|BENEFITS & ADVANTAGES||7|
· Correct Engine Diagnosis.
It is not possible to correctly diagnose the condition and performance of the injectors while they are on the car. A great deal of money and many hours, are spent trying to solve engine related problems that could be caused by poor injector performance.
· Emission Control & Reduction.
Correct fuel atomization is a critical factor in the requirement for complete combustion and minimum pollution. Without testing and servicing the injectors it is impossible to guarantee the minimum pollution.
· Restored & Increased Performance.
Test have shown that poor injector performance will be reflected in the cars overall performance. Servicing injectors could restore the cars lost performance.
· Reduced Warranty Claims.
With ASNU, Vehicle dealerships will be able to correctly confirm or reject injector warranty claims.
· Improved Fuel Economy.
Serviced injectors will produce maximum efficiency and minimum wastage of fuel. Saving on fuel over a 12-month period could far out way the cost of an ASNU injector service.
· Long Term Protection.
Lacquering of inlet valves, Bore wear, Lambda lacquering or failure, Catalyst clogging or failure.
Poor fuel atomization by the injectors can cause these problems, if you change the component without solving the cause of the problem, it will return.
· Satisfied Customers.
customer now expects the best from his car and his garage, ASNU ensures
that the customers engine repair/service bills are kept to a minimum and
quality of servicing to a maximum.
|FUEL SPRAY MANAGEMENT||8|
Spray Pattern has two major functions;
To distribute the fuel evenly to a specific point.
To atomize the fuel evenly at that specific point.
the event that the distribution or atomisation should change, the mixture
in the combustion chamber will also change, resulting in idling,
performance, economy and emission problems.
On simultaneous injection systems, the spray was regarded as important, on sequential injection systems, the spray pattern performance is critical to the correct running of the engine and the function of the emission control components.
|ASNU and Emmisions||9|
to the increase in public and Government
demand to reduce exhaust emissions, the computerized fuel injection
system is now fitted as
standard on all new petrol
vehicles produced and sold in Europe.
The testing of emissions is now standard in many counties and due to a
World Wide demand to reduce exhaust pollution, the allowance of exhaust
emissions will be
reduced again by the year 2000.
performance, accuracy and reliability of the components on the injection
system that control the emissions, are not just important, they are
critical. The fuel injector is now one of the most important
component in the control and reduction of these emissions.
the injector is a variable component, it is very difficult to correctly
and accurately measure
its performance and tolerances whilst on the engine, unlike other engine
are easily measured due to their fixed values.
cost involved in testing and servicing injectors is a fraction of the long
term costs in time -
Inlet valve lacquering and damage,
failure and replacement,
Exhaust failure and replacement,
Emissions is based on maximum engine efficiency.
efficiency is measured by correct cylinder combustion.
cylinder combustion is is reliant on correct Air/Fuel ratio, known as
Stoichiometric = 14:1.
14 parts Air to 1 part fuel, the fuel is the critical factor in the
The fuel is supplied by the individual injector valves, which are required to deliver an exact amount of fuel, in a specific form, to a specified point.

must be working correctly.
present, not one vehicle manufacturer recommends testing and servicing
injectors as part of a service schedule.

Do you have Injector Problems?
We never have injector problems!
As a FIS, you would obviously need to know what the injectors are doing,
how much fuel is being delivered? Are the spray jets correct? All things
you would have checked with a carburettor engine, so how do you
test injectors for flow rates, spray distribution and atomisation and for
What equipment do you use for testing these injector functions?
a workshop is asked about injector problems, most of the time the answer
we receive is “we don’t know if we have injector problems, we can’t
test then properly.
problem is, neither the Vehicle Manufacturers and very few of the
government run Motor Vehicle Training Colleges, train the technicians on
the functions and operations of the electronic injector valve.

facts on fuel injector valves
Injectors are now fitted as standard on all vehicles
produced and sold in Europe.
There is no equipment currently available that will enable the
technician to accurately analyse the condition of the injectors while they
are on the car.
It is impossible for the technician, to correctly and accurately
diagnose faults on a fuel injection
It is impossible for the technician to adjust the engine correctly,
if it has poor injector performance.
Lacquering of inlet valves, excessive bore wear, carboning of
Lambda sensors, clogging of Catalyst exhausts, could all be a result of
poor injector performance.
The injector valves are now one of the major components in the
controlling and reduction of exhaust emissions. How do you reduce
emissions on closed loop systems?
A reduction in the Fuel Droplet size will improve fuel economy,
increase performance and reduce exhaust pollution.
