Of the discharge line at the supply
Now remember scheme fuelling diesel. The composition of the discharge system, virtually all diesel engines includes two fuel - the supply and fuel discharge. On the supply toplivoprovodu fed fuel to the engine of toplivoprovodu plum - the reverse flow from the tank to the engine.
Naturally, when the engine on the discharge pipeline in the fuel tank comes at a temperature much higher temperature fuel in the tank. Used fuel in the tank, it has a few of his heats.
In most of the fuel tanks and suction machines, fuel and discharge tubes are located in close proximity of each other. However, it is that they are far removed, and in this case as closely as possible to discharge tube toplivopriemniku that in Basair fuel temperature was higher than the temperature in the rest of the tank volume.
It happens that this will be enough to finalize the smooth operation of the diesel engine at low temperatures.
