How much tension the spring provides on the pintle which is seated against the nozzle. We can reduce or increase this tension by adjusting the size of the shim that is underneath the spring.

Thicker shims mean more tension, thinner shims mean less tension. If we lower the pressure they open at we effectively advance the timing of the injector firing sequence, if we increase it we effectively retard the timing of the injector firing sequence. This is an important consideration when getting the injectors re-conditioned, especially if higher pressures are recommended by the shop performing the work for you.

Different cars are built around different injector opening pressures. As the pump ramps the pressure up to Crack pressure, the injector will fire. So it is very important to remember, there is more than one timing adjustment on this style of engine. Both must be set to compliment each other. You can have thicker shims in the injector to increase injection pressure which is good!

But you must advance the pump up to ensure it is being injected at the correct time. With turbocharged engines we have vastly different amounts of airflow on boost to what we have off boost. It does this through a pressure intake port in the top of it, which pushes an internal diaphragm containing the fuel pin down into the pump.

This increases the amount of fuel delivered depending on the boost pressure pushing down on it. Without the boost compensator tuning on a turbocharged engine would be very limited. Photos are for reference only.

Due to product being exchange. The short answer is NO. There is no benefit in doing this. It does not aid combustion at all. Turbo and Fuel Injection Australia. Injectors Nissan Exch. Injectors Toyota Exch. Tick Core Deposit box to add Core Deposit if requiring injectors sent to you first. SKU: B. Number stamped on the injector body will be B It can be hard to read the number on the injector.
