Provided are an engine valve control method and an engine valve control apparatus while fuel cut-off driving controls an air intake valve and an exhaust valve in accordance with an engine stroke to minimize a pumping loss by using electronic cam variable valve timing (E-CVVT) during fuel cut-off driving. The provided engine valve control apparatus during fuel cut-off driving determines the engine stroke based on a position of a crank and a position of a cam, controls both the air intake valve and the exhaust valve to be opened in an intake stroke and an explosion stroke, and controls only the exhaust valve to be opened in a compression stroke and an exhaust stroke when the engine valve control apparatus determines that a vehicle state accesses a fuel cut-off mode of a vehicle based on a vehicle state and blocks fuel supply to an engine while fuel cut-off driving. COPYRIGHT KIPO 2016 (110) Fuel cut-off determination unit (120) Fuel cut-off control unit (130) Crank position sensing unit ( ...
