Section III Vehicle/Engine Requirements and Expectations

Life expectation (in hours or miles): _________________________________

Duty Cycle expectation (percent time compressor operates loaded):

Recommended Test Procedure:

Installation angles: Engine installation angle: _____________________________________

Compressor rotated angle: _____________________________________

Gradability (vehicle operation on slope):

Side: _______________________________________________________

For/Aft: ____________________________________________________

Percent of time operated on inclines? _____________________________

Compressor delivery/system pressure: _________________________________

Engine rated speed: _______________________________

Air compressor drive ratio: _________________________

5% to 25% 25% to 35% greater than 35%

Install a pressure switch (60 - 90 psi) in the governor signal line. Record the switch voltage or continuity during vehicle operation. The duty cycle is the quotient of the compressor loaded time (low pressure in the signal line) and the total time. The total time of the test should reflect a typical operation cycle of the vehicle.

Was duty cycle measured? NO

YES

Measured value: _____________
