Publication number: 20120053815Abstract: 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.Type: ApplicationFiled: August 4, 2011Publication date: March 1, 2012Applicant: Magneti Marelli Sistemas Automotivos Industria e Comercio LtdaInventors: Gino MONTANARI, Michael PONTOPPIDAN

Patent number: 6443119Abstract: The invention concerns a combustion chamber delimited by a piston head having, inside a planar peripheral ring, a recess in the form of a concave bowl open towards the chamber and off-center on the piston axis (X—X) side which faces towards the injector inclined on the axis (X—X) and is laterally implanted on the cylinder head for direct injection into the chamber, and on the axis (X—X), a boss having, in layout, a horseshoe or crescent shape which partially enclosed the recess. The boss has an overhanging edge above the connection between the recess and the boss, whereof the upper surface is convex towards the chamber. The width of the overhanging edge is at its maximum in the horseshoe shaped boss base and gradually decreases until it substantially disappears at the tips of the two wings of the horseshoe-shaped boss, thereby ensuring a good preparation for the air/fuel mixture in the center of the chamber, opposite the axial plug at the chamber top.Type: GrantFiled: February 8, 2001Date of Patent: September 3, 2002Assignee: Magneti Marelli FranceInventor: Michaël Pontoppidan
