California CAFE requires shutdown, Calf mandatory option, not sure where else it extends to. Think it's just Ca., or trucks ordered for Ca. for now. This includes all Diesels... from GM, Dodge, etc
Pls correct me, if necessary..
This is how it worked with the 6.4, the 6.7 is clean idle certified so the ESS is fleet option but not a regulatory requirement for 6.7 trucks:
CALIFORNIA HEAVY-DUTY DIESEL ENGINE IDLING REQUIREMENTS
The California Air Resources Board approved a regulatory measure, effective January 1, 2008, to further reduce
emissions of toxics and criteria pollutants by limiting idling of new diesel engine trucks with a gross vehicle weight
rating (GVWR) greater than 14,000 pounds, with vocational exemptions for certain buses, school buses,
recreational vehicles, medium duty vehicles, military tactical vehicles and authorized emergency vehicles, as
defined in various California Vehicle Code sections. The regulation primarily requires manufacturers of new
California certified 2008 and subsequent model-year diesel engines in these trucks to incorporate a system that
automatically shuts the engine down after five minutes of continuous idling or to certify the engine to an oxides of
nitrogen (NOx) idling emission standard of 30 grams per hour.
• Vehicles over 14K GVWR with 6.4L diesel engines must be equipped with an Engine Shutdown System
(ESS) in California and select California Emissions States (Connecticut, Delaware, Georgia, Maine, North
Carolina, New Jersey, New York and Pennsylvania).
• Automatically ordered for vehicles being delivered to states with diesel engine idle regulations.
• Not available for ordering on vehicles with rear parking aid modules or manual transmissions.
• ESS automatically shuts down the engine after 5 min of continuous idling operation with the parking brake
engaged (15 min if the parking brake is not engaged) and the transmission set in “neutral” or “park”.
• Engines used in buses, RVs, military tactical vehicles and select authorized emergency vehicles are exempt
when ordered with option code 63E.
• ESS overrides:
Engine is operating in power take-off (PTO) mode
Engine coolant temperature is below 60F
Exhaust emission control device (DPF) is regenerating
Nevada was the delivery state. We had 4 delivered.
After 15 minutes of idleing they all shut down. I will have to go talk to the dealer to see if they can be reprogrammed to allow them to idle past 15 mins. I had hoped the high idle mod would work.
If the trucks have the idle shutdown option engaging the pto option in the SEIC should override the shutdown.
