Diesel Newbie Question

[Got Smoke?]

Ok I'm still diesel dumb, but I have a question that I didn't want to myself by asking on the normal boards.



Does the Cummins use Glow Plugs?



I've heard this arguement forever and I want to know for fact.



Thanks

Glow plugs?

First of all welcome aboard. The second generation of Dodge Cummins (94 thru present) do not have glow plugs. There is a heater grid on your intake manifold that pre-heats the air prior to starting. That is why they dont need glow plugs. Please feel free to jump in here illflem. (He knows alot more about these things than I do.

David, you about said it all. The only thing I can add is that grid intake air heater starting aid systems seem to be more reliable but draw more juice than glow plugs. Glow plugs are a consumable item like spark plugs, they have to be replaced. I've never had to replace a grid heater element, just solenoids and wiring. If I'm not mistaken newer PSDs have switched over from glow plugs to intake heat.

Jim,



I don't believe the 1st gens had glow plugs.

Joe G. Good for you... they dont have GLOW PLUGS, I was talking about the GRID HEATER. sorry for not being more explicit.

Just for your general interest, glow plugs are typically found on indirect injection (pre-combustion chamber) engines. The B is a direct injection engine and thus some other type of starting aid is used. By the way, the B will easily start without cycling the grid heaters down to about -15*C. (Just a little more smoke!)

Here is a picture of the grid heaters. Scroll down a bit. Even though these grids are on a 24-Valver, you get the idea.
