LUBRICATION SYSTEM OF AN INTERNAL COMBUSTION ENGINE
First Claim
1. A lubrication system of an internal combustion engine comprising:
- an internal combustion engine through which lubricating oil circulates;
a generator that is capable of carrying out heat exchange with the lubricating oil in said internal combustion engine; and
control means that raises the temperature of the lubricating oil by means of heat produced by said generator and supplies the lubricating oil thus raised in temperature to said internal combustion engine, wherein said control means decreases an amount of the lubricating oil to be heat exchanged with said generator in a period of time in which the temperature of said generator becomes lower than the temperature of the lubricating oil.

Abstract
The present invention is intended to reduce the friction of an internal combustion engine in a suitable manner when the internal combustion engine is in a cold state, thereby to attain the reduction of fuel consumption as well as the reduction of exhaust emission. In order to achieve this object, a lubrication system of an internal combustion engine of the present invention is provided with a generator which is capable of carrying out heat exchange with lubricating oil in the internal combustion engine, wherein an amount of electric power generated by the generator is increased when the temperature of the lubricating oil is lower than a target temperature. According to this lubrication system of an internal combustion engine, it becomes possible to quickly raise the temperature of the lubricating oil to the target temperature with the heat produced by the generator.
