NOVELTY - Diesel concentrated fuel-saving net composition comprises 260-440 pts. wt. solvent, 120-180 pts. wt. biphenyl, 8-10 pts. wt. polyetheramine HF-B100, 250-300 pts. wt. peroxide ether, 5-10 pts. wt. cetane number enhancer, 80-150 pts. wt. lubricant, 60-100 pts. wt. fuel detergent, 5-10 pts. wt. fuel compounding agent, 5-10 pts. wt. fuel synergist. USE - Diesel concentrated fuel-saving net composition. ADVANTAGE - The diesel concentrated fuel-saving net composition is safe, environmentally friendly, and convenient to realize industrialized production, has simple preparation method, improves the quality of diesel oil, engine power performance, reduces fuel consumption, and pollutant emissions in engine exhaust, generation of sludge. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing diesel concentrated fuel-saving net composition, which involves adding solvent, biphenyl, polyetheramine HF-B100, peroxide ether, cetane number improver, lubricant, fuel detergent, fuel compounding agent, and fuel synergist to the oil mixing tank one by one, using gear pump to circulate and mixing twice through static mixer, and then filtering with 400-mesh filter, and then settling for 24-30 hours to obtain diesel concentrated fuel-saving net composition.
