Fuel Injector Calculations

[Ohio HD]

All of the calculations in the spreadsheet can be found on the web. I just wanted to have them all in one place.

You can use this to calculate the flow rates from one measure to another.

The estimated horsepower at the crankshaft can be calculated to the fuel usage / injector size required.

To my understanding most all fuel injector specifications are calculated at 43.5 PSI (3 BAR). The HD fuel system has a 58.0 PSI (4 BAR) rated fuel system. The calculations in the sheet are based on 43.5 PSI, but will also show the 58.0 PSI results.

A heads up, the rev04 sheet I loaded last night has some errors in the convert flow rates page for a couple of the values. Rigidthumber brought to my attention this morning. It was the L/min values (Liter Per Minute). I have a new rev05 to load, I believe it's ok. I looked it over and am asking Ridigthumper to review to see if I missed anything. More eyes are always better. Stay tuned.

Ok, we have that straightened out. We removed the L/Min calculation as it for one isn't really needed at all.

Se we have the updated version, it can be seen here interactively on the HTT site. Coyote set us up with some HTML code to allow interactive use of the application.
