  1. 1. Internal combustion engine durability monitor : Identifying and analysing engine parameters affecting knock and lambda

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Pontus Jääskö; Petter Morén; [2021]
    Keywords : Internal combustion engine; durability testing; data analysis; Otto engine; ignition; ignition timing; fuel injection; Air fuel ratio; partial least squares regression PLSR ; lambda; engine knock;

    Abstract : This study has been performed at Powertrain Engineering Sweden AB (PES), a fully owned subsidiary of Volvo Cars Group, which is constantly working to develop and improve internal combustion engines. As part of this work, durability tests are performed to analyse the impact of wear on the engines. READ MORE

  3. 2. Implementation of a Model Predictive Controller in a Spark-Ignition Engine

    University essay from Linköpings universitet/Fordonssystem

    Author : Gustav Mann; Jakob Luedtke; [2021]
    Keywords : Model Predictive Control; SI engine; Variable Valve Timing; Throttle;

    Abstract : The propulsion of the spark-ignition engine has been investigated and developed during the past century to improve driveability, minimize fuel consumption and emissions, resulting in highly engineered and computerized powertrains. Well balanced engine maps containing coordinated set-points and model-based information sharing have solved the cross-coupling between different control loops. READ MORE

  4. 3. An ICE concept optimized for Series Hybrid Application : A dive into how an ICE pairs with a Series hybrid drivetrain

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Axel Wallenberg; Alexander Frosteman; [2019]
    Keywords : Series hybrid; automobile; internal combustion engine;

    Abstract : This report is a theoretical study of the potential an ICE (internal combustion engine) has when combined with the load case of a high-performance series hybrid drivetrain. It breaks down the different theoretical variables that affect engine efficiency and possible limitations that arise. READ MORE

  5. 4. Stochastic Knock Control for Improved Efficiency

    University essay from Linköpings universitet/Fordonssystem

    Author : Jonas Vedin; Robert Widén; [2019]
    Keywords : Knock control; Stochastic knock control; Knock simulation;

    Abstract : Increasing the efficiency and performance of internal combustion engines is always of interest in the automotive industry. One limiting factor to achieve this in gasoline combustion engines is the ignition timing which can not always be set where optimal ignition efficiency and performance is obtained. READ MORE

  6. 5. Simulation and validation of in-cylinder combustion for a heavy-duty Otto gas engine using 3D-CFD technique

    University essay from KTH/Förbränningsmotorteknik

    Author : Jacob Arimboor Chinnan; [2018]
    Keywords : CFD; AVL FIRE; Otto Gas Engine; Combustion Modelling; ECFM Model; Flame Tracking Particle Model; Flame Tracking Model; G-Equation Model; Ignition Models.; CFD; AVL FIRE; Otto Gasmotor; Förbränningsmodellering; ECFM-modell; Flamspårningspartikelmodell; Flamspårningsmodell; G-ekvationsmodell; Tändningsmodeller;

    Abstract : Utsläpp från bilar har spelat stor roll de senaste decennierna. Detta har lett till ökad användning av Otto gasmotorer som använder naturgas som bränsle. Nya motordesigner behöver optimeras för att förbättra motorens effektivitet. READ MORE
