Piston with alfin reinforcement are resistant to compression ring groove wear. In order to reduce the intense heating of the first ring groove by the gas, the piston of the diesel engine is usually equipped with a spiral shallow groove around the fire bank to reduce the gas channeling along the gap between the piston and the cylinder liner by using the labyrinth step-down principle. In order to prevent the top ring carbon and adhesive, and the requirements of the first ring groove temperature can not be too high, for this reason, in addition to the use of ring groove set ring, the fire bank has a long trend, and the higher the degree of reinforcement, the more obvious the trend. There is a tendency to increase the height of the fire bank, especially the semi-separated combustion chamber diesel engine with the combustion chamber arranged in the piston roof. Therefore, instead of increasing the number of piston rings, it is better to take measures to improve the performance of piston rings, with a compression ring and two oil ring grooves to ensure the completion of sealing gas and oil control. It was found that more than one compression ring was not necessary, because if the upper compression ring failed, the other compression rings could not seal the gas in the combustion chamber from leaking into the crankcase, nor could they control the oil up the cylinder wall into the combustion chamber. From the 30 s 5~6 ring groove development to 2~3 ring groove. In recent years, in order to reduce the friction work, improve the mechanical efficiency, reduce the ring height and shorten the piston compression height and total height, the number of piston rings is decreasing. Nitriding: The nitriding products have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance. Moly Skirt : Help produce less frictional heat and engine noise. Piston type and surface treatment : Alfin ReinforcementĬreated for operation in high temperature environment like turbo engines.
