It is a kind of internal combustion engine. It uses high-volatility gasoline as fuel. The gasoline engine introduces a mixture of misty gasoline and air into the cylinder, and then uses the electrode spark to burn the mixed gas. The high-temperature and high-pressure gas formed during combustion pushes the piston and reciprocates. movement. The reciprocating motion uses a crank or the like to make the movement turn.
The working process of the Otto internal combustion engine can be divided into four strokes, that is, an intake stroke, a compression stroke, a work (fuel combustion gas expansion and work, also called an explosion stroke) stroke and an exhaust stroke, which are internal combustion engines. a loop. From the condition of the work of the internal combustion engine, the chemical reaction of the combustible gas is its energy source, causing the high temperature of the working fluid; the cylinder piston is its working part; the waste working fluid of the work is discharged into the atmosphere with the atmosphere as its condenser. . Since the temperature at which the combustible mixed gas is burned in the cylinder is high (about 1500 ° C or higher), the efficiency of the internal combustion engine is higher than that of the steam engine. In the Otto internal combustion engine, about 25% of the heat is used as useful work, 10% of the heat is lost in the friction, 25% of the heat is carried away by the exhaust gas, and 40% of the heat is transferred to the cooling water outside the cylinder, so its The efficiency is generally 20 to 30%. The power of the Otto internal combustion engine varies from 367.7 watts (1/2 horsepower) to 1838.8 kW (2500 hp).
