Title:
DEVICE FOR CALCULATING INTAKE AIR VOLUME IN CYLINDER OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2010/095477
Kind Code:
A1
Abstract:
Provided is a device for calculating the intake air volume in a cylinder wherein the intake air volume, i.e. the volume of fresh air to be taken into the cylinder of an internal combustion engine is calculated. The intake air flow rate, i.e. the flow rate of fresh air passing through the intake passage of an engine is acquired and the intake air temperature and intake air pressure are detected. The theoretical intake air volume in a cylinder is calculated based on the intake air pressure, intake air temperature and cylinder volume, and the volume efficiency is calculated by dividing the intake air volume in a cylinder which is calculated previous time by the theoretical intake air volume in the cylinder. The intake air volume in a cylinder is calculated using the intake air temperature, intake air pressure, volume efficiency, intake air flow rate, and intake air volume in the cylinder calculated previous time.
