The range of its hydrocarbons is 250 degrees Celsius. Gas oil mainly consists of three groups - with a boiling point range of 385 C and even 25 C-14 C between 20 54 and a maximum pour point of 0 �?�°C, paraffinic, naphthenic and aromatic, and has a minimum ignition point of -820. Its most important characteristic is 860 kg/m 15.6 equal to 3 �?�°C. Its density is at room temperature, which should be more than 50 for the engine to work smoothly and quietly. Cetane number is a measure to show the delay time of fuel combustion in engines. This number shows the delay time between the start of injection into the combustion chamber and the start of fuel combustion. During this time delay, the fuel accumulates and then ignites, and this combustion takes place in the form of an explosion in order to produce a power stroke. The shorter the delay time, the more uniform the ignition. The minimum cetane number for oil and gas should be 50. The amount of cetane number depends on the process from which oil and gas are produced. Oil and gas production have a high cetane number and their combustion quality is very good.
