Adjusting valves on Daewoo Matiz injector. Adjusting Matiz valve, possible problems and solutions

17.05.2020

Compact little bars Daewoo Matiz Known primarily by their economy, and therefore low operational expenses. But in order for the technical potential of the machine to remain at the proper level, it is necessary to conduct a periodic inspection and adjustment of the settings of the GDS mechanisms.

When you need adjustment of valves on the car Daewoo Matiz and why?

Almost any engine through a certain number of worked motoes or kilometers passed requires adjustment of the gaps between the rocker and the valve rod. Regulations technical work Matiz Matiz service provides for such events every 20,000 km.

According to experts, valve adjustment on Daewoo Matiz Need due to the following factors:

increased thermal gap causes a decrease in lifting height, and hence the conduction section, as a result of which the high-quality filling of the cylinder of the combustible mixture or air is reduced;
reduced gap helps to disrupt the tightness of the landing of the valve in the saddle, which directly affects compression and causes burning chamfering parts;
an increase in the gap in the mechanisms implies the deterioration of cylinders from gases and makes an infallible process of combustion of the mixture.

Violation of technological sizes in the GDM mechanisms leads to the wear of valve rods and seating details. Nagar deposition and associated faults of spring structures leads to a violation of the working cycle of the power plant.

Determine the moment when the valve adjustment is necessary on the Daewoo Matiz car will help the presence of the following features:

power drop;
ringing knock in the Tyrrh area;
interruptions in the work of the engine;
periodic cotton in the intake or graduation path.

The presence of listed symptoms require immediate interference, otherwise the breakdowns associated with the replacement of the GDM assemblies will need significant financial influxers.

Preparatory work

First of all, you need to remember that all adjustment works are performed on a cold engine. Now complete the set of the required tool:

a set of horn keys;
screwdriver kit;
set of heads;
passatia;
set of imbus keys;
set of measuring probes.

The procedure for adjusting the gaps requires a number of preparatory activities, because it will not be able to get to the GDO knots. First of all, you should disconnect the minus wire of the AKB.

Removing the air filter hull

The process consists of several transitions:

Using a flat screwdriver, weaken the coat fastening clamp.
Disconnect the filter nozzle from the duct.
For the Matiz Matiz 0.8 l disconnect the shoe of the motor control system and the air temperature sensor, remove the hose from the filter housing.
Head to "10" unscrew the three bolts of fastening the filter housing to the air intake and remove them.
Raise the housing with air intake and resonator and output two pins from rubber pillows.
Dismantle the node.

Disassembling block of ignition coils

The following procedure, without which the valve adjustments on the Daewoo Matiz is not possible, is performed according to the scheme:

Squeeze the lock of the knob of the knoss control system.
Remove the block from the ignition coil knot.
Sliding the rubber caps from the conclusions of the coil block, disconnect the high voltage wires.
Using the head to "10", unscrew three bolts of fastening the coils and the bracket cover of the CHC.
Remove the ignition coil knot.

Dismantling throttle

The technological map of this process includes the following work:

Disconnect the ventilation tube of the crankcase from the duct nozzle.
Disconnect the housing air filter and remove the air duct.
Disable the wire terminals from the XX regulator (for Matiz 0.8 l).
Disconnect the wires from the position sensor throttle valve.
From the expansion tank to drain Tosol to the MIN mark.
Passage to squeeze the clamps of the feed hoses coaching the throttle blocks and disconnect them.
Hexagon reveal the four fastener bolts of the throttle block and the intake manifold.
Remove the throttle assembly assembly.

Latest preparations

After implementing the items described above, you need to remove the top cover of the timing belt drive. To do this, dismantle the liners from the right front arch wheel and unscrew the four bolts of the cover of the cover by a wrench on "10".

Before the direct adjustment of the valves on the car, Daewoo Matiz remains several uncomplicated technological operations:

Passage squeeze the edges of the hose clamp of the liquefaction supply to the vacuum amplifier and move it further along the hose.
Remove the vacuum hose.
Remove crankcase ventilation hose from hbz cap fittings.
Using the hexagon on the "5" screw the screw of the intake pipeline bracket.
Squeeze the petals of the wiring control system of the DVS control system with a screwdriver and disconnect the harness from the bracket.
Unscrew the head on the "10" bolt fastening the connecting pipe bracket and take it to the side.
Unscrew 8 bolts of fastening the CHC cover using a hexagon on "5" and dismantle it.

How are the adjustment of the valve mechanism gaps on Daewoo Matiz?

We first find out that for inlet valves, the gap is 0.13-0.17 mm, and for the graduation - 0.3-0.34 mm. The probability of the required size should be moved in the interval with a slight force. Now you can proceed to adjustment works in stages:

Head to "17" clockwise Turn the crankshaft before matching the tag on the pulley with the number "0" on the bottom cover drive belt Timing.
In this position, the gaps of the intake and exhaust mechanism of the 1st cylinder, as well as the inlet 2nd and graduation 3rd cylinder, are corrected.
In the case of deviations from the recommended dimensions, it is necessary to loosen the control of the wrench to "12", while while holding the adjusting screw with a slotted screwdriver.
Insert the probe into the gap and adjust the engine valve mechanism by spinning / unscrewing the adjusting screw with a screwdriver before obtaining the desired dimensional values. After that, tighten the lock nut while holding the screw with a screwdriver from turning.
Turn the shaft to 360 ° so that the blue label on the camshaft pulley coincided with the triangular label on the bottom cover of the timing belt.
Check and adjust the gaps of the following valve mechanisms: the outlet 2nd and intake 3rd cylinders, as well as the inlet and exhaust 4th cylinder.

After completing the adjustment work, all dismantled nodes and aggregates are installed in the reverse order.

The car Daewoo Matiz has a small enough, and therefore economical engine. But sometimes, in the stream, it is necessary to set gas in order not to fall out of the total mass of motorists. To maintain the engine in working condition, it is necessary to regularly check its condition. It is also important to periodically adjust the operation of the GDS system.

What time is it desirable to adjust the valves on Daewoo Matiz?

Adjustments of the gaps of this mechanism requires each OI. Adjusting valves at Daewoo Matiz is recommended to spend every 20 thousand kilometers.

Specialists talk about the following factors indicating the need to adjust the valve:

Advanced thermal gap will cause a decrease in lifting height and passage. In this regard, the engine gets less fuel and air.
On the contrary, the reduced thermal gap violates the impenetability of the landing of the valve in the saddle. This can lead to the burning of the chamfer, which, in turn, will negatively affect compression.
The cylinders began to be worse from gases, and the process of burning the mixture became poor, if the gaps increased.

In case, in the GDM system, the dimensions specified by technologists, the rods of the valves and landing sites of the engine parts wear out. A climb and damage to the parts with springs associated with it can cause the engine.

Signs that will help to understand what time it is time to adjust:

The engine has fallen;
In the GDG region, a ringing knock is heard;
There are interruptions in the engine;
Periodically arise cotton at the inlet / release.

If you do not start any fault data repair work In the near future, it will cause serious money in the future.

Therefore, let's consider the order of adjusting the valves of Daewoo Matiz.

Preparatory stage of work

It is important to know that the valves should be adjusted only with a cold engine.

The tools must be logged in:

Wrench keys (they are horn) - set;
Screwdriver kit;
Set of end heads;
Imbus keys (set);
Measuring probes;
Passatia.

To get to the valves, you need to make some preparatory work.

It is necessary to de-energize the battery, observing safety equipment. To do this, disconnect the wire minus from the battery.

For this we do the following:

The air duct is fastened with a special clamp, weakening it with a flat screwdriver.
We take the filter pipe that is air, and disconnect from the duct.
With the air filter housing we remove the hose.
If the engine of your car has a volume of 0.8 liters, then a block of harness of the electronic engine control system is separated from the temperature temperature.
The filter housing is attached to the air intake with three bolts. The end head on the "10" turn them off.
Lightly raise the air intake and the ball, we take pins from special rubber pillows.
Disassemble a node.

Now remove the ignition module.

Adjusting valves on Daewoo Matiz without this procedure is practically impossible.

Performing it, we do the following:

We find a fixer and press it from the engine of the engine horizontal system.
The coils are attached to the HBC cover holder to remove them, you will need to unscrew the three bolts with the "tenth" end head.
Remove the ignition module.
Now remove the throttle knot.

This action is also made in several stages:

From the duct tube, disconnect the crankcase ventilation tube.
Also, remove the hose leading to the air filter, after which you remove the air duct.
It is required to turn off all the wires from the regulator. idle move. This is applied to the engine of 0.8 liter matiz.
The throttle has a position sensor. Wires leading to it, too, disconnect.
Tosol must be merged to a minimum mark.
On the hoses that are served by the choke block, it is necessary to squeeze the clamps by pasati and disconnect them.
The throttle block and the intake collector have four fastening bolts. They need to be turned off using a hex key.
Now we can remove the entire throttle knot.

And the last thing you need to do right before adjustment.

When the work is completed, remove the cover at the timing belt. To do this, it is necessary to remove the front arches to the right and 4 fastening bolts.

Now there are some more simple operations:

A vacuum amplifier stretches the vacuum hose. It is necessary, with the help of the passage, clamp the clamp from the edges and move it along the hose.
Remove the pipe supply.
Remove the supply of a venting crankcase from the hbz cap fitting.
Inlet Pipe holder screws need to be unscrewed using a hex key to "5".
It is necessary to squeeze the petals of the fixing element of the wires in the control system power aggregate, with a screwdriver. From the holder, disconnect the harness.
With the end head on the "ten" unscrew the bolt, which fastens the bracket of the connecting hose and assure it to the side.
Remove the bolts (8 pieces), which are fixed with the GBC "fifth" hexagon key and disconnect it.

And now about the main thing: I give up the valve gaps on Daewoo Matiz

It is important to take into account information that for intake valves, the gap should be from 0.13-0.17 mm, and for release 0.3-0.34 mm. In this space, with some effort, the dipstick should move.

Further, stepwise proceed directly to the adjustment:

The seventeenth end head, in the direction of the clock arrow, turn the crankshaft, so that the mark on the pulley coincides with the mark "0" on the timing of the timing belt below.
In this position, the inlet / release gaps of the first cylinder, the inlet of the second, and the third cylinder release system are adjusted.
If you see that the dimensions do not coincide with the ideal, which experts recommend, you need to weaken the "12th" knockedy key.
The main thing is to hold the screw adjustment screw to the slope.
Insert the probe into the clearance and regulate the valve unscrewing / twisting the adjusting screw until the necessary values \u200b\u200bare obtained.
Next, tighten the control nut, in parallel holding the adjustment screw with a screwdriver.
Needed by turning the shaft, to achieve coincidence on the bottom cover distribution Vala., the blue label converged with the "triangle" at the timing belt on the lid below.
Now it is necessary to implement the regulation of gaps: the release of the second and intake of the third cylinders, and the inlet / release of the 4th.

Once all the valves on the matize are adjusted, you must install all the components of the engine elements in the opposite of the manual.

Before adjusting the thermal gaps on the valves, before they need to be reached. The disassembly begins with removing the block of ignition coils and throttle node.

To dismantle block ignition coils First you have to move the rubber protective caps from its conclusions, and after disconnecting the tips of the candle high voltage wires. Then the head "on 10" using the extension cable, it is necessary to unscrew the three fastening bolts that lock the coil block to the bracket of the cylinder head cover. The unit can be removed.

To remove throttle knot on Daewoo Matiz 1.0 l, you must first disconnect the wire terminal from the "minus" output rechargeable battery. A slotted screwdriver is weakened by a tightening of 2 clamps that lock the air duct with the throttle node pipes and the cover of the air filter housing. Further remove the air duct from the nozzles of the filter cover and the throttle node and take the air duct to the side. Disconnect the throttle cable from the drive sector.

Now you need to disconnect the block in which the wires are placed, from the throttle connector. To do this, you just need to push the pad to the lock, located below. Following two nuts (key "10) on the upper attachment of the throttle node. You can already remove the cable bracket for the throttle drive with the inlet pipes.

Two screws are turned on to top off (hexagon "on 5"), holding the lower fastening of the throttle assembly. The throttle node moves with studs. The adsorber blowing hose is disconnected from the fitting on the throttle housing and the throttle assembly itself is removed. Do not forget to remove the sealing gasket of the throttle knot flange. Note that in Daewoo Matiz 0.8 liters, the throttle node is removed in a small way.

After removing the throttle assembly, a dismantling queue was established top cover drive timing belt . Squeezing the ends of the hose fastening of the vacuum brake amplifier with the vacuum hose from the intake pipeline to the vacuum brake amplifier, clamping the hose. Now with a connecting tube you can remove the cutting hose. Further, the cylinder head cover covers the crankcase ventilation hose. The hexagon "on 5" turns out the screw fastening of the inlet pipeline with a connecting tube bracket.

On the subsequent step, disconnect the holder of the wiring harness from the bracket. For this purpose, the holder of the wire holder, which goes to the engine control system, is pretty compress a screwdriver. We turn around the head "on 10" fastening the connecting tube bracket. The connecting tube is assigned to the side without disconnecting the hose of the vacuum brake amplifier from it. We turn over the hexagon "on 5" eight screws fastening the cylinder head cover. Now you can dismantle the cover of the head of the cylinder block.

Remove dirt shield connected to the arch right-hand wheel. To do this, dismantle the right front wheel. From the bottom of the car with a cruciform screwdriver through a hole in the front stretcher turn the screw of the lower fastening of the shield. Head "on 10" turn the nuts of the upper and frontal mounting of the shield. All - the dirt shield is released.

Adjusting thermal gaps.

After removing the panel on Daewoo Matiz 1.0, the thermal gaps are already probable. For this, the piston of the first cylinder in the NTT is installed at the end of the compression tact. To achieve, turn the crankshaft clockwise (head to "17") for the pulley fastening bolt until the label is in the form of a cutout on the pulley crankshaft With a digit "0" on the bottom lid of the timing belt. It is necessary to watch that the label on the gear pulley of the camshaft was placed opposite the label in the form of a triangle on the rear lid of the timing belt. Having achieved this position of the crankshaft can already be inspected and adjust the valve gaps in the following order:

Intake and exhaust valves of the first cylinder;

Inlet valve of the second cylinder;

The outlet valve of the third cylinder.

Flat probe check the thermal gap between the valve terminal and the adjusting screw. With all this, the dipstick should move into the gap with a little effort. The magnitude of the gap should be in the permissible boundaries of 0.32 ± 0.02 mm for exhaust valves and 0.15 ± 0.02 mm for intake.

If the value of the thermal gap does not coincide with valid, then the tightening of the lock nut weakens with the key "to 12", with all this while holding the adjusting screw. Delay the screw is more convenient than the slotted screwdriver. To reach the desired gap, you need to stick the probe between the adjusting screw and the valve terminal, and then turn the screw with a screwdriver to suitable values. After - tighten the locknut, with all this, the adjusting screw is held with a screwdriver. At the end of the adjustment, you need to double all the gaps again.

We continue the adjustment. Turn the crankshaft 360 ° clockwise. With all this, the blue label of the gear pulley of the camshaft should set up opposite the triangular mark on the rear lid of the timing belt. In this position of the crankshaft, we check and as needed adjusting the gaps of subsequent valves:

Graduation second cylinder;

Inlet third cylinder;

Inlet and graduation 4th cylinder.

After the termination of the thermal valve gaps on the Daewoo Matiz 1.0 l, all removed nodes and parts are installed in the revolving sequence.
