摘要： A knock detecting apparatus for an internal combustion engine includes a vibrating sheet branched into a plurality of vibrating reeds by forming a recess from one end of the vibrating sheet. The vibrating reeds have different lengths, shapes or thicknesses, and the other end of the vibrating sheet is fixed to a supporting member which is secured to the engine thereby to allow the vibrating reeds to vibrate with different resonance characteristics in response to the vibration of the engine caused by the knocking. The vibration of the vibrating sheet is detected, for example, as a change in reluctance by forming a magnetic path through the vibrating sheet and air gaps respectively located between the free ends of the vibrating reeds and a core.

摘要： A knock detecting apparatus for an internal combustion engine includes a vibrating reed of magnetic material. One end of the vibrating reed is fastened to a supporting member interposing therebetween a magnet and one end of a core. The free end of the vibrating reed confronts with the other end of the core with an air gap therebetween to form a magnetic path including the magnet, vibrating reed, air gap and core. As the vibrating reed vibrates in response to vibration of the engine on which the supporting member is securely mounted, the distance of the air gap changes causing a change in magnetic flux passing through the magnetic path. The change of magnetic flux is detected by a coil wound on the core. The resonance characteristic of the vibrating reed is arranged to fall in the frequency range of the knocking.

摘要： A vibrator having a resonant frequency within a knocking frequency range forms a part of a magnetic path. The vibrator vibrates in response to the vibration of an internal combustion engine and this changes the reluctance of the magnetic path. The change in the reluctance is sensed by a coil to detect the presence of knock. The vibrator is enclosed with a damper substance consisting of a liquid or sol substance having viscosity of flow properties so that the vibration of the vibrator is restricted and the Q of the resonance characteristic of the vibrator is deteriorated, thus increasing the substantial range of frequency detection of the apparatus. If necessary, the damper substance is heated to maintain its viscosity at a predetermined value.

摘要： A knock detecting apparatus for detecting the occurrence of knocking in an internal combustion engine by detecting variations in the pressure of engine cooling water. A sealed double diaphragm structure is formed by a first diaphragm which is directly responsive to variations in the cooling water pressure and not resonant at the knock frequencies and a second diaphragm which is resonant at the knock frequencies. A noncompressible fluid is contained in the sealed double diaphragm structure between the two diaphragms. Pulsations of the second diaphragm, resonant at the knock frequencies, are detected by a magnetic device or a piezoelectric device operative to output an ac signal.
