Document Type and Number:
Japanese Patent JP4036057
Kind Code:
B2
Abstract:
A controller controls an intake air quantity in accordance with valve timings of the intake valve determined according to the operational angle through the cam operational angle variable mechanism and the phase through the cam phase variable mechanism, the controller determining an allowable residual gas quantity from a required air quantity and an engine speed, the required air quantity being determined according to a manipulated variable of an accelerator, calculating optimum intake valve open and closure timings (IVO and IVC) in such a manner that both of the required air quantity and the allowable residual gas quantity enter a cylinder of the engine, and determining the operational angle and the phase from the optimum intake valve open and closure timings.
