4 cards from this section. Quick, good the night before a test.
What is the theoretical fuel consumption rate for a gasoline engine in gallons per horsepower hour?
Look for the standard value stated in the section.
What do you multiply to estimate hourly fuel cost?
Think about the components needed for this calculation.
What is the fuel consumption rate for diesel engines in standard conditions?
Refer back to the section discussing fuel consumption rates for engines.
True or False: The lubricating oil cost is invariant to the working conditions of the engine.
Think about the factors that influence oil wear and change intervals.
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?
Use the given rates to calculate both daily consumption and cost.
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.
Remember to include all movement costs when planning your project budget.
