Frequently Asked Questions
-
What does pound per horsepower-hour measure?
-
It measures fuel mass consumed per unit of power output over an hour, indicating engine efficiency with lower values showing better fuel use.
-
Why convert to gram per kilowatt-hour?
-
Converting allows comparing fuel efficiency using standardized SI units common in industrial and scientific applications.
-
Can this conversion be used for all engines?
-
Yes, but it is most suitable under steady-state conditions and may not reflect transient operating states.
Key Terminology
-
Pound per horsepower-hour
-
A unit measuring the mass of fuel in pounds consumed per one horsepower output over one hour, used to express engine fuel efficiency.
-
Gram per kilowatt-hour
-
A metric unit representing grams of fuel consumed to generate one kilowatt of power in one hour, indicating specific fuel consumption.
-
Brake Specific Fuel Consumption (BSFC)
-
A parameter quantifying fuel consumption per unit of engine power output, used to compare engine efficiency.
