What is the calorific value of a diesel?
roughly 45.5 MJ/kg
The calorific value of diesel fuel is roughly 45.5 MJ/kg (megajoules per kilogram), slightly lower than petrol which is 45.8 MJ/kg. However, diesel fuel is denser than petrol and contains about 15% more energy by volume (roughly 36.9 MJ/litre compared to 33.7 MJ/litre).
What is the difference between HSD and LDO?
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.
What is diesel Max?
DIESEL MAX is a premium quality fuel that contains a multifunctional additive system to provide unsurpassed detergency characteristics for a cleaner engine and better smoke control, more efficient combustion for maximum acceleration and smooth power, and an improved burning quality and a fuel economy.

Which fuel has high calorific value?
hydrogen
Calorific value is nothing but the energy contained in a fuel or food, determined by measuring the heat produced by the complete combustion of a specified quantity of it. This is now usually expressed in joules per kilogram. Hence, hydrogen has the highest calorific value.
Is high flow diesel the same as normal diesel?
High flow or not, comes from the same tank. Big truck stops may have more than one tank, but it’ll still be the same fuel in both with an auto switchover. In some cases they may have their premium diesel going only to the low flow pump and the lower spec diesel to the highflows.
What is a low speed diesel engine?
In ship: Diesel. The low-speed engine is characterized by rated speeds in the range of 80–120 revolutions per minute. In all cases it is a two-stroke engine supercharged by exhaust-gas turbochargers.
Which diesel fuel is best quality?
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.
Are there grades of diesel?
Standard diesel fuel (sometimes called diesel oil) comes in two grades: Diesel #1 (or 1-D) and Diesel #2 (or 2-D). Just as gasoline is rated by its octane, diesel fuel is rated by its cetane, which indicates how easy it is to ignite and how fast it burns. Most diesel vehicles use fuel with a rating of 40 to 55.
What is the difference between LDO and diesel?
Two main grades of diesel fuel are marketed in India, High Speed Diesel (HSD) and Light diesel oil (LDO). The former is a 100% distillate fuel while the latter is a blend of distillate fuel with a small proportion of residual fuel.
What is high speed diesel oil?
Diesel Oil is a complex mixture of Hydro Carbons. It is a brown coloured oily liquid with pungent smell. HSD is normally used as a fuel in medium and high speed compression ignition engines (operating above 750 rpm) in commercial vehicles, stationary diesel engines, locomotives and pumps etc.
What is the calorific value of diesel or HSD?
Calorific value decides the efficiency of an energy source per unit weight. The Typical Gross calorific value of Diesel or HSD is 10800 Kcal/kg. Disclaimer: Views and opinions expressed here are personal.
What kind of fuel is used for slow speed diesel?
It is marketed under BIS 15770-2008 specification. LDO is used for slow speed diesel engines (below 750 rpm). It is also used in Lift irrigation pumpsets, DG Sets and as a fuel in certain boilers and furnaces where low sulfur fuel is required.
What makes a fuel have a lower calorific value?
Lower Calorific Value (= Net Calorific Value – NCV = Lower Heating Value – LHV) – the products of combustion contains the water vapor and the heat in the water vapor is not recovered The table below gives the gross and net heating value of fossil fuels as well as some alternative biobased fuels.
What is the chemical name of high speed diesel?
