Full textAbstract
Abstract The reason to measure the ion current in a combustion engine is to extract combustion parameters in order to achieve closed loop control of the combustion i.e. control of the spark, fuel and air into the engine. By using the spark plug, in a spark-ignited engine, as a probe it is possible to measure the ion current.
The purpose with this thesis is to improve an existing ion current interface.
A ringing caused by the ignition coil will follow by the ion current signal. Now the need of energy in the spark increase. Since increased energy in the spark gives a longer burn time and a longer ringing the ringing will extend into the ion current signal. The problem with the old interface is that the ringing is not symmetrical which could cause problems when filtering the signal.
The aim of this thesis is to achieve a symmetrical ringing and a interface that can handle an ion current amplitude from 0,1µA to 1mA.

Full textAn effective way to extract combustion parameters from a spark ignited engine is to measure the level of ionization. One way to do this is to use the spark plug as a sensor.
Until now this has been achieved by applying a DC voltage over the spark gap which causes an electrical field. The electrical field together with the ionization process gives cause to an ion current which can be measured and analyzed. Previous research suggests that it would be beneficial to replace the DC voltage with an AC voltage.
The focus in this thesis is on the hardware and how to best implement an AC voltage to the existing ion sensing system. Both simulation- and hardware models will be constructed. These models will be tested and analyzed to evaluate both benefits and drawbacks of an AC ion current sensing system.

Full textThis masters thesis investigates the possibility to estimate the ethanol content in the fuel using ion currents. Flexible fuel cars can be run on gasoline-ethanol blends with an ethanol content from0 to 85 percentage. It is important for the engine control system to have information about the fuel. In todays cars the measurements of the fuel blend are done by a sensor. If it is possible to do this with ion currents this can be used to detect if the sensor is broken, and then estimate the ethanol content until the sensor gets fixed. The benefit
of using ion currents is that the signal is measured directly from the spark plug and therefore no extra hardware is needed. To be able to see how the ethanol ratio affects the ion currents, the dependencies of the operating point have been investigated. This has been done by a literature review and by measurements in a Saab 9-3. Engine speed, load, ignition timing, lambda and spark plugs effects on the ion currents are especially studied. A black box model for the ion currents dependence on operating point is developed. This model describes the engine speed, load and ignition timing dependencies well, but it can not be used to estimate the ethanol ratio.

Full textPå senare tid har behovet av batterier av Li-jontyp ökat kraftigt inom ett flertal applikationsområden inkluderande portabel elektronik, elfordon och miljövänlig elenergiproduktion. I dessa applikationsområden behövs en högeffektiv laddstrategi för att möjliggöra ett stort antal cyklingar av batterierna. Nyligen har en new laddmetod, benämnd sinusoidal ripple current-constant voltage-laddning (SRC-CV-laddning) föreslagits och har i vissa publikationer demonsterat en förbättring av laddprestanda hos Li-jonbatterier jämfört med konventionell constant-current constant-voltage-laddning (CC-CV-laddning). I detta examensarbete undersöks laddprestandan hos SRC-CV och CC-CV-laddning när de appliceras på prismatiska Li-jonceller avsedda för traktionsdrift. En existerande experimentuppsättning har uppgraderats för att realisera laddcykling med SRC-CV-laddning. Med hjälp av elektrokemisk impedansspektroskopi på tre Li-jonceller har den frekvens vid vilken magnituden på cellernas impedans är minimerad identifierats. Nyckelparametrar såsom laddtid, urladdningstid och energieffektivitet har uppmätts för både SRC-CV- och CC-CV-laddning. De experimentella resultaten visar ingen signifikant förbättring mellan SRC-CV-laddning (implementerat med en konstant rippelströmfrekvens) och konventionell CC-CV-laddning.
