KNOCKING CONTROL METHOD AND APPARATUS FOR INTERNAL COMBUSTION ENGINE |
摘要 |
For suppression of knocking in an internal combustion engine, an engine vibration level is periodically generated at predetermined time intervals on the basis of an output signal of a knocking sensor which is installed for detecting the engine vibration, the engine vibration level thus generated being compared with a preset sensor failure level. When the vibration level remains lower than the preset sensor failure level successively throughout a period corresponding to a predetermined number of engine cycles, a knocking sensor failure indication signal is generated to thereby allow knocking control to be precautionarily performed for the safety of the engine operation.
