【 摘 要 】

Problem statement: Bulldozers consume a large amount of diesel fuel andconsequently produce a significant quantity of CO₂. Environmental and economic cost issuesrelated to fuel consumption and CO₂ emission represent a substantial challenge to the miningindustry. Approach: Impact of engine load conditions on fuel consumption and the subsequent CO₂emission and cost was analyzed for Caterpillar bulldozers. Results were compared with the data onbulldozers' fuel consumption from an operating coal surface mine in the United States. Results: Thereis a strong linear correlation among power, fuel consumption and engine load factor. Reduction in loadfactor by 15% may significantly reduce the fuel consumption and the CO₂emission.Conclusion/Recommendation: Application of appropriate bulldozer's load factor may help mineoperators manage fuel consumption, cost and environmental burden.
