diiselkütuseks

Diiselkütus is the Estonian term for diesel fuel. It is a type of fuel derived from petroleum and is primarily used in diesel engines, which are characterized by their compression-ignition system. Unlike gasoline engines that use spark plugs to ignite the fuel-air mixture, diesel engines compress the air to a high temperature, and then the fuel is injected, causing it to ignite spontaneously. This process makes diesel engines generally more fuel-efficient and capable of producing higher torque compared to gasoline engines.

The production of diesel fuel involves the fractional distillation of crude oil. It is a complex hydrocarbon mixture with a higher boiling point range than gasoline. Historically, diesel fuel has been a popular choice for heavy-duty vehicles, trucks, buses, trains, and ships due to its power and efficiency. It is also used in some passenger cars, generators, and agricultural machinery.

While diiselkütus offers advantages in terms of energy density and engine longevity, its combustion process can also produce certain emissions, including nitrogen oxides (NOx) and particulate matter. Environmental regulations have led to the development of cleaner diesel formulations and more advanced exhaust treatment systems to mitigate these emissions. The availability and price of diiselkütus are influenced by global oil markets and geopolitical factors.
