First Claim
Patent Images
1. A lubrication system for an internal combustion engine, comprising:
- 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.

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.

14. An engine method, comprising:
-
during a first condition, pumping oil to piston cooling jets of the engine through a heat accumulator; during a second condition; pumping oil to the piston cooling jets through a radiator, bypassing the heat accumulator, and periodically recharging the heat accumulator by pumping engine oil through the heat accumulator; and in response to operating conditions, interrupting the recharge. - View Dependent Claims (15, 16, 17, 18, 19, 20)
