PAMI’s versatile engine stand allows engines to be tested or operated independently of the vehicles and equipment they power. The stand is flexible to accommodate engines of different sizes and configurations.
The test stand is used to develop, characterize and test freestanding engines rather than complete vehicles. The stand’s primary test equipment component is an engine dynamometer used to measure torque and engine speed to determine power output directly from the crankshaft.
Engine stand specifications and features include:
- Engine cooling column
- Charge air cooler
- Dynamometer driveshaft with torsionally soft coupling
- Load control assembly
- 128 channels of dedicated data acquisition
Coupled with PAMI’s Data Acquisition Capabilities, a Wide Range of Performance Variables Can Be Measured
The equipment provides for different regimes of engine operation and measures several physical parameters of performance. When used with PAMI’s suite of data acquisition capabilities, a wide range of performance variables can be measured and optimized including:
- Engine power and torque output
- Angular velocity of crankshaft
- Intake air and fuel consumption rates
- Environmental pollutant concentrations in exhaust gas including carbon monoxide, different types of hydrocarbons and nitrogen oxides, sulphur dioxide, and particulate matter.
- Temperatures and gas pressures at several points on the engine body including engine oil temperature, spark plug temperature, exhaust gas temperature, intake manifold pressure.
- Atmospheric conditions such as temperature, pressure, humidity.
The engine test stand is integrated with the Vehicle Performance Facility and upgrades engine dynamometers currently in PAMI’s inventory.
Delivering a Number of Value-added Tests
The test stand and related equipment can perform a number of value-added tests to assess the engine performance while operating under load. These tests can include:
- Fuel efficiency and drivability under steady-state and transient conditions
- Component durability testing
- Oil and lubrication tests
- Compliance testing to relevant emission regulations
- Engine performance mapping or developing a multidimensional input-output map among different engine variables
- Alternative fuel comparative assessments.
