French workers
In 1862, Cheng proposed the principle of four-stroke cycle for manufacturing efficient internal combustion engines.
The realization of the principle was first completed by the German Otto (1832- 189 1), who developed the first four-punch.
Cheng piston internal combustion engine won the patent of 1876, and soon it was exhibited at 1877 Paris Expo.
It has been popularized. Otto's internal combustion engine is a gas engine with a thermal efficiency of 14%. 35 years later,
Has been engaged in the research of internal combustion engine, and later improved the thermal efficiency to more than 20%. So he got it.
The honor of the inventor of internal combustion engine.
1. Invention and development of internal combustion engine
Speaking of the invention of the internal combustion engine, it should be said that first of all, the cannon gave people important enlightenment, and even said
Gun is the embryonic form of internal combustion engine, and famous physics first used the principle of gun to study power machinery.
Huygens. Because the conditions for inventing the internal combustion engine are not yet available, the result is that although the idea of internal combustion engine is booming.
Before the steam turbine, the internal combustion engine was born after the steam engine.
(1) From the advent of gas engines to the success of gasoline engines
18- 19 century, with the development of coal and petroleum industry, the generation of gas and the fractionation of oil make the internal.
The invention of the gas turbine became possible. During the development of gas turbines in 2000, engineers and inventors from many countries.
It has made pioneering contributions to the design and improvement of internal combustion engine, and the first one can be put into practical use.
The internal combustion engine produced is a gas machine with two strokes, no compression and electric ignition, and the credit belongs to the French.
Renault (1821-1900) was successfully manufactured at 1860. Although its thermal efficiency is only 4%, it
After all, it is a new type of heat engine without steam power. Later, with the development of thermodynamic theory, French workers

The honor of the inventor of internal combustion engine.
The internal combustion engine has been continuously improved and perfected in its development process, but its transformation to miniaturization and high speed is
It was realized after the appearance of petroleum fuel, or rather after the use of gasoline as fuel. In Otto
After successfully developing a four-stroke piston internal combustion engine, he founded the German Gas Engine Company.
Division, its collaborator Daimler (1834-1900), a German, switched to steam on the basis of Otto's internal combustion engine.
Using petroleum as fuel, the first modern four-stroke reciprocating gasoline engine was successfully manufactured in 1883.
The key part is the carburetor invented by Daimler, so the engine speed is determined by every minute of the gas engine.
200 rpm quickly increased to 900 rpm. 1889, Daimler manufactured a V-type twin-cylinder gasoline engine.
This car was patented.
