How to Operate Chainsaw

In this video #selambensultanoglu I explained 2-stroke engines and (2T) two-stroke engine oils. I hope you like it and enjoy it. I have compiled the following information in your resignation.
2T Engine:
In these engines, when the piston moves up and down four times, one cycle of an engine is completed. Until this is completed, the crankshaft will take two full turns.
These engines, as the name implies, complete a lap with the up and down movement of the piston twice. At the end of this, the crank would have made a full turn. Unlike the four-stroke engine, the two-stroke engine does the job in two times, not four.
As is known, in four-stroke engines, the suction, compression, burning and exhaust times are separate times, these are the four times mentioned. In two-stroke engines, suction and compression occur simultaneously, both combustion and exhaust simultaneously. In other words, while suction and compression are together in a time, then combustion and exhaust times occur together in one time.
2T Engine Oil:
► What is the Purpose of Lubrication?
The purpose of lubrication is to reduce friction by separating the two surfaces from each other, to facilitate movement by lubricating the surfaces, to prevent corrosion and oxidation by forming a film on the surfaces and to prevent oil-fuel mixture in the engine.
Engine oil is used for lubricating important components, reducing wear, cooling the engine and clutch.
Critical areas where engine oil is applied and used are piston assembly, bearings, bearings and gearbox and clutch that require both lubrication and cooling.
► Oil Bases
Mineral Oils:
Mineral oils are classic oils that have been used for years. They are produced by adding some detergent, viscosity enhancer and anti-wear additives after distillation of the oil we know underground. Their prices are generally cheap and offer an average performance.
Synthetic Oils:
Synthetic oils are oils produced by chemists as a result of various chemical processes in laboratories. Prices are more expensive than mineral oils, but they offer better performance and longer use. Their thermal resistance is high. They perform their lubrication tasks longer and can withstand much more heat.
Semi Synthetic Oils:
Semi-synthetic oils are a mixture of these two, and both their prices and the performance they offer are between these two oils. They are usually obtained by mixing 20-30% synthetic oil into 70-80% mineral oil.
► Engine Oils:
The oils obtained from crude oil are called mineral oil or machine oil. Such oils are not suitable for the operating conditions of the engine. Required properties of engine oils are obtained with additives mixed with mineral oil. The additives add to the oil are the features.
a) It prevents the engine oil from getting too thick at low temperatures and makes the engine easy to work in cold weather.
b) It ensures that the lubricating feature of engine oil at high temperatures is not lost. Thus, residual substances (soot, oily soot) formed on very hot parts such as pistons, piston rings, valves, etc. are minimized. By preventing water, ash, carbon and other chemical substances formed as a result of combustion at work time from forming acid in the oil, engine parts are long-lasting. It provides.
c) It prevents the foaming of the engine oil and improves the quality of the lubrication.
► Engine Oil Duties:
a) Minimizes friction. It creates an oil film between the parts working in contact with each other and minimizes wear and temperature due to friction.
b) Prevents engine compression from falling. The oil, which is removed from the rings from the surface of the cylinder, runs between the ring and its seat and acts as a liquid seal against compression leakage. It minimizes the escape of the compression to the sump between the piston, piston ring and cylinder.
c) Helps to cool down engine parts. The oil in the crankcase is cooler than the engine parts. It brings the temperature taken over the parts to the crankcase during lubrication and cools the parts to a small extent.
d) Cleans engine parts. Engine oil brings the shavings due to wear on the parts it lubricates and the institutions formed as a result of combustion into the crankcase. Thus, it ensures that the engine parts are kept clean constantly.
