METHOD OF CHECKING CONDITION OF VEHICLE POWER PLANT Russian patent published in 2005 - IPC

FIELD: transport engineering; diesel locomotives.

SUBSTANCE: proposed plant includes internal engine, main generator, auxiliary sets and fuel system with fuel tank. For checking condition of power plant according to proposed method, fuel consumption at operation of power plant under load, energy generated by main generator to provided traction and to drive auxiliary sets, fuel consumption per time unit under no-load and time of operation under no-load are measured. Using measured values, fuel consumption during operation of power plant under load is found form equation . Then mean value of specific fuel consumption is found from equation and, basing on results of comparing value with standard value condition of power plant is determined. Leakage of fuel or its draining from fuel system is determined by ratio where is fuel consumption from fuel tank during period . Values of measured magnitudes are recorded in real scale on carrier protected from unauthorized use from which they can be read by machine or transmitted by radio to stationary data processing system.

EFFECT: provision of estimation of condition of power plant in operation and revealing unauthorized use of fuel.
