semester goals
Semester Goals
  • Build Mounting System
  • Test using both Nitromethane and Hydrogen
  • Modify as needed and re-test
  • Make Recommendations and Proposals for further study and design
our engine
Our Engine

O.S. FS 70-II Surpass 4-Stroke Engine

mounting system
Mounting System
  • In order to Successfully Test the engine it needs to be securely mounted
  • We tried to test it by clamping the engine down, but this has proven un-successful.
mounting system5
Mounting System
  • Currently in the Process of Constructing a more rigid mount for our engine
lubrication
Lubrication
  • Oil will be provided through an access hole and closely monitored during and after each run
  • Currently Researching the use of a Graphite Lubricant for the Rocker Arms
fuel delivery system
Fuel Delivery System

Initial Setup Proposed from last Semester’s Design Report

- Use the Carburetor

fuel delivery system9
Fuel Delivery System
  • If time permits, a makeshift direct injection mechanism (non-electric) will be designed and implemented.
  • This will consist of a pressurized hydrogen storage tank connected to a check valve, which is connected to the chamber through tubing with a diameter smaller than the quenching distance of hydrogen.

Fuel Delivery System
  • A check valve will be used to allow flow into the cylinder during the compression stroke to eliminate backfire and improve volumetric efficiency.
