  1. 1. A GENeric Internal Combustion Engine model : LiU-Genie

    University essay from Linköpings universitet/Fordonssystem

    Author : Oskar Lind Jonsson; [2021]
    Keywords : ;

    Abstract : As the demand for control in modern vehicles grows, models are needed to develop a better understanding of processes and engine behavior. The thesis contributes with a generic extended MVEM with SI and CI as well as VVA compatibility and modeling structure using MATLAB/Simulink environment. READ MORE

  3. 2. Virtual Sensor Describing the Intake Manifold Pressure Close to the Cylinder Ports

    University essay from KTH/Förbränningsmotorteknik

    Author : Sotirios Tsironas; [2018]
    Keywords : ;

    Abstract : Ökad efterfrågan på effektivare motorer och strängare lagstiftning rörande avgasutsläpp kräver en noggrannare styrning av motorns driftsparametrar. Denna styrning är mestadels baserad på ett antal fysiska sensorer som spelar en viktig roll vid utsläppsrelaterad feldiagnostik. READ MORE

  5. 4. Coordinated Model Based Thottle and Turbo Control

    University essay from Fordonssystem; Tekniska högskolan

    Author : Petter Carlsson; [2013]
    Keywords : MVEM; Turbocharge; Oscillation; Compensation control;

    Abstract : Downsizing and turbocharging is one way to meet the high demands on fuel consumptionand performance on todays engines. The air-path system in a turbochargedspark ignited engine is a complex system and because the intake manifoldpressure is tightly connected with the engine torque a consistent and robustcontrol is needed.
