heating up diesel?
 

Are there any advantages to heating up diesel. and dose anyone know if you have to heat up WMO to run in a engine. :s:

The only reason to heat diesel is to prevent gelling in cold weather to aide in starting and running.

Thoughts and facts 'bout this:

Diesel expands if you heat it up.

Experimented with it already: 5 ml of diesel 20°C (68°F) room temperature and expanding to 7ml at 80°C(176°F) measured with a chem lab burette.

This the reason why the VW Phaeton has a fuel cooler behind the IP.
The Diesel is heated up by the extreme pressure of the IP.

Inside of most modern IP's you will also find a temperature sensor for fuel temperature compensation.
That means cold fuel is denser and contains as a result more BTU's by weight. If you heat the fuel you have to inject more fuel to get the same amount of BTU's.
So the engine injects more fuel with heated up fuel- this could lead to an increase of fuel consumption by approximately 30%
The only advantage might be a smoother engine run.

BUT: If you have an VP44 heat is poison for the IP. They are known for heat failure.

heat isnt too good for the PMD in the 6.5TD either
