In 1892 Rudolf Diesel, a German nation to plan a new type of internalcombustion engine which requires no spark plugs to ignite the fuel, ie dieselcompression ignition engines are also called, which means the process ofcombustion itself, that is because the fuel spray into the air-filled cylindertemperature and high pressure. Fuel is burned with air. Instead of ignitionsystems in Otto engines it is necessary to pump injection (injection pump) andthe nozzle (atomizer devices) to spray fuel. In the fuel system are functioninggovernor to change the amount of fuel, so that rotation (motor shaft) fixed at apredetermined rate. Although the external loads change, the tool set at all times(fast, accurate and automatic), the amount of fuel according to circumstancesoutside the acceptable load.
