HYBRID AND FUEL CELL VEHICLES
Gas engine powered vehicles are an immediate application for the
commercial use of 4QMET technology.
The 4QMET can facilitate
the transition from present-day gas engine powered vehicles to electric
motor powered vehicles. The 4QMET should be able to maintain and
extend the time of what is likely to be a transition period from
gas based to electric based automotive power. The 4QMET can extend
the duration for acceptability of gas engine and hybrid powered
vehicles, due to dramatic reduction of gas consumption and the reduction
in generation of pollutants.The 4QMET could be used with a gas-powered
engine to increase efficiency by a significant factor in stop/start
type driving (e.g. enabling highway driving efficiency under city
The 4QMET's positive
impact on energy usage efficiency will dramatically increase the
performance of a gas engine or hybrid (gas engine & electric
motor) powered automobile compared to standard, automatic or CVT
type transmissions. The 4QMET makes it possible to maintain existing
automobile performance levels while enabling size and cost reduction
of the gas engine (both the gas engine and electric motor in hybrid
The 4QMET enables
an unprecedented reduction of transmission size and cost.
HYBRID AND FUEL CELL VEHICLES
The 4QMET is a transmission that enables a motor to always operate
at a constant speed and at the motor’s peak efficiency, while providing
controlled output speed and torque conversion. The 4QMET's conversion
of constant motor speed to variable output speed is accomplished
electronically. Unlike mechanical CVT’s, no external power is required
to perform the conversion. Therefore all efficiency benefits are
fully captured in energy savings.
The picture below
shows the 4QMET mounted in a vehicle powered by a single electric
motor. The source of power for such a vehicle could be a fuel cell,
or in today's applications, a hybrid power source (e.g. small gas
powered engine powering a generator). Use of the 4QMET significantly
improves efficiency of operation resulting in dramatically lower
The 4QMET principle
of operation enables it to recover regenerative energy during braking
and store it in a battery OR for fuel cell applications, in a subsequent
process, generate hydrogen to provide additional fuel for fuel cells.
The 4QMET's advanced
architecture can be used for a 4 (or 2) wheel drive electric motor
powertrain. Automotive companies are moving towards this type of
powertrain in which mechanical linkages are elimnated and replaced
by electronic control of speed. The benefits of this approach include
full time all-wheel drive and elimination of the differential. The
image below shows the implementation of the 4QMET in a 4 wheel configuration.
Each motor is connected to its wheel via a 4QMET (scaled in size
to the power requirement) controlled by a 4QMET controller.
THE RACE FOR A VIABLE FUEL CELL VEHICLE
The technical problems which have to be overcome to produce an economically
viable fuel cell are well documented. At the present, it appears
that it will take years to reduce the cost of fuel cells to make
them economically viable for high volume automotive use.
4QMET may dramatically accelerate the time to introduction of economically
viable fuel cells for automobiles.
The 4QMET technology
makes it possible for automobiles to operate at optimal highway
driving efficiency even when used in city driving conditions. This
increase in the efficiency of energy usage means that an automobile
requires a lower rate of energy consumption during its operation,
could make it possible to for a fuel cell powered vehicle to use
a much smaller capacity fuel cell. This should translate into a
reduction in fuel cell size and cost and enable volume production
of affordable fuel cells for vehicular applications, possibly years
before they would otherwise become economically viable.
