INVESTIGATION OF OPERATIONAL RELIABILITY OF DIESEL ENGINE FUEL SUPPLY SYSTEMS

The results of the investigation of operational reliability of the fuel supply system of diesel engines F1A FIAT DUCATO cars, the main reasons for the system's loss of operability, the numeri-cal characteristics of its failure-free performance are given. On the basis of processing the array of experimental data on faults and failures in the system, the regularities of change of failure intensi-ty and probabilities of failure-free operation of its main parts depending on vehicle mileage are determined. Methods and algorithm of troubleshooting and timely elimination of damages occur-ring in the fuel supply system are proposed and tested at the FIAT PROFESSIONAL dealership in Vladimir. The introduction of the results of the performed investigations into the production pro-cesses of car service enterprises allows to significantly reduce the costs of maintaining the opera-ble state of the diesel engine fuel supply system in operation.
