dieselöljyyn

Dieselöljyyn, commonly known as diesel fuel, is a type of fuel derived from petroleum. It is primarily used in diesel engines, which are internal combustion engines that use compression ignition. Unlike gasoline engines that use spark plugs to ignite the fuel-air mixture, diesel engines rely on the heat generated by compressing air to ignite the injected fuel.

The production of diesel oil involves fractional distillation of crude oil. During this process, crude oil is heated and separated into various components based on their boiling points. Diesel fuel falls within a specific boiling point range, making it distinct from lighter fractions like gasoline and heavier fractions like lubricating oils.

Diesel fuel is characterized by its higher energy density compared to gasoline, meaning it can provide more power for a given volume. This, along with the inherent efficiency of diesel engines, makes it a popular choice for heavy-duty vehicles, trucks, buses, trains, and ships, where fuel economy and torque are crucial.

However, diesel combustion can produce particulate matter and nitrogen oxides (NOx), which are considered pollutants. Modern diesel engines and fuel formulations incorporate advanced technologies and additives to reduce these emissions, such as diesel particulate filters (DPFs) and selective catalytic reduction (SCR) systems. The composition and quality of diesel fuel can vary, with different standards and grades available depending on the region and application.
