Multi Engine Test Bench
The main function of the test bench is to provide the required braking power.
The brake unit is an air-cooled asynchronous motor with an energy recovery unit.
The braking speed and torque can be precisely adjusted using a frequency converter.
The recovery of the braking energy into the system provides for highly energy-efficient operation of the test stand.
The torque is measured by means of a suspended brake unit and force sensor.
The engine is mounted on a base plate and connected to the asynchronous motor.
The base plate is vibration-insulated, so no vibrations are transmitted to the surrounding environment.
The asynchronous motor is initially used to start the engine.
As soon as the engine is running, the asynchronous motor and energy recovery unit act as a brake for applying a load to the engine.
The braking power is fed back into the electrical system.
The lower section of the mobile frame contains fuel supply tanks and a stabilization tank for the intake air.
Two separate fuel gauge systems allow the quick change between diesel and petrol operation.
The switch cabinet contains digital displays for the speed, torque, air consumption and temperatures (engine cooling water inlet and outlet, exhaust gas, fuel and intake air).
The fuel consumption and cooling water flow rate in the engine and the calorimeter available as an option are displayed in analogue form.
The measured values are transmitted directly to a PC via USB.
The data acquisition software is included.
Lifting gear is required to exchange the engines.
