Bestämning av motoremissioner från arbetsmaskiner inom jord- och skogsbruk

摘要: Modern agriculture and forestry are based on the use of large diesel-fuelled vehicles. The emissions from these vehicles cause substantial damage to production area surrounding environment. A useful method for analysis environmental load a chain or process is LCA. results LCA analyses performed food show that an important part caused by internal combustion engines. Very few data available discharge agricultural tractors. Therefore, used in most studies measurements trucks wheel loaders. There many reasons believe figures not representative tractors performing typical work operations. shortage contributes possibility describing loads modern may have very high error levels uncertainties. report describes study order quantify engine medium size (70 kW) tractor when To obtain emission values specific different driving operations, time series at recorded These then combined with test bench data, calculate each operations studied were ploughing, harrowing, stubble cultivation, sowing, loading transporting. Emissions calculated two diesel fuels RME. general a) one single factor all types result levels, b) factors normally can be Important areas further research described discussed last report.
