Analysis of Gases of the Engine of a Vehicle through Static and Dynamic Tests

Abstract:

The objective of this article was to analyze the ignition engine emissions caused by international protocols for the evaluation of the variability between static and dynamic tests. The respective laboratory tests were performed at an altitude of 2810 m above sea level in the city of Quito-Ecuador. The vehicle experienced was a Nissan Sentra 1.6 L., subjected to tests static (idle; 2500 rpm), and dynamic (ASM 50/15, ASM 25/25, IM 240). It is concluded that the injection system of the vehicle works incorrectly in the static test, because the lambda factor fluctuates between 1.18 and 1.79 which affects the normal operation of the engine due to impoverishment of the mixture; while in the dynamic test system the lambda factor 1 condition is approached ideally for the formation of the stoichiometric mixture. The estimation of the emission factors was: CO of 0.58 g/km, HC of 0.01006 g/km and NOx in 0.09 g/km.
