.
Here is a more detailed explanation of how two-stroke engines are lubricated:
1. The oil is mixed with the fuel in the fuel tank.
2. The fuel mixture is pumped into the engine by the fuel pump.
3. The fuel mixture passes through the carburetor, where it is mixed with air to form a combustible mixture.
4. The combustible mixture is drawn into the engine cylinder by the piston.
5. The piston compresses the combustible mixture.
6. The spark plug ignites the combustible mixture, causing it to expand and drive the piston down.
7. The exhaust valve opens and the combustion gases are expelled from the engine.
8. The piston moves back up the cylinder, expelling any remaining combustion gases and drawing in a fresh charge of fuel mixture.
The fresh charge of fuel mixture lubricates the moving parts of the engine as it passes through the engine. The oil helps to reduce friction and wear, and also helps to seal the piston rings.
