Experimental Analysis to Characterizing CO2 Emission of Roller
Abstract:
CO2 emission from construction equipment directly affects the global warming by increasing greenhouse gas. While there are many indirect sources in construction processes that affect the global warming, such as construction materials, CO2 emission is considered as one of controllable and measurable sources of greenhouse gas if construction engineers make a careful plan of equipment schedule according to CO2 emissions and equipment productivity. This paper introduced a CO2 measurement method in a real-time during construction phase and analyzed the relationship among gas velocity, rpm and CO2 emission. While engine rotation and CO2 emission are closed related to each other, their relationship is not perfectly coincident because of the coupling effect between rpm and CO2 emission. In addition, complicated mechanism behind the CO2 emission exists even during the equipment operation because of the various conditions of equipment, rolling resistance, working type, and field environment. The findings from this research will help an environment-friendly planning of activity scheduling by considering CO2 emission together with the equipment productivity.
