Air Charge Estimation in Turbocharged Spark Ignition Engines
Turbocharged (TC) spark-ignited (SI) engines are popular as they combine high power output with good fuel economy. Furthermore, their emissions can be successfully reduced using a three way catalyst (TWC) provided that the airfuel ratio is precisely controlled. As the air-fuel ratio depends on the precision of the air charge estimate, this thesis is devoted to the systematic improvement of the ...
متن کاملAlternative Fuels for Spark Ignition Engines
In order to reduce the atmospheric pollution emitted by automobiles, control devices are being incorporated in the vehicles in many countries. This has resulted in a reduced vehicle mileage to the extent of about fifteen percent. Without the introduction of new technology, any further reduction in emission levels would be expected to extract payment in the form of further fuel economy losses. I...
متن کاملInjector Characteristics Estimation for Spark Ignition Engines
Injector characteristics estimation is an essential ingredient for an effective automotive engine control system. An accurate estimation algorithm is presented in this paper, Simulation and experimental results are provided to demonstrate the quality of the algorithm.
متن کاملCold start modelling of spark ignition engines
The ability of mean value models to replicate the key characteristics of automotive powertrains has been well established over the past four decades. There has been considerable success in the application of these models to controller design, with improved emissions and performance of the primary benefits. However, these low order models typically must make certain assumptions about the engine—...
متن کاملPre-ignition in Highly Charged Spark Ignition Engines – Visualisation and Analysis
Highly boosted spark ignition engines must confront violent forms of pre-ignition limiting the maximal low-end torque. French research institute IFP presents here an innovative tool allowing a better understanding of this phenomenon and a structured reasoning considering all potential causes of this phenomenon. Advanced statistical analyses of the combustion process and direct visualisations in...
