Multi Engine Test Bench
Product Code : EL-TELE-10701
Quick Answer: The Multi Engine Test Bench is a complete test stand used to measure the power output of internal combustion engines, consisting of a control and load unit paired with a choice of engine to suit customer requirements. It applies braking power to the engine through an air-cooled asynchronous motor with an energy recovery unit, with braking speed and torque precisely adjustable via a frequency converter, and it displays speed, torque, air consumption, and multiple temperatures while transmitting measured values directly to a PC via USB with included data acquisition software.
This test stand's main function is to provide the required braking power to the engine under test. The brake unit is an air-cooled asynchronous motor fitted with an energy recovery unit, and the braking speed and torque can be precisely adjusted using a frequency converter; recovering the braking energy back into the system makes for highly energy-efficient operation. Torque is measured by means of a suspended brake unit and force sensor.
The engine is mounted on a vibration-insulated base plate and connected to the asynchronous motor, so no vibrations are transmitted to the surrounding environment. The asynchronous motor is initially used to start the engine, and once the engine is running, the asynchronous motor and energy recovery unit act as a brake to apply a load to the engine, with the resulting braking power 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, and two separate fuel gauge systems allow a quick change between diesel and petrol operation. The switch cabinet contains digital displays for speed, torque, air consumption, and temperatures (engine cooling water inlet and outlet, exhaust gas, fuel, and intake air), while fuel consumption and cooling water flow rate in the engine, along with the calorimeter available as an option, are displayed in analogue form. The measured values are transmitted directly to a PC via USB, with data acquisition software included, and lifting gear is required to exchange the engines.
