A couple of months ago I spoiled myself in a major way and bought one of
the new Nissan Titan diesel trucks, equipped with a 5 liter turbo
Cummins engine. This is my first foray into the world of diesel engines.
I expect there are a few people on the list that have more experience
with the things.
My questions all revolve around cold weather starting.
What is considered cold for a Diesel?
Should plugging in the block heater make a difference?
Can glow plugs be flakey?
It's not all that cold here right now. Anything below about -16ºC is an
issue for this truck. This morning was -27ºC, and it took multiple
attempts to get it running. Starting is completely automatic, the only
control the driver has in this regard is a PHD button that initiates the
start cycle. After that, it's up to the truck.
I like the truck, but if I need to go out and start it and warm it up
every 5-6 hours during the cold months, it is not going to be a pleasant
vehicle to own. They say don't idle it for extended periods because of
the particulate filters, and if it is idled to much, it goes into
perpetual regeneration of the filter, which means it's dumping raw fuel
into the exhaust to burn off the soot. This drops gas mileage to about
60l/100km. One it is running, it is a joy to drive.
If there are any diesel wonks on the forum, your thoughts would be
appreciated.
thanks
