ENGINE CONTROL SYSTEM [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)]


id0140h1139900


Outline

•  Engine coolant is supplied to the appropriate engine coolant passage according to the engine load conditions.
•  Further engine warming has been promoted by blocking each water passage while the engine is cool.
―  Coolant control valve adopted
•  Pumping loss due to intake/exhaust stroke is reduced to improve fuel economy during low engine loads.
―  Cylinder deactivation control adopted
