General Description
ITRAC powertrain department was established in 1998.Powertrain department perform a wide variety of engine endurance, performance and functional testing programs for engine manufacturers and their suppliers. Engine endurance evaluations are performed for customers including light-duty OEMs, passenger car OEMs, industrial equipment manufacturers and engine components suppliers.
ITRAC engine test stand configurations meet diverse testing requirements and needs. Precision data acquisition and control systems provide flexible and repeatable engine control. Data acquisition rates vary depending on customer requirements, with typical rates at once/minute and once/stage. Humidity, temperature and pressure intake air control is available, as well as precise control of various other temperatures and pressures such as engine oil and coolant using PID loop control.
