Evaluation of the consumption and emissions of a vehicle implemented with a MARCLAIS valve at 2754 masl

Abstract

Introduction: according to the literature, the Ecological Valve Marclais is an automotive device used to reduce pollutant emissions and fuel consumption because of height above sea level. Objectives: to corroborate this information, the device was installed in a gasoline-powered electronic injection vehicle and tests of pollutant emissions and fuel consumption were conducted. Methodology: the emissions tests were conducted according to the NTE INE 2 203:2000 standard, at different engine speeds, idle, 2000rpm and 4000rpm, and a KEIN 4-2 gas analyzer. Fuel consumption was conducted through dynamic tests according to SAE J 1321:2012 standard, on a route of 12.3 km at an average speed of 50km/h, with extra fuel in the city of Riobamba at 2750msnm. Results: when analyzing the data obtained from pollutant emissions, a 20% decrease in Carbon Monoxide (CO) and Hydrocarbons (HC) was evidenced by 24%, these two gases being the most polluting and those that are sought to reduce to the maximum, Oxygen (O2 ) and Carbon Dioxide did not present notable variations, likewise, in fuel consumption a significant saving of 23.56% was obtained.  Conclusions: The Marclavalve contributes to reducing emissions and consumption from 1800 meters above sea level.
