Fast turbocharger geometry adjustment for optimal performance

Geomet 2000 is a specialized bench for tuning and testing controlled turbochargers (VNTs). The equipment is adapted to the needs of turbocharger repair workshops.  As a rule, this bench is used for adjusting and testing turbochargers of trucks and cars, but its design also makes it possible to work with turbochargers of special vehicles and small boats.

The bench consists of a housing with a powerful air compressor inside which the vacuum (or air pressure) is created during adjustment and testing of turbochargers. The test bench is controlled by an industrial computer with a touch screen and a control panel located on the body of the test bench.

With the help of the simulator you can solve such tasks:

  • Diagnostics of controlled turbochargers (VNT) with vacuum, pneumatic or electronic (option) control.
  • Adjustment of the stop position of the airflow control mechanism will eliminate the “overblow” effect detrimental to the engine.
  • Adjusting the length of the actuator rod to adjust the moment of the airflow control mechanism actuation.
  • Check of the control valve N75 (a unique feature of the test bench) to analyze the faults of the turbocharging control system of the car.
  • Evaluation of the actuator spring wear degree for in-depth diagnostics of vacuum and pneumatic actuators.
  • Transferring the control program (option) when replacing the electronic actuator cover.
  • The simulator is adapted for joint work with the ATP-1000 tester-programmer.
Installation and fixing of the turbocharger on the stand is made with magnetic adapter, and for turbochargers made of non-magnetic material there are lugs for fixing by means of clamps. The standard adaptor kit allows the installation of 80 % of popular turbocharger models.

The bench adjusts and tests the turbocharger by comparing the inlet and outlet air pressure of the turbocharger when its drive is activated. Shaft rotation locking eliminates the need for an oil station, which reduces the bench’s maintenance and repair costs.

  • Installation time of the turbocharger from 5 to 15 seconds thanks to the mounting method and the magnetic adapter.
  • Any turbocharger can be installed, even those made of non-magnetic materials.
  • The ergonomic design of the stand allows free access to any part or unit of the stand, and the wide table allows to work unobstructed.
  • An air filter prevents even the smallest particles from getting into the turbocharger during testing, adjustment or diagnostics.
  • High repairability is due to easily accessible components and bench design.

 

Software features:
  • The “real-time” information display and the availability of tolerance fields make it easy to set up and work on the bench without special training.
  • The large “database of turbine characteristics” (more than 7000) can be replenished independently by taking the characteristics of a new turbine. This makes the stand in demand even after 10 years.
  • Calibration of the test bench is done by the operator in 10 seconds. It minimizes errors by automatically taking into account the ambient conditions of the working room.
  • The construction of graphs allows a qualitative assessment of the condition of each turbocharger element before and after the repair.
Mechanical Design
  • Vertical turbocharger mounting position ensures stable fixation and comfortable access to all components during adjustment and diagnostics.
  • Wide working area and ergonomic layout provide unobstructed handling of large and non-standard turbochargers.
  • Magnetic adapter and universal clamps enable fast installation of most turbocharger types, including both magnetic and non-magnetic housings.
  • Adapter design with expandable configuration allows workshops to easily adapt the bench to regional market requirements.
Air and Drive Systems
  • Integrated high-capacity air compressor generates the required vacuum or pressure for precise simulation of turbocharger operation.
  • Air filtration system protects the turbocharger under test from fine particles, ensuring reliable diagnostics and preventing contamination.
  • No oil circuit in the design simplifies maintenance, reduces operating costs, and eliminates oil-related service issues.
Control and Support Systems
  • Industrial-grade control unit with touchscreen interface combines intuitive operation with advanced testing functionality.
  • Locking system for turbocharger shaft rotation removes the need for an oil station and reduces system complexity.
  • Adjustable stop lock and increased pipe height make it possible to work with oversized or custom turbocharger designs.
  • Easily accessible internal components simplify servicing and reduce downtime.

An intelligent control system that enables high-precision, real-time tuning of turbochargers.

The step-by-step interface helps reduce turbocharger tuning time, eliminate human error, and ensure OEM-grade calibration accuracy.

Based on an industrial fanless computer with a touchscreen measuring unit enables a wide range of professional functions.

Popular Questions


Your questions — our technical solutions

The GEOMET-2000 test bench employs the Flow Bench method for static calibration.

  • Principle of operation: The test bench measures the volume of air passing through the turbine nozzle assembly when the blades are in their fully open position.
  • Rotor rotation: Rotor rotation is not required for adjustment using this method. This allows for precise “dry” adjustment, eliminating the need for pressurized oil supply, which significantly simplifies and speeds up the adjustment process.

The GEOMET-2000 test bench control system is designed as a universal solution capable of working with virtually any type of boost control system:

  • Vacuum and pressure actuators: The test bench allows for the calibration of conventional pneumatic actuators by measuring their stroke and actuation pressure.
  • Electronic actuators (REA/SREA): Full support for modern “smart” actuators. The system communicates with actuators via PWM, CAN, and LIN protocols.
  • Actuators with a potentiometer: The test bench allows for precision adjustment of pneumatic actuators equipped with a position sensor (potentiometer). The system reads the feedback voltage, ensuring calibration accuracy in accordance with factory tolerances.

The GEOMET-2000 test bench is designed as an all-in-one system for maximum autonomy:

  • Built-in system: The test bench is equipped with its own powerful centrifugal blower, which generates a stable airflow for measurements.
  • External air: Connection to the factory compressed air line is used only for testing pneumatic actuators (vacuum/pressure).
    No external connection is required for basic geometry performance tests.

In addition to basic adjustment of the blade opening angles, the test bench allows for comprehensive diagnostics of the unit:

  • Testing the N75 solenoid valve: The test bench allows for testing the functionality of the boost pressure control valve. This eliminates situations where the turbine is correctly adjusted, but incorrect valve operation on the vehicle leads to over- or under-boosting.
  • Measurement of clearances in the geometry: Detection of critical wear based on deviations in the actual airflow graph during the opening and closing of the geometry.

The test bench software automates reporting and helps build trust with end users:

  • Graphical report: Visualization of test results before and after adjustment in the form of graphs and tables.
  • Printing and export: Ability to print the report or save it as a PDF to send via email or messaging apps.
  • Branding: You can add your workshop’s logo and specific order details (vehicle VIN, customer name) to the report.
  • Archiving: All test results are saved to the test bench’s hard drive for future analysis or to resolve disputes.
