Types of Cylinder Liners

A cylinder liner is a cylindrical part to be fitted into an engine block to form a cylinder. It is one of the most important functional parts to make up the interior of an engine.
This is called Cylinder liner in Japan, but some countries(or companies) call this Cylinder sleeve.These are main functions of Cylinder Liners.

Cylinder liners are the interior metal components within the piston that protect it from the wear and tear of the operation of the motor. Three basic types of liners are used: hot, dry and finned. The purpose of each type is to protect the piston from heat and impurities using slightly different methods. Cylinder liners are expensive, precisely manufactured products and are primarily purchased from specialty shops.

A cylinder wall in an engine is under high temperature and high pressure, with the piston and piston rings sliding at high speeds. In particular, since longer service life is required of engines for trucks and buses, cast iron cylinders that have excellent wear-resistant properties are only used for cylinder parts.

Also, with the recent trend of lighter engines, materials for engine blocks have been shifting from cast iron to aluminum alloys. However, as the sliding surface for the inner cylinder, the direct sliding motion of aluminum alloys has drawbacks in deformation during operation and wear-resistance. For that reason, cast iron cylinder liners are used in most cases.

Dry Cylinder Liners

Dry cylinder liners are among the basic piston protectors. They must withstand extremely high temperatures and guard against impurities, so they are constructed of high-grade materials, such as cast iron and ceramic-nickle plating. Dry liners are much thinner than their counterpart, wet liners. They do not interact with the engine coolant but instead provide a very close fit with the jacket in the cylinder block to protect the piston from heat and impurities.

Wet Cylinder Liners

Wet cylinder liners protect the pistons in a different way than dry ones, but they are made from the same hardy material. They come in direct contact with the engine coolant. Sometimes the wet cylinder liners are fitted with tiny openings to help disperse the heat and impurities. These types of liners are called water-jacket liners but are simply another type of wet cylinder liner. If the liner doesn’t have a cooling jacket, one is created by the liner by interacting with the jacket present in the cylinder block.

Finned Cylinder Liners

Finned cylinder liners are constructed of the same type of heat and impurity-resistant metal. This type of liner is designed for the air-cooled engine, and in operation works much like the dry cylinder liner in that the cooling medium for the motor is air. However, these liners are fitted with tiny fins which allow the inflowing air to draw with great force around the cylinder to provide cooling.

Three types of brief introduction of cylinder liner

 

Dry cylinder sleeve piston protector is one of the basic. They must be able to withstand high temperature, to prevent impurities, so they were built in high-grade materials, such as iron and ceramic nickel plating. Dry liner than their opponents, wet lining much thinner. They do not interact with the engine cooling water, but with the jacket very closely matched in the cylinder body, the piston to protect from heat and impurities.
Wet Cylinder Liner protection in a different way than the piston, but they consist of the same cold material. They are in direct contact with the engine cooling water. Sometimes, wet Cylinder Liner with a small opening, to help disperse the heat and impurities. These types of lining called jacket lining, but just another type of wet Cylinder Liner. If the lining does not have the cooling sleeve, 1 is composed of liner created by and in the cylinder body jacket interaction.
Heat and impurity finned cylinder sleeve structure of the same type of metal resistant. This type of liner is designed for air-cooled engine, and the operation is very like a dry Cylinder Liner, the air cooling medium motor. However, these lining are equipped with fin tiny, allowed to flow into the air and the cylinder around the great pressure plotted to provide cooling.

How Cylinder Liner Lubrication Perform Inside Engine?

 

Piston moves to and fro inside a cylinder and engineers have employed many piston rings inside the grooves on the piston that perform several tasks, including pressure sealing inside the combustion chamber. The speed of rubbing (friction) between the cylinder liner and piston rings is high. Other than this, there are extreme temperature conditions, pressure, and corrosive gases within the combustion chamber to which any lubricating oil between the piston and the liner would be used to.

Jaidarshan Indocraft Pvt. Ltd is equipped with several components that are in relative motion that can be different kinds- sliding, rotary, or oscillatory. Lubrication is a critical step to make the performance of the device smoother and prevent wearing of the components and damage.

Cylinder liners are also known as sleeves by many in the industry. A cylinder liner is basically a hollow shell that works as an enclosure during combustion of an engine. Although, cylinder liners are hollow but they are very robust in nature to withstand the huge fluid pressure in a successful manner.  The temperature difference between the inner and outer temperature of these cylinder liners vary greatly and this result in a great thermal stress that eventually these have to bear. There are now many Indian auto part exporters that are now exporting these liners also in the overseas market.

Are cylinder sleeves bad for your BMW engine?

 Are cylinder sleeves bad for your BMW engine?

2

 

 

There seems to be a bit of controversy surrounding cylinder sleeves and BMW engines.  Oil consumption, excessive noise, sleeves dropping, Alusil blocks not liking sleeves – you name it.  I took some time to talk to our machine shop foreman, (the man with 50 years experience) Tony (VAC owner) and our manufacturing partners (Darton and LA Sleeve) about the drawbacks of using sleeves in the S54, S62 and S65 engines.

Short answer:  There are no drawbacks.

Long answer:  I can say with absolute confidence that properly specified sleeves installed properly will work flawlessly and offer more durability than a non sleeved block.  Track builds, street builds, stroker builds, big HP forced induction builds – not a problem.  We have sleeved dozens of  BMW engines in our machine shop and sold 100s of BMW sleeves to machine shops all across the world.  We always have a few shelves full of BMW sleeves ready for shipment.

Some quotes from our partners:
“The only drawbacks we are aware of are poor installation practices.  It’s the primary reason for almost every issue possible.  Let me address that first: by adding a foreign object to the block, which had nothing in it to start with, logic would say the block has been compromised.  That can be true if done incorrectly.

Oil consumption is a myth.  In many cases, oil consumption will increase as a result of sleeves because of an incorrect hone pattern.  But, noise isn’t a myth.  If the sleeves are installed with too much piston to wall clearance, it usually sounds louder during warmup.  It sounds louder as a result of iron lining the cylinders.  Only way to prevent that is to watch the piston to wall clearance during the honing of the sleeves.

Only other issue is the sleeves dropping – It’s rare but possible.  Easily preventable, as long as they’re installed properly.  Only thing that can drop the sleeves, even after perfect installation, is bad aluminum and/or when a block is overheated all while the head has been over-torqued.  What we’ve seen happen when a block is way over torqued, and a customer is paranoid about head gasket seal, they’ve over-torqued their head thinking it will seal water.  So, when the heat expands the block, the block will pull away from the head.  As that happens, the expansion along with the over-torqued head, it will actually push the sleeves down because the sleeves seem to rise at the same time.  Very rare, but again possible.”

For all builds, we take it one step further by using flanged sleeves, built to our exact specs.  These flanges assure that the sleeve will not ‘drop’ under any circumstances.  See pics below.

“When some mechanics or engine builders look at the deck of the S65, they think there’s no room to put sleeves.  Although the S65 does not have thick walls in between cylinder bores, it does have one good quality – hard aluminum.  If the sleeves are installed properly, the block looses no structural integrity.  Meaning, the performance sleeves are quite thin, but radically stronger than the S65 aluminum. Therefore, by installing the thin wall sleeves properly, the great S65 block is now much more receptive to higher volumes of boost than the S65 alloy can handle.  By simply lining the block with the thin wall, centrifugally spun-cast ductile iron sleeves, the cylinder bores can handle 50% to 70% more boost than that of the Alusil aluminum bore block.

The boost can care less what pistons it runs with in most cases.  It’s the cylinder block walls that are compromised first, not pistons.  If the S65 block aluminum is poor, it will fracture the block well before the pistons fail.  That’s why we like to re-sleeve these alloy blocks ductile iron material.  Not to save the pistons, but so the block can hold compression so the pistons do their job properly.

There are several reasons for using cylinder sleeves. Most commonly they are found in manufactured aluminum blocks because as you know aluminum does not have the wear or sealing properties needed unless it is coated.

In higher performance applications a ductile iron sleeve is preferred since they are at least twice the strength of a standard cast iron sleeve.  If the sleeve is designed properly to fit the block the strength can actually be increased in the bore and ring seal is greater. You will also be able to run any style piston and ring that best suits the application. In some cases sleeved blocks will allow you to achieve a larger bore size or clean-up any damage that may occur. They can also be replaced in most cases.”
