FIELD: motors and pumps. ^ SUBSTANCE: invention relates to engine engineering and, particularly to fuel supply system of diesel engine. According to the invention the fuel supply system in diesel engines contains high-pressure fuel pump, pressure valve, makeup main line, additional channel and non-return valve. The pump is linked with makeup main line and coupled with injector through the pressure valve and high-pressure pipeline. The non-return valve is located in additional channel, which is connected with high-pressure pipeline by one of its ends and with makeup main line by the another end. In addition auxiliary high-pressure fuel pump with pressure valve and high-pressure battery are available in the system. They are coupled with non-return valve by means of makeup main line. The relief valve linked with low-pressure pipeline is mounted on high-pressure battery. ^ EFFECT: improvement of power and economic characteristics and reduction of exhaust smoke emissions and toxicity. ^ 1 dwg |
