A variable valve control apparatus includes a variable valve timing
mechanism that adjusts an actuation timing of an intake valve and an
actuation timing of an exhaust valve; a variable working angle mechanism
that adjusts a working angle of the intake valve; a variable valve
control section that controls at least one of the variable valve timing
mechanism and the variable working angle mechanism based on an engine
load; and a negative pressure suppression control section. The negative
pressure suppression control section suppresses a negative pressure of an
inside of a cylinder when the negative pressure suppression control
section determines that both of the intake valve and the exhaust valve
close after an intake top dead center, based on opening conditions of the
intake valve and the exhaust valve.
