Hyundai Getz>> The engine>> The block of cylinders
Features of the device
The block of cylinders of the engine is shown on fig. 2.1.
The block of cylinders is cast from special низколегированного pig-iron. Diameters of cylinders are broken into classes. The cylinder class is branded on the bottom plane of the block of cylinders.
Possibility расточки cylinders under the repair pistons increased on diameter is provided.
Covers of radical bearings are processed together with the block of cylinders, therefore they невзаимозаменяемы and for distinction have labels of an external surface.
Check
Carefully wash up the block of cylinders, clear lubricant channels.
Having blown and having dried compressed air, examine the block of cylinders. Cracks in any places of the block of cylinders are not supposed.
If there is a suspicion on hit of a cooling liquid in картер the engine check up at the special stand tightness of the block of cylinders. For this purpose, having muffled apertures of a cooling shirt of the block of cylinders, submit to it water of a room temperature under the pressure of 0,3 МПа (3 kgs/sm 2). During 2 mines it should not be observed leaks of water from the block.
If oil gets to cooling liquid without full dismantling of the engine check up, whether there are no cracks at the block of cylinders in zones of oil channels. For this purpose merge a liquid from cooling system, remove a head of the block of cylinders, fill a shirt of cooling of the block of cylinders with water and submit compressed air to the vertical oil channel of the block of cylinders. In case of occurrence of vials of air in the water filling a shirt of cooling, replace the block of cylinders.
Check up a plane of a socket of the block of cylinders a head of the block a ruler and a set щупов. The ruler is established on plane diagonals in the middle, in a longitudinal direction and across, the planeness admission makes 0,15 mm.
Examine cylinders.
Measure diameter of each cylinder in the top, average and bottom its parts in parallel an axis of a cranked shaft.
Measure diameter of each cylinder in the top, average and bottom its parts of perpendicularly axis of a cranked shaft.
Конусность the cylinder ovality – as a difference between parallel and perpendicular gaugings is calculated as a difference between top and bottom in diameters.
If the received results do not coincide with technical requirements, address to experts.
Step deterioration in the top part of the cylinder leaves by means of development.
In spare parts pistons of four repair sizes are delivered.
The repair sizes and marks of pistons:
Increased by 0,25 mm..... 0,25
Increased by 0,50 mm..... 0,50
Increased by 0,75 mm..... 0,75
Increased by 1,00 mm..... 1,00
At расточке cylinders till the repair size it is necessary to keep a demanded backlash between pistons of the repair size and cylinders and to establish pistons of the identical repair size.
Diameter of the piston is measured on distance of 47 mm from the piston bottom at right angle to lugs.
Backlash between the piston and the engine cylinder, mm:
In working volume 1,3/1,1 l..... 0,02–0,04
In working volume 1,5 l..... 0,02–0,04
In working volume 1,6 l..... 25–0,045
