Pre-ignition estimation/control device for an internal combustion engine |
摘要 |
A pre-ignition estimation/control device includes: an octane number estimation module for estimating an octane number of a fuel based on detection signals received from an intake air temperature sensor, a water temperature sensor, etc; a pre-ignition-occurrence-index calculation module for calculating a pre-ignition occurrence index based on the estimated octane number and the like; a pre-ignition-occurrence-index correction module for correcting the pre-ignition occurrence index so as to cause the pre-ignition more likely to occur; an effective-compression-ratio-boundary calculation module for calculating a boundary of an effective compression ratio based on the pre-ignition occurrence index; an intake-cam-phase-advance calculation module for calculating a phase advance of an intake cam based on the boundary of the effective compression ratio and the like; and an intake-cam-phase control module for controlling an intake-cam variable phasing system based on the phase advance of the intake cam, to thereby restrict a change in phase advance. |
