    Abstract: A method for controlling a vehicle engine having a plurality of cylinders is provided. The method comprises: during engine idling, advancing spark timing of at least one cylinder to before a peak torque timing, and retarding spark timing from the advanced timing toward the peak torque timing in response to decreased engine speed to maintain idling speed.

    Abstract: A method for detection of emissions levels during extended engine speed controlled operation is provided. The method includes monitoring mass airflow passing through the engine while operating the engine. The method further includes adjusting mass airflow responsive to engine speed to maintain a desired engine speed. The method further includes shutting down the engine when engine mass airflow becomes higher than a predetermined mass airflow threshold.

    Abstract: A method for controlling stopping and starting of an engine having a variable event valvetrain is described. According to the method engine valves may be used to reduce engine evaporative emissions as well as engine starting emissions. Since the engine configuration shown has electrically actuated intake and exhaust valves it is possible to reconfigure the engine operating sequence during a start. For example, the pistons for cylinders two and three are in the same position at the same time. This allows either cylinder to be set to an intake stroke during a subsequent engine restart when the piston is traveling away from the cylinder head while the companion cylinder is set to the expansion or power stroke. Thus, the cylinder having the first intake stroke could be configured to provide a first combustion event during an engine restart. On the other hand, the cylinder set to the power stroke could have been set to the intake stroke such that it is the first cylinder to provide a combustion stroke during a restart.

    Abstract: A system and method for operating at least an intake and exhaust valve in a cylinder with a piston of an engine in a vehicle are described. In one aspect, the method comprises maintaining at least one of the intake and exhaust valves in a closed position during a period. Further, during said period where said at least one valve is in said closed position, the method may also include opening the other of the intake and exhaust valve, then closing the other of the intake and exhaust valve, and then opening the other of the intake and exhaust valve.
