NOVELTY - The utility model claims a negative ion graphene oil-saving device, comprising an upper hard plastic plate and a lower hard plastic plate; between the upper hard plastic plate and the lower hard plastic plate is provided with a first anion graphene layer; tourmaline powder layer and the second anion graphene layer; the tourmaline powder layer is set between the first anion graphene layer and the second anion graphene layer; two ends of one of the hard plastic respectively is embedded with magnetic iron sheet with opposite polarity. The negative ion graphene oil saving device of the utility model has infrared radiation and negative ion releasing function, which can make the gas, oil molecular group become small, increase the oxygen activity, improve the combustion efficiency, reduce black smoke waste gas, generally energy-saving effect reaches 20 % or more.
