Title:
INTAKE AIRVOLUME CONTROLLER OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2005/003534
Kind Code:
A1
Abstract:
An intake air volume controller of an internal combustion engine in which variation in the intake air volume can be corrected appropriately among cylinders and both operability and exhaust gas characteristics can be enhanced even in a normal operating load area including a high load area. The ECU (2) in the intake air volume controller (1) of an internal combustion engine (3) controlling the intake air volume of four cylinders &num 1-&num 4 independently through a variable phase mechanism (80) between intake cams identifies an intake air volume variation coefficient (Φ&num i) such that an estimated value (Gth&lowbar est) matches a TH passing intake air volume (Gth) based on a model [formula (43)] defining the relation of the estimated value (Gth&lowbar est) of TH passing intake air volume and a plurality of simulation values (Gcyl&lowbar 0S&num i), calculates, for each cylinder, a target phase between intake cams (Ѳssi&num i&lowbar cmd) depending on the identified intake air volume variation coefficient (Φ&num i) (step 81), and calculates control inputs (DUTY&lowbar ssi&num 2-&num 4) to the variable phase mechanism (80) between intake cams depending on the target phase between intake cams (Ѳssi&num i&lowbar cmd) (step 75).
