For vehicles coming in addition to the engine dynamometers and chassis dynamometers are used, on which the entire vehicle can be checked. Brake tester and transmission test benches (short aggregates benches) are used to the testing of passive components and require a corresponding load machine.
An engine test bench can serve two purposes: The investigation of a motor has mentioned parameters are measured and recorded. The aim is either to check) for compliance with predetermined values (in production, or the optimization of properties such as energy consumption and environmental pollution (in development).
The investigation of engine has durability. In this case, the engines are operated under extreme conditions to address, in a customary use of much shorter time compared to the vulnerabilities of engine components.
Traditional dynamometer engine test stands allow you to set individual operating points of the test engine stationary, whereby the parameters to be measured usually entered in a speed / torque chart. Suffice here relatively simple load machines brakes, by which one can set the-applied by the test object (engine) torque.
The boundary conditions to be observed today may make it necessary for at least the engine manufacturer to run on test stands and dynamic cycles that are close to the realistic engine. As to both rapid changes of torque and speed, as well as a reversal of the torque direction (push mode) are necessary in that case, only electrical load machines are used.
