Modifying the Cloud Point
One method that can be used to lower the cloud point of a diesel fuel is to mix the diesel fuel with different fuel that has a lower cloud point, such as No. 1 diesel fuel or kerosene. The efficiency of this method is not good, because the ratio of the mixture does not have a direct relation to the improvement in cloud point. The percent of low cloud point fuel that must be used increases more than the cloud point is lowered.The following illustration contains a table that can be used to find the necessary mixture for two fuels with different cloud points. In order to use the table, you must know the exact cloud point specification of each fuel to be mixed. This specification can change from one purchase of fuel to the next purchase of fuel. This specification is normally available from personnel at the source of the fuel supply. This method cannot be used to prevent cloud point problems, when lower cloud point fuels are not available.The fuel manufacturer can also add flow improvers (wax crystal modifiers) to the fuel. Flow improvers do not change the cloud point of the fuel. However, flow improvers do keep the wax crystals small enough to pass through standard fuel filters. See the topic "Pour Point" for the mixing precautions.
Cloud point of fuel mixtures.Generally, the most practical method that is used to prevent problems that are caused by fuel cloud point at low temperatures is the use of fuel heaters. In most applications, fuel heaters can be used at a lower cost than fuel mixtures.Pour Point
The pour point of a fuel is a temperature, that is below the cloud point, at which the fuel will no longer flow. The pour point is the temperature which limits the movement of the fuel with pumps.To measure the pour point, the fuel temperature is lowered below the cloud point in steps of 3°C (5°F) at a time. The fuel temperature is lowered until the fuel will no longer flow. The pour point is the last temperature that is shown before the flow stops. At the pour point temperature, the amount of wax particles has increased to a point at which the particles connect together. This makes the fuel more solid than liquid. The pour point of the fuel can be improved without removal of important elements as in cloud point improvement.A fuel's pour point should be at least 6°C (10°F) below the lowest ambient temperature that is required for engine start-up and for engine operation. To operate the engine in extremely cold weather, No. 1 fuel of No. 1-D fuel may be necessary because of the fuels' lower pour points.Modifying the Pour Point
The pour point of a fuel can be lowered either by the use of additives or by a mixture with a lower pour point fuel as given in the paragraphs for "Cloud Point". As with the cloud point, use of a mixture does not give good
