dieselkütused

Dieselkütused, also known as diesel fuel, is a type of fuel oil commonly used in diesel engines. It is derived from petroleum and is characterized by its higher energy density compared to gasoline. The production of diesel fuel involves the fractional distillation of crude oil, where it is separated into various components based on their boiling points. Diesel fuel is typically composed of hydrocarbons, with a significant portion being heavier molecules than those found in gasoline.

The combustion process in a diesel engine differs from that of a gasoline engine. Diesel engines utilize compression ignition, where the fuel is injected into a cylinder filled with highly compressed, hot air. The heat generated by the compression ignites the fuel, leading to combustion. This method contributes to the higher efficiency of diesel engines, particularly under load.

Diesel fuel is widely used in transportation, powering trucks, buses, trains, and ships, as well as in agricultural machinery and industrial generators. Its properties, such as cetane number, which indicates ignition quality, and sulfur content, are important factors influencing its performance and environmental impact. Environmental regulations have led to the development of lower-sulfur diesel fuels and alternative diesel fuels like biodiesel, which is produced from vegetable oils or animal fats. The availability and price of diesel fuel are influenced by global oil markets and geopolitical factors.
