1 Engine Conversion from Combustion to Compressed Air

2  Ordinary gasoline combustion engine converted to run on compressed air  Drivable, proof-of-concept car ◦ 5-10 minutes ◦ 10-15 mph  Three groups: engine modification, vehicle integration, testing and theory

3  Four stroke engine vs. two stroke engine  Golf cart, go-kart, building a chassis, mini Baja

4 Chose to modify the timing by CNC machining cam lobes. Norfolk Machine Shop

5 1. Remove Timing Case – 5 bolts 2. Place camshaft – line up timing mark 3. Remove old gasket material, and place new gasket 4. Re-attach Timing Case 5. Check all plugs are sealed 6. Add oil 7. Attach intake manifold Engine Assembly

6  Engine running backwards  Intake valve being blown open  Low airflow

7  Intake Adapter  Tanks  Ball valve (Throttle)  5/16” Line  Original design too restrictive  Met basic flow requirements after post-install modifications

8  Relatively Light Weight  Available Locally (Low Lead Time)  Price  High Pressure  Common Regulator  Easy Filling  Low Price For Used

9  Available at ODU motorsports lab.  Consulted with Dr. Ash about use.  Crank shaft was too large so adapter was machined to allow for use with Baja engine.

10  Dyno run #1  0.1 horsepower at 600 rpm  Dyno run #2  0.2 horsepower at 950 rpm
