DynoMight IIISeries Pro
·DynoMight IIIis a professional Data Acquisition System for all
Dynamometers, e.g. Engine Dynamometers,
Chassis Dynamometers (Rolling Roads) and also for Flow Benches, Shock Absorber-,
Cam- and Valve Spring Checkers etc.
makes it possible to upgrade and enhance any dynamometer to a level which is capable
of keeping up and even superseding all but the most expensive of test systems available.
·DynoMight III is
very universal and due to its modular design it can be expanded into an extremely
powerful tool capable of fulfilling many complex uses.
·DynoMight III is
extremely easy to use and therefore does not require the perusal of thick instruction
On the one hand, the TAT DynoMight systems
are very easy to use, on the other hand they lack no essential
features. Quite the contrary, a great many powerful and useful functions are part of every one of our systems,
right down to the very smallest.
This type of system has quickly become a favourite amongst
European Super-Touring Car works teams with
40% of them using such a system to develop and map their engines for optimum performance. One big
Japanese car manufacturer has also acquired one of our systems for his R&D centre in the US where he
develops and produces Indy cart engines and special engines for off road races.
For readers not familiar with the 2.0l Super-Touring
Car series we would like to explain the significance of this:
this is the largest saloon racing series in Europe with nearly all cars either built or commissioned by the car
manufacturers themselves, Peugeot, Nissan, Honda, BMW, Ford, Renault, Audi, Vauxhall/Opel (=GM).
Engines are not allowed to exceed 8,500 rpm in this series. Nonetheless, these engines produce over 300 Hp.
Due to these all being only small 2.0l normally aspirated 4-cylinder engines they all have extremely explosive
power and torque characteristics. To make matters even worse, their inertia is very low. This is a worst case
scenario for any Engine Dynamometer and its Data Acquisition System. We are proud to say, that even under
these unfavourable conditions our systems still attain unrivalled fast response and yet high consistency of all
But these are not the only extreme conditions our test
systems have been subjected to in the past. On behalf of
a large car manufacturer our very universal dyno acquisition system (which can incidentally also be used for
Chassis Dynos, Flow Benches, Cam and Valve Spring Checkers, and many other uses...) was successfully used
as a mobile in-car data collection unit to perform safety checks of pressures and temperatures apparent in
automotive fuel tanks in the Arizona dessert.
The most significant advantages DynoMight III at a glance:
· Can be used for all Dynamometers, be they controlled manually or automatically
· High level of accuracy and consistency of all test results.
Highest level of consistency and repeatability are ensured through a unique mathematical
engine cycle synchronous sampling, successive averaging and infinite impulse response filtering. Although
instruments and displays respond very quickly, outside sources of interference are rejected leading to
remarkably consistent test results.
Great care has been taken to maintain easy-to-use and thus user-friendly software
many powerful features have been included, even users with little or no previous computer experience will
be able to use this system very quickly to their full benefit. The examination of thick instruction manuals will
not be necessary.
· Many time saving and automated features. The number of necessary keystrokes is reduced to a minimum.
Visual and acoustic warning and alarm functions alert the operator when readings exceed
operating ranges. A number of emergency actions can be defined in the event of an alarm.
Data Acquisition, data processing, and display of readings occurs with real-time
characteristic. This means
that all readings are displayed without significant time delay (merely fractions of a second, depending on
All sensor values (temperatures, pressures, etc) and calculations (corrected power and
are displayed utilizing so-called 'virtual instruments' on a PC monitor. These are similiar to 'real' physical
analog instruments one would expect to find in a console. In contrast to these however, virtual instruments
have the advantage of being easily grouped, reset for different uses, and all being located on an easy to
read off screen. Should you already have a 'real' physical console you can of course still use this and simply
run it alongside the computer system. Simply 'tap' sensor outputs as appropriate and feed them into the Pro
Data Acquisition electronics.
All instruments and channels can be configured freely by the user. Any sensor can be
connected to any
channel, only a few limitations exist. This gives these systems their truly universal aspect, allowing them to be
used for a myriad of applications, Engine Dynos, Flow Benches, Chassis Dynos (Rolling Roads), Cam and
Valve Spring Checkers. Many more applications are possible. One was a mobile fuel cell test system which
was successfully realized by a major car manufacturer testing under extreme conditions in the Arizona desert.
All relevant parameters controlling the data acquisition cycle and data processing can be
set to ideally suit
the type of test. Other systems in this class do not usually allow this. The system response can be set exactly
to your liking, i.e. the displayed sensor values can be displayed very dynamically (fast) or damped (slower
but more stable). Even in a worst case scenario (small 4 cylinder engine with extremely low inertia and
explosive power band = 2.0l Super-Touring Car engine) it is not unusual for our Pro systems to maintain
stable readings for power and torque within a deviation of only 0.5 Hp which equates to less than +/- 0.1 % of
the full scale value - by any standards a very respectable achievement.
All tests can be fully commented. All engine info with specifications, modifications and
customer name etc.
can be added. There is no limit to the length of the possible entry. Tests without sufficient comments can
quickly become meaningless if the exact engine spec. and test conditions are no longer known. All
observations during a test can also be added to the comments after the test. Also, all previous comments
can still be edited after the test.
Reference Tests: during a test the system will constantly compare current values and
reference values from
a previously recorded test run with regard to power, efficiency, emissions etc. and indicate whether
improvements have been made or not. An essential tool for fast and optimized mapping of engine
The system requires no special sensors and provisions have been made to enable the
connection of nearly
any sensor. The software even provides a facility to find characteristic formulae of non-linear sensors. This
means that even OEM sensors can be connected directly to the system (together with a suitable series
resistor). Also, lambda-probes can be connected without any interface circuitry. Lambda values can be
calculated directly from any lambda-probe's voltage signal during a test.
The system calibration and setup can quickly be changed. This allows for employing engine
configurations and simply changing these as appropriate. Graphing-templates for different engines can be
defined. These are then automatically selected and ensure that you are always displayed exactly the curves
you wish to see with the correct scaling for the correct test. This will save a lot of time in the long run as it
avoids unnecessarily repeating keystrokes.
All calculations for the power correction factor, corrected power, fuel consumption,
piston speed, etc. are
performed during test time and the results are instantly displayed throughout the whole test.
All calculations are mapped into a look-up table at startup of the system. This
significantly reduces execution
times for calculations which means that the system has no problem processing the incoming 50.000
samples per second from the highly integrated and miniaturized full SMT (Surface Mount Technology)
electronics. In fact, operation of the optional 16-bit A/D module running at an even more than respectable
200.000 samples per second is handled just as smoothly.
All readings are displayed in clear order and can appear on up to ten switchable screens
(depending on the
number of input channels).
Digital and parallel high speed data transmission between sensor input box and PC. This
does not only allow
for 'neat' connections but more importantly provides the system with the essential high grade of rejection
capability to outside sources of interference (from ignition, alternator, etc.).
Only a minimum of keystrokes are required to activate the most important and most commonly
· All advantages of MS-Windows supported
All data and configuration information is stored in ASCII text format. This means that all
files can be read and
edited using any standard editor and also that all data can also be further processed in standard
spreadsheet applications software. Of course, easy-to-use setup tools come as part of the Pro system, so
changes to the system's setup can easily be performed.
Triple data security. Data points are immediately written to the non-volatile harddisk
memory. Therefore, no
data can be lost in the event of an unexpected interruption of a test. After completion of each test, the actual
data file is created. If necessary, all data points are automatically arranged in ascending order with respect
to engine speed, or also any other specified parameter. A test run can be paused and restarted again at
'Shell'-Button allows a quick jump into the working directory of the software to copy or
edit data or
configuration files. Also, a batch file can be automatically started on activating a single button. This could for
example be setup in such a way that the last test files are backed up to a floppy disk etc.
There is nearly no limit to the number of curves which can be overlayed and printed.
WYSIWYG print-outs in color or black and white to any inkjet or laser printer. What you
see on the screen is
exactly what is printed on your printer.
· Zoom function allowing magnification of any desired screen section.
'Magnetic' cursor which can be locked onto a desired curve and used to trace this for
exact values and also
to identify the curve..
· All test data can be viewed and printed in tabular form.
· Movable and sizeable Info Window in the graph to add further comments to print-outs.
Time saving templates including all information for curve selection, scaling, axis
assignments, position, size,
and additional comments text can be defined. These will be automatically applied to the corresponding test
Screens showing comparisons of different tests can easily be combined under a single name
the user to load these with only two keystrokes.
· Five different modes for triggering data storage are available to suit any requirement
Data can be stored manually on activating a key on
the keyboard, automatically by an automatic timer, by a
timer which is only activated when a certain sensor or channel reaches a certain value (level triggering; the
trigger could for example be if engine knock exceeds 20%)
· Optional High Speed modules running at 200.000 or more samples per second available.
