Question 1

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

  • 0.06 gallons per horsepower hour
  • 0.04 gallons per horsepower hour
  • 0.23 gallons per horsepower hour

💡 Hint: Refer back to the section discussing fuel consumption rates for engines.

Question 2

True or False: The lubricating oil cost is invariant to the working conditions of the engine.

  • True
  • False

💡 Hint: Think about the factors that influence oil wear and change intervals.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a construction project using a loader that operates under harsh conditions. The loader's performance typically drops fuel usage to 0.08 gallons per horsepower hour. If the loader runs 12 hours a day at 300 horsepower, what will be the daily fuel cost if diesel is priced at $4 per gallon?

💡 Hint: Use the given rates to calculate both daily consumption and cost.

Question 2

You have a project that temporarily requires shifting excavators between job sites three times over two weeks, costing $600 each time. If it takes two weeks, estimate the total mobilization cost for the project. Consider cost variations.

💡 Hint: Remember to include all movement costs when planning your project budget.
