Metrology workshop and organ bench LORRTEC

We have modern equipment to control the various components of an engine:

• Cylinder head blower to validate the permeability of the ducts as well as the swirl/tumble of the engine.
• Bench of injectors to validate and balance the flow rates.
• Camshaft bench to check and study timing diagrams with precision.
• Digital spring tester to calibrate the return forces at the valves.
  
• Test bench for mechanical injection pump type Bosch, Lucas, Kugelfischer… to develop these old systems.
• Three-dimensional measuring machine to control any mechanical part.

Vehicle and engine test benches LORRTEC

We are equipped with a 4WD ROTOTEST 1000hp vehicle test bench, comparable to a set of engine benches coupled to each driving wheel of the vehicle. This measuring instrument is extremely precise thanks to the high-resolution torque sensors measuring the force directly at the wheel hubs. Dynamic and stabilized measurements can thus be performed during engine tuning.

We also have a SCHENCK engine test bench from Formula 1 allowing us to fine-tune all types of engines with power up to 1000 hp and speeds up to 18000 rpm .
