【 Diesel Oil 】

Diesel oil refers to the blending of distillate oil produced by crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum coking and other processes; it can also be produced by shale oil processing and coal liquefaction. It is a mixture of light petroleum products and complex hydrocarbons (carbon atom number is about 10-22). It includes light diesel (boiling point range is about 180-370 ℃) and heavy diesel (boiling point range is about 350-500 ℃).


Compared with gasoline, diesel oil has higher energy density and lower fuel consumption rate. Widely used in large vehicles, railway locomotives, ships and power generation.


Diesel fuel is a blend of different middle distillates derived from the crude oil refining process. It is usually composed of light and heavy gas oil, light and heavy cycle oil, as well as vacuum gas oil. The chemical components are alkenes, cyclo alkanes and different carbon hydrides. The boiling range is between 200°C and 500°C.


The international trading names are DMA (Diesel Oil, Marine Gas Oil /MGO) and DMB (Marine Diesel Oil /MDO). The main differences between these fuels are their viscosities, densities, as well as their sulphur content.


1. Diesel oil, Other designations is Gas oil and Marine Gas Oil (MGO). Diesel oil is a crude oil medium distillate and therefore must not contain any residual materials. The ISO 8217-2010 (Class DMA ) standards have been extensively used as the basis when defining these properties. The properties correspond to the test procedures stated. 


2. Marine diesel Oil (MDO), also known as Marine diesel fuel, Its is supplied as heavy distillate (designation ISO-F-DMB) exclusively for marine applications. MDO is manufactured from crude oil and must be free of organic acids and non-mineral oil products. The properties are essentially defined using the ISO 8217-2010 standard as the basis.


All of SOAR’s liquid fuel engines are capable of burning distillated fuels. Of course, our medium speed dual fuel engines  are capable of burning MFO blended with gas or if gas is not available, in 100% liquid fuel mode.
