34-70 CONTRIBUȚII LA STUDIUL ECONOMIEI DE COMBUSTIBIL ȘI A AMPRENTEI DE CARBON ÎN CONDIȚII VARIATE DE FUNCȚIONARE PENTRU UN AUTOVEHICUL URBAN COMPACT LA UNIVERSITATEA TEHNICĂ DIN CLUJ-NAPOCA

CONTRIBUTIONS TO FUEL ECONOMY AND CARBON FOOT PRINT STUDY IN VARIOUS OPERATION CONDITIONS FOR A CITY COMPACT SIZE CAR WITH AT TECHNICAL UNIVERSITY FROM CLUJ-NAPOCA
Carbon footprint and automotive pollution are some important concerns in transportation field. Main objective of the present work is to propose, develop and implement the new complex method of computer aided measurement concerning carbon footprint in urban driving condition of a city car with instruments and equipment available at Technical University from Cluj-Napoca. Specific objectives consist in experimental research of fuel consumption and economy, determination of pollutant emissions from the motor vehicle and pointing out the method’s fundamentals at Technical University of Cluj-Napoca. A new method of advanced technological research was developed during this study. The junction of computer aided processing and fuel/chemical efficiency evaluation is pointed out during the paper development. There were also highlighted the economy and carbon footprint trend lines in each particular context.

33-48 CERCETAREA SEMIOTICĂ A TREPIDAȚIILOR/ VIBRAȚIILOR ȘI A MERSULUI RALANTI NEREGULAT LA OPEL ZAFIRA

SEMIOTIC RESEARCH OF VIBRATIONS AND
IRREGULAR IDLE RUNING SYSTEM
FROM OPEL ZAFIRA
The semiotic research paper searches the causal factors, sequences and significant symptoms in diagnosis process of the vibrations and engine irregular idle running in the case of Opel Zafira. The symptoms, after some instalments were made, consisted in irregularly running, low level vibrations and communication errors. The main objective of the present research is to determine the causal factor for all the recorded symptoms during the abnormal operation. The present paper searches to solve or to discover the only problem of the power-train system because the engine runs irregularly abnormal in idle speed and presents some vibrations. The result is related to procedures done at some point in time on the auxiliary systems.
