Title:
ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/069488
Kind Code:
A1
Abstract:
An engine control device that is able to reliably reduce the amount of soot in exhaust, and is capable of accurately detecting and reporting the fact that the amount of soot in exhaust has deteriorated (increased), is provided. By using a means for directly detecting the amount of soot in exhaust, the amount of soot in exhaust is accurately detected in real time, and when the amount of soot in exhaust deteriorates, engine control parameters (for example, fuel injection pressure) are altered (increased) so as to minimize the amount of soot in exhaust. Furthermore, if the discharge of soot cannot be suppressed even after performing such a processing operation, that fact is reported.
