1.2. Impact of Altitude on Combustion Process

Try these first

1. 1.

   What happens to atmospheric pressure as altitude increases?

   Hint

   Think about how air feels thinner at higher altitudes.

2. 2.

   Define fuel-air ratio.

   Hint

   What do we need to burn fuel efficiently?

3. 3.

   True or False: Combustion efficiency increases with altitude.

   • True
   • False

   Hint

   Think about how less oxygen affects combustion.

4. 4.

   What device can help maintain engine performance at high altitudes?

   • Carburetor
   • Turbocharger
   • Oil filter

   Hint

   What do you use to enhance air intake?

5. 5.

   Analyze a hypothetical internal combustion engine operating with 350 hp at sea level. What performance metrics can be expected if used at 10,000 feet elevation? Incorporate ambient pressure data in your analysis.

   Hint

   Consider how many feet above sea level affects air pressure.

6. 6.

   Create a detailed checklist for engineers to maintain combustion efficiency in machinery utilized at high altitudes, accounting for air composition, machinery type, and modifications.

   Hint

   Think of what you would check before taking off in an airplane?
