LUBRICATING OIL OF_AN INTERNAL COMBUSTION ENGINE
-FIELD AND BACKGROUND OF THE INVENTION
This invention relates in general to accessory devices or .automotive engines and in particular to a new and useul heater arrangement -for selectively heating a liquid uel or the lubricating oil.
During the cold season, there is a risk that the fuel, particularly diesel oil, to be supplied to an internal combustion engine of a motor vehicle parked outdoors 5 for example, will not be supplied properly or not at all.
The same may happen with the lubricating oil to be supplied t~ the engine, whose lubricating capacity is largel~ reduced under low temperat~;res. To overcome this drawback, a va-r e~y 1~ o~ heaters for the fuel or the lubricating oil has alread~-been provided employing the waste heat of the eng;ne, namely heat exchangers operated with the waste heat or the coolant~
or independent electrical heaters.

and in which the line to the engine terminates with an ofifice 3a. In this line, closely upstream of a filter 5 provided at the engine, a line 4 is branched off leading to a heat exchanger 9 which, in the shown embodiment, is operated with the coolant of the engine in a manner which may not be explained in detail.
From this heat exchanger, a return line 7 extends which is connected, adjacent the engine, to a discharge line 4 leading to the fuel tank where it terminates in an orifice 4a. In branch line 6, an electrically operated circulating pump ~ is provided, and a check valve 10 is mounted in the return line 7 preventing the oil from flowing toward the heat exchanger.
If applied to lubricating oil heating, the invention provides an outgoing line 3' having an orifice 3a' and leading from the oil pan 2' of engine 1, which is connected, adjacent a filter (not shown), to a branch line to heat exchanger 9. From heat exchanger 9, the return line 7 opens into a line which leads to oil pan 2' where it terminates in an orifice 4a'.
Orifices 3a, 4a, and 3a', 4a', are located close to each other within fuel tank 2 and oil pan 2', respec-tively. The oil in the oil pan 2' is advantageously circulated from line 3' through a line having a valve 26 and returned through a line to return orifice 4a' when the valve 24 is opened. Similar valves may be located in the feed lines 3 and 4 to isolate the fuel heating from the oil heating or complete separate heating circuits are provided for each of the fuel and oil.
