  1. 6. Modeling and Estimation of Long Route EGR Mass Flow in a Turbocharged Gasoline Engine

    University essay from Linköpings universitet/Fordonssystem

    Author : Erik Klasén; [2016]
    Keywords : Long Route Low Pressure LR LP EGR SI Gasoline Spark Ignited Engines Modeling Modelling Mass Flow Estimation;

    Abstract : Due to the continuous work in the automobile industry to reduce the environmental impact, reduce fuel consumption and increase efficiency, new technologies need to be developed and implemented in vehicles. For spark ignited engines, one technology that has received more attention in recent years is long route Exhaust Gas Recirculation (EGR), which means that exhaust gases after the turbine are transported back to the volume before the compressor in the air intake system of the engine.

  3. 7. Slow-response generator

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Adam Davidsson; Fredrik Lindbom; [2015]
    Keywords : Slow-response; EGR;

    Abstract : Because of environmental pollution, forces the automotive industry constantly reduced emissions requirements legislated by the authorities. Improved techniques for engine control are a must for bringing down emissions. The use of an Exhaust Gas Recirculation (EGR) reduces NOx emissions significantly. READ MORE

  4. 8. Exhaust gas recirculation on twin shaft gas turbines - A study to improve part load performance

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Benjamin Mattsson; [2015]
    Keywords : Exhaust gas recirculation; EGR; FGR; Twin shaft gas turbine; Part load; Emissions; SGT-750; IPSEpro; SimTech; Technology and Engineering;

    Abstract : By recirculating exhaust gases to the gas turbine inlet a temperature rise and hence, a density reduction, is achieved at the compressor inlet. For a constant volume flow this results in a reduced mass flow, ultimately affecting the temperature of the flame, and the emissions, at part load. READ MORE

  5. 9. Modeling, Simulation and Control of Long and Short Route EGR in SI Engines

    University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Author : Junting Qiu; [2015]
    Keywords : Mean value engine modeling; EGR; long route; short route; residual gas fraction; PID;

    Abstract : Modern engines are faced with increasingly stringent requirements for reduced fuel consumptionand lower emissions. A technique which can partly be used to reduce emissionsof nitrogen oxides is recirculation of combusted gases (Exhaust Gas Recirculation, EGR). READ MORE

  6. 10. Modeling and Simulation of Urea Dosing System

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Zaki Ahmed; [2013]
    Keywords : Modeling; Simulation; Urea; Dosing;

    Abstract : To protect our health and environment from pollution, among others regulatory agencies in the European Union (EU) and legislation from the U.S. Environmental Protection Agency (EPA) has required that pollutants produced by diesel engines - such as nitrogen oxides (NOx), hydrocarbons (HC) and particulate matter (PM) - be reduced.
