In this video you will see the comparison between 1D piston and ordinary piston. We will introduce it from the following four aspects: 1.1D piston is made with equipment imported from Japan. It is more refined than ordinary equipment, the production process is also better, and the piston quality is better. 2.1D piston is precision processed, the combustion chamber is clean and bright, and the combustion is more thorough. 3. Using surface tin plating process, the color is brighter, the appearance is better, it is more resistant to high temperature and oxidation, and it has a longer life. 4. The inside of the piston has also been coated, making it more refined and smoother, and the internal metal patches are also tight. 5. Produced using Japanese forging technology. In terms of raw materials, imported ZL109 and aluminum alloy Arroy are used, which have higher tensile strength and high temperature resistance and are not easy to deform.
