Fuel-efficient and fuel-saving device

Abstract

A fuel-efficient and fuel-saving device is provided and includes a first fuel-modification device, an air-refining device, and a tubing-type fuel-modification device. The first fuelmodification device is arranged [በ 8 fuel tank. The air-refining device is arranged under ዷ filter screen of ፳ከ air filter of ፳ከ intemal combustion engine, and the tubing-type fuelmodification device is arranged above a pipeline between the internal combustion engine and the fuel tank. The first fuel-modification device includes a first metal box body and a plurality of nano far-infrared ceramic partices. The surface of the first metal box body has ዉ plurality of uniformly arranged air holes. The plurality of nano far-infrared ceramic particles is arranged in the first metal box body. The ball diameter of the nano far-infrared ceramic particles is larger than the diameter of the air holes.
