Abstract
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.
