TurbopacTM 2500 Series
(For use worldwide, subject to country codes and local
regulations. In the U.S.A. for heavy-duty mechanical unit injection engine
applications and for off-road use to and including model year 1994. For
other applications or model years please contact Turbodyne
Sales.)
Turbodyne's TurbopacTM system is an
electrically powered supercharger that monitors the demand for power and
delivers instant boost to the engine during transient engine operation.
TurbopacTM 2500 Series can be optimized for
applications for a variety of system voltages, pressures, flows and duty
cycles.
Turbodyne's TurbopacTM product line is designed
to meet the demanding operating environment of heavy-duty, as well as
medium-duty diesel engines. TurbopacTM systems have shown
substantial pollution reduction capability for satisfying stringent
environmental laws in the USA and abroad. TurbopacTM 2500 model
is being used for the EPA Urban Bus Retrofit Program.

TurbopacTM Operation
Technically
referred to as an "Electronic Demand Charger" (EDC), TurbopacTM
is an electronic supercharger that uses electrical power for short periods
of time for initial acceleration, passing and hill climbing.
TurbopacTM is capable of significantly increasing power output
of engines during acceleration.
TurbopacTM will engage
and supercharge the engine via an activation signal from a throttle
position via potentiometer or a pressure switch. It will switch off
automatically as the manifold pressure reaches 8 PSI and the engine load
is stabilized to avoid excessive demand on the vehicle's electrical system
and reactivated when demand for increased power is made.
A solid
state sealed motor controller is connected to the vehicle's battery
system. The controller provides 3-phase current to a Permanent Magnet
Brushless DC motor. The motor is directly coupled to the compressor which
spools up to operating speed in a fraction of a second.
A Y-shaped
check valve is connected to the intake manifold to provide boost pressure.
Ambient air is supplied via a connection to the air filter. An activation
circuit senses change in throttle pedal angle on diesel engines and
manifold vacuum on gasoline engines.
When the
TurbopacTM system is applied, more oxygen is available for
optimized combustion during the otherwise fuel rich operating period,
resulting in reduced emissions (PM, CO, HC, and smoke). The intake air is
pressurized and the supercharged air is fed directly into the engine.
Unlike catalytic convertor and trap technologies,
TurbopacTM systems do not exhibit engine performance
degradation in the form of reduced performance due to the accumulation of
soot, and therefore exhibit longer life.
Electrical
Requirements
The standard vehicle alternator and battery are
generally adequate for operation of the TurbopacTM. Power
requirements of the TurbopacTM depends on the size of the
engine and therefore quantity and mass flow of air. A larger engine takes
more air and therefore more electrical power is needed for a given boost
pressure. As an approximation, for any given engine, TurbopacTM
draws about 25% of the electrical current of a starter motor for the same
engine, but only for short bursts of several seconds.
Installation
The TurbopacTM System
modular design can be applied in various configurations and
TurbopacTM can be applied to a variety of diesel, gasoline,
natural gas, other alternative fuel engines and naturally aspirated and
turbo-charged engines.
The TurbopacTM System includes
all of the required functioning hardware. It does not include the hardware
required for a specific engine/vehicle installation. The customer or
installer must provide the required brackets, hoses, clamps, nuts and
bolts to complete the installation.
The standard functional
TurbopacTM 2500 System consists of:
TurbopacTM Compressor Unit; Solid State Electronic
Controller; Throttle Position Sensor or a Pressure Switch; Wiring Harness;
Y-Shaped Pipe; Check Valve; Fuse and Holder; 8 PSI Pressure Switch. An
Installation and Operation Manual is included.
The
TurbopacTM compressor unit is installed in the engine
compartment and is placed between the air intake of the engine and the
intake manifold. The controller can be installed inside or outside the
engine compartment.
TurbopacTM is a "stand alone"
system that has no engine driven belts or gears, requires no lubrication
and is manufactured with pre-lubricated precision ball bearings.
TurbopacTM is an electrically operated air enhancement
device and its incorporation into an engine may require modifications to
the fuel, ignition and electronic control systems of an engine.
Modifications should be done by expert installers.
Installation of
a TurbopacTM may interfere with the performance of
anti-pollution devices. Please consult with Turbodyne Engineering for
availability of exemptions on various engine types.
