The working principle of a two-stroke generator: There are three holes in the cylinder block of the engine, namely the intake hole, the exhaust hole and the ventilation hole. These three holes are closed by the piston at a certain time. Its work cycle consists of two strokes:
1. First stroke: The piston moves upward from bottom dead center. After the three air holes are closed at the same time, the mixed gas entering the cylinder is compressed. ; When the combustible mixture flows into the crankcase.
2. Second stroke: When the piston is compressed near top dead center, the spark plug ignites the combustible mixture and the expansion of the gas pushes the piston down to do the work. At this time, the air intake hole is closed and the combustible mixture sealed in the crankcase is compressed; When the piston approaches bottom dead center, the exhaust hole opens and the exhaust gas flows out.catch, then the ventilation hole opens; the pre-pressed combustible mixture rushes into it. The cylinder removes the exhaust gases and carries out the ventilation process.

The so-called four-stroke engine means that every two cycles of the engine crankshaft, it passes through the four stages of intake, compression, power and exhaust. One stroke completes a work cycle, while a two-stroke engine only needs one rotation of the crankshaft and two strokes to complete a work cycle.
From a structural point of view, the structure of a two-stroke engine is relatively simple. It mainly consists of cylinder head, cylinder, piston, piston ring and other parts. intake holes, exhaust holes and ventilation hole; the opening and closing of the air hole is determined by the position of the piston. Compared to four-enginestime, there are no valve mechanisms or complex lubrication systems. The cooling system is generally air-cooled, and the structure is greatly simplified.
From a performance point of view, when the crankshaft speed is the same, the number of times a two-stroke engine does work per unit time is twice that of a two-stroke engine four-stroke. In theory, the power of a two-stroke engine should be twice that of a four-stroke engine (but in fact it is only 1.5-1.7 times). The engine has higher horsepower per liter, better power and relatively low engine vibrations). . Additionally, two-stroke engines are lighter, cheaper to manufacture, have lower failure rates, are more convenient to maintain, and are more practical and flexible to use.
Overall, four-stroke engines are more widely used. The vast majorityMost cars and construction equipment are equipped with four-stroke engines, while two-stroke engines are more commonly used in rarely used and occasional cases. where the “thrust-to-weight ratio” is important. For example, they are widely used on lawn mowers, chain saws, model airplanes, agricultural machinery, etc., as well as some small motorcycles and dirt bikes which pay more attention to power performance. There are also tanks, ships, heavy transport vehicles, etc. These vehicles have high power requirements for the engine and also require the engine to be light and small in size. Two-stroke engines are a good choice.
Method/steps
Step one: Add engine oil.
Whether it is a two-stroke generator or a four-stroke generator, engine oil must be added. The generatorstwo-stroke add mixed oil, which means the engine oil and gasoline are in the same tank. Pay attention to two points when choosing engine oil. The first is to choose a two- or four-stroke engine, and the second is to choose whether antifreeze is needed. add When adding engine oil, be sure to top it up!
Step 2: Add gasoline.
Gasoline generally chooses gasoline above 90, which is universal and can be purchased by ordinary customers at gas stations. Please use high quality gasoline and add at least 30% of the fuel tank volume.
Step 3: If it is an electric start gasoline generator, you must first connect the positive and negative wires of the battery cable. Those with electric start are more convenient if you are worried that the machine won't do it. get off to a good start, especially during the winterr cold, you can consider purchasing an electric start generator, which is more convenient to use! (This step can be skipped for manually started machines).

Step 4: If you want to turn on the generator, first turn off the power switch, open the damper switch and turn on the fuel switch. It must be turned on, otherwise the generator will not start.

Step 5: Start the machine. When starting by hand, first pull the traction rope until there is resistance, then use it to pull quickly. 2 to 3 times in a row. (Electric start gasoline generator, started directly by key).
