Water can get into diesel fuel as a result of condensation, rainwater penetration or adsorption from the air — modern biodiesel is especially hygroscopic. The presence of water then encourages microbial growth which either occurs at the interface between the oil and water or on the tank walls, depending on whether the microbes need oxygen .
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 ...
Diesel fuel has many colloquial names; most commonly, it is simply referred to as diesel.In the United Kingdom, diesel fuel for road use is commonly called diesel or sometimes white diesel if required to differentiate it from a reduced-tax agricultural-only product containing an identifying coloured dye known as red diesel.
Tier II regulations also defined restrictions for the amount of sulfur allowed in gasoline and diesel fuel, since sulfur can interfere with the operation of advanced exhaust treatment systems such as selective catalytic converters and diesel particulate filters. Sulfur content in gasoline was limited to an average of 120 parts-per-million ...
That includes thousands of used vehicles, so check out the emissions before you buy. Pro: Diesel is also very efficient; even the U.S. Department of Energy says some diesel engines can go 20% to ...
The US energy market is complex and there’s no single cause for higher diesel prices. Part of the explanation is a 4% reduction in diesel refining capacity that began in 2020, when oil prices ...
Fuel polishing is the technical cleaning process used to remove or filter microbial contamination from oil and hydrocarbon fuel in storage. It is essentially the removal of water, sediment and microbial contamination from such fuels as diesel , red diesel and biodiesel .
