VARIABLE VALVE TIMING CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE AND INTERNAL COMBUSTION ENGINE INCLUDING VARIABLE VALVE TIMING CONTROL APPARATUS

摘要

As for a reference valve timing varying rate A obtained by a deviation Deltaphi between a target VVT phase phiT and an actual VVT phase phi, when a varying rate Deltathetath of an accelerator opening degree resulting from the manipulation of the driver is relatively low, a VVT-ECU places a limit on the valve timing varying rate. When the varying rate Deltathetath of the accelerator opening degree is relatively high, it varies the valve timing with the reference valve timing varying rate A.
