FIELD: engines and pumps.
SUBSTANCE: in internal combustion engine starting system containing cooling system of internal combustion engine, liquid heater connected to the main line of standard cooling system, heat carrier temperature sensors, standard fuel system of internal combustion engine with standard fuel tank and booster fuel pump, additional oil pump, independent electric power supply, the latter is made in the form of diesel generator unit with charging device of starter accumulator battery of locomotive, internal combustion engine starting system is equipped with additional fuel tank provided with overflow pipeline connected through drain pipeline to standard fuel tank, pipeline with valve and throttle connecting the additional fuel tank to delivery fuel pipeline, standard fuel system, pipeline with valve connecting the additional fuel tank to pipeline of diesel generator unit, pipeline with valve and pipeline connecting the additional fuel tank with liquid heater to standard fuel system parallel to booster fuel pump there installed is additional fuel pump, additional oil pump is connected parallel to standard purge oil pump, heat carrier temperature sensors for control of operation of the system are connected to pipeline with the lowest heat carrier temperature of cooling system of internal combustion engine in operating mode of internal combustion engine starting system; besides, liquid heater connected to additional fuel tank through pipeline with a valve is installed in driver's cabin.
EFFECT: increasing downtime of inoperative engine during cold seasons of the year in constant readiness for startup; thus, operating life of internal combustion engine is maintained and its operating reliability is improved.
