    Sammanfattning : The current Spark Ignited (SI) engine equipped with three-way catalyst offers low emissions, but has low efficiency at part load, which results in unnecessarily high CO2 emissions. The Compression Ignited (CI) engines have higher efficiency and hence lower CO2 emissions, but suffer from higher Nitrogen Oxide (NOx) and Particulate Matter (PM) emissions, and no three-way catalyst can be used.
