Distillation range test methods and requirements required in the vehicle diesel standard GB19147

Distillation range test methods and requirements required in the vehicle diesel standard GB19147 The Vehicle Diesel (GB 19147-2016) stipulates the terms and definitions, product classification, technical requirements and test methods, sampling, marking, packaging, transportation and storage, safety and implementation
of standards for vehicle diesel.

This standard applies to automotive diesel
used in compression-engined vehicles, made from petroleum, or with additives to improve the use of performance.

This standard does not apply to vehicle diesel with biodiesel
as a blended component.

Diesel: The distillation range has two categories
: 180 ~ 370 °C and 350 ~ 410 °C.

According to the standard of vehicle diesel, the distillation range temperature is generally in the range of
300-365.

According to the requirements of GB19147 standard, the detection of the distillation range is required according to the GB/T6536 standard, and the automatic distillation range boiling range instrument SH6536 is designed and produced in strict accordance with the GB/T6536 standard, which can measure the boiling range
of the distillation range of petroleum refined oil vehicle diesel.

For petroleum and its processed products, it is customary to call those with a low boiling point or boiling point range light, and on the contrary called heavy
.

Therefore, the former is called light diesel, and the latter is called heavy diesel
.

Commercial diesel is classified according to the freezing point, such as 10, 0, -10, -20, etc.
, indicating the applicable ambient temperature, diesel is widely used in vehicles (including trains), ships and diesel boilers
using diesel internal combustion engines.

Since high-speed diesel engines (for automobiles) are more fuel efficient than gasoline engines, diesel demand is growing faster than gasoline, and some small cars are also switching to diesel
.
