Abstract
Official abstract text for this publication.
Knocking and pre-ignition are identified, without contributing to pre-ignition, even when vibration magnitudes and timings of occurrence of the knocking and pre-ignition are the same. When detecting an abnormal combustion that cannot be identified as a knocking or pre-ignition, ignition timing is advanced, at which time knocking is identified when an abnormal combustion intensity increases, and pre-ignition is identified when a difference between ignition timing and abnormal combustion occurrence timing increases.
First claim
Opening claim text (preview).
What is claimed is: 1. An internal combustion engine abnormal combustion detection device, comprising: a driving state detection device that detects a driving state of an internal combustion engine; and a control device that controls the internal combustion engine based on an output signal from the driving state detection device, wherein the control device includes an ignition timing controller that controls an ignition timing in accordance with the driving state, a crank…
