Hyundai Getz>> The engine>> Head of the block of cylinders
Features of the device
The head of the block of cylinders is cast from an aluminium alloy, has запрессованные pig-iron saddles and directing plugs of valves. The top part of plugs is condensed резинометаллическими маслоотражательными with caps.
In spare parts directing plugs with the increased external diameter are delivered.
In the top part of a head of the block of cylinders support under camshaft necks are located. Support demountable: the top half is in cases of bearings, bottom – in a head of the block of cylinders. Apertures in support are processed in gathering with cases of bearings, therefore they невзаимозаменяемы and a head of the block of cylinders it is possible to replace only in gathering with cases.
The mechanism of a drive of valves
Valves are put in action by camshaft cams through коромысла on the engine in working volume of 1,1 l, on other engines valves are resulted by camshaft cams through hydraulic pushers. Adjustment of backlashes in the mechanism of a drive of valves with hydraulic pushers is spent at engine work automatically.
Adjustment of backlashes in the mechanism of a drive of valves (only engines in working volume 1,1)
Adjustment of backlashes in the mechanism of a drive of valves is spent at engine work automatically. Additional adjustment of backlashes in the mechanism of a drive of valves while in service the car is provided only for engines in working volume of 1,1 l.
Warm up the engine.
Uncover heads of the block of cylinders.
Turning a cranked shaft in a rotation direction (clockwise if to look from a forward end face of the engine), establish the piston of 1st cylinder in position ВМТ of the end of a step of compression (fig. 2.7). In this position adjust backlashes in a drive of valves in following cylinders.

Insert щуп between an end face of the adjusting screw коромысла and an end face of a core of the valve. Adjust a backlash and tighten a lock nut of the screw.
Turn a cranked shaft on one turn in a rotation direction (clockwise if to look from a forward end face of the engine) before position ВМТ of the end of a step of compression of the piston of 4th cylinder. Inserting щуп between end faces of adjusting screws коромысел and end faces of cores of valves, adjust backlashes in a drive of valves in following cylinders.

Backlash adjustment between an end face of the adjusting screw коромысла and an end face of a core of the valve is shown on fig. 2.8.
After adjustment tighten lock nuts of adjusting screws (fig. 2.9). Adjustment of backlashes (tab. 2.2) spend at position of the piston of 4th cylinder in ВМТ the end of a step of compression.

Hydraulic pushers of valves

THE NOTE
Noise in газораспределительном the mechanism at engine start-up – the normal phenomenon. At the idle engine depending on position of cams from each pusher it is superseded various (большее or smaller) quantity of oil. It leads to noise occurrence until hydraulic pushers at the working engine will not be filled with oil. This process can last until the engine will not reach working temperature. For maintenance of excellent job of hydraulic pushers in a head of the block of cylinders it is provided oil заслонка, preventing a full devastation of oil channels in a head of the block of cylinders on the idle engine.
|
|
THE PREVENTION
At occurrence of knock of pushers at work of the engine do not suppose increase of frequency of rotation of a cranked shaft to 3000 mines-1 and more as it can lead to damage of pushers.
|
Check of hydraulic pushers of valves
|
THE PREVENTION
Hydraulic pushers of valves are necessary for checking up, if in газораспределительном the mechanism there are knocks and noise after achievement by the engine of working temperature.
|
Warm up the engine and leave it to idle, the radiator fan will not join yet.
Increase frequency of rotation of a cranked shaft of the engine to 2500 mines-1 approximately for 2 minutes
If hydraulic pushers of valves continue to rustle, muffle the engine and uncover heads of the block of cylinders.
|
THE PREVENTION
Do not rotate a cranked shaft for a bolt of fastening of a gear pulley of a camshaft as it is thus overloaded gear приводной a belt. Cranked and distributive shaft can be turned also as follows: establish the car on an equal surface, include the fifth transfer and shift the car a little, pushing it forward or back.
|
Turn a camshaft so that the cam of the checked cylinder has been turned upwards. For this purpose establish a transmission control lever in neutral position, tighten the lever of lay brake system and turn a suitable wrench a cranked shaft in a rotation direction for a bolt of fastening of a pulley of a belt of a drive of auxiliary units.
Press on a pusher a wooden or plastic wedge. If it is thus felt люфт as size more than 0,1 mm, replace a pusher.
|
THE PREVENTION
After installation of a new hydraulic pusher it is impossible to start up the engine during 30 mines, otherwise the valve plate can face the piston that will lead to their damage.
