Piston rings are an important component of MTU (Mechanical Turbine Unit) engines.

They are responsible for sealing the combustion chamber and preventing oil from leaking into the combustion chamber.There are several different types of piston rings used in MTU engines, including:

  • Compression Rings: These rings are located above the cylinder bore and compress the air-fuel mixture as it is ignited by the spark plug.
  • Oil Control Rings: These rings are located below the compression rings and help to control the amount of oil that enters the combustion chamber. They prevent oil from leaking past the piston and into the combustion chamber.
  • Top Rings: These rings are located above the oil control rings and help to seal the top of the combustion chamber.
  • Bottom Rings: These rings are located below the oil control rings and help to seal the bottom of the combustion chamber.

It is important to regularly inspect and replace worn or damaged piston rings to ensure optimal engine performance and prevent any potential issues with oil leakage or combustion inefficiencies.
