| High Speed Diesel |
| |
Petroleum derived diesel (called as petrodiesel) is a mixture of straight run product (150 °C and 350 °C) with varying amount of selected cracked distillates and is composed of saturated hydrocarbons (primarily paraffins including n , iso , and cycloparaffins), and aromatic hydrocarbons (including napthalenes and alkylbenzenes).

Diesel is used in diesel engines, a type of internal combustion engine. Rudolf Diesel originally designed the diesel engine to use coal dust as a fuel, but oil proved more effective. Diesel engines are used in cars, motorcycles, boats and locomotives. Automotive diesel fuel serves to power trains, buses, trucks, and automobiles, to run construction, petroleum drilling and other off-road equipment and to be the prime mover in a wide range of power generation & pumping applications. The diesel engine is high compression, self-ignition engine. Fuel is ignited by the heat of high compression and no spark plug is used.
|
The Indian Standard governing the properties of diesel fuels is IS 1460:2005 (5th Rev). Important characteristics are ignition characteristics, handling at low temperature, flash point.
|
Diesel fuel often contains higher quantities of sulphur. In India , emission standards (equivalent to Euro II, Euro III, Euro IV) have necessitated oil refineries to dramatically reduce the level of sulphur in diesel in view of the auto fuel policy brought in force by Govt of India.

BIS has brought out specification for "Diesel with 5% Biodiesel" that may be marketed in near future.
