  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
