System (OIS), Low Pressure Fuel Evaporative Tester (LPFE).
Parts of the Visible Smoke Test Tailpipe Idle Smoke / observe tailpipe for 10 seconds;
Crankcase Smoke / observe PCV system for 10 seconds; BAR Snap Test / 3 Snaps total, final two
snaps determine Pass/Fail.

diesel and gasoline vehicles.
Throttle Snap Wait Time 3 Seconds is the wait time between the throttle snaps for both
diesel and gasoline vehicles.
Max Smoke Linger Time 3-seconds is the max time smoke can linger on a diesel snap test
and not cause a failure.
Gasoline Vehicle Smoke Failure Gasoline vehicles fail for any smoke / no linger time
requirement.
Timing Functional Test Criteria ±3 degrees is the BAR's Pass/Fail criteria for the Timing
Functional Test.
Calibration Time for EIS and LPFE 3-Days is the time the EIS Analyzer and the LPFE tester
require calibration.
