4 cards from this section. Quick, good the night before a test.
What is the standard fuel consumption rate for gasoline engines?
Think about standard operating conditions.
Name a factor that impacts fuel consumption rates.
Consider the operating conditions of the machine.
What is the standard fuel consumption for diesel engines?
Remember the values provided for diesel engines.
Is it important to adjust fuel consumption values based on project conditions?
Think about why standard conditions alone may not apply.
A gasoline engine has a theoretical consumption rate of 0.06 gallons/hour. A project requires adjustment due to poor load and time factors resulting in a load factor of 0.4 and a time factor of 0.5. Calculate the new consumption rate.
Multiply the base consumption by load and time factors.
An excavator operates at 300 horsepower with a fuel consumption factor of 0.25 gallons/hp hour. If its operating efficiency is 70% for 40 minutes per hour, calculate the hourly fuel consumption and cost if fuel is 70 rupees per liter.
Calculate using the horsepower, consumption rate, and then apply the cost.
