The Turbodyne TurboPac™ for Automotive Applications
The TurboPac™ Air Induction System
The TurboPac™ Technology features three models for automotive applications;
TurboPac™ 1800 for Small-displacement gasoline engines used in hybrid vehicles
TurboPac™ 2100 for Mid-size gasoline powered vehicles over 1.5 liters
TurboPac™ 2400 for Large gasoline or diesel powered vehicles.
 The TurboPac™ is an electrically-powered air intake system that provides high-velocity air to internal combustion engines.
The TurboPac™ has three areas of performance and efficiency improvements at low engine RPMs:
1. Increases torque during the highest demand periods, and thus increases horsepower and acceleration.
2. Reduces fuel consumption (improves fuel mileage) in two different ways:
a.
for diesel powered vehicles, especially stop-and-go vehicles such as
city busses, waste hauling trucks and local delivery trucks, improves
horsepower and acceleration at the low-end of the RPM range and more
completely burns fuel in the engine, rather than exhausting (and
wasting) partially combusted fuel.
b. by increasing engine
horsepower, especially at low RPM, vehicles can be designed, or
re-powered with smaller displacement engines that are more
fuel-efficient for their driving cycle. This is particularly important
for hybrid vehicles which currently have a lower-limit of about 1 liter
in engine size. With a TurboPac™, we believe engines of 500 cc to 750 cc
could provide the same level of performance - thus reducing engine size
by 25% to 50%.
3. Reduces particulate hydrocarbon emissions (black
smoke pollution) from diesel engines that substantially reduce
pollutants and are certified for California emissions and EPA programs.
TurboPacs™ can be applied to engine applications to:
a) Reduce fuel costs;
b) Increase engine torque at low RPM;
c) Increase vehicle acceleration from standstill, for both turbocharged and non-turbocharged engines, and
d) Reduce emissions, especially particulate hydrocarbon emissions from diesel engines at low RPM and during acceleration
The TurboFlow™ for Automotive Applications
 The
increase in popularity of smaller displacement and alternative fuel
burning engines is creating challenges in the industry. As engine
design moves toward smaller and smaller displacement, the need for
significantly more air to achieve standard and high performance levels
of acceleration in normal vehicle operating conditions increases
exponentially. This can only be achieved through independently and
electrically controlled air induction. This represents a huge
opportunity for Turbodyne to enable independently controlled,
electrically powered air induction.
The Turbodyne TurboFlow™ air injection system uses an electric motor
instead of mechanical linkages to run an air compressor injecting air
into an engine system. Eliminating the direct mechanical coupling for a
super- or turbo-charger avoids engine power reduction (supercharger) or
lack of take-off power (turbo-lag). Hybrid vehicles have electricity in
abundance compared with traditional vehicles. The TurboFlow™ design
uses this abundance to provide significant amounts of "air-on-demand".
The TurboFlow™ system can run independently of the engine and it can be
used throughout a driving cycle. The TurboFlow™ can inject air into
small displacement (sub-2000 cc engines), ideal for hybrids, in
situations where either power takeoff would drain too much power, or
exhaust gas pressure would be insufficient.
The key differences between the new TurboFlow™ and the existing TurboPac™ design are:
- Reduced footprint and weight for the entire assembly
- Secondary "surge" power
- "Smart" controlled compressor output
- Smaller, more efficient motor controller
- Reduced manufacturing time and cost from using "off the shelf" components
Three examples where small-engine vehicles have tough demands are:
Highway passing
Highway entry on ramps
Initial acceleration
These situations place high demands on electrical drives, they create
mechanical turbo-lag, and supercharger power losses. All are all
difficulties for vehicle designers. The responsiveness of the TurboFlow
™
system means a surge of power for small-displacement engines and
hybrids. The ‘smart controller' approach of the TurboFlow™ enables "Air
On Demand" air injection for vehicle designers. Air On Demand means
that fuel-engines can be sized for minimum weight in addition to
improving driving cycle performance."
Engine design utilizing TurboFlow™ technology means that smaller,
lighter engines can be used, in place of larger heavier engines, for
many driving cycles. In addition to delivering "Air On Demand" without
mechanical power losses or exhaust modifications, the units draw
virtually no power when not needed."
