摘要： An insulator includes a coil side cylindrical portion extending from a plug side cylinder portion in a direction departing from a combustion chamber. One end of the coil side cylindrical portion protrudes in the direction departing from the combustion chamber with respect to a primary winding and a secondary winding. A pressure sensing element is disposed next to the one end of the coil side cylindrical portion. The signal lines of the pressure sensing element are taken out of a casing without passing aside an ignition coil. Thus, the diameter of the casing does not increase. The output signal of the pressure sensing element is not adversely influenced by discharge noises generated from the ignition coil.

摘要： An apparatus for detecting a condition of burning in an internal combustion engine includes a pair of opposed electrodes provided in a combustion chamber of the engine, and an AC voltage applying device for applying an AC voltage between the opposed electrodes. A current detecting device is operative for detecting a current flowing between the opposed electrodes. A current generating means for generating a current-representing signal depending on the detected current, the current generating means having a differentiating circuit for differentiating the AC voltage into the capacitance-current representing signal. In another aspect of this invention, the apparatus further comprises calculating means for calculating ratios between a parameter represented by the burning-ion current representing signal and a parameter represented by a signal depending on the AC voltage applied between the opposed electrodes. A waveform processing device is operative for removing the capacitive current component from the current-representing signal to extract a burning ion current component, and for generating a burning-ion-current representing signal depending on the extracted burning ion current component. The capacitive current component occurs in correspondence with the AC voltage. One aspect of the invention utilizes calculating means for calculating a ratio between a parameter represented by the burning-ion-current representing signal and a parameter represented by a signal depending on the AC voltage applied between opposed electrodes. The burning ion current component corresponds to a burning ion current which flows between the opposed electrodes. A burning condition detecting device is operative for detecting a condition of burning in the combustion chamber of the engine on the basis of the burning-ion-current representing signal generated by the waveform processing device. The waveform processing device includes an integration processing device for integrating the current-representing signal to generate the burning-ion-current representing signal.

摘要： A combustion monitoring apparatus for an internal combustion engine is provided which includes a voltage supply circuit, a combustion monitoring circuit, and a control circuit. The voltage supply circuit applies the voltage to plug electrodes of a spark plug mounted in a combustion chamber of the engine. The combustion ion monitoring circuit monitors a variation in amount of combustion ions existing between the plug electrodes to determine a combustion condition of the engine based on the current flowing through the plug electrodes produced by application of the voltage to the electrodes. The control circuit controls an operation of the voltage supply circuit so that the voltage is applied across the plug electrodes prior to a discharge duration of a spark plug mounted in the combustion chamber of the engine for monitoring preignition.

摘要： A combustion condition detecting device detects combustion ions between opposing electrodes in a combustion chamber by ion current flowing between the electrodes in response to a.c. current voltage applied between the electrodes. A low pass filter for eliminating current components having high order frequencies of the a.c. voltage is disposed in a primary side of the transformer so that a waveform of the a.c. voltage approximates a sine wave. Thus, detection accuracy of the combustion ions is prevented from being affected by variation of capacitive current included in the current flowing between the electrodes, wherein the variation of the capacitive current is caused by distortion of the waveform of the a.c. voltage.
