PLUG-IN HYBRID PRIUS
WHAT
Multi-phase project started as a senior design project in the Automotive and Manufacturing Engineering Technology Department (Fall 2006)
Modify a stock Toyota Prius Hybrid with the goals of demonstrating increased fuel economy coupled with flexible fuel (ethanol blended) capability without increasing tailpipe emissions
PLUG-IN HYBRID PRIUS
Specific Goals
Average fuel economy of 100 MPG
Operation on E-85 fuel
No negative impacts to drivability
No increases in stock vehicle emissions level (as measured based on drive cycle test measurements)
PLUG-IN HYBRID PRIUS
Enablers
100 MPG
–
Increased battery pack capacity through use of higher energy density chemistries and/or via increased pack size
–
Plug-In* capability to enable battery pack charging when the vehicle is not in use *Although energy gained from the “grid” is not free, its equivalent fuel cost can be relatively low and hence it can greatly improve average fuel economy.
PLUG-IN HYBRID PRIUS
Enablers
Flexible fuel capability
–
Materials compatibility testing
–
Consideration of fuel pump and injector capacity constraints
PLUG-IN HYBRID PRIUS
Enablers
Drivability
–
Placement of battery cells to distribute the increased mass within the frame and interior constraints
–
Design of enclosures and mounting to reduce relative movement between the vehicle and the added mass components
–
Close adherence to weight and balance constraints.
PLUG-IN HYBRID PRIUS
Enablers
No impact to drive cycle emissions
–
Increased usage of battery capacity over the drive cycle (allows electric only operation*)
–
Base-lining and emissions lab familiarization for repeatability
–
Extensive tailpipe emissions test and measurement *This becomes an optimization problem since other vehicle systems are effected during engine off conditions such as catalyst cooling, etc.
PLUG-IN HYBRID PRIUS
Vehicle Modifications
After baseline testing for fuel economy, emissions and drivability, the vehicle will be modified with a number of enhancements
The next few slides show the anticipated progression of modifications…
FLEXIBLE FUELED VEHICLES
Ability to Use ANY Blend of 0% to 85% Ethanol Larger Fuel Injectors Some Different Fuel System Materials Some Vehicles Use a Special Sensor Others Let the Computer “Learn” the Type of Fuel In-Line Fuel Sensor

E-85 HYBRID
2006 Toyota Prius
Insert flex-fuel kit to run on ethanol. Material compatibility testing will be done to see if ethanol corrodes or erodes the components of the fuel system, such as the fuel rail and fuel pump.
