3.1. Factors Influencing Fuel Cost Calculation

Try these first

1. 1.

   What is the standard fuel consumption rate for a gasoline engine?

   Hint

   Think back to the discussion about gasoline engines.

2. 2.

   Define 'standard conditions' in the context of engine operation.

   Hint

   Consider how fuel consumption is measured.

3. 3.

   What is the fuel consumption rate for diesel engines at standard conditions?

   • 0.06 gallons
   • 0.04 gallons
   • 0.03 gallons

   Hint

   Recall the specific rates we discussed for different engines.

4. 4.

   True or False: Fuel consumption rates are fixed and do not vary with project conditions.

   • True
   • False

   Hint

   Think about how adjustments are necessary based on the project.

5. 5.

   A bulldozer has a standard fuel consumption rate of 0.08 gallons per horsepower per hour. If it's rated at 600 horsepower and operates at full load 50% of the time over a 2-hour work session, calculate the total fuel used.

   Hint

   Break down the problem into parts: calculate hourly and then multiply by time.

6. 6.

   An excavator consumes 0.11 liters per horsepower hour. If it works at an operating factor of 0.65 for a project requiring 300 horsepower over 3 hours, what is the total fuel cost if the price of fuel is 50 rupees per liter?

   Hint

   Consider the steps: first find total fuel used, then multiply by cost.
