Abstract: Methods and systems are described for combustion engine mode optimization. The system includes a combustion engine, a fuel delivery system, and a controller communicatively coupled to the combustion engine and the fuel delivery system. The controller selects a low temperature combustion mode based on the combustion engine being warmer than a predetermined temperature and low load conditions on the combustion engine. The low temperature combustion mode includes instructions that reduces an intake valve opening duration and an exhaust valve opening duration. The controller reduces the intake valve opening duration and the exhaust valve opening duration to create a delay between an intake valve opening duration and an exhaust valve opening duration in response to selecting the low temperature combustion mode. The delay increases a residual gas temperature in the combustion chamber and induces auto-ignition of fuel in the combustion chamber.

Abstract: The present disclosure provides a system and a method for controlling valve timing of a continuous variable valve duration engine. The method may include: classifying a plurality of control regions depending on an engine speed and an engine load; applying a maximum duration to an intake valve in a first control region; maintaining the maximum duration of the intake valve and controlling a valve overlap by using exhaust valve closing (EVC) timing in a second control region; advancing intake valve closing (IVC) timing in a third control region; controlling the IVC timing to be close to bottom dead center (BDC) in a fourth control region; controlling a throttle valve to be fully opened and generating a scavenging phenomenon in a fifth control region; and controlling the throttle valve to be fully opened and controlling the IVC timing to prevent knocking in a sixth control region.

Abstract: A method for controlling valve timing of an engine may include: classifying control regions; applying a maximum duration to an intake valve and controlling a valve overlap in a first control region; applying the maximum duration to the intake valve and an exhaust valve in a second control region; controlling a manifold absolute pressure (MAP) of an intake manifold to be maintained constant in a third control region; controlling a wide open throttle valve (WOT) and creating a valve overlap by reducing interference of exhaust in a fourth control region; and controlling a wide open throttle valve (WOT) and controlling an intake valve closing timing based on the engine speed. In particular, the control regions are classified by a controller based on an engine load and an engine speed compared with predetermined values, respectively.
