<P>PROBLEM TO BE SOLVED: To provide an engine control device capable of maintaining satisfactory fuel consumption even in a transition state in which the combustion mode is changed. <P>SOLUTION: An ECU 100 sets temporary target valve timing θit', θet' for delaying convergence to the target valve timing θit, θet, and converges the valve timing θi, θe to the temporary valve timing θit', θet' when an engine operational state (the engine speed Ne, the intake air volume Gn) is present in a discontinuous area A in which the valve timing θi, θe during the transition state of convergence to the target valve timing θit, θet can pass the valve timing area B of poor fuel consumption, and the present valve timing θi, θe are located far from the valve timing area B of poor fuel consumption when viewed from the target valve timing θit, θet sides. <P>COPYRIGHT: (C)2012,JPO&INPIT |
