Motec Solution • Changed injection time • Measured in degrees BTDC (before top dead centre) Rath
Motec Interpreter • Measure RPM, voltage, air pressure, and fuel actual pulse width Rath
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
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
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 Rath
Injection Pump Pump connected to 12V Rath
New Objectives- Challenge X • Moved to Challenge X for 1 Week • E-85 • History • Advantages/Disadvantages • Integration into cars Rath
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
Advantages of E85 • Burns Cleaner – Resulting in Cleaner Emissions • Renewable Energy Source • Less Dependence on Foreign Oil • Increase in Power • Health Impact Rath
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
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) Rath
