Injector Cleaning for all Fuel Injected Cars

Consider This

The problem of clogged injectors is caused by the combination of our use of fossil fuels with the very fine tolerances that exist in Electronic Fuel Injector systems. As we burn organic fuels in our engine and these fuels do not burn "clean", injectors become blocked. Considering these facts with the reality that the injector's operation is measured in milliseconds (thereby multiplying the effect of the minutest discrepancy many times in a second), the need for very clean pintles, director discs, seats, etc in the injectors becomes extremely significant.

Even delivery across all injectors and a good atomised spray pattern after cleaning is essential for smooth, economical performance. Some Benefits Include:
· Improved performance giving you what you paid for in your EFI vehicle.
· Improved economy. You will use less fuel.
· Improved engine efficiency.
· Saves you money.
· Better for the environment.
· Well-atomised fuel burns more evenly and readily than dripping, un-atomised, fuel in your combustion chamber.
· Move you closer to perfect combustion.

We at Mildren Race Engineering believe that the only way to do the above is to:
1. Remove the injectors from the vehicle.
2. Test and record results for all injectors : Leakdown, Atomisation, Timed open flow, Timed pulsed flow.
3. Ultrasonically clean the injectors (employing effective safe and environmentally friendly solvents).
4. Backflush the injectors at operating pressure.
5. Repeat the tests at point 2. above, to verify the effectiveness of the entire operation.
6. Re-install or return clean and properly operating injectors for the owner.
7. Provide the owner with a meaningful and accurate report, together with an explanation of the report.

If the injectors are not removed from the engine and examined properly before and after servicing, there is no way for the professional to be absolutely sure that each and every injector is delivering a well-atomised spray of accurately metered fuel to the combustion chamber.

Diagnostics on your car

Recently one our good clients brought in his Mazda RX7 series 5 turbo with an engine running problem.
The engine would not idle properly, was losing power, and was not driving as smoothly as it normally would. We proceeded to check over the car and look for any obvious problems, which may cause the symptom. Upon compression testing the engine, we found the compression across the six compression strokes to be quite uneven.
This, for those who aren't familiar with this problem, means something is not quite right inside the engine. The only way to verify the exact problem is to remove the engine from the car, disassemble the engine and look for something broken or deteriorated in condition.
We found with this particular engine, no broken parts, but un-usual carbon build up on seal's, which did not move as freely as they should. This is curious - how did this come about?
We tested the four injectors for flow - and there we found the problem! We recorded flow discrepancies between injectors of up to 9.5%.
This means that some of the injectors were delivering up to 9.5% more fuel than others.
The effect of such a discrepancy would no doubt have led to bad fuel economy and unstable idle.
The effect inside the engine would have been some of the engine running rich in mixture and some of the engine running lean - in other words un-even fuel delivery!

Now, what can you learn from someone else's experience? And, what's the difference between this particular car and your own? This car in our story is a regularly maintained, electronically controlled, fuel injected vehicle, just over 10 years old and unmodified.
