Comparative analysis of the operation of a CRDI motor injector under different geographic heights
Main Article Content
Abstract
The present investigation begins by indicating the systems of conventional diesel injection and common rail diesel injection systems, highlighting the advantages of reducing fuel consumption, noise and the reduction of polluting gases to the environment. The theoretical part describes the composition of the common rail fuel systems, the different components, the actuators that were analyzed during the tests both at sea level and at sea level. Subsequently, the experimentation cycle adjusted to the research carried out was determined, the test protocol was established, the driving cycle and places to perform the tests. The test vehicle is shown, the measurement equipment that will be used and subsequently the measurements are made with the oscilloscope for the data collection of the different tests carried out both static and dynamic. The analysis of the results of the static tests shows interesting data about the behavior of the vehicle both in the height and at sea level. The detail of the oscillograms allows us to understand clearly the operation of the actuators of the common rail system.
