  1. 1. Misfire Detection in Heavy Duty Diesel Engines Using Knock Sensors

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Carl Sjöstedt; [2023]
    Nyckelord :ICE; combustion engine; combustion engines; Scania; diesel; knock; knock sensor; knock sensors; misfire; misfire detection;

    Sammanfattning : In this thesis the possibility of using knock sensors for misfire detection in heavy duty diesel engines is investigated. This is of great interest due to many emission legislations getting stricter, especially in the US where robust misfire detection is mandatory for these types of engines. LÄS MER

  3. 2. Optimal Knock Sensor Spatial Locations of In-line Combustion Engines : A Case Study of Scania Engines

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hassan Hussein; [2023]
    Nyckelord :;

    Sammanfattning : In recent years, there has been a growing interest in utilizing knock sensors as a diagnostic tool for providing valuable insights into the combustion process. These sensors have demonstrated their potential to offer information regarding crucial parameters such as the start of combustion, heat release rate, misfire events, and valve events. LÄS MER

  4. 3. Concept investigation for misfire detection in spark-ignited gas engines

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Stefan Hamberg; [2019]
    Nyckelord :;

    Sammanfattning : As a supplier of sustainable transport solutions, Scania manufactures gas engines. Fueled with biogas, they offer a significant decrease in carbon dioxide emissions compared to standard diesel. LÄS MER

  7. 5. Improving Misfire Detection Using Gaussian Processes and Flywheel Error Compensation

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Gustav Romeling; [2016]
    Nyckelord :Misfire detection; Gaussian processes; Multiple misfires; Flywheel tooth angle errors; EKF; SVM;

    Sammanfattning : The area of misfire detection is important because of the effects of misfires on both the environment and the exhaust system. Increasing requirements on the detection performance means that improvements are always of interest. In this thesis, potential improvements to an existing misfire detection algorithm are evaluated.
