Engine Dynos
Saenz engine dynos are designed for professional engine testing. Since 1974 we have been manufacturing smooth control, robust, safe and low maintenance hydraulic brakes. Equipped with Smac data acquisition system with automatic control of RPM and motor torque that allows to perform tests with maximum precision, sensitivity and repeatability.
DK y DKI
Kart and motorcycle engine dynos
We build different versions, with hydraulic brake and inertial wheel. Both versions are versatile designs adaptable to any karting and/or motorcycle engine. These benches do not require installation.
DK - Engine dyno with hydraulic brake
DK bench includes a DR1 brake that has the advantage of a low inertia aluminum rotor which deliver an excellent control and response on small engines. Coupling to the motor is by chain with protector and with an interchangeable winder in order to test different relations to the engine.
The dyno pump, supplies the brake to regulate the load on the motor. At the brake outlet, the water discharges to the tank located inside the dyno structure. As optional, an engine starting system and command desk can be added.
DKI - Inertial Wheel Engine Dyno
DKI bench has a flywheel with enough inertial load to perform excellent quality tests. The wheel is mounted on anti-reverse bearings that disconnect the steering wheel from the engine at the end of the tests. The dyno has an intermediate axle that simulates the wheel axle of vehicles to simulate real conditions to test the transmission.
The dyno structure also includes a universal motor mounting base. As optional, an engine starting system and a command desk can be added.
Data acquisition system for Dynos (SMAC)
SMAC is a powerful data acquisition system that works with the highest technology. It is a modular system that allow to increase as much data channels as required. Communicates to the computer through optic fiber what avoid electric noise troubles which are very common on a dyno environment. The software is very friendly with multiple tools to analyze the information obtained.
The acquisition software shows every test curve at real time during the essay. Results can be seen on flexibles graphics where every data can be compared and analyzed with as many tests as required. Multiple format Data tables are built to make the desired engine reports.
Auxiliar Sensors
Weather Station: reads the temperature, moisture and pressure conditions in the test cell. The software calculates with this information the correction factor for torque and power of the engine.
