Does not account for fuel composition or varying engine operating conditions.
Frequently Asked Questions
-
What does gram/horsepower (metric)/hour measure?
-
It measures the mass of fuel consumed in grams to produce one metric horsepower of power for one hour, reflecting specific fuel consumption.
-
Why convert gram/horsepower (metric)/hour to gram/kilowatt/hour?
-
Converting to gram/kilowatt/hour standardizes fuel consumption data to SI units, facilitating regulatory compliance and fuel efficiency comparisons.
-
Are there inaccuracies in this conversion?
-
Minor inaccuracies may arise due to different horsepower definitions, rounding, and assuming a fixed watt equivalent for metric horsepower.
Key Terminology
-
Brake Specific Fuel Consumption (BSFC)
-
A measurement of fuel efficiency indicating the mass of fuel consumed per unit of power output over time, expressed in units such as gram/kilowatt/hour or gram/horsepower/hour.
-
Metric Horsepower (PS)
-
A unit of power equal to 735.49875 watts, commonly used in engine performance measurements.
-
Gram/kilowatt/hour (g/kW·h)
-
A unit expressing the mass of fuel consumed per kilowatt hour of energy produced, used to quantify fuel efficiency.
