Análisis comparativo de torque y potencia con la variación de combustibles mediante el uso de una válvula ecológica Marcláis, en distintos vehículos de inyección electrónica utilizando un dinamómetro de rodillo

Abstract

This study aimed to understand the operation of the Marclais ecological valve to reduce the harmful effects of height above sea level on the performance generated by an internal combustion engine. The characteristic torque and power curves were compared in three electronic injection vehicles, varying commercial fuels and using the Marclais ecological valve. The torque and power tests were carried out on a roller dynamometric test bank applying the SAE J 1349 Standard at an altitude of 2800 meters above sea level. The data was obtained in a range of revolutions per minute that starts from 2600 rpm to 5600 rpm and with the variation of the most commercial fuels in the central zone of the country, being the extra and super fuel. When analyzing the obtained data in power, there was an increase from 4% to 7% when changing from extra to super fuel. In torque, there was an increase from 5% to 6% changing from extra to super fuel. When implementing the Marclais ecological valve, it did not present notable variations. A comparative analysis was established to validate the obtained data using the Anova method for a single factor. Concluding that the Super fuel presents a better behavior in both power and torque, and the implementation of the Marclais ecological valve does not contribute to better torque and horsepower performance. It is recommended that the test vehicles should be in good condition for the effect of the Marclais ecological valve can be concluded.
