Specific Fuel Consumption
Specific Fuel Consumption
(OP)
The senior engineer at my company uses the following estimated constants to calculate the amount of fuel used by an engine.
.0.378 lbs/hr-h
0.282 lbs/kw-h
I have been using the data from the specification sheets for example from the Cat C18 engine and when I try to get this constant I am getting numbers closer to 0.7 lbs/kw-h. Does anyone else use these constants to estimate engine fuel consumption?

gravity having an LHV of 42 780 kJ/kg (18,390 Btu/lb)
when used at 29º C (85º F) and weighing 838.9 g/liter
(7.001 lbs/U.S. gal.)
RE: Specific Fuel Consumption
please clarify/confirm the units of measurement . . .
.0.378 lbs/hr-h (i'm thinking lbs/hp-hr)
0.282 lbs/kw-h

The original poster doesn't ask a question - I see only a statement and not a question. My only statement in return is that the statement that was originally made, is probably wrong, unless we are missing a critical piece of information - like what type of engine we are talking about here.
RE: Specific Fuel Consumption
yes, there is a question asked (a "yes/no" question) - please read the last sentence. agree in that clarification is needed.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Thanks again for your help :)
