Diesel
Refined from crude oil, diesel fuel is what we call the distillate fuel
oil
used in some internal combustion engines.
In today’s global economy, diesel fuel is used in most heavy equipment
applications including tractor trailers, delivery trucks, construction
equipment, and buses. Diesel is also used in some pedestrian vehicles
such
as cars and light trucks.
"Diesel fuel, also called diesel oil, heavy oil (historically) or simply
diesel, is any liquid fuel specifically designed for use in a diesel
engine,
a type of internal combustion engine in which fuel ignition takes place
without a spark as a result of compression of the inlet air and then
injection of fuel. Therefore, diesel fuel needs good compression
ignition
characteristics.
In many countries, diesel fuel is standardized. For example, in the
European
Union, the standard for diesel fuel is EN 590. Ultra-low-sulfur diesel
(ULSD) is a diesel fuel with substantially lowered sulfur contents. As
of
2016, almost all of the petroleum-based diesel fuel available in the
United
Kingdom, mainland Europe, and North America is of a ULSD type. Before
diesel
fuel had been standardized, the majority of diesel engines typically ran
on
cheap fuel oils. These fuel oils are still used in watercraft diesel
engines. Despite being specifically designed for diesel engines, diesel
fuel
can also be used as fuel for several non-diesel engines .
