diislikütu

Diislikütu is a term that refers to a specific type of liquid fuel, most commonly associated with diesel engines. It is a complex mixture of hydrocarbons derived from petroleum. The refining process of crude oil yields various fractions, and diislikütu is one such fraction, characterized by its distillation range and chemical properties. Its primary use is as fuel for diesel engines, which are a type of internal combustion engine that ignites fuel by the heat of compression rather than by a spark plug.

The composition of diislikütu can vary depending on the crude oil source and the refining process employed. Key properties include its cetane number, which indicates the fuel's ignition quality, and its viscosity, which affects its flow characteristics and lubricating properties. Sulfur content is another important factor, as regulations often limit the amount of sulfur allowed in diesel fuel for environmental reasons. Modern diislikütu formulations may also include additives to improve performance, stability, and reduce emissions. These additives can enhance lubrication, prevent corrosion, and improve cold-weather operability.

The production and use of diislikütu are significant aspects of the global energy economy. It powers a wide range of vehicles, including trucks, buses, trains, and some passenger cars, as well as agricultural machinery and industrial generators. Environmental concerns related to the combustion of diislikütu, particularly the emission of particulate matter and nitrogen oxides, have led to the development of lower-sulfur fuels and advanced engine technologies.
