IPC: F02D41/34
Filed: 2002-09-13
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem in conventional correction to inter-cylinder irregularity, that the correction has been limited to that in idling states only without the execution of correction to inter-cylinder irregularity in other driving ranges (such as ordinary traveling of a vehicle), which leads to deterioration of exhaust gas performance and drivability.  <P>SOLUTION: An ECU 5 determines an actual crank angular speed ω for each cylinder and a reference crank angular speed ωSTD for each cylinder, determines a corrected valve opening time ε for each cylinder based on angular speed deviation Δω for each cylinder, and corrects a target valve opening time TQ for each cylinder. Inter-cylinder irregularity can thus be corrected for states of transition such as acceleration and deceleration as well as idling states. Inter-cylinder irregularity can thus be executed for any driving range. Exhaust gas performance and drivability can be improved for all the driving ranges.  <P>COPYRIGHT: (C)2004,JPO
