CRDI engine at different fuel pressure
CRDI engine at different fuel pressure
(OP)
Hi,
I want to change the fuel pressure of CRDI engine and check the performance of it,how can i do it (is there any pressure valve that i can adjust)?

Very easy to blow things up by not knowing precisely what you are doing with such systems, though.

Nearly doubling the rail pressure, without making hardware changes, does not sound like a good thing to be doing. If the rail pressure was 900 bar in the original engine design, it is likely older-generation hardware that was not designed for higher pressure.
Do you know if the rail pressure is electronically regulated? If it is, you just have to change the setting in the ECU. But it is highly likely that such a large change is beyond the range of the original sensor and actuation hardware.

- Assuming you can dial up the pressure, what do you hope to gain? Lower particulate emissions?
If you're hoping for more power, wouldn't it be easier to change to injectors with larger orifices, and/or change injection timing+duration? I just can't see loading up the geartrain and the high pressure fuel system with a huge pressure increase as a viable option for "performance" (power) gains alone.

I am ready to select the injector and pump for the high pressures.
thank you for your comments :)
