USAGE OF AN ESTIMATED DELIVERY-RATIO FACTOR FOR THE ERROR MONITORING IN AN AIR SYSTEM

摘要

PURPOSE: A usage of an estimated delivery-ratio factor for monitoring the error of an air system is provided to check the error of an engine system by using a delivery ratio. CONSTITUTION: An error monitoring apparatus monitors the error of an engine system(2) having an internal combustion engine(4) by using an estimated delivery-ratio factor. The engine system supplies air to the internal combustion engine as a delivery ratio. The delivery ratio indicates that actual air volume rate proportionally occupies in proportion to the ideal and theoretically air of the internal combustion engine. The error monitoring apparatus monitors the error of the engine system according to the delivery ratio.
