  • 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.

    Gasoline and diesel engine Dynos

    DS are the most versatile brakes on the market. They can be used to test from racing engines to fast diesel engines with great stability making it the ideal dynamometer for research, development and teaching.

    Built with hydraulic seals and high-speed bearings that give the brakes long life with minimal maintenance. The brake is mounted on a metal base coated with epoxy resin where the braking water is discharged.

    The dynamometer is also equipped with a 7.5hp electric motor starting system with an automatic ratchet and pulley mechanism. It is linked to the motors with a drive shaft with joints protected by a safety cover.

    DS Brakes capacity for steady conditions and smooth control


    Automatic Control

    DS dynos are equipped with a control system that allows automatic tests, ensuring excellent repeatability, very comfortable and easy operation and eliminating the "operator error". The control sets the brake load to adjust the engine RPM automatically and according to the configured RPM limits and test length, it runs a test only by pushing a button.

    It includes an electronically operated valve that avoids going through the command console with the water pipes. The valve can also be commanded with a knob to work manually in the traditional way.

    Engine docking cart

    The engine base allows the motor to be mounted outside the test room and then easily entered and fixed to the brake base. With capacity to mount engines up to 600kg and two adaptable rear plates for different engine blocks and flywheel sizes.

    Control and Command Desk

    Stainless steel board, contains all the dynos commands, throttle body actuator and brake torque control. With a 24” led TV where the dyno software is displayed.

    Engine cooling column

    Replace the car radiator in the dyno, keeps the engine water stable at the desired temperature.
    Capacity: 600hp

    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.
