What is the function of cylinder liner?

The cylinder liner, serving as the inner wall of a cylinder, forms a sliding surface for the piston rings while retaining the lubricant within. The most important function of cylinder liners is the excellent characteristic as sliding surface and these four necessary points.

What is piston liner?

Piston liners line the cylinder in which the pistons run. They are typically made of a more durable metal than the engine block itself and replacing them when they are worn can extend the life of your engine. Reduced wear on the cylinder.

What is a wet liner engine?

Wet type cylinder liners are the liner type in direct contact with the engine coolant. The wet liner is usually heavy and thick-walled. They are made of high-quality, alloy cast iron material, similar to the centrifuged casting method, such as dry type liners. They are in direct contact with the engine coolant.

What are piston liners made of?

Cylinder liners are generally made of closed grained pearlitic cast iron, nickel CI, nickel- chrome CI, cast steel and forged alloy steel. The inner surface of the liner is heat treated to obtain a hard and smooth surface.

How do you clean inspection Pistons and cylinder liners?

• Block the starting air supply to the main starting valve. • Open the indicator valves. • Engage the turning gear. • Remove the inspection covers on the camshaft side of the cylinder frame, and clean the openings. • Remove the cover (s) on the scavenge air receiver.

How to remove cylinder liners from a car?

Unbolt the connecting rods from the crankshaft. Remove the whole con-rod/piston/liner assembly. You didn’t mention this, so I’ll go ahead and ask… have you removed the big end caps (or taken the pistons out entirely)?

What do you need to know about piston inspection?

• Photos taken of piston crown, top land, piston rings, piston skirt, piston rod, cylinder liner, scavenge box and scavenge receiver. Before and after photos are required for any surfaces that are wiped down or cleaned, see Taking Photos Section for details. • Inspection of non-return flaps.

What does it mean when oil is found on a piston?

If oil found on the piston, determine if it is fuel or lube oil. Fuel oil will be black and sticky, indicating a fuel valve is leaking. Lube oil will be brown and non-sticky, indicating it could be from an exhaust valve. Piston Crown Condition 8. Water on a piston indicates a cooling system leak.
