RESEARCHING THE TURBO-CHARGER WITH THE
OF COMPUTER AIDED TESTING IN ORDER
TO OUTLINE ITS PERFORMANCES
The present paper shows in specific technical concepts and methods from engineering perspective the problematic aspects concerning the turbocharger construction, problems and operation. After presenting the schematic construction and operation a testing sequence it’s considered. Analyzing the boost-pressure in relation with driving speed, engine temperature, engine speed and other parameters it allows the observer to gain the mathematical correlation between different working conditions. The development of present study aims to the stage of understanding and proper interpretation of the symptoms and problematic aspects related to the turbocharger and gas dynamics on Dacia Logan k9k792 Diesel engine.

STUDY OF IMPLEMENTING POSSIBILITY FOR THE COMPUTER AIDED EVALUATION IN ANALYZING COMMON-RAIL DELPHI INJECTORS
The present applied research shows in usual technical terms and engineering methods from experimental computer aided evaluation some tips and results in injector analyze and testing. After designing a new method for computer aided evaluation of the Delphi injectors some results were acquired. Analyzing the injection system and fuel amount in exploitation conditions allows the researcher to gain some important insight in the defining the problems with operating state of each component. The research development aims toward the problem of easy and rapid evaluation of the injector’s symptoms and operational aspects related to the regime and Delphi management systems on vehicles.
