| 20090063025 | METHOD AND DEVICES EQUIPPED WITH A HIGH-PASS FILTER FOR APPRAISAL OF THE KNOCKING IN EVERY CYLINDER OF AN INTERNAL COMBUSTION ENGINE - The invention relates to the field of methods and devices for evaluating the knocking inside every cylinder of an internal combustion engine by making advantageous use of the ionisation current generated during the combustion of the fuel in each cylinder of said engine. The invention develops over various phases, each of which is repeated continually for each cycle of said combustion engine and is characterised by the fact that ionisation current values are selected during determined lengths of time, and said values are entered in a high-pass filter, the values determined by said filter then being squared and the value Vd calculated, said value being the relation between the value of the sum of the squares of said values obtained by said filter and a known normalisation coefficient, thus generating the spark at the spark plug in each cylinder on the basis of said value Vd. | 03-05-2009 |
| 20090125210 | METHOD AND DEVICE FOR THE DETERMINATION AND INPUT OF FUEL INTO AN INTERNAL COMBUSTION ENGINE ON THE BASIS OF AN AIR-FUEL RATIO TARGET AND IONIC CURRENT SENSOR - The invention relates to the field of method and devices for determining and putting in fuel into an internal combustion engine on the basis of an air-fuel ratio in proximity to the stoichiometric value. The present invention is based on the use of the ion current released by a device, positioned on each cylinder of said engine. This ion current is acquired by a Control Unit equipped by means, preferably electronic ones, which implement the invention, repeated continually for each engine cycle and for each cylinder, characterized in that said method develops over various phases. | 05-14-2009 |
| 20090301177 | METHOD AND DEVICES TO IDENTIFY THE PISTON IN THE COMPRESSION PHASE IN AN INTERNAL COMBUSTION ENGINE EQUIPPED WITH A GASOLINE INDIRECT ELECTRONIC INJECTION SYSTEM - The invention relates to the field of method and devices therefore for identifying which cylinder is in the compression phase in a gasoline indirect electronic injection internal combustion engine. | 12-10-2009 |
| 20090326786 | METHOD AND DEVICES FOR THE CONTROL OF THE AIR-FUEL RATIO OF AN INTERNAL COMBUSTION ENGINE - The present invention fall into the field of methods and devices therefor for controlling the normalised air-fuel ratio of an internal combustion engine, otherwise known, in technical terms, as Lambda. The present invention is based on the use of the ionisation current released by a device positioned on each cylinder of said engine. This ionisation current is measured by a Control Unit equipped with a low-pass filter and electronic means which implement the invention. | 12-31-2009 |
| 20100064772 | METHOD AND DEVICES FOR THE IDENTIFICATION OF VARIOUS PHASES OF AN IONIZATION CURRENT SIGNAL DURING THE COMBUSTION IN AN INTERNAL COMBUSTION ENGINE - The present invention falls into the field of methods and devices for identifying the various phases of the ionization current during combustion in a cylinder of an internal combustion engine. | 03-18-2010 |
| 20100070157 | METHOD AND DEVICES TO REDUCE THE DIFFERENCE BETWEEN NORMALIZED AIR-FUEL RATIO OF THE VARIOUS CYLINDERS IN AN INTERNAL COMBUSTION ENGINE AND A PREDETERMINED VALUE - The invention relates to the field of methods and devices for reducing the difference between normalized air-fuel ratio of the various cylinders compared with a predetermined value between 0.7 and 1.1, of the normalized air-fuel ratio in an internal combustion engine. The method and devices utilize the signal of the ionization current produced by a suitable device, modifying the quantity of fuel on the basis of the signal determined by means of the method in question in the invention. | 03-18-2010 |
