| 摘要 |
The present patent application refers to particular upper level key parameter definitions for a logical sensor for Internal Combustion engines (Compression Ignited or Spark Ignited working in Controlled Auto Ignition mode) named SBS (Software Biodiesel Sensor), which identifies a base-fuel/bio-fuel mixture present in a vehicle fuel tank, using software-based algorithms to identify the fraction of FAME (Fatty Acid Methyl Esters) vegetal-based oil or oil produced from organic waste blended into a crude oil based diesel fuel (average chemical formula C12H23) and thereafter adapts the engine control strategy as a function of this fraction. Furthermore, the defined upper level key parameter set can be used to detect or enhance the detection of a specific type of FAME vegetal-based oil or oil produced from organic waste used in the blend (e. g. soya bean, palm oil or other) used as baseline biofuel.
