2.2. Impact of Working Conditions on Fuel Consumption

Try these first

1. 1.

   What is the standard fuel consumption rate for gasoline engines?

   Hint

   Recall the values discussed for gasoline engines.

2. 2.

   Which factor indicates the machine's working efficiency?

   Hint

   Think about how long the machine operates within a period.

3. 3.

   What is the standard fuel consumption for diesel engines?

   • 0.06 gallons
   • 0.04 gallons
   • 0.15 gallons

   Hint

   Remember the numbers discussed regarding diesel engines.

4. 4.

   True or False: Liquid fuel consumption rates are the same in all working conditions.

   • True
   • False

   Hint

   Consider how different work environments affect machinery efficiency.

5. 5.

   A construction project requires estimating fuel costs for a fleet of loaders. If each loader consumes 0.12 gallons per horsepower-hour and operates at 150 horsepower for 5 hours, and the local fuel cost is 70 rupees per liter, calculate the total fuel cost for 3 loaders.

   Hint

   Ensure to convert gallons to liters before calculating total cost.

6. 6.

   During a project, a loader has to work on alternating road conditions. If the consumption increases by 25% on poor roads, what is the new fuel rate per horsepower-hour if the standard is 0.12 gallons?

   Hint

   Think about how to calculate percentage increase.
