1.3. Adjusting Fuel Consumption for Project Conditions

Try these first

1. 1.

   What is the fuel consumption rate for gasoline engines under standard conditions?

   Hint

   Think about typical values for gasoline engines.

2. 2.

   Define 'Operating Factor'.

   Hint

   Consider how we assess machine effectiveness during operation.

3. 3.

   What is the standard fuel consumption rate for diesel engines?

   • 0.06 gallons
   • 0.04 gallons
   • 0.02 gallons

   Hint

   Refer back to the consumption values from the text.

4. 4.

   True or False: The operating factor is derived solely from the time factor.

   • True
   • False

   Hint

   Consider how these factors interact in real operations.

5. 5.

   If a gasoline engine typically consumes 0.06 gallons per horsepower hour, what will be the cost of operating a 300 horsepower engine for 10 hours at a fuel price of 3 dollars per gallon?

   Hint

   Think about how many gallons a 300 horsepower engine consumes over 10 hours and multiply by the cost.

6. 6.

   You manage a site with trucks and loaders. If your trucks consume 15% less fuel than loaders under identical conditions, calculate the adjusted consumption for a situation where a loader uses 0.04 gallons.

   Hint

   You need to determine the percentage adjustment to find the truck's consumption.
