摘要: An electronic valve actuation system and control method is described. The valve timing is changed between early and late intake valve closing depending on engine operating conditions. Further, valve timing is adjusted to control engine airflow or engine torque. Finally, air-fuel ratio is adjusted based on feedback from an exhaust gas oxygen sensor as well as an estimate of air, fuel, and residual exhausted from cylinders operating with late valve closing (after bottom dead center) timing.

摘要: A system for the just-in time scheduling of camshaft timing for an internal combustion engine. A slave circuit generates an execution period corresponding to the execution period of the variable camshaft timing mechanisms. The control processor initiates the calculation of a correction signal base on the difference between the desired camshaft timing and the actual camshaft timing synchronous with the execution period of the variable camshaft timing mechanism. The calculation of the correction signal is executed by the central processing unit once and only once for each execution period of the variable camshaft timing mechanism.
