METHOD AND DEVICES TO REDUCE THE DIFFERENCE OF THE NORMALIZED AIR-FUEL RATIO OF THE VARIOUS CYLINDERS IN AN INTERNAL COMBUSTION ENGINE COMPARED WITH A PREDETERMINED VALUE BETWEEN 0.7 AND 1.1, OF A NORMALIZED AIR-FUEL RATIO IN AN INTERNAL COMBUSTION ENGINE |
摘要 |
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. |
