Abstract: Ashless energy-saving additives not only can save energy and eliminate soot but also cause no sec-ondary pollution to the atmosphere, and therefore,
they represent the trend of development of energy-saving additives for fuel oil. FA-1 universal ashless energy-saving additive has been developed in accor-dance with this trend. Investigation results indicate that the optimum amount of FA-1 added is about 0.1% (volume), the efficiency of saving of oil is 4.7 on bench test and the average efficiency of saving of oil is 15-20% ( no less than 10% for new motor vehicles ) on road test. FA-1 also has many other
functions, such as supporting combustion, eliminat-ing soot, reducing HC and CO2 emissions, lessening carbon deposit, reducing engine noise and enhancing mechanical horsepower, etc. After analyzing these test results, it is proposed that the mechanism of FA-1 lies in the improvement of the spray quality of fuel oil and the chain reaction of three molecules oc-curring between oxygen and FA-1.
