Vehicle Testing Services
ETC has five vehicle labs equipped with a variety of chassis dynamometers and air handlers to test under extreme environmental conditions, providing ETC with optimal vehicle testing services.
| Vehicle Lab | Dynamometer | Absorbing Power (hp/kW) | Air Temperature Range (°F/°C) | Emission Sampling |
|---|---|---|---|---|
| Site 1 | Burke Porter 48" AC Dynamometer | 200/149 | -20 to 110°F -29 to 43°C | Spark ignition and diesel |
| Site 2 | Burke Porter 48" All-Wheel Drive AC Dynamometer, two independent rolls | 350/261 front, 450/336 rear | 0 to 110°F -18 to 43°C | Spark ignition and diesel |
| Site 3 | Burke Porter 48" AC Dynamometer, and Clayton ECE50 8.65" twin roll hydrokinetic dynamometer | 200/149 and 50/37 | 50 to 110°F 10 to 43°C | Spark ignition |
| Site 4 | Burke Porter 48" AC Dynamometer | 200/149 | 0 to 110°F -18 to 43°C | Spark ignition |
| Site 5 | Horiba 48” AC Dynamometer | 200/149 | 68 to86°F 20 to 30°C | Spark ignition |
Sites 1 through 4 feature Burke Porter 48” electric dynamometers. The AC dynamometers are used with vector drives that regenerate absorbed power back into the electric grid. Constant volume sampling (CVS) and raw exhaust sampling is available on all sites. Separate dilution systems are used for labs having both spark ignition and diesel sampling. All sites feature 20 Hz distributed data acquisition and digital control systems. Time-aligned reports are generated during testing and an automated data check is employed to enhance quality control procedures.
Site 5 is located in an independent area of the building. Site 5 features a Horiba 48” electric dynamometer and Horiba Instruments catalyst efficiency analytical system along with four bag CVS.
Vehicles may be tested under extreme environmental conditions. Ambient temperature ranges for each site are summarized in Table 1. ETC has the capability to simulate high wind velocity and extreme altitudes for optimal high altitude vehicle testing. A 100hp (75kW) road speed modulated centrifugal fan is available for conducting tests that require high velocity/high volume air flows (Figure 2). BASETM altitude simulation equipment described in Section 2.11 can be used in the vehicle or engine labs to simulate altitudes from 0 to 12,000 feet (0 to 3657 meter) above sea level.
