33-39 CONTRIBUȚII EXPERIMENTALE LA DIAGNOSTICAREA MOTORULUI 1,9 TDI DE LA VW VENTO


EXPERIMENTAL CONTRIBUTIONS TO DIAGNOSIS
OF 1.9 TDI ENGINE FROM VW VENTO
The present paper offers an experimental contribution to the research of methods and strategies concerning the fuel consumption and injected quantity in the case of 1.9 TDI engine from VW Vento. It is an opportunity to study and document some aspects regarding the fuel quantity injected and how it may be optimized in experimental conditions in order to reach lower specific consumption, improved engine energy efficiency and even lower pollution. In the present paper is shown that the small intervention on the fuel injection pump may offer a significant change in spray quantity and further more influencing the overall consumption and efficiency. Finally the engine was optimized and the fuel injected quantity correlated with the operating regime in order to improve operational efficiency.
