Presentation Description

The piston rings are used to regulate the oil pressure as well as the quantity of oil consumed by the engine. These rings help for lubrication, heat transfer and even support the pistons. Being a vital part of the engine, you must take a look at the following slides to know all about the functions of the piston rings.

Slide1:

Things to Know About the Piston Rings

Slide2:

The engine inside your car contains a series of rings that are called piston rings which regulate the oil pressure and the amount of oil consumed by the engine.

Slide3:

The piston mainly consists of three rings: compression ring, wiper ring, and oil ring.

Slide4:

These rings are mainly made of cast iron of fine grain and sometimes by alloy steel.

Slide5:

Functions of piston rings

Slide6:

The main functions of the piston rings are listed below. 1-Compression gas sealing 2-Proper Lubrication 3-Heat Transfer 4-Support the piston

Slide7:

Compression gas sealing

Slide8:

The piston rings seal the cylinder so that combustion gas generated at the time of ignition does not leak through the opening between the piston and the cylinder.

Slide9:

Such gas leaks results in low output power from the engine and also increases the fuel consumption.

Slide10:

Proper lubrication

Slide11:

Due to repeated gas ignition, the pistons move up and down inside the engine at a rate of several thousand times per minute

Slide12:

Piston rings adjust the amount of oil to be poured over the pistons so that they move smoothly with minimum friction.

Slide13:

Heat transfer

Slide14:

During ignition, there is an extreme rise in the temperature inside the piston and such accumulation of heat may damage the engine.

Slide15:

The piston rings help to release the build-up heat through the engine walls and fins.

Slide16:

Support the piston

Slide17:

It is required for the piston to not to incline inside the cylinder and come in contact with the other parts of the engine.

Slide18:

The piston rings support the piston to allow for a smooth up and down motion without getting in touch with the engine wall.

Slide19:

Symptoms of bad piston rings

Slide20:

The common symptoms of the presence of bad piston rings in the engine are as follows: 1-More Exhaust Smoke 2-Weak accelaration Power 3-Need of more engine

Slide21:

More exhaust smoke

Slide22:

When there is a lot of exhaust smoke coming out of the car, it could be the result of bad piston rings.

Slide23:

Bad piston rings allow the engine oil to leak into the combustion and burn to form a thick gray and white exhaust smoke.

Slide24:

Weak acceleration power

Slide25:

When the piston rings suffer wear and get damaged, the engine will lose its power due to the decrease in compression.

Slide26:

So, when you press the pedal for acceleration, the car will take a long time to attain the power and speed up.

Slide27:

Need of more engine oil

Slide28:

The presence of worn piston rings allow the engine oil to leak into the combustion chamber, resulting in less oil in the engine.

Slide29:

In such drip in the oil level, there is need of regular addition of the engine oil in order to avoid serious engine problems.
