Heavy fuel oil. Heavy fuel oil (HFO) is a category of fuel oils of a tar -like consistency. Also known as bunker fuel, or residual fuel oil, HFO is the result or remnant from the distillation and cracking process of petroleum. For this reason, HFO is contaminated with several different compounds including aromatics, sulfur, and nitrogen, making ...
This fuel is sometimes known by the Navy specification of Bunker B. Number 6 fuel oil is a high-viscosity residual oil requiring preheating to 104–127 °C (219–261 °F). Residual means the material remaining after the more valuable cuts of crude oil have boiled off.
For fuel coke derived from coal, see Coke (fuel). Petroleum coke, abbreviated coke, pet coke or petcoke, is a final carbon -rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes. Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical ...
Mazut-100 is a fuel oil that is manufactured to GOST specifications, for example, GOST 10585-75 (not active) or GOST 10585-2013 (active as per December 2019 [ 5] ).

The Convair B-58 Hustler, designed and produced by American aircraft manufacturer Convair, was the first operational bomber capable of Mach 2 flight. [ 1] The B-58 was developed during the 1950s for the United States Air Force (USAF) Strategic Air Command (SAC). To achieve the high speeds desired, Convair chose a delta wing design used by ...
RP-1 (alternatively, Rocket Propellant-1 or Refined Petroleum-1) is a highly refined form of kerosene outwardly similar to jet fuel, used as rocket fuel. RP-1 provides a lower specific impulse than liquid hydrogen (H 2 ), but is cheaper, is stable at room temperature, and presents a lower explosion hazard. RP-1 is far denser than H 2, giving it ...
A bunker quantity survey ( BQS ), also known as a bunker quantity audit or simply a bunker survey, is a quantitative examination and assessment of fuel oil ( bunker fuel) transferred from one party to another. In the maritime industry, a BQS is conducted when a supply vessel (typically a bunker barge or shore tank) delivers fuel oil to a ...
And yes, there's quite a difference between models: With a 2015 Silverado you need to fill up 25 miles after the light comes on, but some cars like the Nissan Altima have three gallons left in the ...
