Injector Flow VS Fuel Pressure Calculator Fuel Pump Calculator General Conversions. 15psi (270kPa) “across the injector. Tables Injector Flow Rate, Min PW, Offset vs Volts vs VAC, & Short Pulse Adder. The term “across the injector” takes manifold pressure and fuel rail pressure into account, and is usually referred to as “delta pressure. However, doing it can get you the results you are looking for but you are just tricking the PCM into thinking the injectors are larger or smaller than they really are. In the past, we have used devices like the AFC, ICCU, etc for two reasons. Note on Injector Flowrate Measurement: when R0 is measured on an injector flow bench, P0 is actually the pressure difference across the injector: I have spent countless hours of research for my Siemens 60# injectors and have finally found data that works. If you have the stock injectors, running regular gasoline (not E85), then you need the stock settings. Marcin's spreadsheet is attached to this post (scroll down to bottom of post #1).

I am comparing this to the calculated flow method found on injector flow testing spreadsheets noted in many other posts. This is a calculated value based on flow per injector stroke converted back to cc/min flow assuming a 6000rpm pulse rate. Low impedance injectors are used on high Actual Injector Flow Rate. Includes tables in returnless and referenced return-style formats. Typical injector heights are 64mm, 53mm, and 38mm between o-ring centers. 35 g/sec (Only an 8% error) My table looks like this: Flow rate at new delta pressure = (flow rate at old pressure) x √(new pressure/old pressure) Example: What is the flow rate for an injector at 43. If you find a flow rate to be skewed from what your test results showed, it has to do with this. 5psi if it is rated at 60 lb/hr at 39. Had a look at the injector tables looks like 2008 or so L92 Gen IV type injector data modified for use with a Gen III controller.

The injector data given is based on manufacturer's published data and are given for the specific base fuel pressure listed. I need to test all of the other 7 injectors to see if this still seems a good method. IFR2 = IFR1*SQRT(P2/P1) > IFR2 = 40. Lb/hr (pounds per hour): The Imperial/American or ‘SAE’ unit of measurement used to describe the flow rate of Injector flow in cc/min. Any time your ACTUAL injector flow rate is greater than the maximum allowed flow rate in the PCM, you will likely need scaling. You can be sure that if the data for a Bosch injector is displayed in units other than g/min then the data has been converted mathematically or the information has been provided by private Use the flow rate (Bar) listed on this site as the “old” pressure, and the pressure you would like to know as the “New” pressure. Injector flow in cc/min. 7525 = 640 So instead of 570 cc/min that results from 100% E85, your injectors will actually flow like 640 cc/min injectors with a 75% E85/25% gas mix. 15psi?

Industry-Leading Technical Support. 88157463 24. 6 Aug 7, 2005 · I was noticing that when I put in some exact numbers into this table from an excel sheet (injector flow rate calculator sheet) and I saved the tune in EFI LIVE and then exited and came back and brought up the injector flow rate table (B4001) that the numbers were a little different from what I had put in. Tested results and Published results always vary. Looking at my tune under Injector control, I see Flow Rate, Limits, Offset and Pulse Corrections. Bosch Fuel Injectors, flow rates. For example: An injector that flows 330 cc @ 40 psi will flow 369 cc @ 50 psi. 96 gm/pulse - 2. Calculated Flow rate at the new pressure Major Injector manufacturers (eg. . 11440077 25. HP x BSFC/ # of Injectors x duty cycle = lb/hr per injector. Remember that if you are still running the in-tank regulator (no manifold referenced regulator at the rail), then the IFR table still needs to be able to model the so if I were to use the posted injector flow rate spreadsheet. 5psi OE fuel pressure, others, like many of the GM cars run 58psi (4 bar) fuel pressures – e. per hour) for each horsepower made. (N-Heptane) 260. 5psi delta = 60 * √(43. Your new injector flow rate will be calculated automatically. To find the flow rate of the injector, we can supply pressurized fuel at the inlet, apply voltage to the coil, and measure the amount of fuel that flows through the injector in a given period of time. 5 psi) and a maximum injector duty cycle (IDC) of 80%. 31273468 23. Thank you for the help. 5 psi / 3 bar 24. Be sure if using this data that your base fuel pressure is set to the listed fuel pressure otherwise the data will be inaccurate.
