Of course, every car owner would like to increase the capacity of its vehicle in combination while maintaining the normal quality of work. This is feasible using the cylinder block boring. The machine with a powerful power unit will immediately show itself on the road. To date, this event is quite popular and make it in every city. However, the boring is not so easy to do. To perform it, it will takes special equipment and skills. About this further in the article.

Wear block of cylinders, which affects the wear of the cylinder block

In the process of operation of the power unit on its parts, the load is constantly affected. As a result, gradual wear of the elements occurs. Since the loads in the motor are changing, the cylinder begins to acquire an uneven shape. It is easy to determine using special equipment, but not visually. The piston as a result of deviations on the trajectory can move to the side, and not only up. Because of this, the cylinder has the form of an ellipse (in a longitudinal section). The combustion products also affect the form of cylinders.

In this case, the replacement of the piston to the new will not help. To ensure reliable operation of the motor, such a procedure was invented as a boring of the cylinder block. Milk them due to the substantial wear of the inner surface. To determine the wear, a special degree of evaluation was developed. With the appearance of wear, corresponding to these estimates, it is necessary to perform a boring.

Due to the fact that the cylinder has the form of an ellipse, the piston rings are poorly adjacent, which entails the high consumption of engine oil. In addition, the power unit begins to lose compression, resulting in a serious breakdown, eliminate which will not work. It is very difficult to produce a boring yourself. For the entire event, at least the machine will be required. But it is better to entrust such work with mechanics with relevant experience and qualifications. It is worth noting that the quality of the motor boring directly depends on the qualification of the wizard and the presence of the required equipment.

Signs of wear block of cylinders, how to determine

The first sign of wear is the change in the initial size of the piston ring. If the size changes even by five hundred millimeters, the cylinder should urgently clean. The second feature is the change in size at the points of contact with the cylinder walls with a piston skirt. In this case, even the presence of deviations for three tenth millimeters from the norm is fraught with consequences. As it was already mentioned above, it is impossible to catch such changes to the eye. The presence of wear of the cylinder block is determined using special equipment.

Cylinder block boring, which gives a boring of a block of cylinders

The boring is required to increase the power of the motor. This event gives a power unit the opportunity to get the same size in the block, as well as the symmetric ratio of the holes in it. An additional resource arises that increases the safety of all elements of the motor. In addition, the friction of the piston rings on the wall of the cylinder is reduced, which positively affects the work. As a result, it does not appear enhanced oil consumption. The car behaves better on the road, which gives the driver of confidence.

Positive moments of boring block of cylinders

• Engine power increases.
• Compression increases.
• The car begins to behave better on the road.
• An additional resource appears.
• Movement oil consumption becomes optimal.

Negative moments of boring block of cylinders

1. Because of the borsk, the walls of the cylinders become a little thinner. Because of this, during the operation of the power unit, piston rings may overheat.
2. As a result of an increase in the working volume of the motor, the efficiency of the vehicle is falling.
3. There is a risk that problems may occur during the passage of what is due to discrepancies with the factory motor parameters.

How to make a boring block of cylinders professionals

The entire procedure requires the required measurements in order to establish the degree of damage. The boring is eliminated with the taper and ellipse form of cylinders. The procedure requires compliance with all the required conditions and special care. The boring is carried out during major repairs. You need to install the motor exactly without mesh, as this may significantly affect the result. The operation is carried out using a special cutter. A vertical machine is used for boring.

When performing work, everything is controlled using special measuring instruments. Thicketing behind the boring there is honing. Make it on another special machine. As a result, the surface of the cylinder receives additional smoothing.

Methods of boring block of cylinders do it yourself

There are two methods on self-boring of the cylinder block. Methods are complex, therefore requires a lot of effort and free time. Experts advise boring on a special machine.

1 way

For the boring, the usual powerful drill will be needed in the first way. It is necessary to work in such a sequence:

• We take the old unnecessary piston and make a kind of nozzle on the drill out of it. However, pre-cut the incision and wrap the piston of sandpaper.
• Install the cylinder on a flat surface and secure it so that it does not move.
• Put the resulting nozzle on the drill and turn it on on small revolutions.
• We spend the boring cylinder moves up-down. However, make sure that the sandpaper does not fly off the nozzle.

2 way

This method provides a boring with a wooden mandrel:

• It will take an appeal to a specialist to make a mandrel at the required dimensions.
• We supply with a saw or a junction of an incision depth to one centimeter for mounting sandpaper.
• It is necessary to pre-purchase emery paper with small and large grain.
• We establish sandpaper and move to the grinding procedure. We need to make paper with lubricant.

It is worth noting that it is not always an independent boring brings noticeable positive results. Therefore, it is advisable to contact professionals, which will save your time and strength to save.
