Estudio del funcionamiento de un motor de inyección directa a gasolina en diferentes alturas con respecto al nivel del mar

Abstract

This study it’s being developed to determined a methodology that will show the influence in the variation of any injection engine comparing high altitude with sea level performance of any injection engine that uses direct gasolina, and executes different tasks, stratified, low homogenous and homogenous. With the use of a scanner and GPS it was posible to conduct a stationary and dynamic test every 500 meters of altitude with a Mazda CX-5 vehicle, applying the specific protocols that are established by the NTN INEN 2213 (Norma Técnica Ecuatoriana) that were conducted on both static(TIS) and dynamic tests. “Analysis and developed of different variables in an electronic injection engine according to the changes of altitude and against sea level performance”. Different results were obtained by developing stratified, low homogenous and homogenous tasks. In both types of testing, the variation of the altitude against sea level performance shows how the pressure of the fuel in the rail is different, the increase in the air, starting time and the performance with the sensors controlling different emissions of any contaminant according to the task mode.
