LIGHT DIESEL OIL (LDO) – Call Us – 7347513707
LDO from indigenous sources offered in the e-market platform. The product application is mainly as fuel oil.
Light diesel oil, or LDO, is a blend of components from the distillation process of crude. It is used in engines with an rpm less than 750, such as boilers and furnaces. LDO is also referred to as distillate fuel or marked oil.
Light diesel oil is used as fuels in many applications :
Lower RPM engines
Lift irrigation pump sets
Furnace Oil (F.O), Light Diesel Oil (LDO), Superior Kerosene Oil (SKO) – Industrial , Low Sulphur Heavy Stock(LSHS) and Petcoke.
Introduction to Diesel
Fuels or Industrial Fuels (HSD and LDO)
Diesel fuel is basically a liquid fuel, also known as diesel oil which is used in diesel engines. Petroleum diesel is one of the type of diesel fuel which is also known as fossil diesel. It is generally find to be produced from the fractional distillation of crude oil. The average compression ratio of a diesel engine is much higher (about 15:1) than that of a gasoline engine (about 8:1) and this is the reason for the higher thermal efficiency of the diesel engine (about 33% as compared to about 25% of the gasoline engine) which makes for economy in operation. We are providing the best Industrial Fuel Oil (Industrial Fuel Oil Supplier in India)all over the country and that makes us the Best Industrial Fuel Oil Supplier in India. The important mechanical properties of diesel fuel includes the following:
Number generally defines the ignition qulity of a diesel fuel. Whenever the
cetane number is higher the ignition quality will also be higher. Cetane number
requirements depend on the size of the engine, its design, load and atmospheric
conditions. The minimum cetane number for diesel engines is recommended as 40.
Viscosity means the thickness of the fluid. It is simply a
measure of resistance to flow and it always decreases as the temperature
increases. Viscosity measures at 40 degree celsius in units mm2/s
The black coloured material is collected after burning the
diesel fuel is considered as carbon residue. The amount of carbon residue
depends upon the running conditions of the engine. The maximum mass of carbon
residue is 0.1%
the rule, when the viscosity of liquid fuel is higher it will lower its
volatility. Therefore provided the viscosity lies within specified limits, a
satisfactory volatility is automatically ensured. However, the percentage
recovered at some particular temperature e.g. 366 degree Celsius, is specified
in the case of HSD mainly to control engine fouling due to incomplete
combustion of the higher boiling components.
completion of combustion, sulphur from diesel fuel creates sulphuric acid which
causes corrosive wear on the metal surface of engine. Corrosion can be formed
within the engine after the formation of all acids but risk of corrosion
formation depends upon their acidity. Also, risk of corrosion can be increased
with the amount of acids and strength of acids in the mixture.
be low during storage and distribution in order to minimize the corrosion of
metals in contact with the fuel. Further, there are two types of acidity one is
organic acidity and another is inorganic or mineral acidity.
lowest temperature at which a petroleum substance will vapourises in the air
near its surface that will be known as the flash point. Flash point is used to
help in characterising the fire hazards so that it can be handled safely. The
minimum recommendation of flash point is 40 degree celsius.
content is the inorganic residue which is left behind after combustion of oil.
The range of ash content is 0.1% to 0.2%. Ash forming material such as
suspended solids and soluble organometallic compounds are present in diesel
Water and Sediment Content
amount of water in diesel fuel can be measured by ASTM D1744 and the amount of
sediment in diesel fuel can be measured by ASTM D2709. If there is a large
quantity of sediment then it may affect the combustion of fuel.
lowest temperature at which a petroleum substance will flow when tested under specific
conditions will be known as the pour point. It can be measured by ASTM D97.
temperature at which a petroleum substance shows the clouds of wax crystals
when it gets cooled under specific test conditions will be considered as the
cloud point. It can be measured by ASTM D2500.
Cold Filter Plugging Point
filter plugging point (CFPP) is defined as the lowest temperature which
measures the formation of wax crystals at low temperature. It is somewhat
similar to the concept of cloud point. CFPP and Cloud Point can be determine
according to the weather conditions and seasons of each country.
also known as the relative density. Basically, it refers to the ratio of
density of an object like oil or fuel with reference to the material like water
with a hydrometer at a given temperature. Variations in specific gravity affect
the volumetric fuel consumption of an engine, since the higher the specific
gravity the higher the heat content in a unit volume of the fuel. It usually
affects the spray pattern of fuel while injected into the cylinder.
two main grades of diesel fuels are marketed in India, the one is High Speed
Diesel (HSD) and the another one is Light Diesel Oil (LDO). We are the best LDO suppliers in India providing the
best quality oil as compared to the others. We have described all the
properties of diesel fuel and have not hide anything from our customers.
