5.1. Factors Affecting Lubricating Oil Requirements

Try these first

1. 1.

   What is the fuel consumption rate for a gasoline engine per horsepower hour?

   Hint

   Look for standard values provided for gasoline engines.

2. 2.

   List one factor that affects lubricating oil requirements.

   Hint

   Think about what could impact oil consumption.

3. 3.

   What is the typical fuel consumption for a diesel engine?

   • 0.06 gallons
   • 0.04 gallons
   • 0.15 liters

   Hint

   Recall the distinct consumption rates given for each engine type.

4. 4.

   True or False: Lubricating oil changes are always done every 100 hours.

   • True
   • False

   Hint

   Consider the impact of project conditions on maintenance schedules.

5. 5.

   A construction company operates a diesel engine with a power of 300 horsepower. The operational factor is found to be 0.5. Calculate the expected oil consumption in liters per hour using the formula. Assume the oil consumption factor is 0.0027 kg/hp and conversion factor is 0.89 kg/l.

   Hint

   Remember to convert kg to liters at the end!

6. 6.

   A specific model of a diesel engine uses 0.125 liters per horsepower per hour. If this model is rated at 500 horsepower and operates an average of 8 hours daily, what would be the total daily oil consumption in liters?

   Hint

   Follow the steps: establish the rate, multiply by power and time.
