1.3. Turbochargers and Superchargers

Try these first

1. 1.

   What happens to atmospheric pressure as altitude increases?

   Hint

   Remember how air density changes at higher elevations.

2. 2.

   Name one device that can help compensate for the loss of efficiency in engines at higher altitudes.

   Hint

   Think about how air is compressed.

3. 3.

   What is the primary function of a turbocharger?

   • To inject fuel
   • To compress air
   • To expel exhaust

   Hint

   Think about the role of air in combustion.

4. 4.

   True or False: Superchargers are driven by exhaust gases.

   • True
   • False

   Hint

   Consider the method of power source.

5. 5.

   Consider an excavator operating at 10,000 feet without a turbocharger. Discuss the expected drop in efficiency and the implications for a construction project.

   Hint

   Think about how air density affects combustion.

6. 6.

   Evaluate a performance chart for a particular machine and determine how maximum power changes with different gear settings at various altitudes.

   Hint

   See how different settings might interact with the machine's capacity.
