PISTON RINGS: THE ACHILLES HEEL OF ENGINE
PISTON RINGS: THE ACHILLES HEEL OF ENGINE
Piston rings work in high speed, pressure and temperature situation. It is the most critical component in internal combustion engine. Its tribological performance minimises frictional loss in engine cylinder, improves fuel and oil consumption and reduces harmful exhaust emissions.
BASIC ROLE OF PISTON RING SET
The basic roles of the piston ring set, the collective name for the three or more rings mounted on the piston, are to form an effective gas seal between the combustion chamber and the crankcase, to limit the upward transport of oil from the crankcase to the combustion chamber and to provide a flow path for heat transfer from the piston to the engine coolant. All this must be achieved with minimum frictional power loss, most notably at the sliding interface with the cylinder wall, and the least possible wear in order to maximise component life.[i]
MANUFACTURING OF PISTON RING
The Piston Ring set is the Achilles heel of engine. Being exposed to strenuous working condition, it’s more likely to get damaged. They are usually made of cast iron and steel. Wear resistance is an important requirement in the materials used for their manufacture. The material should also have a low friction coefficient to enable the rings to slide along the cylinder’s surface and should be able to withstand high pressures at various temperatures under limited lubrication conditions
PROTECT YOUR ENGINE WITH HIGH QUALITY PISTON RINGS
Considering the critical role of the rings, you should always consider high quality brand for your engine. The substandard rings could only withstand a few hours of operational engine. They reduce the life of engine from thousands of hours to less than 100 hours. If the engine is working in high RPM, like in Gensets, the life would be much shorter. HDP piston rings are manufactured with perfect geometry and material that they can be interchangeably used with the OEM rings. They can endure extreme working conditions like pressure and temperature and are also wear resistant. HDP also provide a cash back guarantee of 1000 hours. You can count on HDP ring for the long life of your engine.
