Abstract: A fuel pipe that is made from nano or sub-nano plastic or rubber materials and can be used for motor vehicles and ships includes a nano or sub-nano Far Infrared Ray (FIR) and anion carrier. The structures of the carrier are made up of nano or sub-nano tourmaline granules integrated into the carrier body made from general, nano, or sub-nano plastic, rubber, resin, or metal materials. The carrier can be the whole body, interior or exterior wall, or paste structures set on the inner or outer wall surface of the pipe. The carrier can reach a far infrared emission rate up to 96% from ˜85% by general tourmaline materials and facilitate sufficient combustion by breaking fuel molecular group into pieces. As a result, the novel pipe can achieve an extra 12-percent fuel economy improvement. The percentage of toxic gas in the exhaust will be correspondingly reduced.
