NOVELTY - An emission-reducing gasoline-diesel additive comprises 1-10 wt.% graphene/zinc oxide mixed powder, 10-20 wt.% bio-oil, 5-10 wt.% dispersant, 0.1-0.3 wt.% dicyclopentadienyl iron, 1-5 wt.% antirust agent, 0.1-0.5 wt.% demulsifier, and balance diluent. USE - Emission-reducing gasoline-diesel additive. ADVANTAGE - The additive eliminates carbon deposit inside the engine cylinder and piston, prolongs service life of the engine, reduces corrosion of the fuel oil supply pipeline, reduces exhaust emissions, anti-wear, and noise, ensures smooth fuel supply system, maintains fuel injectors, and solves problems of difficulty, slow acceleration, idling, and panting. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the additive comprising adding graphene/zinc oxide blended powder, dicyclopentadienyl iron, rust inhibitor, demulsifier, and dispersant into t mixed reaction kettle, mixing, stirring for 10-30 minutes, adding bio-oil, and diluent, and stirring for 1-2 hours.
