Integration of the dynamometer control system with automatic calibration tools for engine system calibration is often found in development test cell systems. In these systems, the dynamometer load and engine speed are varied to many engine operating points, while selected engine management parameters are varied and the results recorded ...
Schematic water brake on a dynamometer A 4-minute ‘how-it-works video’ tutorial explaining how engine-dynamometer water-brake absorbers work.. A water brake is a type of fluid coupling used to absorb mechanical energy and usually consists of a turbine or propeller mounted in an enclosure filled with water.
The specified Force can be distributed evenly between the axles or in different amounts between different axles in the case of multiple axles chassis dynamometers. Speed control/Velocity constant - dynamometer holds the set speed regardless of force or other parameters. For example, if a vehicle tries to accelerate in this mode, dynamometer ...
A 6-minute ‘how-it-works video’ tutorial explaining how engine-dynamometer and chassis dyno eddy-current absorbers work. Most chassis dynamometers and many engine dynos use an eddy-current brake as a means of providing an electrically adjustable load on the engine. They are often referred to as an "absorber" in such applications.
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...

A machine-tool dynamometer is a multi-component dynamometer that is used to measure forces during the use of the machine tool. Empirical calculations of these forces can be cross-checked and verified experimentally using these machine tool dynamometers .
Efficiency decreases for small internal combustion engines. A 67 ml 4-stroke engine converted to hydrogen and tested with a dynamometer at the best operating point (3000 rpm, 14 NLM (normal liters per minute), 2.5 times stoichiometric air/fuel ratio) achieved 520 W and 21% efficiency. In order to measure the vehicular efficiency an also ...
