2. Engine test stand - Wikipedia

   en.wikipedia.org/wiki/Engine_test_stand

   An engine test stand is a facility used to develop, characterize and test engines. The facility, often offered as a product to automotive OEMs , allows engine operation in different operating regimes and offers measurement of several physical variables associated with the engine operation.

3. Emission test cycle - Wikipedia

   en.wikipedia.org/wiki/Emission_test_cycle

   Emission test cycles are typical tests for research and development activities on engines at automobile OEMs. The commonly used hardware platforms therefore are: engine test stand - for just a single engine; vehicle test stand (also "chassis dynamometer" or "chassis dyno" or "emission dyno") - for the complete car with engine

4. Mechanical device test stands - Wikipedia

   en.wikipedia.org/wiki/Mechanical_device_test_stands

   A mechanical device test stand is one specific type of test stand.It is a facility used to develop, characterize and test mechanical components. The facility allows for the testing of the component and, it offers measurement of several physical variables associated to the functionality of the component.

5. Engine stand - Wikipedia

   en.wikipedia.org/wiki/Engine_stand

   Engine stand (red) holding a partially disassembled combustion engine. An engine stand is a tool commonly used to repair large heavy gasoline or diesel engines. It uses a heavy cantilevered support structure to hold the engine in midair so that the mechanic has access to any exposed surface of the engine. They are often referred to as cherry ...

6. OBD-II PIDs - Wikipedia

   en.wikipedia.org/wiki/OBD-II_PIDs

   OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.

7. Drive shaft - Wikipedia

   en.wikipedia.org/wiki/Drive_shaft

   The automotive industry also uses drive shafts at testing plants. At an engine test stand, a drive shaft is used to transfer a certain speed or torque from the internal combustion engine to a dynamometer. A "shaft guard" is used at a shaft connection to protect against contact with the drive shaft and for detection of a shaft failure.

9. Dynamometer - Wikipedia

   en.wikipedia.org/wiki/Dynamometer

   A typical size ratio for common emission test cycles and most engine development is approximately 3:1. Torque measurement is somewhat complicated since there are two machines in tandem - an inline torque transducer is the preferred method of torque measurement in this case.
