摘要: One example method includes varying oil injection by an oil injector onto a piston of an engine to accommodate different operating conditions. For example, by adjusting oil injection, suitable cooling effects can be provided without providing additional oil that increases the amount of oil deposits in the engine. In this way, the risk of pre-ignition can be reduced.

In one example, a method for controlling airflow into a cylinder of an engine comprises, if a previous cylinder airflow is different than a desired cylinder airflow, allocating flow into an intake manifold between a throttle and an EGR valve to provide the desired cylinder airflow while maintaining a desired EGR amount in the cylinder. In this way, transient air flow requests may be met without delay while maintaining desired cylinder EGR amounts.
