Title: Motec Solution

1
Motec Solution

Changed injection time
Measured in degrees BTDC (before top dead centre)

Rath
2
Motec Interpreter

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

Rath
3
Testing

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

Water leak, tightened connector
Rath
4
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

Rath
5
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

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

Rath
9
Advantages of E85

Burns Cleaner Resulting in Cleaner Emissions
Renewable Energy Source
Less Dependence on Foreign Oil
Increase in Power
Health Impact

Rath
10
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

Rath
11
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)

Argonne National Lab Dynamometer

Texas Tech Future Truck was the first vehicle
used to test hydrogen system on the dynamometer
setup .
