Piston squirter system for internal combustion engine e.g. compression-ignited internal combustion engine, has variable displacement pump that provides oil to passage, and piston squirter to spray oil towards piston

摘要

The system has variable displacement pump (52) that provides oil to the passage (58). A piston squirter (54) is connected with the passage to spray oil towards piston (50) provided in the cylinder (48). An independent claim is included for method of pumping oil to piston squirter in internal combustion engine.
