They call them Duraspeeds they're a ceramic sheathed glow plug . They get to 1000 degrees in two seconds full temp of 1300 by three seconds. It claims they are good to start lower compression modern diesels . Claims to Start as fast as a gasser

That got me thinking how about lower compression worn older diesels ?

They seem to have just came out. Not much info other than bosch's site.

If pencil type are fast than these must be light speed . Maybe another upgrade ?

Exactly....my engine starts just fine on my 4 year old set of Bosch plugs. Usually less than 1 second to start it.

Isn't it that some Isuzu and Yanmar diesels are equipped with, I assume, this kind of glow plugs....because they start like a gasser, and some of them don't even have a glow plug indicator light on the dash?

Did more research theyre putting them in nissans and renaults 2.0 diesel with mercedes interested in using them in bluetec systems. Checking prices on other ceramics it looks as if they would be 20 - 30 dollars a piece.

On another note VW tdi engines are using ceramics as we speak with a big recall switching them back to steel ones. It seems the tips are breaking off.

I guess all things "better" are not always the best !

When I saw that they where starting low compression diesels it gave me a sense of hope . Fabricating an adapter is a whole lot simpler than an engine change.

I thought there was hope of weening mine off the plug .

These in a 642 should pretty much eliminate the pre-glow wait. The 648 in the CDI pretty much starts like a gasser anyway. The glow plug light is on for only about a second when cold. Even so, if you go to start it like a gasser it starts right up without stumbling. The same cannot be said about my 602...it'll crank and crank and eventually start coughing and smoking as the plugs heat up.

My 2.5 starts easy. I turn it on, put my seat belt on & then crank. Fires up strait away.

That's exactly what I do

If it's below freezing, I'll let it glow for an extra couple of seconds.

There is a MB technician on the superturbodiesel forum who posted last year May about a new 2009 OM642 having the tips on some of the glow plugs completely gone. He also reported that as he set one of the glow plugs down, the just tip broke right off.

I'm going to bet we are going to hear more about MB ceramic glow plug issues in the future. In the VW TDI world, they've been known to destroy engines.

I have high hopes for the future of ceramics. That said, I don't trust them yet. They shatter too easily and the potential for damage is too great compared to the benefit gained.

Corning had some nice cookware called Visions(tm) that I really liked. Only way to destroy them (it seemed) was to drop and fracture them (or so we thought). Some folks said that the cookware just shattered. Sounds like your typical ceramic to me.

I had a glass top desk that I really liked. Took one of the panes off one day to wash it. Carefully now! After cleaning, gently set it down on the ceramic tile floor. After drying, carefully lovingly picked it up without putting any torque on it whatsoever... shattered into a million pieces! Exploded even.

Ceramics... just don't trust em. YMMV

Mine does too...what I was talking about earlier is what happens if I go straight to cranking it without waiting for the plugs. If I wait 3-4 seconds it'll usually start on the second or third revolution.

Tempered glass has lots of stress. Upset that stress and it'll explode, typically a tap in the right place on an edge or corner will do it. Been there, used to work with tempered glass, have seen it spray 20' across a shop floor from sliding across grit in the packaging.

Yes, there is no chance I would ever put a ceramic glow plug in one of my cars. They are too failure prone. Plus Bosch quit making them for the 04-06 TDIs, leaving those cars with NO drop in replacement glow plug. (The ceramics run at 7 volts not 12)

I will continue to wait a moment for the preglow lamp to go out, then start my car.
