Abstract:Vračanje izpušnih plinov je učinkovita metoda za zmanjšanje emisije dušikovih oksidov (NOx). Dva različna postopka vračanja izpušnih plinov se lahko uporabita za tlačno polnjene dizelske motorje. Pri nizkotlačnem postopku vodimo del izpusnih plinov, ki iztekajo iz turbine, na polnilno stran motorja,kjer se pomešajo s svežim zrakom. Alternativna pot je visokotlačni postopek. Pri tem postopku odvzemamo del izpušnih plinov že pred turbino in jih pri nadtlaku tlačimo v polnilni zbiralnik za kompresorjem. Z enorazsežno metodo smo simulirali tokovne in termodinamične procese v štirivaljnem motorju z vračanjem izpušnih plinov po obeh postopkih. Raziskali smo možnost doseganja želene stopnje vračanja z obema postopkoma in njun vpliv na obratovalne karakteristike motorja in turbokompresorja. Rezultati so prikazani v prispevku.

Title:An analysis of the application of high- and low-pressure exhaust-gas recirculation to a turbocharged diesel engine
Abstract:Exhaust-gas recirculation (EGR) is an effective way of reducing NOx emissions.Two different strategies can be applied when using EGR in a turbocharged diesel engine. The first one is known as low-pressure EGR, where a passage is provided enabling exhaust gasses from below the turbine to pass to the fresh-air side of the engine. Its alternative is high-pressure EGR. In this EGR configuration the exhaust gas is withdrawn from the exhaust manifold above the turbine and fed to the intake manifold below the compressor. The applications of both strategies to a four-cylinder diesel engine were studied by means of a one-dimensional simulation. The possible range of EGR applications for both concepts and their effects on the engine and turbocharger operations were examined and are discussed in this paper.
Keywords:internal combustion engine, exhaust gas recirculation, NOx emissions, measurements, simulations
