ABSTRACT:
The infrared energy detection device is a small, battery powered radiometer which measures IR energy emitted from an engine exhaust device, compares it with programmed energy levels, and displays whether the measured level falls within acceptable limits. It is calibrated against engine torque; and, by means of green and red lights, indicates the level of IR emissions. If emissions are below a predetermined level, a green light will be illuminated. Conversely, if emissions are higher than design levels, a red light will be illuminated indicating degraded performance of the engine IR suppresor. In addition to the green and red light indication, a digital display of IR intensity is also provided.
