Internal Combustion Engine question

Click For Summary
SUMMARY

The discussion centers on the potential use of mono-crystal Alumina as a replacement for aluminum in internal combustion engines (ICE). Participants highlight that MC-Alumina possesses a higher density and greater strength compared to aluminum, making it a promising material for components in methanol or ethanol-based engines. However, the high manufacturing costs and the lack of existing research specifically on mono-crystal Alumina in engine applications are significant barriers. Historical references to Pratt & Whitney's experiments with single crystal turbine blades in the 1970s are also noted as relevant.

PREREQUISITES
  • Understanding of internal combustion engine components
  • Knowledge of materials science, specifically ceramics
  • Familiarity with manufacturing processes for advanced materials
  • Basic concepts of fuel types, particularly methanol and ethanol
NEXT STEPS
  • Research the properties and applications of mono-crystal Alumina in engineering
  • Explore the historical context of Pratt & Whitney's single crystal turbine blade technology
  • Investigate the use of ceramics in engine components, focusing on cylinder blocks and pistons
  • Examine the cost-benefit analysis of using advanced materials in internal combustion engines
USEFUL FOR

Engineers, materials scientists, and automotive researchers interested in innovative materials for internal combustion engines and those exploring alternatives to traditional aluminum components.

Just out of curiosity, as I am very amateur here, in ICE could mono-crystal Alumina replace aluminum and create a better engine? Aside from the high cost to manufacture.

I know MC-Alumina has a higher density than Al but is considerably stronger. This would be fantastic, I would think for a methanol/ethanol based engine.

You will find a lot of interesting information about this subject if you search on :

Ceramic + (any of) Engines / Cylinder blocks / Cylinder heads / Pistons / Cylinder liners / Valves

Correct, however I do not see any information based on mono crystal. The ceramics used are usually at most 99.8% Alumina. I am sure this is due to a few reasons. My sole focus is on purity (9n plus).
 
i think Pratt-Whitney experimented with single crystal aircraft engine turbine blades in 1970's.

Add that name to your literature search ?
