1065.525—Engine starting, restarting, shutdown, and optional repeating of void discrete modes.
(1)
Start the engine as recommended in the owners manual using a production starter motor or air-start system and either an adequately charged battery, a suitable power supply, or a suitable compressed air source.
(2)
Use the dynamometer to start the engine. To do this, motor the engine within ±25% of its typical in-use cranking speed. Stop cranking within 1 second of starting the engine.
(b)
If the engine does not start after 15 seconds of cranking, stop cranking and determine why the engine failed to start, unless the owners manual or the service-repair manual describes the longer cranking time as normal.
(1)
If the engine stalls during warm-up before emission sampling begins, restart the engine and continue warm-up.
(2)
If the engine stalls during preconditioning before emission sampling begins, restart the engine and restart the preconditioning sequence.
(3)
Void the entire test if the engine stalls at any time after emission sampling begins, except as described in § 1065.526. If you do not void the entire test, you must void the individual test mode or test interval in which the engine stalls.
(4)
Except as described in paragraph (d) of this section, void the test if the engine stalls at any time after emission sampling begins.
