Fuel Supply system with electronically control of diesel locomotive engine

Meeting the current requirements for fuel economy and exhaust gases toxicity characteristics of locomotive-type diesel engines is possible only when using electronic systems of automatic control of engine parameters. However, said control systems are not yet widely used in locomotive-type diesel engines of domestic production. The paper describes the electronic system of fuel supply automatic control of locomotive-type diesel engine as D50 produced by «Dieselavtomatika» (Saratov city). The main elements of this system are the electronically controlled metering valves placed in the cavities of the plunger pump sections of high pressure fuel pump. Dependencies of the duration of metering valve opening on camshaft frequencies are obtained. The results of computational studies are used to improve and fine-tuning of the developed fuel supply system.
