What is #2 diesel fuel?
#2 is the kind of diesel you’re most likely to find at gas stations across the country and around the world. This type of diesel fuel has the highest number of energy components and lubricating properties you’ll find in a fuel mixture, and offers the best overall fuel performance on the market.
What is the specific gravity of #2 diesel fuel?
2 diesel fuel is between 30 and 42. The specific gravity, at 60/60°F, and the density, at 15.6°C, are between 0.88 and 0.82.
What is the difference between #1 diesel and #2 diesel?
Diesel #1 is also known as winter diesel because it performs better than Diesel #2 in cold temperatures. It has a lower viscosity and is not prone to gel in freezing temperatures. Most stations offer a premium Diesel mix that is blended for local weather conditions. Diesel #2 costs less at the pump.
How do you know if diesel is good?
You can conduct a simple test for verifying the quality of diesel filled in your vehicle. To go ahead with this inspection, you would require a 500-millilitre glass jar, a thermometer, a hydrometer, and an ASTM (American Society for Testing of Materials) conversion chart.
How cold is #2 diesel good for?
approximately 14 degrees F.
2 diesel is approximately 14 degrees F. A good rule of thumb is to switch to a winter blend 15 degrees above cloud point. When overnight temperatures begin to dip down near 30 degrees F, it’s time to blend in No. 1 diesel with additives for winter.
Will 1 gallon of gas hurt a diesel?
As little as 1% gasoline contamination will lower the diesel flash point by 18 degrees C. This means the diesel fuel will prematurely ignite in the diesel engine, which can lead to engine damage. Diesel has enough lubricity to lubricate the fuel pumps and the injectors.
What is the molecular weight of distillate fuel oil 2?
The US EPA lists “Distillate fuel oil #2” as having a liquid molecular weight of 188 and a vapor molecular weight of 130.
What is the molecular weight of gasoline and kerosene?
Gasoline molecular weight range is 60-150 g/mol. Non-limited Diesel fuel molecular weight range is 150-250 g/mol. Kerosene is a mixture of hydrocarbons. It is mixture of 10 to 16 carbon atoms in branched and straight chain.
Which is second in volume gasoline or diesel?
Diesel fuel is usually second in volume next to gasoline. Diesel blend consists of cuts from atmospheric distillation, hydrocracking, FCC light cycle oil, and some products obtained from visbreaking and coking. The main property of diesel fuel for automotive engine combustion is cetane number, which is a measure of engine start-up and combustion.
What kind of hydrocarbons are in diesel fuel?
Diesel fuels predominantly contain a mixture of C 10 through C 19 hydrocarbons, which include approximately 64% aliphatic hydrocarbons, l-2% olefinic hydrocarbons, and 35% aromatic hydrocarbons (Air Force 1989). Jet fuels are based primarily on straight-run kerosene, as well as additives.
