  1. 1. Knock model evaluation - Gas engine

    University essay from KTH/Förbränningsmotorteknik

    Author : Nishchay Sharma; [2018]
    Keywords : Knocking; Spark-Ignited; Internal Combustion Engine; Spark-Knock; Empirical Correlation Models; BOOST; Combustion Phasing; Spark-advance; Combustion Duration; Knock Prediction Parameter.; Knack; Otto-förbränning; Förbränningsmotor; Empiriska korrelationsmodeller; BOOST; Förbränningsfasning; Tändvinkel; Förbränningsduration; Knackprediktering;

    Abstract : Knack i en förbränningsmotor är en typ av onormal förbränning. Det är ett komplicerat fenomen som beror på flera fysiska faktorer och resulterar i högfrekventa tryckoscillationer inuti förbränningskammaren. Dessa oscillationer kan skada motorn och fenomenet hämmar motorns effektivitet. READ MORE

  3. 2. Development of a model for spark plug wear detection in gas engines

    University essay from KTH/Energiteknik

    Author : Leonard Sang Tuei; [2018]
    Keywords : ;

    Abstract : Spark plugs in Otto engines are usually subjected to service intervals in terms of mileage as a preventive maintenance strategy. The service interval is aimed to cover and safeguard the worst case scenario of spark plug wear during operation. READ MORE

  4. 3. Knock Model Evaluation – Gas Engine

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Nishchay Sharma; [2018]
    Keywords : Knocking; Spark-Ignited; Internal Combustion Engine; Spark-Knock; Empirical Correlation Models; BOOST; Combustion Phasing; Spark-advance; Combustion Duration; Knock Prediction Parameter.; Knack; Otto-förbränning; Förbränningsmotor; Empiriska korrelationsmodeller; BOOST; Förbränningsfasning; Tändvinkel; Förbränningsduration; Knackprediktering.;

    Abstract : Knocking is a type of abnormal combustion which depends on several physical factors and results in high frequency pressure oscillations inside the combustion chamber of a spark-ignited internal combustion engine (ICE). These oscillations can damage the engine and hamper its efficiency, which is why it is important for automakers to understand the knocking behavior so that it can be avoided during engine operation.

  5. 4. 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

  6. 5. Concept study - lower exhaust gas temperature in Scania buses

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Birk Jansson; Mikael Jarsäter; [2013]
    Keywords : Exhaust gas temperature reduction; diffuser; bus; EuroVI; venturi; CFD; Avgastemperaturssänkning; buss; diffusor; EuroVI; CFD;

    Abstract : The thesis aims to lower the exhaust gas temperature on the coming EU6 Scania buses D7 and Otto gas and is carried out as a final part of the studies in the mechanical engineering program, KTH Stockholm. Euro 6, a new emission standard requirements for heavy duty trucks and buses, puts new demands on the amount of particulate matter and nitrogen oxides that can be emitted. READ MORE
