  1. 21. Development of Push Control Strategy for Diesel-Electric Powertrains

    University essay from Linköpings universitet/Fordonssystem

    Author : Johannes Bodin; [2018]
    Keywords : diesel-electric powertrain; control strategy; push control; genset;

    Abstract : In diesel-electric powertrains, the wheels are mechanically decoupled from the internal combustion engine (ICE). The conventional control approach for such a powertrain is to let the driver control the traction motor while the ICE realizes speed control, causing power to be pulled through the powertrain.

  3. 22. 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.

  4. 23. A commercial vehicle’s electrical startability

    University essay from KTH/Hälsoinformatik och logistik

    Author : Kristinn Arnar Ormsson; Henrik Persson; [2018]
    Keywords : Startability; commercial vehicle; cranking system; lead-acid battery; state of charge; starter motor; internal combustion engine.; Startbarhet; tunga fordon; startsystem; blysyrabatteri; batteriladdningsgrad; startmotor; förbränningsmotor.;

    Abstract : In commercial vehicles, where the driver overnights with the engine turned off whilestill consuming electricity, it is important to know how much the battery can bedischarged before reliable engine starting is at risk. The vehicle’s ability to crank theengine, i.e. READ MORE

  5. 24. Minimising Fuel Consumption of a Series Hybrid Electric Railway Vehicle Using Model Predictive Control

    University essay from Linköpings universitet/Reglerteknik

    Author : Niklas Sundholm; [2017]
    Keywords : Railway; Vehicle; Model; Predictive; Control;

    Abstract : With the increasing demands on making railway systems more environmentally friendly, diesel railcars have been replaced by hybrid electric railway vehicles. A hybrid system holds a number of advantages as it has the possibility of recuperating energy and allows the internal combustion engine (ICE) to be run at optimal efficiency. READ MORE

  6. 25. Tribological performance of different crankshaft bearings in conjunction with textured shaft surfaces

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Lakshminarayana Reddy Tamatam; [2017]
    Keywords : Tribology; journal bearings; engine main bearings; automotive; friction; wear;

    Abstract : Improving vehicle efficiency and complying to stricter exhaust emission legislations are some of the driving factors to advancement in technology of engine components. The main bearings in an internal combustion engine contribute significant amount of friction. These bearings support engine loads and allow free rotation of the crankshaft. READ MORE
