Abstract
One of the important environmental parameters in engine emissions and air-to-fuel ratio is the Barometric pressure. In order to determine the full impact of this environmental variable in Tecumseh engines an experiment was conducted. The experiment was conducted along five distinct points of barometric pressure from 1000 m to sea level. In these five environmental conditions CO and CO2 levels were measured. Also, as the most important parameter, and main object of the study, air-to-fuel ratio - λ, was determined. The purpose of this paper is to determine a reference engine running condition to reproduce it in Laboratory, as close as possible, to the real sea level operation. Finally an oxygenated fuel is presented as ally to compensate the lack of oxygen at high altitudes.
