  1. 1. Evaluation of model-based fault diagnosis combining physical insights and neural networks applied to an exhaust gas treatment system case study

    University essay from Linköpings universitet/Fordonssystem

    Author : Björn Kleman; Henrik Lindgren; [2021]
    Keywords : model-based; fault diagnosis; neural networks; data-driven; Hybrid; SCR; exhaust gas treatment system; recurrent neural networks; grey-box; heavy duty truck; fault isolation; fault detection; diagnosis; urea; machine learning; Scania; structural model; MSO; residual; Fault Diagnosis Toolbox;

    Abstract : Fault diagnosis can be used to early detect faults in a technical system, which means that workshop service can be planned before a component is fully degraded. Fault diagnosis helps with avoiding downtime, accidents and can be used to reduce emissions for certain applications. READ MORE

  3. 2. Internal Combustion Engine Calibration considering the Embedded Systems Sensor Accuracy

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Daniel Rodríguez Pascual; [2021]
    Keywords : ;

    Abstract : In recent years, the increasing economic, environmental and legal demands on internal combustion engines to reduce emissions and fuel consumption are a major challenge. A lot of effort has been put into achieve reliable methods of diagnosis, fault detection and monitoring to increase safety and efficiency in vehicles. READ MORE

  4. 3. Information Fusion of Data-Driven Engine Fault Classification from Multiple Algorithms

    University essay from Linköpings universitet/Fordonssystem

    Author : Ninos Baravdish; [2021]
    Keywords : Engine fault diagnosis; Fault classification; Information fusion; Decouple fault;

    Abstract : As the automotive industry constantly makes technological progress, higher demands are placed on safety, environmentally friendly and durability. Modern vehicles are headed towards increasingly complex system, in terms of both hardware and software making it important to detect faults in any of the components. READ MORE

  5. 4. Fault Clustering With Unsupervised Learning Using a Modified Gaussian Mixture Model and Expectation Maximization

    University essay from Linköpings universitet/Fordonssystem

    Author : Kevin Lindström; [2021]
    Keywords : ;

    Abstract : When a fault is detected in the engine, the check engine light will come on. After that, it is often up to the mechanic to diagnose the engine fault. Manual fault classification by a mechanic can be time-consuming and expensive. READ MORE

  6. 5. Injector diagnosis based on engine angular velocity pulse pattern recognition

    University essay from Uppsala universitet/Signaler och system

    Author : David Nyman; [2020]
    Keywords : machine learning; supervised machine learning; neural network; internal combustion engine; fault diagnosis;

    Abstract : In a modern diesel engine, a fuel injector is a vital component. The injectors control the fuel dosing into the combustion chambers. The accuracy in the fuel dosing is very important as inaccuracies have negative effects on engine out emissions and the controllability. READ MORE
