INDEPENDENT INSTALLATION TO KEEP WARM AND ECONOMIC OPERATION OF THE LOCOMOTIVE DIESEL ENGINE

摘要

The invention relates to auxiliary means for start of internal-combustion engines. Installation comprise a coolant circuit of the traction diesel engine (1) which can be common with the cooling circuit of the auxiliary diesel engine (MDA) (9), the group of radiators (2) electric or thermal heater (4) which provides coolant heating, a temperature sensor (5), adapters block (14), the PLC (programmable logic controller) for control and monitoring of the operation, (15), the block of electric execution devices (16), the recording and display block (12), and the communication system to a central dispatcher (13). A temperature sensor controls the starting-off of the independent power source, when the locomotive is long stationary or in the shed. An auxiliary diesel-generator synchronous three- phase group (9 and 10) which supplies electric or thermal heater (4), the auxiliary pump (3), a voltage adapter (7) which ensures the supply of other electrical circuits of the locomotive (6) and the charging of accumulator battery (11), and a voltage adapter (8) which ensures the supply of the auxiliary pump when the diesel engine (1) is stopped. Technical effect of the invention is the optimization of keeping warm the traction diesel engine, extending the concept of „keeping warm" to the accumulator battery and the driving cab.
