diislikütustega

Diislikütustega refers to fuels designed for use in diesel engines. These fuels are derived primarily from crude oil through a process called distillation, which separates components based on their boiling points. Diesel fuel is characterized by its higher flash point and autoignition temperature compared to gasoline, making it suitable for compression-ignition engines.

The composition of diesel fuel can vary, but it generally consists of hydrocarbons with carbon chains typically ranging from C12 to C20. Key properties that define diesel fuel quality include cetane number, which indicates its combustion quality and ease of ignition, and viscosity, which affects fuel flow and atomization. Sulfur content has also been a significant factor, with regulations increasingly mandating low-sulfur diesel to reduce harmful emissions.

Diesel engines are known for their fuel efficiency and torque, making diesel fuel a popular choice for heavy-duty vehicles, trucks, buses, and agricultural machinery. It is also used in some passenger cars, generators, and heating systems. The refining process and additive packages play a crucial role in tailoring diesel fuel for specific applications and meeting environmental standards. Alternative diesel fuels, such as biodiesel, are also gaining traction as sustainable options.
