  1. 1. Impact of Pressure Pulsations on Diesel Air Path Control and Compensation Measures

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : NISHANT DHANORE; [2019]
    Keywords : ;

    Abstract : Stricter pollution norms have led to increased efforts to achieve lower emissions. Exhaust Gas Re-circulation (EGR) is a well known measure to reduce NOx internally in the engine. In order to achieve better performance of an engine in terms of emissions it is very essential to control the flow of exhaust gases through EGR valve. READ MORE

  3. 2. Estimation of Air Mass Flow in Engines with Variable Valve Timing

    University essay from Linköpings universitet/Reglerteknik

    Author : Elina Fantenberg; [2018]
    Keywords : Diesel Engine; Variable Valve Timing; Air Mass Flow;

    Abstract : To control the combustion in an engine, an accurate estimation of the air mass flow is required. Due to strict emission legislation and high demands on fuel consumption from customers, a technology called variable valve timing is investigated. READ MORE

  4. 3. Compressible Flow Modeling with Combustion Engine Applications

    University essay from Linköpings universitet/Fordonssystem

    Author : Carl Vilhelmsson; [2017]
    Keywords : Compressible; Flow; Modeling; Combustion; Engine; Throttle; EGR; Wastegate; Valves; Gas;

    Abstract : The high demands on low fuel consumption and low emissions on the combustion engines of both today, and the future, is highly dependent on advanced control systems in order to fulfill these demands. The control systems and strategies are based on models which describe the physical system. READ MORE

  5. 4. 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.

  6. 5. Comparison of Analysis and Measurement Results for a ST1530 Loader Regarding Dynamic Behavior of Engine Cradle

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Christoper Gustafsson; Mohamed Hemdan; [2015]
    Keywords : Ansys; FEM; Response analyse;

    Abstract : This thesis is a measurement evaluation type of project in which to perform a harmonic response analysis were the results will be compared to measurement data to verify if the ANSYS model is realistic in terms of dynamics. This includes proposing the different parameters that will affect the results of the comparison as well as how to improve further models. READ MORE
