Design of an Optically Accessible Internal
Combustion Hydrogen Engine

• Martin Borja
• Advised by Professor Brad Bruno
• Fall 2004

2
OBJECTIVE

• Design an optically accessible IC engine suitable
  for use with laser diagnostic techniques, and
  Hydrogen fueled combustion.

3
Motivation

• Real combustion in an IC engine is to complex
  to solve analytically
• Time varying
• Turbulent
• 3-D
• Reacting
• Commonly used for Research/Development tool
• Will be useful as a teaching tool at Union
• Hydrogen IC Research
• No optical work on Hydrogen IC engines yet

Feasible Materials for Cylinder

• Materials - Sapphire
• - Deep UV grade Quartz
• - UV Grade Glass
• Materials must resist the high internal pressure
• and temperature.

7
Done so far

• Extensive literature review
• Various SAE papers
• Site Visit (PSU)
• Detailed procedure for head removal
• Research Suitable Materials and Providers
• Concept Selection Criteria

8
Done so far

• Selected Material
• UV Transmitting Vycor 7913 from Corning Inc.
• Constructed preliminary model of transparent
  cylinder on COSMOS using the material properties
  of the selected glass
• Conducted a Transient Thermal Stress Analysis
  using COSMOS to test material feasibility as well
  as the basic design (wall thickness)

Currently..

• Working on Geo Force Study with Prof. Bucinell
• Obtain accurate FOS and stress results on glass
  cylinder to ensure that it will hold under the
  applied thermal and static loads
• Designing and fabricating the necessary tools to
  lift the engines head up (Machine Shop)
• Timing pin
• Camshaft to TDC tool
• Sprocket Holding Tool

11
Next Steps

• Lift engines head up to obtain detailed setup
  information
• Finish Thermal Stress Analysis (Geo Force) .
  Prof Bucinell
• Start the actual design
