This study describes the development of a mock model of exhaust pipe emissions from the Urban Public Transport System (UPTS). The aim is to use this tool to calculate and monitor emissions produced by the UPTS vehicles ...

Ethanol is a renewable fuel and it is considered an alternative to gasoline in Otto-cycle engines. The present study evaluated the behavior of exhaustion gas carbon monoxide (CO) and total hydrocarbons (THC) according to ...

Study of consumption rate and gaseous pollutant emission from engine tests simulating real work conditions, using spark point manually controlled and exhaust gas recirculation (EGR) in diverse proportion levels. The objective ...

This paper describes the use of blends of diesel/biodiesel to obtain new microemulsion systems and their application as fuels for diesel engines. The blends were prepared using 5 vol.% (B5) and 20 vol.% (B20) biodiesel ...

Simple, inexpensive and accurate methods for assessing the spatial distribution of traffic emissions are badly needed for the environmental management in South American cities. In this study, various spatial disaggregation ...
