Abstract

The invention relates to a control method of a cylinder deactivation and an engine to which the same is applied. The engine includes: a duration apparatus for adjusting an opening duration of an intake valve, a Cylinder De-Activation (CDA) apparatus for controlling deactivation of an exhaust valve, an igniter, an injector for injecting a fuel, an operation state signal unit for measuring an operation state of a vehicle, and a controller for controlling the operations of the duration apparatus, the CDA apparatus, the igniter, and the injector based on an output signal from the operation state signal unit. A control method for this engine includes: determining, by the controller, whether the operation state of the vehicle corresponds to a CDA operation mode; and when the CDA operation mode is determined, operating the CDA apparatus so as to stop the operations of the igniter and the injector, increase an opening duration of the intake valve, and deactivate the exhaust valve by controlling the CDA apparatus.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2019-0113033 filed on September 11, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a control method for cylinder deactivation and an engine applying the method. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Internal combustion engines generate power by burning fuel in a combustion chamber in the medium of air drawn into the combustion chamber. The intake valves are operated by the camshaft to draw in air and draw air into the combustion chambers when the intake valves are open. In addition, the exhaust valve is operated by the camshaft, and combustion gas is discharged from the combustion chamber while the exhaust valve is opened. ...
