What is Battery and why it is used?
Battery is the primary power source for any electronics wireless gadget, be it a smartphone, laptop, watch or remote. Can you imagine the situation without these energy sources? We wouldn’t be…
Diesel Fuel Cetane
Cetane is a colorless, liquid hydrocarbon (a molecule from the alkane series) that ignites easily under compression. For this reason, it was given a base rating of 100 and is used…
Rating of CI Engine Fuels
In compression-ignition engines, the knock resistance depends on chemical characteristics as well as as on the operating and design conditions of the CI engine. Therefore, the knock rating of a…
What is octane rating?
Octane rating is the measure of a fuel's ability to resist "knocking" or "pinging" during combustion, caused by the air/fuel mixture detonating prematurely in the engine. In the U.S., unleaded…
SI ENGINE
Spark-ignition engines normally use volatile liquid fuels. Preparation of fuel-air mixture is done outside the engine cylinder and formation of a homogeneous mixture is normally not completed in the inlet…
Copper Strip Corrosion
This is a qualitative method that is used to determine the level of corrosion of petroleum products. In this test, a polished copper strip is suspended in the product and…
Aniline point
The aniline point of an oil is defined as the minimum temperature at which equal volumes of aniline (C6H5NH2) and lubricant oil are miscible, i.e. form a single phase upon mixing.. The value gives an…
What is API Gravity?
Industry indicator API gravity is short for American Petroleum Institute gravity, an inverse measure that is used to determine the weight of petroleum liquids in comparison to water. If a liquid has API…
Fuel viscosity control
Fuel viscosity control is a technique to control viscosity and temperature of fuel oil (FO) for efficient combustion in diesel engines of motor vessels and generators of oil-fired power plants. Fuel oil's viscosity strongly depends on the temperature, the higher is…
Vapor pressure
Vapor pressure is an important quality specification for gasoline. Specifically, vapor pressure is a measure of the volatility of a fuel, or the degree to which it vaporizes at a given…
