Precise control of the water equates to precise control of the load applied to the engine. DTS designed an exclusive stainless steel spool type valve that is extremely precise in the flow control.

To further enhance the precise control DTS uses it's exclusive valve on both the inlet water and outlet water of the absorption unit. Most other waterbrake systems control only the inlet water or the outlet water but not both.

The dual valve control also allows the waterbrake to respond quickly to abrupt load changes such as a Nitrous Oxide "hit" and it increases the overall system torque absorbing capacity.

In an automatic sweep test where the operator sets a starting and ending rpm range. The dynamometer will automatically control the engine's load to accelerate it through the set rpm range. You select various rates of acceleration (rpm per second).

DTS designed the load control system as a proportional band type system. Which allows the engine to do what it wants too naturally. An internal combustion engine is not linear in its power output through a sweep range. DTS does not hold the engine to a precise rate of acceleration, so if the engine wants to accelerate faster or slower at given points through the sweep range the DTS system allows it to do so without loosing control of the engine. This is extremely valuable in evaluating the data because you have information that engine did rather than information the dynamometer allowed the engine to do. Also you have a time of the sweep that has value.

The engine docking cart improves the versatility of adapting various configured engines to the dynamometer. All DTS systems have integrated starters built in the system so a bellhousing, flywheel or engine starter is not required although can be utilized if the operator chooses.

Engine connection is through a special compliant driveshaft that absorbs the torsional vibrations of the engine. This allows for direct coupling to the crankshaft.

The engine docking cart / driveshaft design also allows for excellent clearance for headers and exhaust systems.

The data acquisition system has six graph pages and 7 numeric pages to evaluate the data. Up to four operator selected data channels can be plotted on each graph page and up to three different runs or three different engines can be plotted against each other for evaluation.

The industrial heavy duty design and construction means years of trouble free operation. All DTS systems are built for continuos operation (24/7/364) and carry a full two year warranty.

For training, answering questions, software updates and trouble shooting all DTS systems include the online service DynoCom. DTS technicians can access any system worldwide through a phone line and operate as a satellite location. So training is quick and simple, any upgrades to software can easily be downloaded and of course any questions can be answered in extreme detail. There is never any charge for the DynoCom service.
