Evaluation of fuel and spark system variables of a gasoline engine due to lack of timely replacement of fuel filter

In this study, the effect of fuel filter lifetime on the temperature of gasoline output from the fuel pump, ignition advance, injector injection pressure and electric current of the fuel pump of a gasoline engine was examined experimentally with the aim of improving the variables of fuel and ignition systems. The results of this study showed that the lowest temperature of gasoline output from the fuel pump and the amount of electric current of the pump using a new filter were 37.5 ˚C and 2.88 A, respectively. The highest temperature of gasoline output from the fuel pump and the amount of electric current of the pump, measured using a filter with a range of 60,000 km, were 40.5 ˚C and 4.12 A, respectively. The highest injection pressure of the injectors and the lowest amount of ignition advance at 1000 rpm engine speed and using the new filter were 3.5 bars and 7 degrees, respectively. The lowest injection pressure of the injectors and the highest amount of ignition advance at 5000 rpm engine speed by using a 50,000 km filter lifetime were reported as 2.5 bars and 37 degrees, respectively. It is lucid that filters with a lifespan of more than 15,000 km reduce the combustion quality and efficiency of the engine.
