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

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Sammanfattning : 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. LÄS MER

  5. 4. Stochastic Knock Control for Improved Efficiency

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Jonas Vedin; Robert Widén; [2019]
    Nyckelord :Knock control; Stochastic knock control; Knock simulation;

    Sammanfattning : 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. LÄS MER

  7. 5. 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
