INTEGRATED FUEL SUPPLY SYSTEM FOR ELECTRIC DIESEL LOCOMOTIVE LDE 2100 HP USING PURE BIODIESEL FUEL B100

摘要

The invention relates to an integrated fuel supply system for an electric locomotive of 2100 HP which uses pure biodiesel fuel B100, in ambient negative temperature conditions. According to the invention, the system comprises a main fuel tank (1) heated with a heating coil (2) and monitored by a temperature sensor (3) wherefrom a main fuel pump (5), using a retaining valve (4), transfers the biodiesel fuel, through some heated supply pipes (6) to a coarse fuel filter (7), to some fine fuel filters (8) and, then, to some injection pumps (9) of a Diesel engine (10), while the excess gas-oil is transferred through a pressure valve (11) to an auxiliary tank (12) and, further on, through some over-flow and return pipes (13 and 14), back to the main tank (1), an equipment (15) for heating and maintaining the Diesel engine (10) supplied in the first place with biodiesel fuel from an auxiliary tank (16) which is electrically heated by an electrical resistor (17) and monitored by a temperature sensor (16), its operation being ensured by a computerized system (34) which monitors the temperature of cooling fluid, lubricating oil and biodiesel fuel in various points of the fuel supply circuit, as well as a series of digital signals (36) from various switching equipments of the locomotive.
