First Claim
Patent Images
1. An engine method, comprising:
- during a first condition, pumping oil to piston cooling jets of an engine through a chemical heat accumulator;
during a second condition;
pumping oil to the piston cooling jets through a radiator, bypassing the heat accumulator, andperiodically recharging the heat accumulator by pumping engine oil through the heat accumulator; and
in response to engine knocking, interrupting the recharge.

Abstract
Embodiments for a lubrication system for an internal combustion engine are provided. In one example, a lubrication system for an internal combustion engine comprises a lubricant circuit, a radiator for cooling the lubricant, a heat accumulator arranged upstream of the engine for warming up the lubricant, the heat accumulator connected in parallel to the radiator, and a valve for switching over the lubricant circuit between the radiator and the heat accumulator. In this way, the oil may be rapidly heated during cold engine start conditions.
