Motec solution l.jpg
Motec Solution

  • Changed injection time

  • Measured in degrees BTDC (before top dead centre)


Motec interpreter l.jpg
Motec Interpreter

  • Measure RPM, voltage, air pressure, and fuel actual pulse width


Testing l.jpg

  • Observed water leak while testing on dyno, coming from a fixture going into the engine

    • Tighten bolt on fixture

Water leak, tightened connector


Injection pump l.jpg
Injection Pump

  • Injects water directly to intake of motor

    • Allows engine to run cooler

    • Provides ability to inject more Hydrogen

      • Resulting in more power

  • Pump not working

    • No power being delivered


Power to injection pump l.jpg
Power to Injection Pump

  • Trace wire from pump

  • Connect to water pump circuit board on passenger side

    • Circuit connected to 12V battery

  • Connected brown wire (pump wire) with 12V relay

    • Pump energized

New Objectives- Challenge X

  • Moved to Challenge X for 1 Week

  • E-85

    • History

    • Advantages/Disadvantages

    • Integration into cars


History e 85 l.jpg
History E-85

  • E85 is an alcohol-based fuel containing 85 percent ethanol and 15 percent unleaded gasoline

  • EPA act of 1992

    • Alternative Fuel Vehicles

    • Flex Fuel Vehicles


Advantages of e85 l.jpg
Advantages of E85

  • Burns Cleaner – Resulting in Cleaner Emissions

  • Renewable Energy Source

  • Less Dependence on Foreign Oil

  • Increase in Power

  • Health Impact


Disadvantages of e85 l.jpg
Disadvantages of E85

  • At present, E85 Costs more than gasoline

  • Driving Ability of E85 is lower

    • Lower per gallon energy value

    • Takes more to drive same distance

    • Refueling more often

  • Availability

  • Absorbs water diluting the ethanol

  • Highly flammable and explosive compared with gasoline

    • Safety considerations


Integration into cars l.jpg
Integration into Cars

  • Since 1992 E85 vehicles have been developed

  • 3.5 million E85 vehicles are anticipated to be on the road by the end of model year 2004 – NEVC (National Ethanol Vehicle Coalition)

Test run 1 l.jpg
Test Run 1


  • Electrical Assist used on First “hill”

    • Battery Depleted

  • Hydrogen Only Rest of Run

    • Vehicle stopped running

  • Was not able to complete Test

Data Test 1


Test run 2 l.jpg
Test Run 2


  • Electrical Assist was used on Test Run 2

    • Battery Charged to 310V before test

  • Able to complete Test Run

    • However, Still had problems with vacuum and back flash
