Análisis de la presión interna del cilindro de un M.C.I utilizado en un vehículo híbrido, mediante un transductor de presión y un osciloscopio automotriz

Abstract

The objective of this project was to adapt a system of programmable electronic injection to an internal combustion motor with a carburetor. And realize a comparative analysis of gas emissions concerning an ideal stoichiometric. For which emission tests were done at idle at half load and full load. Diverse tests of carbon monoxide were done, carbon dioxide, hydrocarbon, and lambda factor, which allow learning the level of contamination in which the internal combustion motor it is found. Through the experimental method, a dispersion comparative graph was done for the visual analysis of the emissions. Also for the statistical analysis, a type T-test was done for means of two paired samples with a 90 % reliability of a significant level of 0.05 giving a result that exists a significant difference of the motor of programmable electronic injection with the motor with a carburetor. The motor with electronic injection stands out due to working with an ideal stoichiometric in idle, at half load and full load, so that the gases expelled by the motor are less contaminated due to the fuel supply will be programmed to supply de adequate proportions as well as correct at all times of its operation. It is concluded that contaminating gas emissions were lowered notably, obtaining as result a lower level of contamination by the electronic injection motor. It is recommended for future studies to develop a comparative analysis of gas contaminating emissions of the electronic injection motor with super fuel versus the electronic injection motor with ethanol fuel and realize a statistic analysis to observe the behavior of contaminating gases of a motor working with friendly fuel for the environment such as ethanol.
