Welcome to the channel of the company "AutoStrong-M".00:00:19
We have 200,000 excellent parts in stock, these are turbochargers, generators, gearbox engines.00:00:26
We have excellent service and fast delivery.00:00:31
Exactly two years ago, we disassembled our first motor with a pump nozzle.00:00:35
Today, two years later, we will make a complete guide on the problems of engines with pump nozzles.00:00:42
So welcome 1.9 TDI.00:00:48
The famous diesel engines from the VAG concern with pump nozzles were produced from 1998 to 2008.00:00:56
These are reliable and resourceful engines that have great potential for chip tuning.00:01:01
The technology itself implies that each nozzle is a high pressure pump and injector.00:01:09
Moreover, each nozzle has an electronic control.00:01:13
Engines with pump nozzles, in particular such 8-valve ones, were used on all brands of the VAG concern.00:01:20
From Beetle to Multivan, from Fabia to Suberpb, to Audi A3, A4, as well as to the Ford Galaxy, which is created on the Volkswagen Sharan platform.00:01:30
And today we look at the engines with pump nozzles on the example of this engine 1.9 TDI (BLT) 130 horsepower.00:01:39
This engine is virtually a copy of the 1.9 TDI (ANZ) engine.00:01:43
The differences are only in the EGR system.00:01:49
The main problems of engines with pump nozzles are associated with problems in the geometry of the turbocharger.00:01:56
Also, communication with the pump nozzles is lost.00:01:57
When using low-quality oil, the cylinder head, camshaft and pump nozzles suffer.00:02:05
And now more about this and everything else.00:02:08
There are many small reasons why an engine with a pump injector does not start well.00:02:16
If the engine does not immediately start on a cold one, then the reason may be related to airing and wear of the cylinder head.00:02:23
Next, we will talk more about this problem.00:02:25
Also, this engine may not start well due to a worn check valve, which is designed to stop the fuel drain from the mechanical booster pump.00:02:35
This valve is located in the tube after the fuel filter and passes fuel in one direction.00:02:42
Also, the engine will start poorly due to the presence of leaks on any fuel lines.00:02:47
Attention should be paid to all pipes, sealing rings and clamps.00:02:53
The 1.9 TDI engine vacuum system has two electrovacuum valves.00:02:59
They are essentially the same. They differ only in the diameter of the inner tube.00:03:03
One valve, called the N75, is responsible for the operation of the geometry of the turbocharger.00:03:09
The second valve N18 is responsible for the EGR valve.00:03:13
Due to drying out and loss of tightness of the vacuum tubes, the engine loses traction because the geometry of the turbocharger is disrupted.00:03:21
Also, these valves may become clogged and stop holding the vacuum.00:03:25
Also, the inner membranes may crack.00:03:28
But in the presence of sleight of hand, the valve can be disassembled, cleaned the inner tubes, change the membranes and thereby restore their performance.00:03:41
The coolant temperature sensor is important for proper engine operation.00:03:46
If the temperature sensor gives incorrect readings, then fuel consumption increases and engine starting deteriorates.00:03:52
You can evaluate the performance of sensors during diagnosis by actual parameters.00:03:57
An obvious sensor malfunction is indicated by inadequate engine temperature gauge data.00:04:05
The 1.9 TDI engines use a tandem pump with two sections.00:04:11
Vacuum section and fuel pumping section.00:04:14
Most often, this pump requires replacing a set of gaskets to eliminate fuel leakage.00:04:21
Also, there are frequent cases of fuel getting into the vacuum system.00:04:25
After that, the fuel is mixed with engine oil and then the liquid level in the sump increases.00:04:33
The opposite is often the case when oil enters the fuel.00:04:38
This is clearly visible when replacing the fuel filter.00:04:40
The fuel filter turns black due to engine oil staining.00:04:43
These problems with mixing fuel and oil are solved by disassembling the pump and replacing the shaft seal.00:04:51
By the way, this is not the only reason for mixing fuel and oil.00:04:56
On the vacuum section is an unsuccessful fitting, which is simply rolled.00:05:02
Over time, the rolling decreases and the vacuum disappears.00:05:06
The fitting begins to hang out.00:05:08
If the vacuum disappears or it does not reach the desired values of 0.6-0.8 bar, then problems appear in all systems that are associated with vacuum.00:05:18
Including problems with the brakes.00:05:20
In this case, the pump will have to be changed.00:05:22
Such a beautiful pump costs about $ 30.00:05:26
Or you can use welding. Argon welding will be expensive, but not always successful.00:05:33
Sometimes cold welding saves.00:05:36
The jump section is a pump with a pair of vanes, which are pressed against the rotor by two springs.00:05:44
Often these springs fall apart and fall into the cavity of the booster pump.00:05:50
There they come in contact with moving elements and cause damage.00:05:55
But before that, the engine will start poorly, because the required pressure of 7 bar will not be achieved immediately, but after several crankshaft rotations.00:06:06
It is not easy to repair the jump section, because the springs are not sold separately and must be selected.00:06:13
Therefore, it is better to buy a tandem pump at AutoStrong-M.00:06:19
The tandem pump is located here on the engine.00:06:22
Fuel through this hole enters the fuel rail, which is built into the cylinder head.00:06:30
Today, Nikolai will help us in disassembling this beautiful engine. Welcome!00:06:36
We begin our showdown.00:07:19
Since the 1.9 TDI (BLT) engine is designed for Euro 4 environmental standards, it is equipped with an EGR valve.00:07:26
With a heat exchanger in which the exhaust gases are cooled by antifreeze.00:07:31
Nearby is the metering flap, which is popularly called the "throttle".00:07:36
Electronic butterfly valve.00:07:39
The damper is needed in order to dose the exact amount of air and exhaust gases.00:07:44
It also closes the intake tract at the time of engine shutdown.00:07:50
In this embodiment, the EGR valve must be removed programmatically, although there are no problems with it.00:07:58
The EGR valve is easy to remove and clean.00:08:00
Also, the stroke of the damper may be disturbed.00:08:03
Because of this, engine errors appear.00:08:06
The plastic gear in the servo may also wear out.00:08:28
Most TDI engines with pump nozzles use the excellent KKK BV39A variable geometry turbocharger.00:08:39
The turbocharger is reliable. In most cases, he becomes a victim of external factors.00:08:43
For example, if there is a problem with lubrication, then the shaft and plain bearings suffer.00:08:49
This leads to a backlash of the entire rotor.00:08:51
In this case, disassemble the turbocharger and replace the cartridge.00:08:56
But why do this, if a wonderful serviceable turbocharger is waiting for you at AutoStrong-M.00:09:01
Most often, this turbocharger requires attention due to a violation of its geometry.00:09:07
The fault may be the very N75 electrovacuum valve that we talked about, or leaky vacuum lines.00:09:15
Also, geometry can wedge due to accumulated soot.00:09:19
There are rare cases when the membrane of a vacuum actuator is destroyed.00:09:24
And then the so-called "turboyama" appears in the behavior of the engine.00:09:28
Also, with such a problem, the geometry may not work at all.00:09:39
On engines with pump nozzles, a wide timing belt is used. Why?00:09:45
Because the camshaft not only opens the valves, but also presses the pump nozzles.00:09:50
Also note that the timing belt drives the pump.00:09:54
The camshaft pulley is here integral with screw mount.00:09:58
This mount is needed for finer camshaft timing.00:10:03
The timing parameters of the camshaft and crankshaft are visible in the diagnostic software.00:10:10
Deviations in synchronization must be zero.00:10:19
In the valve cover of this engine there is a membrane of the crankcase ventilation system.00:10:25
This membrane is needed in order to block the gas sampling channel at high discharge in the intake manifold.00:10:34
The membrane saves from excessive exhaustion of oil and gas vapors into the intake manifold.00:10:40
Often this membrane is clogged with soot and clots.00:10:44
As a result, this channel becomes clogged, the pressure in the crankcase rises, and this pressure begins to squeeze out the oil through all the seals.00:10:52
The turbocharger suffers, because the oil from the cartridge does not drain.00:10:58
This problem is not easy to recognize, as the pressure in the crankcase increases with constant load.00:11:04
For example, when driving on the highway.00:11:07
To solve this problem, remove the membrane cover, clean the membrane, or replace it.00:11:14
Experts also advise making a hole in the membrane about 2 millimeters in order to prevent clogging in the future.00:11:24
In the area of the electric circuit of the nozzles, which is located under the valve cover, the braid often falls apart.00:11:32
After that, some pump nozzles are turned off.00:11:35
Accordingly, some cylinders do not work.00:11:38
This fixes errors that indicate a failure in the nozzle circuit.00:11:44
These symptoms usually appear hot.00:11:48
When the engine restarts, these symptoms may disappear.00:11:52
To solve this problem, you need to change the entire part of the wiring under the valve cover.00:11:57
Also, sometimes the pump nozzles are switched off due to the lack of electrical contact.00:12:03
To solve this problem, you just need to tighten the contacts of the nozzles.00:12:09
The camshaft of engines with pump nozzles works with very high loads.00:12:13
This applies to all camshafts.00:12:17
Valve cams operate on poppet pushers with hydraulic compensators.00:12:22
And the cams of pump nozzles run through the rockers' rollers.00:12:26
To protect these friction pairs, special oils are used, oils with special tolerance Volkswagen 505.01 viscosity 5W-40.00:12:38
Change the oil at least once every 10,000 kilometers.00:12:42
Due to lubrication problems, the cams of the exhaust valves and their pushers wear out first.00:12:48
The more the cams are worn, the worse the exhaust valves open.00:12:55
Then the gases cannot completely leave the cylinders through the exhaust valves.00:12:58
In this case, the engine loses traction.00:13:01
Pulsations are also observed in the intake manifold, where gases from the cylinders break through the intake valves.00:13:06
Another reason for poor lubrication in the cylinder head is insufficient oil pressure.00:13:11
The fact is that very important channels are located in the axles of the rocker arm.00:13:17
Each channel is closed at both ends with aluminum plugs.00:13:22
Over time, these aluminum plugs fall out, and oil pressure escapes through the openings.00:13:28
To repair the cylinder head in many cases, it is enough to replace the camshaft, its liners and pushers.00:13:57
Each nozzle is equipped with a plunger that generates pressure in its own high-pressure chamber.00:14:05
The rocker is pressed onto the plunger, which is driven by the corresponding camshaft cam.00:14:13
During the movement of the plunger down, preliminary injection is carried out, then the main injection takes place.00:14:20
Fuel atomization pressure of the pump nozzle - up to 2000 bar at maximum load.00:14:29
Dosing of injected fuel is carried out by a solenoid valve.00:14:34
At the command of the computer, the valve blocks the outflow of fuel from the high-pressure chamber.00:14:41
Thus, controlling the ECU valve needle, it regulates the amount of fuel injected.00:14:49
The pump nozzles are structurally very successful.00:14:52
Their wear develops in much the same way as with Common Rail injectors.00:14:57
The only thing is that these injectors cannot be checked in the usual way for fuel draining.00:15:03
But you can check the injection parameters and engine operating parameters for characteristic groups of parameters during diagnosis.00:15:10
Cylinder idle correction parameters, solenoid valve needle locking time, cyclic feed volume ...00:15:17
All these parameters will give a complete picture of the condition of the nozzles, as well as the airing of the fuel system.00:15:24
The only thing with this diagnosis is the compression in the cylinders should be within the tolerance.00:15:31
The needle and valve seat wear out most often.00:15:34
In this case, the nozzle will not generate the required fuel pressure due to the fact that it will be squeezed out of the high pressure chamber.00:15:42
Also, the nozzle can be aired due to the fact that the gases in the cylinder will press on the needle due to insufficient fuel pressure.00:15:53
A nozzle pump with a worn-out spray gun and little pollution can be repaired.00:15:57
But if the control needle or electro-magnet is out of order, then the nozzle must be changed.00:16:05
The best pump nozzles, of course, in AutoStrong-M00:16:08
The nozzle pump must be installed on new seals.00:16:11
It is important to ensure that there is no production in the cylinder head.00:16:14
Also, after installing the nozzles, it is necessary to adjust the pre-tension.00:16:19
The tension here is adjusted using a screw and nut.00:16:23
As we have said, fuel is supplied to the pump nozzles from the ramp, which is located in the cylinder head itself.00:16:29
Please note that there are no fuel supply and return nozzles on the pump nozzles.00:16:34
The fact is that with this design, holes are used in the cylinder head and in the body of the pump nozzle itself.00:16:41
Above is the fuel return channel, below is the fuel supply channel.00:16:44
Moreover, with this design, excess fuel is returned through two channels.00:16:49
It enters the booster pump through the fuel return channel, and returns to the fuel rail through the fuel supply channel.00:16:58
The nozzle pump in the cylinder head is sealed with two o-rings.00:17:02
Naturally, if the rings wear out and lose their elasticity, then the fuel begins to mix with engine oil.00:17:10
To eliminate this problem, it is necessary to get the pump nozzles and change the o-rings.00:17:16
And now we will tell you about the trouble, because of which, long ago, the cylinder heads were changed, and now repair bushings are just installed00:17:25
The 1.9 TDI engine injector pump starts to hang out due to unsuccessful mounting.00:17:30
Because of this, they wipe the surface of the cylinder head in their nests.00:17:34
This production always occurs on the one hand - on the opposite side of the fastening of the pump injector by a latch.00:17:41
So, here we see the development.00:17:43
And also we see the output in the cylinder head in the nozzle socket.00:17:47
Again, because of this problem, fuel enters the engine oil, then the engine starts poorly due to air in the fuel system.00:17:55
But there is already a method of repairing pump injector sockets.00:18:01
Steel bushings are driven there and then the pump nozzles are installed.00:18:21
The cylinder head of this engine must be sent for repair, and the camshaft is just in perfect condition.00:18:39
On this side, the cylinder head is in good condition.00:18:42
With the cylinder head of the 1.9 TDI engine, no more problems happen.00:18:46
This motor is not commercial, it acted as a teaching tool.00:18:52
He got water into it and he got a blade in general with engine blocks with a pump with pump nozzles, nothing happens; they have a good resource and they are not in demand.00:19:11
On most motors with pump nozzles for transverse installation, an excellent reliable oil pump with a chain drive is used.00:19:19
On all motors with pump nozzles, the nightmare design of the drive of the oil pump with the hexagon from the balancing shafts is used for the longitudinal installation of the installation.00:19:32
This is a nightmare design that we have already talked about.00:19:36
Be sure to watch this video.00:19:38
In fact, today we have told absolutely everything about the malfunctions and characteristic features of engines with pump nozzles.00:19:46
There are no more problems with this engine. Therefore, we disassemble further.00:20:19
On the main liners we see the wear and tear characteristic of old oil.00:20:24
There are furrows and scuffs.00:20:27
If we talk about pistons, then we see oil deposits on the pistons.00:20:33
Because of which? Due to the fact that the scraper rings are coked.00:20:39
These rings are in good condition.00:20:50
And the crankshaft was kept in good condition.00:20:54
Well, a complete tour of the motors with pump nozzles and our disassembly are over.00:21:01
Well, in principle, these are good motors.00:21:03
But excuse me, 1.9 TDI did not make it into our top 10 diesel engine rating.00:21:07
