  1. 1. An Investigation of Maximum Brake Torque Timing based on Ionization Current Feedback

    University essay from Institutionen för systemteknik

    Author : Janek Magnusson; [2007]
    Keywords : MBT timing; maximum brake torque; spark advance; PPP; tändningstidpunkt; maximalt arbete; MBT; jonström; jonströmsåterkoppling; PPP;

    Abstract : For every operating condition of an internal combustion engine there exists an optimal spark timing, called maximum brake torque (MBT), which maximises the output torque and the efficiency of the engine. Traditionally MBT timing is implemented as an open-loop control where the ignition timing is found by using a combination of static lookup tables and sensor information. READ MORE

  3. 2. Improved Experimental Agreement of Ionization and Pressure Peak Location by Adding a Dynamical NO-Model

    University essay from Institutionen för systemteknik

    Author : Daniel Claesson; [2004]
    Keywords : Technology; zonal models; combustion; ionization current; experimental verification; sensitivity analysis; dynamical NO-models; TEKNIKVETENSKAP;

    Abstract : Modelling combustion engines is an important tool in engine research. Development and modelling of ionization current has potential in developing virtual pressure sensors based on ionization measurements. READ MORE
