Information

One is to observe from the back of the Carrier 06E piston kit (the opposite side corresponding to the top), the back of the piston with high silicon content is darker, and the inner side has a very clear manufacturer's logo. And the silicon content of the fake piston is very low, the color of the back of the piston is white (pure aluminum white);

quality Carrier 06E piston kit

Second, the carrier 06E piston kit produced by regular manufacturers has high density, and its proportion is larger than that of fake and inferior pistons. Therefore, the easiest way to identify is to put the accessory piston and the piston produced by the regular manufacturer (must be the same model, the same displacement, and basically the same size) on the electronic scale, and you will see the difference.

The carrier 06E piston kit generally has grouping marks on the top, usually A, B, C and D groups, which are the size grouping marks of the piston skirt. In addition, the piston skirt has a number of very fine grooves, which are mainly used to store lubricating oil to enhance the lubrication function of the piston skirt. Defective pistons cannot be processed with such precision due to rough machining.

The high-quality Carrier 06E piston kit has very thin skirt walls and uniform wall thickness. The vernier caliper can be used to measure the unilateral dimension of the piston skirt. If the digital vernier caliper is used for measurement, the measurement result is more accurate due to its high precision. If the difference in wall thickness is more than 0.20mm, after the piston temperature rises, due to the different wall thicknesses of the skirt, the thermal deformation is large and uneven, so that the size of the piston skirt cannot reach its ideal perfect circle, which is not only prone to leakage , and an abnormal knocking sound will be produced.

The third is that the skirt of the regular manufacturer Carrier 06E piston kit has a non-circular cross-section. The cylindrical part from the bottom ring groove (referring to the oil ring groove) of the piston to the bottom of the piston is the piston skirt. Its function is when the piston reciprocates in the cylinder. It acts as a guide and bears lateral pressure during exercise. The piston in the non-working state is different from the working state under force and heat. This is because the piston will deform to varying degrees when it is heated and stressed.
