Yangzhou gasoline internal combustion

The work of the internal combustion engine can be divided into four-stroke to carry out, or suction stroke, compression stroke, acting (fuel combustion gas expansion work is done, also known outbreak of the stroke) stroke and exhaust stroke, the four-stroke internal combustion engine is a cycle. From the internal combustion engine acting terms, the chemical reaction of combustible gases is its energy, resulting in the high temperature refrigerant; cylinder piston is part of its work; made a successful waste refrigerant discharged into the atmosphere to the atmosphere as its condenser . Because the combustible gas mixture combustion in the cylinder when the temperature generated is high (above about 1500 ℃), so the efficiency of internal combustion engine than the steam engine's efficiency.

Internal combustion engine at work, about 25% of calories as a useful work, 10% of heat loss in friction, 25% of the heat away from the exhaust, 40% of the heat to the cooling water outside the cylinder, so its efficiency is usually in the 20 ~ 30%. Engine power sizes, small, about 367.7 watts (1 / 2 horsepower), a large can to 1838.8 kilowatts (2,500 horsepower).

      A small moped engine, is a gasoline engine, mainly for bicycle. Characterized by machine followed by the spark plug from top to bottom, with horizontal heat sink cylinder head, into the exhaust port and the next big small big top heat sink cylinder body, so its convolution box assembly, the increase in the number of teeth size of the change gear and the cover, clutch cam and pole, the relocation of the sprocket sleeve cover and sprocket and tighten the loop and processing Housing box and so constitute the magnetic motor. Compact structure, small size, light weight, power, climbing ability, thermal efficiency is good, not up cylinder, simple manufacturing process, saving raw materials, chain not easy to wear and so on.
