Summary: Spec sheet

Solution:
Thanks for your Email message.  You have contacted Cummins, Inc. at our Customer Assistance Center located in Columbus, Indiana.  This is our worldwide headquarters and has been our home since Clessie Cummins founded the company February 3, 1919.

We are sorry but we do not hand out engine specification sheets.  We also make it a point not to publish any "maximum exhaust gas temperatures".

In marine applications, the only point on the power curve where the power required by the marine drive and accessories and the maximum power produced by the engine are the same is determined by the hull manufacturer when designing the boat and takes into account the marine gear ratio, hull curves at different waterlines, the propellor curve and accessories driven.

Unless you have the other information affecting the performance of your boat the engine power curve is not useful information.

We no longer make the #one brake specific fuel consumption curve public information.  Though accurate, these curves cannot be used to predict fuel consumption except at the point where the #one power curve crosses the power demand curve developed by the hull manufacturer.

The curve was badly misrepresented and misunderstood and therefore misleading to those that tried to use it to predict other than full power fuel condumption.

We thank you for your interest in Cummins products.  We occasionally misunderstand a question.  If our answer to your communication looks like we have misunderstood your e-mail please reply with further inquiry.

I called your marine assistance line to get the correct performance curve
spec sheet for my engines and was told I couldnt have it.  I need the data
to properly care for the engines and telling me I cant have it seems silly.
I need to know the max rated EGT.  I need to see max HP at different RPM.
My perspective is that everyone should have this data and, with it, there
would be far fewer engine failures due to overload.

I would like you to review this policy and get back to me. I like Cummins, I
love the service success Ive had with these engines, I even like the parts
prices but I do need the information to properly maintain them and I would
like to get it from you without extensive negotiation if at all possible.
Basically, I believe my request is reasonable and in Cummins best interest.
Could you get back to me on this? Thanks for your time,

                                                --jrh

P.S. Should you chose to release the sheet I'm after it's for this engine:
45828546 (build date 3/23/1999) -- CPL: 2205.
