Abstract
An apparatus and method for controlling deactivation of cylinders in an engine may include a sensor that measures pressure inside an intake manifold of the engine, an oil control valve (OCV) that deactivates the cylinders in the engine, and a controller that is configured to control the OCV to deactivate a specific cylinder in the engine, based on the pressure inside the intake manifold.
Claims20
An apparatus for controlling deactivation of cylinders in an engine, the apparatus comprising:
- a sensor configured to measure pressure inside an intake manifold of the engine;
- an oil control valve (OCV) configured to deactivate the cylinders in the engine;
- and
- a controller configured to control the OCV to deactivate a predetermined cylinder among the cylinders in the engine, based on the pressure inside the intake manifold.
A method for controlling deactivation of cylinders in an engine, the method comprising:
- setting, by a controller, a plurality of reference ranges and a number of the cylinders to be deactivated for each reference range of the plurality of reference ranges;
- obtaining, by the controller, pressure inside an intake manifold of the engine;
- and
- determining, by the controller, the number of cylinders to be deactivated, based on a reference range in which the pressure inside the intake manifold is included.
