Diesel fuel has a wide hydrocarbon spectrum with a carbon chain length of 12 to 20 carbon atoms. The large size of diesel fuel molecules as well as the high volume of the inlet fuel in heavy-duty diesel engines causes the combustion efficiency to decrease and a large amount of fuel to be burnt incomplete. It not only wastes energy but also emits soot (C) and toxic gases such as carbon monoxide (CO) and unburned hydrocarbons (HC) which pollute the environment. But with REDUCS installation, diesel fuel burns better and more energy is extracted. By more complete combustion of diesel fuel, the amount of soot, carbon monoxide and unburned hydrocarbons in the exhaust outlet is reduced which both reduces energy loss and reduces environmental pollutants such as soot, carbon monoxide and unburned hydrocarbons.
