摘要： PROBLEM TO BE SOLVED: To provide a current cut-off type internal combustion engine ignition method which can prolong a life of an ignition plug. SOLUTION: When a set discharge duration passes after a primary current of an ignition coil 1 is cut off at an ignition position of internal combustion engine, a switch 2 for primary current control is made conductive and current is made to flow in the primary coil 1a of the ignition coil from a battery 3, thereby carrying out a discharge stop process for stopping discharge generated in the ignition plug 10. After discharge generated in the ignition plug is stopped, the conductive state of the switch 2 for primary current control is shifted to a cut-off state while gradually increasing internal resistance of the switch, and the cut-off state of the switch for primary current control is held till a next energization starting position is reached.

摘要： PROBLEM TO BE SOLVED: To provide an ignition device capable of having the function to prevent the reversing of an engine without reducing the load driving performance of a generator when the engine runs at a low speed. SOLUTION: A voltage comparator CP output of which becomes a zero level and a high level respectively when a magneto coil 1 generates a positive half-wave output voltage and when the magneto coil generates a negative half- wave output voltage, and a transistor TR3 which conducts when output of the comparator CP is at a high level, to prevent output of a signal coil 2 from being given to a CPU 5, are provided. When the engine is forward operated, and when the transistor TR3 is shut-off, the CPU allows the signal coil 2 to generate a signal to perform igniting operation successfully. When the engine is reversely operated and the transistor TR3 is in a state of electrical continuity, the CPU allows the signal coil 2 to generate a signal to prevent output of the signal coil from being given to the CPU, and thus to stop the igniting operation.

摘要： PROBLEM TO BE SOLVED: To improve ignitability to a mixture and to prevent a misfire caused by the fouling of a plug by switching-driving a switching element continuously a plurality of times to generate spark discharge to a spark plug continuously a plurality of times at the combustion timing of one combusiton cycle of an internal combustion engine. SOLUTION: At the time of operating an engine, a control signal generated by an ECU so as to generate spark discharge to a spark plug 13 continuously a plurality of times is impressed to a transistor 17 which is a switching element, to switch-drive it. With the 'on' operation of the transistor 17, a primary current flows to a primary coil of an ignition coil, and the primary current is cut off by the succeeding 'off' operation. High voltage is thereby generated to a secondary coil of the ignition coil to generate spark discharge at the spark plug 13. Such operations are repeated a plurality of times, and multiple discharge is generated by recarrying the primary current before the natural termination of spark discharge. A mixture is thereby ignited positively.

摘要： PROBLEM TO BE SOLVED: To enhance heat efficiency and reduce emission by providing a pre- reaction detecting means for detecting the pre-reaction restart time of combustion, and applying auxiliary energy for activating ignition by an auxiliary energy applying means during the pre-reaction period of combustion detected by the above meas. SOLUTION: A compression self-igniting combustion engine is provided with a combustion pattern characteristic of once making pre-reaction near the piston top dead center of the compression stroke, and then causing main combustion in the expansion stroke. When external ignition energy amount is suitably increased during the pre-reaction period, the pre-reaction is activated more to transfer the peak point of main combustion near the piston top dead center of the expansion stroke, thereby optimizing heat efficiency. A combustion chamber 4 is provided with an auxiliary energy applying means 12 formed by an ignition plug or the like. and during the pre-reaction period of combustion detected by the pre-reaction detecting means, a proper amount of auxiliary energy is applied by the auxiliary energy applying means 12 to activate pre- reaction.

摘要： PROBLEM TO BE SOLVED: To prevent defects, including occurrence of quenching when energized too short or wearing out of the electrodes of spark plug when energized too long, by detecting the in-cylinder pressure with an in-cylinder pressure sensor and determining the optimum energized time on the ignition coil according to these detection signals. SOLUTION: While an engine 1 is running, an in-cylinder pressure sensor 17 takes a sample of an in-cylinder pressure in the cylinder two cylinders in advance. At starting, the in-cylinder pressure at the previous time stored in RAM is read. An average effective pressure is calculated from the in-cylinder pressure, and the energized time is retrieved with a map based on the average effective pressure. While, ignition timing is determined by the negative pressure in an intake manifold 5 and the engine speed, and then energizing start timing to be given as the ignition advance value is determined by the energized time to an ignition coil 13, the ignition timing, and the engine speed. Thus, ignition is executed with the optimized energized time according to the in-cylinder pressure, preventing air pollution and making the life of the ignition plug longer.

摘要： PROBLEM TO BE SOLVED: To perform ignition certainly even though an ignition coil of small inductance is in use. SOLUTION: An ignition device for an internal combustion engine is of spark type consisting of an ignition coil 10 and is composed of an ignition plug connected to the secondary winding 14 and an electricity supplying circuit coupled with the primary winding 12 of the ignition coil 10 including a semiconductor device 16 controlled by an electronic control unit 18 which is programmed so that the charging cycles are generated in the process wherein the momentary current flowing in the primary winding 12 increases gradually from the min. to max. value followed by quick return to the minimum value. The electronic control unit 18 is programmed so as to generate one continuous charging cycle during the same engine cycle. Each charging cycle is separated from the preceding charging cycle with a time interval having a duration longer than that of the discharge cycle.
