Abstract
A system and a method to control torque during a mode transition in an internal combustion engine with a fully variable intake valve is disclosed. The mode transition may be a change in the number of active cylinders in a variable displacement engine, a change in compression ratio in a variable compression ratio engine, a gear change in a transmission coupled to the engine, a traction control event, and a rapid change in driver demand.
