Abstract:
This project analyzes current technologies for applications in heavy vehicles, more specifically trucks, explaining in greater detail the technology used at the engine level and in exhaust gas aftertreatment systems. The objective of the project is to study the real road emissions of a series of trucks using different fuels, both conventional (diesel) and alternative (natural gas). Field measurements are carried out thanks to a (portable) equipment for measuring emissions, called PEMS. On the other hand, with the intention of analyzing the total environmental impact of the fuels examined, a comparison is established taking into account both the CO2 emissions from the extraction and distribution of the fuel (Well-to-tank, WtT), and those related to that issued by vehicle (tank-to-Wheels, TtW). This type of analysis (called Well-to-Wheels, WtW) is frequently carried out to determine with certainty what is the true reduction in the carbon footprint of currently available fuels.
