Abstract

Official abstract text for this publication.

There is provided an internal combustion engine control apparatus that can more accurately calculate a volume efficiency correction coefficient and can more accurately estimate the amount of air that flows into a cylinder and the external exhaust gas recirculation amount. In an internal combustion engine provided with an exhaust gas recirculation apparatus including an exhaust gas recirculation valve and an exhaust gas recirculation path, based on a cylinder flow rate, an exhaust gas recirculation amount, an inner-intake-pipe density, and an inner-intake-pipe density changing amount, a volume efficiency correction coefficient, as a volume efficiency corresponding value, is calculated; then, by use of the calculated volume efficiency correction coefficient, a cylinder intake air amount and a recirculation amount of exhaust gas that is taken into the cylinder are calculated.

First claim

Opening claim text (preview).

What is claimed is: 1 . An internal combustion engine control apparatus comprising: an intake air amount detection unit that detects an amount of air that passes through a throttle valve provided in an intake pipe of an internal combustion engine and is taken into the internal combustion engine; a volume efficiency corresponding value calculation unit that calculates a volume efficiency corresponding value as an index that indicates an amount of air that flows from the intake…
