摘要： A traverse shaft section (609) shifts in response to the rotation of a bobbin rotating section (604) with a predetermined winding pitch P1 equivalent to two to 10 times of the diameter of a wire rod (520). With this shift movement of traverse shift section (609), wire rod (520) extracted from a winding nozzle section (610) shifting together with traverse shaft section (609) is wound spirally along a slant surface (530) formed by a first winding section (541) at the winding pitch P1 equivalent to two to 10 times of the diameter of a wire rod (520). As a result, an advancing-side wire rod (520a) and a reversing-side wire rod (520b) cross over each other at opposing inclinations. Hence, it becomes possible to prevent the reversing-side wire rod (520b), when wound on the advancing-side wire rod (520a), from pulling and dislocating the advancing-side wire rod (520a) from its regular winding position, thereby eliminating undesirable winding collapse.
摘要翻译：横动轴部分（609）响应筒管旋转部分（604）的旋转以相当于线材（520）直径的2至10倍的预定卷绕间距P1移动。通过横移移位部（609）的移动移动，从与横动轴部（609）一起移动的卷绕喷嘴部（610）抽出的线材（520）沿着由第一卷绕部（541）以相当于线材（520）的直径的2至10倍的卷绕间距P1。结果，在相反的倾斜处，优先侧线材（520a）和反转侧线材（520b）彼此交叉。因此，当前行线520a被缠绕时，可以防止反转侧线520a从前侧侧线520a偏离其正常绕线位置，由此消除不必要的缠绕塌陷。

摘要： An ignition and engine control system for an internal combustion engine. The system includes a flyback ignition transformer which can rapidly re-fired a spark plug during a combustion cycle to perform various ignition diagnostic procedures using the spark plug as a feedback element of the control system. The transformer is adapted for mounting directly to a spark plug and includes a core about which a primary and secondary are toroidally wound. A controller provides signals to a circuit which causes maximum charging of the transformer for ignition and subsequent charging of the transformer for diagnostic purposes. The system also includes a diagnostic circuit which can detect the occurrence of an electrical discharge, and/or its duration, across the spark plug as a result of one of the diagnostic charges by monitoring the transformer for a reflected voltage in its primary. The detection circuit outputs a signal to the controller which allows the controller to diagnose conditions within the combustion cylinder.

摘要： A method for detecting misfire in the combustion cylinder of a spark ignition internal combustion engine. The method includes the steps of charging an ignition transformer to a maximum ignition charge and initiating an ignition discharge between electrodes of the spark plug. The ignition transformer is then charged to a predetermined diagnostic charge which is less than said maximum ignition charge. If combustion is occurring within the cylinder, the temperature and pressure near the spark plug will be sufficient to allow the diagnostic charge to discharge. If the diagnostic charge does not discharge, the charge will be reflected back into the ignition transformer where it will be detected by a circuit as an indicia of misfire. Further also detection of autoginition, preignition and engine load. Use is made of special CPP ignition transformers which are able to refire at short intervals. Multispark ignition applied during hard engine operating conditions e.g. cold starting.

摘要： A method for determining engine load of a spark ignition internal combustion engine. The method includes the steps of charging an ignition transformer to a maximum ignition charge and initiating an ignition discharge between electrodes of the spark plug. The ignition transformer is then charged to a predetermined diagnostic charge which is less than said maximum ignition charge. The diagnostic charge is discharged at a time of the combustion cycle where pressure in the combustion cylinder is dependent on engine load. The duration diagnostic discharge is then monitored and subsequently correlated to engine load. In this manner, the spark plug is used as a feedback element in determining engine load. Further also detection of misfire, autoignition and preignition. Use is made of special CPP ignition transformers which are able to refire at short intervals. Multispark ignition applied during hard engine operating conditions e.g. cold starting.

摘要： An engine ignition and control system for an internal combustion engine. The system includes an ignition transformer mounted to a spark plug and adapted to rapidly re-fire the spark plug during a combustion cycle enabling e.g. multispark ignition during adverse engine operating conditions and here the performance of various engine diagnostic procedures. A controller provides a signal to an ignition circuit which causes the transformer to charge for ignition and subsequently charge for performing diagnostics. The system also includes a diagnostic circuit, connected to the transformer, which can detect the occurrence of an electrical discharge across the spark plug electrodes as a result of one of the diagnostic charges. The detections circuit either outputs a signal to the controller or omits the signal to the controller. This allows the controller to diagnose conditions within the combustion cylinder such as autoignition, misfire, preignition or load.
