In search of a glow-plug for my S1100

[Henry W]

All considered, I believe I would try the intake heater first, at the very least. There would be less irreversible changes made anyway.
there is not a lot to the darn things, as you can see, the pic is of one off a Cummins 5.9.

That would work real good on a Changfa type engine.

Henry:

the first one you listed from ebay, is just like the one cummins used to use years ago on their 855cu/in engines, they
used a hand pumped fuel pump to squirt fuel into the intake over the heater making like a flame thrower down the intake

worked very well.

for a changfa it just looks pretty easy just to drill and tap the oem plug and fit it with a 6.9 pencil unit, and control it with a
micro controller prior to startup or energize it while the engine is cranking

the pencil tip is down  near the injector spray anyway, and i believe that is how the thing works to provide ignition

the 6.9 pencil units are less than 7 or 8 bucks each if you shop them out.

thats the way i am going to go, but i will be activating and controlling them with pulses from the controller prior to startup

its just too easy to do otherwise.

i am not big on the idea of an intake heater in a single cylinder engine that has some rather harsh vibrations and intake pulses
for fear of eventual breakage of the heater tip and having bits and pieces ingested into the engine.

ymmv guys

Bob,

You know you might be on somthing. there has to be thin pencil tiype glow plugs. If there is enough meat on the oem plug and it can be chucked in a lathe and bored and tapped that would be the way to go.

I wonder if Mityvac has a glow Plug adaptor that will fit. What I was thinking is they might know someone that can make a adaptor.

Just a thought.

Here are a couple intake heaters that are on ebay.

This is the same unit used on the old Perkins. Just hook a 1 gal. day tank,  gravity fed, and a fuel hose to the heater. Then wire it to a momentary switch and fuse 20 amps. Hold the switch down, as it heats up, the thermocouple opens and lets the heated fuel drip into the intake. Varooommm.....she's off and running...Ive started, at 10 degrees F, about the same cranking time as 60 degrees...no heat. mine have been installed since 1964, absolutely never leak down, when not energized. It's a most simple solution, and effective.

Now that is cool. I did not know it had a fitting to hook up a fuel line when I posted it. Now thinking about it I remember seeing somthing like this on a jeep CJ-5 with a perkins diesel back in 1986. It was cold out the person pushed a momentary switch for a while we heard a poof sound and he cranked it over and it was running. I wonder if it is the same thing.

Does it use gasoline or diesel ? Does the fuel line in the unit on Ebay hook to the 3/8" thread at the back ?
Would you be cranking the engine and then activate this unit or would you first activate this unit and then crank the engine after a bit of delay? How long does it take for this thing to light off ?

Hi Jens,

Yes the fuel line hooks to the 3/8 thread. Hold the momentary switch prior to cranking, it takes about 15 sec to heat the thermocouple to open and let the fuel flow, then continue to hold for another 20-30 sec. depending on how cold, and how well the engine normally fires, while continuing to  hold, start cranking, a couple of hits and misses and she's running.

I wouldn't use anything but oil, a gas engines would be a true danger in my opinion.

Henry it is the same thing, Perkins didn't start using glow plugs until the tier emissions came on scene. On marine units they have a key switch, that has a position to the left that is used to energize the thermocouple...you turn the key left for 30-120 sec. temp depending, then turn the key right to cranking. I've found that they start much easier, and faster if you continue the thermocouple while cranking. It just means a 2 handed start...like many gensets...that use glowplugs.

I've managed to find a Chinese manufacturer who will make some glow-plugs specifically for the S1100/S195 engines. Unfortunately their minimum order quantity is 1000, which means that it is not a viable solution for me. I haven't got a quote from them yet, but even if it is $5 per plug I would never recoup the investment - IDIs are not as popular as DIs these days, for obvious reasons.

I contacted the local Helicoil specialist and they recommend that I use a hand reamer rather than a drill. I've ordered the necessary tools, so will let you know how I get on.
