33-38 CONTRIBUȚII LA CERCETAREA EXPERIMENTALĂ A SIMPTOMELOR PROBLEMATICE ALE SISTEMULUI COMMON-RAIL DELPHI DE LA MOTORUL 1.5 DCI K9K792 DE LOGAN DACIA-RENAULT


CONTRIBUTIONS TO EXPERIMENTAL RESEARCH OF PROBLEMATIC SIMPTOMS OF THE COMMONRAIL DELPHI SYSTEM FROM THE 1.5 DCI K9K792 ENGINE OF DACIA-RENAULT LOGAN
The experimental research paper shows the elements and important values in applied study of the injection system testing in the case of 1.5 dCi engine from Dacia Logan. Compression ignited engines are more economically efficient due to their higher compression ratio and injection procedure. They are very attractive due to their fuel efficiency. They are also more expensive than gasoline engines and more pollutant concerning the particles and exhausted smoke. The monitored car had some problems with the injection system (control unit, high pressure pump and injectors). Some components were replaced but ”on-board light” still turns on from time to time indicating errors in injection assembly. The symptoms were grouped and the electrical circuit closely inspected and the faults were repeatedly identified.
