Identificación del modo de trabajo de un motor GDI al variar la altura mediante una prueba estática a ralentí y 2500 RPM

In this study, it is analyzed experimentally how to identify the working mode that occurs in an ignition engine caused by direct fuel injection and determine if the variation of the height with respect to sea level influences the selection of the mode of operation. work that can vary between homogenous, homogeneous, poor and stratified. Through a static test developed based on the test protocols established in the Ecuadorian Technical Standard "NTN INEN 2213" called TIS (Two Iddle Speed) every 500 meters from a height of 0 meters to 4500 meters. The tests are carried out on a Mazda CX-5 1998 cm3 vehicle with a GDI system with multimode operation of three types of mix, plus a Maxidas automotive scanner and a Garmin GPs. The results obtained reveal how the work mode in a direct fuel injection system variesand it was determined that the working mode does not vary when increasing the height with respect to sea level, but it varies within the operating ranges of each mode, in addition, it was established that in this test only the stratified and homogeneous poor mode is executed
