33-36 CONTRIBUȚII LA CERCETAREA PROCEDURII DE VERIFICARE A INJECTOARELOR COMMON-RAIL ÎN CAZUL MOTORULUI 1.8 TDCI DE LA FORD FOCUS


CONTRIBUTIONS TO THE RESEARCH OF INSPECTION PROCEDURE FOR THE COMMON-RAIL INJECTORS IN THE CASE OF 1.8 TDCI ENGINE FROM FORD FOCUS
The present research work develops a practical procedure of inspection sequence for the case of injectors and injection system as a whole to sketch the important steps required. Construction and operational analyze is also important as well as engine control parameters, main injection, temperature and symptomatic behavior, in specific conditions, but here it’s most highlighted the inspection procedure. By using injector monitoring equipment connected to the electronic control unit of the engine via digital interface. Thus are pointed out the fuel amount, fuel pressure and the injector behavior from the Ford Focus engine (1.8 TDCi Turnier/DNW/85.0 kW) with common-rail injection system. Significance and opportunity for inspecting the injectors from Ford Focus 1.8 TDCI is based on recurrence of the symptoms regarding power loss and engine problems in operation. Realizing the present paper leads to a goal of highlighting a problem related to the fuel system components as injectors from the common-rail compression ignited engine in particular working conditions.
