摘要： PROBLEM TO BE SOLVED: To provide an ignition device for an internal combustion engine capable of surely avoiding a runaway in an igniter even if an excess current is generated as the result of a failure inside the igniter.
SOLUTION: The ignition device 1 for an internal combustion engine uses an igniter 4 to control a current passed from a battery power source 5 to a primary coil 31 of an ignition coil 3. When an ignition control signal is inputted from an engine control unit 2 to a base 41B of a power transistor 41 that the igniter 4 has, a current is controlled to be either passed or shut between a collector 41C and an emitter 41E. The emitter 41E of the power transistor 41 is electrically connected to an emitter connection element 8 via a fuse element 7, so that when a large current flows between the collector 41C and the emitter 41E of the power transistor 41 and generates an abnormally high temperature, the fuse element 7 is fused and the power transistor 41 stops operating.

摘要翻译：要解决的问题：提供一种内燃机的点火装置，其能够确保避免点火器中的失控，即使由于点火器内的故障而产生过量电流。解决方案：用于内燃机的点火装置1使用点火器4来控制从电池电源5流到点火线圈3的初级线圈31的电流。当从发动机输入点火控制信号时控制单元2连接到点火器4具有的功率晶体管41的基极41B，电流被控制为在集电极41C和发射极41E之间通过或关闭。功率晶体管41的发射极41E通过熔丝元件7电连接到发射极连接元件8，使得当大功率晶体管41的集电极41C与发射极41E之间流过大电流时，产生异常高温，熔丝元件7熔断，功率晶体管41停止工作。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an igniter of an ignition coil for an internal combustion engine, preventing excessive current from being intermittently led to flow into the ignition coil for the internal combustion engine when a power transistor is short-circuited and the igniter is continuously energized.
SOLUTION: This igniter 1 of the ignition coil for the internal combustion engine is provided with the power transistor 4 controlling current-carrying state or non-current-carrying state of primary current flowing in the primary coil 31 of a coil-iron core assembly 3, according to an ignition control signal from an engine control device 2. A nonlinear type with an electric resistance value suddenly risen when exceeding 150°C is employed as a PTC thermistor 5 with the electric resistance value increased in association with temperature rise, and is arranged in a portion in the vicinity of the power transistor 4 and between the primary coil 31 and the collector portion 41 of the power transistor 4 connected to the primary coil 31.
