Nanotechnology is the study and application of materials at the scale of 1–100 nanometers, where they exhibit unique and superior properties. At this level, carbon can emit far-infrared rays that support blood circulation, while nanoparticles in energy can break down fuel molecules for more complete combustion, reducing emissions and saving fuel. With these advantages, nanotechnology is considered a key to the Fourth Industrial Revolution, with wide applications in healthcare, environment, and daily life.

FECO X3 significantly reduces harmful emissions such as CO, HC, black smoke, and unpleasant odors, contributing to environmental protection and user health. Thanks to nano semiconductor technology that breaks down fuel molecules into smaller particles, the combustion process becomes more complete, saving 10–25% of fuel while helping the engine run smoother, cooler, and last longer. The product is compact, easy to install, durable for 5–7 years, and delivers a safer, smoother driving experience for every family.
