1.1. Gasoline Engine Consumption

Try these first

1. 1.

   What is the standard fuel consumption rate for gasoline engines?

   Hint

   Remember the values provided for gasoline engines.

2. 2.

   What factor must be adjusted when using theoretical values in real-world conditions?

   Hint

   Think about how these conditions affect performance.

3. 3.

   What is the standard fuel consumption of a gasoline engine?

   • 0.06 gallons/hp/hr
   • 0.04 gallons/hp/hr
   • 0.10 gallons/hp/hr

   Hint

   This is found in the section addressing consumption rates.

4. 4.

   Are fuel consumption rates impacted by machine operating conditions?

   • True
   • False

   Hint

   Think about the relationship between theory and real-world application.

5. 5.

   A highway truck rated at 300 horsepower operates with a fuel consumption factor of 0.06 gallons/hp/hr. If the truck operates under unfavorable conditions decreasing efficiency by 20%, calculate its effective fuel consumption rate.

   Hint

   Calculate the new consumption after applying the efficiency reduction.

6. 6.

   A machine's operational time lasts 2 hours with a load factor of 0.5 and a standard fuel consumption of 0.04 gallons/hp/hr for a 400 horsepower engine. Calculate the total fuel consumed during this period.

   Hint

   Adjust consumption based on operating factors and total hours of operation.
