Description

The necessary tests can be carried out to obtain the data characteristic of the motor operation, familiarizing students with the curves presented by the manufacturers of the same as a sample of their operation.

The test bench for combustion engines has two motors, the motor to be tested, and therefore acts as such, and the braking system, which consists of a three-phase asynchronous motor controlled by a frequency inverter. The can function as both engine and generator.

COMPUTERIZED SYSTEM:

The Engine Test Bench (TD 01.2) is equipped with a complete computer system, which significantly streamlines the work of tests or practices.
The system is able to control and register all the variables of the equipment.
The tests can be done manually or automatically, just indicating the required variables and indicate how many points we want the graph of results. This way you do not waste time in aiming results and drawing the graphs by hand.
