YENMAK PISTON, LINER, RING

 

Our pistons which are used for billions of vehicle types worldwide are manufactured of aluminum ingots supplied from significant primary aluminum manufacturers. Piston manufacturing is carried out selectively by considering the significance of piston for engine and using computerized systems from manufacturing stages to quality control.

 

PISTON AND PISTON PIN

The piston is one of the most important movable components in an engine. It provides the required vacuum pumping (intake stroke) for fuel-air mixture in engine cycle to fill into the cylinder and compressing (compression stroke) to generate the required pressure for the mixture's self-ignition by making use of the inertial power of crankshaft. The chemical energy generated by ignition and explosion of compressed mixture is converted to a rectilinear motion by the piston (power stroke) and the engine is powered up. The exhaust gasses remaining in the cylinder as a result of ignition in the power stroke are swept (by boosting) and evacuated at exhaust by the piston by making use of the inertial power of crankshaft (exhaust stroke).

 

Rectilinear motion facilitated in the power stroke is converted to rotational motion expected from the engine by piston pin, connecting rod and crankshaft. Aluminum is preferred today as the piston material having the advantages such as providing heat conductivity, being pretty light, easy-to-cast and process. When the piston is at the working temperature, it is designed by calculation the expansion during the processing (when cold) to make it a full cylinder. For this purpose, the extreme expansions should be taken under control by processing cross sections on the piston at various diameters and oval shapes according to their material density and the temperature values to be exposed.

 

YENMAK LİNER

 

Piston, liner, and ring are the most important parts working in an engine synchronously.
YENMAK has been manufacturing dry and air cooled liners for any kind of vehicles since 1993.

The cylinders which are one of the motionless components of the engine are the components forming the outer frame of the engine revolution and guiding to the piston running way. In some of the engines, the cylinder liner is not designed as a separate part and the engine block itself is used as cylinder surface. In each case, the tasks expected from the cylinder are the same.

There is type of the cylinder to which is of water contact is called watered (wet) liner; the one not contacting water is called dry liner. 

The inner surface of the liner is the surface on which is the rings are fractioned that provide the sealing between the combustion room and sump. Thus; it needs to have a minimum friction and leaking characteristics. For this reason, the inner surfaces of the liners are honed and the honing channels are opened to in order to provide oil films and a sealing is ensured by reducing the friction.

Generally, lame graphite perlite cast iron is preferred as the liner material by evaluating the characteristics such as corrosion resistance, thermal conductivity, adaptation of the engine blocks, processing capability.

 

PISTON RING

 

It is an important component which provides the sealing between the engine combustion room and sump while the vacuuming, compression, explosion and sweeping processes are forming in the cylinder during the running of the motor.

Motor piston rings prevent the increase of the high temperature of the engine which occurs by the combustion of fuel by transferring to the cylinder and thus to the cooling water. The ignition piston ring is the one contributing the sealing most as it is exposed to the highest gas pressure effect. The pressure decreases on the subsequent piston rings. The reason for using the oil rings is to provide the scraping of the extra lubrication oil applied to the surface of the cylinder block or liner by hitting effect or mechanical lubricators to the sump and provide a thin oil layer on the liner surface.

Therefore, the danger of the extra lubrication oil to be taken into the combustion room and being combusted is prevented. At the meantime, the lubrication of the upper parts of the cylinder liner and compression rings is also constituted by these rings which are on the upper course of the piston in order to provide a better lubrication.

The numbers of the rings which are placed on the pistons can vary as per the engine types, revolution and powers. The use of 3-4-5 ringed Pistons is very common. Some of the rings have to scrape ratchets on them. The oil scraped by these ratchets is sometimes taken into the pistons and from there discarded to the sump.

The rings are manufactured in different designs as the cross section profiled and spring shapes ensuring the compression power as per the preference of the engine manufacturers.
