what is the difference between diesel and bunker fuel?
527990
Essential Difference Between Diesel Fuel, Fuel Oil, and Bunker Fuel. With respect to chemical makeup, the difference between diesel, fuel oil, and bunker fuel is hydrocarbon size. Of the three, diesel contains the smallest, shortest hydrocarbon chains. Bunker fuel has the longest, largest hydrocarbon molecule chains.

While they are a considerably more expensive alternative in comparison to natural gas generators, since the price of diesel is more than that of gas, diesel has a higher energy density. ... Hence, fuel efficiency is by far the single most important advantage of diesel generators.

Dyed diesel and off-road diesel can be kerosene (which crosses as #1 diesel fuel), but not necessarily. Do not assume a dyed fuel is kerosene, which is a rarer fuel. Kerosene is different than #1 diesel for one characteristic: its confirmed ability to be absorbed and taken up by a wick. All kerosene is #1 diesel.

Gasoline is quite volatile and evaporates quickly. Gasoline ignites very easily with a match, too easily, but diesel is hard or impossible to light with a match. Gasoline has less viscosity than water, although this might be hard to determine by shaking a container. Diesel has a viscosity slightly greater than water.

A premium diesel has a higher cetane number, better lubricity and includes detergents that provide injector-cleaning capability versus standard #2 diesel. Cetane measures a fuel's ignition delay. Higher cetane equals a shorter delay and better ignition quality for quicker start-ups and less pollution.

In a gasoline engine, fuel is mixed with air, compressed by pistons and ignited by sparks from spark plugs. In a diesel engine, however, the air is compressed first, and then the fuel is injected.

Most of the compounds in diesel fuel are hydrocarbons of the paraffinic, naphthenic, or aromatic class. Diesel fuel also contains small quantities of organic compounds of sulfur (e.g., dibenzothiophene), nitrogen (e.g., carbazole), and oxygen.

​What's the difference between 91 and 95 octane fuel? Put simply, the only difference between these two fuels is their Research Octane Number, with the higher-octane 95 unleaded designed to be more fuel efficient and lead to a smoother engine operation.

Low diesel oil is comparatively cheaper and can be used for low speed engines, making it perfect for applications like ships, etc. ... The main difference is that high speed diesel is used as a fuel for high speed diesel engine operating above 750 rpm for example -buses ,lorries.

The main difference between their premium and regular fuel is the octane level they have. the premium ones have a higher octane level than the regular ones, this is the main difference they have. ... The shell V-power is just a fancy name shell gave to their premium fuels. They are just High octane super unleaded fuels.

You won't have to worry about which type to use because all diesel automakers specify Diesel #2 for normal driving conditions. Truckers use Diesel #2 to carry heavy loads for long distances at sustained speeds because it's less volatile than Diesel #1 and provides greater fuel economy.

All diesel sold in the United States typically has some dye in it. On-road diesel usually has a slight green tint to it. This is a dye added by either the refiner or terminal provider with the fuel. Off road diesels are dyed red to denote that the fuel is untaxed and is for use in off-road purposes only.

PRO: Diesels get great mileage. They typically deliver 25 to 30 percent better fuel economy than similarly performing gasoline engines. ... PRO: Diesel fuel is one of the most efficient and energy dense fuels available today. Because it contains more usable energy than gasoline, it delivers better fuel economy.

The fuel which we use in compression ignition engine or diesel engine is called as diesel. ... HSD is normally used in the engine which runs above 750rpm such as in buses, locomotives, trucks etc. And LDO is used in below 750 rpm engines. Generally it is used in steady engines or to burn in furnace.

Fuel costs: On average, diesel engines are rated about 25% more fuel efficient than similarly sized and power rated gasoline engines. Currently, diesel fuel is about 20% more expensive than gasoline, but prices are volatile and in some Canadian markets, diesel is actually slightly cheaper than gasoline.

For the most part diesel fuels are all coming from the same source and have the same additives so there is little difference between brands. However there are differences between individual stations. ... Brand names like “Shell” or “Chevron” are meaningless.

But the fact remains that diesels are more efficient than gasoline engines—and according to one recent study, newer models are cleaner, except for their higher emissions of nitrogen oxides. ... Because diesels are more efficient, they do in fact emit less carbon dioxide than gasoline engines.
