31-70 CONTRIBUȚII LA CERCETAREA EXPERIMENTALĂ A PARAMETRILOR SISTEMULUI DE ALIMENTARE PRIN INJECȚIE DE LA MOTORUL 3.0i AL AUTOMOBILULUI BMW X5
contributions to the EXPERIMENTAL RESEARCH OF INJECTION FUEL SUPPLY SYSTEM FROM 3.0i ENGINE OF BMW X 5 ROAD VEHICLES
This scientific article shows the results of multiple experimental tests and researches made on the basis of fuel injection process during different operating regimes. Measured parameters are in this case engine speed, fuel consumption, injection timing and engine temperature.
The main objective of these tests is to determine how fuel consumption is influenced by engine speed and engine coolant temperature if the vehicle is operating in neutral gear that means the engine has no load on the crankshaft. In this case the engine speed will be correlated with the accelerating pedal position. The road vehicle on which the tests will be conducted is BMW X5 3.0i model years 2002. There aren’t any detailed studies made on this model. It is a well-known that a considerable number of such vehicles are registered in our country. Besides this body type, BMW Factory equipped other vehicles with this engine.
The experimental tests offer engineers a better understanding of injection process and fuel economy in the case of conventional fuel supply systems. The experimental data are summarized and accurately analyzed and represented.
