Dynomet DK offers a
range of roller type dynos:
For cars:
- inertia roller dyno for 2WD vehicles,
- inertia roller dyno for 2WD and AWD vehicles with an
option of synchronising front and rear sets of rollers,
- inertia roller dyno for 2WD with an eddy current brake
for steady state testing,
- inertia roller dyno for 2WD and AWD vehicles with an
eddy current brake for steady state testing and an
option of synchronising front and rear sets of rollers.
Dynomet DK also makes motorcycle roller dynos and dynos
for 1:5 scale model cars.
Features common to all
Dynomet roller dynos:
1. The rollers are very heavy, weighing close to 1000 kg
per axle. That's almost twice as much as rollers found
on other popular dynos. The heavier the rollers the
longer it takes to accelerate them, allowing for more
precise tests with sufficient load. Light rollers will
have problems even with new 2.0 and 3.0 diesel engines due to their
high torque values. With the DYNOMET heavy rollers, cars
with up to 700 HP can be measured in inertial mode,
which gives up to 1400 HP with the AWD dyno.
With the optional eddy current brake up to 1000 HP per
axle can be measured.
2. The rollers are knurled to eliminate wheelslip and
reduce noise.
3. Maximum roller speed - 360 km/h (225 mph).
4. Rollers are balanced to lessthan 1 gram.
5. The optional eddy current brake, KLAM CFK-140, has a
maximum braking value of 1700 Nm (1250 ft/lb).
6. Dynos with the optional eddy current brake can work
both in inertia mode and brake mode, where desired
engine rpm or speed can be set.
7. Power and torque graphs and current power output for
dynos with brakes.
8. Ability to compare up to 4 graphs, handy if comparing
'before' and 'after' graphs.
9. Display of speed, rpms and data from up to 8 auxiliary sensors (intake, oil, water temperature, air/fuel
ratio, EGTs etc.) with ability to log them during tests.
DYNOMET software has in-built DIN70020 correction.
For all AWD dynos the car's wheelbase can range from 218
cm to 330 cm.
AWD dyno dimensions: 532 x 255 x 65 (cm; length x width x
depth),
total weight - ca. 4500 kg.
2WD dyno dimensions: 100 x 255 x 65 (cm; length x width x
depth), weight - ca. 1100 kg.
DYNOMET dynos are modular
and can be upgraded at any time.
2WD dynos can be upgraded to AWD and inertia dynos can
be equipped with a brake.
In the synchronised AWD
version one axle can be easily decoupled for cars with
single axle drive.
AWD DYNOMET dyno
Each set
of rollers knurled and connected together with a belt to
eliminate wheels slip.
Exemplary power test on a base DYNOMET inertia type
roller dyno without eddy current brake.
The car makes around 500 HP and 650 Nm, but thanks to
the heavy weight of the rollers the test
is possible and provides sufficient load for this
turbocharged engine.
Test conducted in 6th gear, maximum speed around 320
km/h.
