Rudolf Dissel, a German inventor, invented the first diesel engine. Diesel began to study power machines at 1885. He used the high temperature of compressed air to directly ignite the fuel in the cylinder, and obtained the patent of this machine in 1892. In the same year, he made the first testing machine, namely the original diesel engine.

At that time, the ignition internal combustion engine invented by nikolaus otto was mature, but the fuel of Otto's engine was gas, which was not convenient to store and carry, and its efficiency was also affected. At the end of 19, petroleum products were extremely scarce in Europe, so Diesel decided to use vegetable oil to solve the fuel problem of the machine (he experimented with peanut oil).

1892, diesel finally developed a practical diesel-powered compression ignition engine. This kind of engine has great torque and low fuel consumption, and can use inferior fuel, showing brilliant development prospects. Dissel immediately plunged into the commercial adventure of diesel engine production.

Unfortunately, as an excellent engineer, Dissel lacks business sense. He is in financial trouble. 19 13 diesel is on the verge of bankruptcy. However, the diesel engine invented by diesel engine has been more and more widely developed in automobile, ship and the whole industrial field.
