FIELD: engines and pumps. ^ SUBSTANCE: proposed system comprises fuel tank 2, low-pressure fuel system including fuel heater 8, fuel strainer 9, fuel feed pump 10, fuel fine filter 11 and high-pressure fuel system including high-pressure fuel pump 5, injector 7 and fuel lines 6. System comprises also fuel type change system including control module 17, fuel temperature and pressure pickups 18 and 19, coolant temperature pickup 20, pickup to determine position of rack 21 of pump 5, mode selection keys 22 and fuel type change keys 23, signal lights 24, 25 and 26, solenoid valves to feed and discharge fuel 3 and 4, respectively, additional tank 1 and additional low-pressure fuel system line with electrically driven fuel feed pump 14 and pressure control valve 16. Low-pressure duel system is provided with safety valve 12 arranged downstream of pump 10. Heater 8 is arranged between tank 2 and filter 9, while low-pressure fuel systems are communicated via valves 3 and 4 with pump 5. ^ EFFECT: possibility to run on biodiesel fuel. ^ 1 dwg |
