摘要： A method of controlling a variable valve actuation system for an internal combustion engine having a plurality of cylinders, each of the plurality of cylinders having a variable valve actuator and in-cylinder pressure sensor is provided. Output of an in-cylinder pressure sensor is monitored at a predetermined crank angle Θp with an electronic control module. The output of the in-cylinder pressure sensor of the monitored one of the plurality of cylinders at the predetermined crank angle Θp is compared to a stored threshold value for in-cylinder pressure at the predetermined crank angle. A variable valve actuator is adjusted to adjust a crank angle Θc corresponding to when an intake valve of the monitored one of the plurality of cylinders closes when the output of the in-cylinder pressure sensor of the monitored one of the plurality of cylinders does not correspond to the stored threshold value.
