Abstract

Various embodiments of systems and methods related to controlling oil injection for piston cooling in an engine are disclosed. In one embodiment, a method includes during an engine cold start event, enabling oil injection onto a piston of an engine, disabling oil injection after the engine cold start event, and re-enabling oil injection after the engine cold start event based on a first operating parameter.

First claim

The invention claimed is:

1. A method comprising:
during an engine cold start event, enabling oil injection via at least one oil injector onto a piston of an engine;
disabling oil injection via the at least one oil injector after the engine cold start event; and
re-enabling oil injection via the at least one oil injector after the engine cold start event based on a first operating parameter.

2. The method of claim 1 , further comprising:
varying an oil…
