The difference between two-stroke and four-stroke

The so-called four-stroke engine means that every two revolutions of the engine crankshaft, it goes through four strokes of intake, compression, work, and exhaust to complete a working cycle, while a two-stroke engine only needs one revolution of the crankshaft and two strokes to complete a work cycle. A working cycle.

From the structural point of view, the structure of the two-stroke engine is relatively simple, mainly composed of cylinder head, cylinder, piston, piston ring and other parts. The cylinder block is provided with intake holes, exhaust holes and ventilation holes; the opening of the air holes And closing is determined by the position of the piston. Compared with the four-stroke engine, there is no complicated valve mechanism and lubrication system, and the cooling system generally adopts air cooling, which is greatly simplified in structure.

From the performance point of view, when the crankshaft speed is the same, the number of work per unit time of a two-stroke engine is twice that of a four-stroke engine. In theory, the power of a two-stroke engine should be twice that of a four-stroke engine (but in fact it is only 1.5 to 1.7 times), the engine has a higher power per liter, better dynamics, and lower engine vibration. In addition, the two-stroke engine is lighter in weight, low in manufacturing cost, lower in failure rate, easier to maintain, and more convenient and flexible to use.

On the whole, four-stroke engines are more widely used. Most automobiles and construction machinery are equipped with four-stroke engines, while two-stroke engines are more commonly used in those that are not frequently used and the "thrust-to-weight ratio" is very important. occasion. For example, lawnmowers, chain saws, model airplanes, agricultural machinery, etc., are also widely used on some small motorcycles and off-road motorcycles that pay more attention to power performance. There are also tanks, ships, heavy-duty transportation vehicles, etc. These models have high requirements on the power of the engine, but also require the engine to be light in weight and small in size.

Two-stroke engines are a good choice.

How to store the engine normally

Be sure to store the engine upright, not upside down, otherwise it may cause damage to the engine.

Storage and transportation

Gasoline is easy to oxidize and deteriorate during storage. Use of deteriorated gasoline will block the oil circuit and cause difficulty in starting. If you do not use the engine for more than half a month, please empty the fuel in advance. Check the oil condition of the four-stroke engine for 5 hours the first time, and then check the oil and air filter before each use. When the machine is stored and transported, the engine must be placed horizontally to avoid fuel and oil leakage.
