In North America, gas stations offer two types of diesel fuel – according to ASTM D975 [5] these are named No. 1 and No. 2 fuel. No. 1 fuel (similar to kerosene) has a natural CFPP of -40 °C but it is more expensive than No. 2 fuel. Adding No. 1 fuel will lower the CFPP of No. 2 fuel – adding 10% will lower the CFPP temperature by about 5 ...
The test is important in relation to the use of additives that allow spreading the usage of winter diesel at temperatures below the cloud point. The tests according to EN 590 show that a CloudPoint of +1 °C can have a CFPP −10 °C. Current additives allow a CFPP of −20 °C to be based on diesel fuel with a CloudPoint of −7 °C.
The D5773 test method determines the cloud point in a shorter period of time than manual method D2500. Less operator time is required to run the test using this automatic method. Additionally, no external chiller bath or refrigeration unit is needed. D5773 is capable of determining cloud point within a temperature range of -60 °C to +49 °C.
The standard EN 590 puts diesel fuel into two groups destined for specific climatic environments. ... Cloud point -10 -16 -22 -28 -34 °C Density at 15 °C 800 - 845 ...
The cloud point (or gel point) can be adjusted down to −40 °C (−40 °F) [10] during the manufacturing process, compared to petrodiesel's cloud point of −30 °C (−22 °F), [failed verification] which could improve the cloud point of diesel when blended. The cloud point is the temperature when the wax precipitates out of the fuel in the ...
Number 1 fuel oil is a volatile distillate oil intended for vaporizing pot-type burners and high-performance/clean diesel engines. [8] It is the kerosene refinery cut that boils off immediately after the heavy naphtha cut used for gasoline. This fuel is commonly known as diesel no. 1, kerosene, and jet fuel. Former names include: coal oil ...
In Europe, diesel cetane numbers were set at a minimum of 38 in 1994 and 40 in 2000. The standard for diesel sold in European Union, Iceland, Norway and Switzerland is defined by standard EN 590. Since 1 January 2001 EN 590 demands a minimum cetane index of 46 and a minimum cetane number of 51. Premium diesel fuel can have a cetane number as ...
Renewable diesel from vegetable oil is a growing substitute for petroleum. [14] California fleets used over 200 million US gallons (760,000 m 3 ) of renewable diesel in 2017. The California Air Resources Board predicts that over 2 billion US gallons (7,600,000 m 3 ) of fuel will be consumed in the state under its Low Carbon Fuel Standard ...
