Two-stroke or air-cooled four-stroke gasoline engine which has more horsepower
Jul 01,2022
The two-stroke has high horsepower, one working cycle of the crankshaft, high speed and strong continuity of power. Although the two-stroke engine only needs two steps to complete the entire working process, although the speed is high, it can do both the compression stroke and the suction stroke at the same time, the power stroke and the exhaust stroke are completed at the same time. In this way, it is easy to burn insufficiently, the efficiency is low, and it will also cause pollution to the environment. Disadvantages Emissions pollute the environment.
The so-called air-cooled four-stroke gasoline engine means that every two-week rotation of the engine crankshaft completes a working cycle through four strokes of intake, compression, power, and exhaust, while a two-stroke engine only requires one rotation of the crankshaft and two strokes. One work cycle can be completed.
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, and there are intake holes, exhaust holes and ventilation holes on the cylinder block; the opening of the air holes and closing is determined by the position of the piston. Compared with the air-cooled four-stroke gasoline engine, there is no complicated valve mechanism and lubrication system, and the cooling system is generally air-cooled, and the structure is greatly simplified.
