shall be measured and shall not exceed requirement.
4.5.4.18.4 Fuel shut-off test. To determine fine conformance to 3.4.18.4, the engine shall be
operated at 50% of governed rpm, manual shut-off valve shall be actuated to "off" position. Time

actuate one bottle. After a time delay of more than 6 seconds but less than 11 seconds, the engine
shall have stopped and the system shall begin discharging CO2 into the engine compartment and in
the center of the engine "V". After returning the handle to its original position, a second
actuation shall discharge the remaining two bottles of CO2. Removal and weighing of each CO2
bottle after test shall show a minimum of 9 lbs (4 kg) of CO2 discharged during test.
