             Diescher was born in Paris, France in 1856, and his parents were German immigrants. After the outbreak of the Pfeiffer War in 1870, he moved to his uncle's home in Augsburg, Germany, where he attended a vocational school. In 1875, he studied at the University of Science and Technology in Munich and graduated 5 years later with the first prize and returned to Paris to specialize in refrigeration. At work, he felt the inefficiency of the steam engine, and the idea of designing a new engine was sprouting. He returned to Berlin in 1890 and soon after he built an ammonia-powered engine and studied it, it was unfortunate that the explosion of the engine nearly killed him. After he was discharged from hospital, he continued his work and published in 1893 a famous paper, the theory and design of a reasonable thermal engine to replace existing steam engines and internal combustion engines, in which he proposed the principle of constant-pressure heating cycles (i.e. "diescher" loops) and patented applications.Marine Diesel Engine

             To realize his idea, he found the German Augsburg Machine factory, the predecessor of today's famous man (M. A. N) Company. In 1897, he succeeded in creating a heat engine that worked safely. In Augsburg he personally launched the engine, that moment, the Heat engine field a new technological revolution was born. Although the single cylinder engine has a power of only 14 watts, it is far more efficient than the then steam turbine and the already invented Otto-type internal combustion engine, reaching an unprecedented 26%. Now, the replica of the machine (the original has unfortunately been damaged in World War II) was collected at the German Museum of Technology in Munich, and Dissair is always remembered. The word "Diesel Engine" in English today is named after his surname. However, the diesel engine did not use diesel oil, the use of vegetable oil.Marine Diesel Engine

             Diescher diesel engine is a single cylinder four-stroke diesel engine, although the diesel engine after more than 100 years of development, but its basic principle is based on the principle of pressure expansion diescher proposed. Diesel engine mainly consists of cylinder, piston, connecting rod, crankshaft, intake door, exhaust valve, injector nozzle and other components. The working cycle of 4-stroke diesel engine undergoes four strokes, such as inlet, compression, work and exhaust. The diesel engine in the intake stroke suction is pure air, at the end of the compression stroke, from the fuel injection pump to the high-pressure diesel oil through the injector to spray the human cylinder, in a short time with the compression of high temperature, high-pressure air mixture, to form a combustible mixture gas. The mixing temperature is much more than the ignition point of diesel fuel, the diesel injection cylinder, in a very short period of time, that is, self ignition combustion, gas pressure rises sharply, the temperature rises sharply, under the pressure of high-pressure gas, piston downward movement and drive crankshaft rotation work. Exhaust gas is discharged through the exhaust door, exhaust pipe and other places in the NPC gas.Marine Diesel Engine
