2.1. Understanding Performance Charts

Try these first

1. 1.

   What happens to air density at higher altitudes?

   Hint

   Think about how this affects breathing.

2. 2.

   What is a turbocharger?

   Hint

   It helps engines perform better at high altitude.

3. 3.

   What is the main effect of altitude on engine performance?

   • Increases horsepower
   • Decreases air density
   • Improves fuel efficiency

   Hint

   Think about how the air feels when you climb a mountain.

4. 4.

   True or False: Performance charts can help predict the speed of machinery based on resistance.

   • True
   • False

   Hint

   Consider how graphs help convey information visually.

5. 5.

   You have a bulldozer operating at a site one mile above sea level. Explain how you would determine if an increase in machinery is needed due to altitude.

   Hint

   Consider how altitude affects engine specifications and rimpull.

6. 6.

   Given a scenario to operate a loader at 10,000 feet, what calculations and adjustments might you need to make?

   Hint

   Think about the equipment adjustments necessary at differing elevations.
