Bjp Race has an ASNU Injector testing and service machine. With this machine you can controll, flowtest and ultrasonic wash and service most of the injectors, Top-fed, Side-fed, Mechanical and even GDI injectors.

Injector Control: 130 SEK / pcs

Full Service: 260kr / pc

GDI Injector (Direct Injection)

Injector Control: SEK 200 / pcs

Full Service: 350kr / pc

Prices incl VAT.

Note the minimum charge amount 500 SEK.

The Injector is sent back for collections / postal advances. So you pay for the job and the shipping back when you pick up the Injectors at your local delivery point.

How long does it take to get the Injecotrs back? 

At the moment (Summer 2021) we do test / service and send back within 1-2 weeks. If you are in a hurry please email: info@bjprace.se and ask how we are located.

1. Injector control:

First, the Injector is checked externally for any damage, bad o-rings, etc.

Then the resistance and inductance of the Injector are tested. So they hold the same resistance as from the factory and that the inductance does not vary between the diffusers.

A leak test is done. Fuel pressure is applied to the top of the Injector and controlled so that it holds 100% tight when closed.

Spray image is checked. Both static (fully open) but above all dynamic at a number of different opening hours. Check if the spray image is still like the factory or if it has become weak or oblique, poor atomization that can cause droplets or otherwise poor spray image.

The flow is dynamically controlled and written on the protocol so you can see the difference between the Injecotrs.

The flow is also controlled statically. So you can see the maximum flow of the Injector.

Should something be wrong, the customer is contacted if service is to be done on the Injectors or if it should be returned as they are with the protocol.

The Injecotrs are returned marked with numbers and you can then see on the accompanying protocol how much each individual Injector flows.

2. Full service (tests, ultrasonic washing and new filters and o-rings included)

First, the Injector is checked externally for any damage and cleaned externally.

Then the resistance and inductance of the Injector are tested. So they hold the same resistance as from the factory and that the inductance does not vary between the diffusers.

A leak test is done. Fuel pressure is applied to the top of the Injector and controlled so that it holds 100% tight when closed.

Spray image is checked. Both static (fully open) but above all dynamic at a number of different opening hours. Check if the spray image is still like the factory or if it has become weak or oblique, poor atomization that can cause droplets or otherwise poor spray image.

The flow is dynamically controlled and written to the protocol so you can see if any Injector has lost in the flow and see the difference between the Injectors.

Then o-rings and the internal filter are removed.

The diffusers are placed in ultrasonic washing, and in the meantime are pulsed with various short and long opening times so that they are cleaned internally.

After washing, new o-rings and filters are mounted in the diffusers.

Then all tests are performed again before washing and everything is noted on the protocol.

The flow is also controlled statically. So you can see the maximum flow of the Injector.

You can see if and how many % the flow increased after washing if it was that the Injector was more or less clogged.

The Injector is delivered back marked with numbers and you can then see on the accompanying protocol how each spreader is feeling. Old o-rings and filters are also sent back.

Should there be any Injector that cannot be saved with ultrasonic washing, the customer should be contacted about any solution about new / new Inejcotr that can be matched together.

We carry out tests and service on most of the most commonly used top-feed injectors and side-feed injectors. Also most GDI injectors, also Piezo injectors. If you are unsure if we can test your injector you can contact us through email: info@bjprace.se or phone 0582-23070 and we will return with whether we can test your injector or not.

injectors can be sent to:

BJP Race AB

Harkranketorp 103

69493 Östansjö

Include contact information with phone numbers and be sure to pack carefully.

Also write what job you need: Only tests. Test (and service if required) or full service.

To get the injectors back as quickly as possible send them with DHL packages, Postnord Company packages or in padded letter with postage so it comes directly to us.

If you send by mail parcel, recommended, DHL service point or similar that we have to go and retrieve it can take up to 14 days extra as we do not have time to go to the post every day.

NOTE if you send DHL Service Points. Send to Frendo Ingo Hallsberg or Matöppet Åsbro. Do not send to Sojas Vretstorp then a fee of 500 SEK will be added!

NOTE We do not work on Diesel injecotrs!
 

Leak test of Injectors 30 seconds	No leak
Inductance test	The injector spray image is tested at different injector times. To simulate opening hours from idle to full throttle.
	O-rings and filters are removed before ultrasonic washing.
Ultrasonic wash.	Precision injector ready for service. These are Delphi injector with Precision decals and matched together by Precision.

Protocols included with the injector after testing or service.	We can test many different variants of injectors. Here Mercedes injector with unusual contacts and pins.
Cleaning in progress.	injector bench with several fuel rails for different types of injectors and tools for servicing injector. The machine can be controlled via the built-in display or via computer.

A Bosch EV1 injector that has a poor spray image.

Injector with widely varying flow. If there is such a big difference, it is hardly enough to have them cleaned up again.

 Vi kan testa de flesta olika typer av spridare för bensin eller gas. Här är exempel på några vi klarar att testa utan problem.

Spridare vi inte jobbar med: Diesel spridare av någon form. E-TEC 2-takts spridare. TBI spridare av den typ som på bilden ovan.
