Document Type and Number:
Japanese Patent JPH04503387
Kind Code:
A
Abstract:
FID. 1 illustrates a system for monitoring and/or controlling engine performance of an engine (10) having multiple separate cylinders (12-15) each sequentially providing a driving force to a common mechanical member (16). The system comprises: sensor means (41) for monitoring the position of said driven member (16) and developing a speed-indicative signal (80, 81) indicative of and varying in accordance with the speed at which said driven member (16) is driven by said multiple cylinders (12-15); means (30) for monitoring a predetermined portion of said speed-indicated signal, said monitored portion generated in association with and during an expected power cycle produced by a first one of said cylinders and prior to an expected next sequential power cycle of another one of said cylinders; and means for developing a signal indicative of the occurrence of knock in said first one of said cylinders by determining when variations of said monitored portion of said speed-indicative signal match expected variations of said monitored speed-indicative signal which exist when knock in said first cylinder is present.
