One or the phase method of detection which uses the lambda value change in the plural cylinders

摘要

This invention is operated making use of the engine management system, even number or regards the method for the phase identification of the Taki tube internal combustion engine of the high tension ignition type where odd number has number of cylinders. Operational cycle of the internal combustion engine has been present, the output axis extending to 2 revolutions at least, extending. The internal combustion engine, when phase position is unknown, is started in the origin of the pickup of one phase position. Control of intervention to the mixture formation which relates to diluting or thickening the mixture one where the internal combustion engine is selected or regarding the plural cylinders is done. On the basis of the detection and change of excess air factor , first authenticity of the phase position which the pickup is done is verified when starting the internal combustion engine. When phase position it is verified, as the fake urgent operation of the internal combustion engine having with double ignition output, it is maintained, or or is synchronized anew, or is for the second time synchronized.
