This is diesel equipment which we now call early diesel.

It generally has little or no electronic control

and has been replaced in passenger cars by the common rail system.

Bosch and Lucas injectors

Also Bosch and Lucas type rotary injectors Diesel is injected into highly compressed, hot air

Hence Diesel engines of any type work because diesel fuel is injected into a cylinder of highly compressed air.

Because the air is compressed it is very hot.

As a result Fuel ignites forcing the piston down into the cylinder and turning the crankshaft.

Diesel fuel has to be atomised, turned to mist or microscopic droplets.

Consequently the injectors are designed to make this happen.

Most cases the problem is that the fuel is irregularly sprayed. In the engine appears knocking and in this case it burns more unsprayed fuel.

Other problems arise if the injection jet is installed incorrectly.

If the injection valves are directed at the cylinder wall, oil firm burns out and so-called “rusty stains” appear.

Moreover, this can cause overheating that leads to piston burning-out.

If there are problems with combustion, the driver hears strange noises in the engine.

This is the reason to check the engine and fuel injection valves particularly.

In old cars it is possible to check them without any assistance.

Modern cars have a lot of electronics and it will be quite difficult do service them.

THE REASONS OF INJECTOR MALFUNCTIONS

The most frequent malfunction of Fuel Injectors is clogging.

During operation, the components are exposed to high temperatures.

Which results in carbonizing the holes of the nozzles with the resins contained in the fuel.

This may also be caused by poor tightness of the locking cones.

Carbon deposition 5 µm thick results in reducing the flow rate of the nozzle by 25%.

When poor quality gasoline containing fine solid particles is used, the fine mesh filter intended for cleaning fuel gets clogged.

Furthermore the size of the metering orifice and the shape of the injected fuel spray change.

Premature wear of injectors and jamming of the needles in the guides may be caused by poor quality of the components.

Needles also get jammed due to insufficient cleaning of the fuel, or due to incorrect installation of the components.

Mechanical damage of the injectors is caused by uncareful repair or by incompetence of the specialist.

REPLACING A FUEL INJECTORS
If the injectors are cleaned on a regular basis, their service life may reach 200,000 kilometers of mileage.

To replace the component, first relieve pressure in the fuel rail.

Then remove the connecting pipe going from the air filter,

The IAC (idle air control) valve wiring harness, injectors wiring harnesses, and the throttle position sensor wiring harness.

Next, disconnect the hose from the fuel pressure regulator, and unscrew the pipes that supply fuel to the fuel rail.

After that, unscrew the bolts that hold the rail in place, and remove it.

Disconnect brackets of the injector and extract it; replace a faulty component.

To install a new component, assemble the unit in the reverse order.

This is a harder sign to look out for because if it increases very gradually over time it can be very hard for the driver to tell the difference between how it used to run and now.

But what can be summarised as ‘rough running’ exactly?

The customer can look out for a deeper, gravely engine sound, engine chugging, the whole vehicle might have a slight shake or vibration.

One of the best windows of opportunity for the driver to assess how the vehicle behaves is on a cold start.

If the engine is hard to start it can be a sign that the fuel delivery is wrong or the timing is poor.

Unstable RPM can also be a sign of an engine struggling on with incorrect fuel supply.

A significant drop in fuel efficiency can often go hand in hand with rough running

As a result, the high pressure delivery is beginning to fail and can be an easier signal for your customer to monitor.

This contamination can not only lead to poor performing injectors,

but can lead to broken injector nozzles like the one pictured here.

So what happens when someone has an injector failure like this?

They most often replace just the one bad injector.

Sometimes they replace the whole set.

These old injectors are then sent in to be rebuilt as cores.

Now we know if one injector has failed from debris being run through it,

the rest of the injectors are probably damaged too.

An injector builder that is less than reputable or inexperienced.

may pass these functioning injectors through the rebuild process because they test ok after cleaning.

Furthermore you get a rebuilt injector usually for a budget price.

Therefore these injectors will not last.

The market is flooded with them.

Finally you will be installing an injector that is pretty much half or more worn out.
