Diesel Flame Heater Tech Discussions

Researching Diesel Flame Heater Systems.

In summary the system produces a small flame in the inlet system that sends hot air into the inlet manifold for cold starting.
These systems were used on many tractors and industrial engines as well as a number of European Trucks like the Iveco Daily and perhaps even the Santana PS-10 Land Rover.

Have included a picture of the plug.
Am not sure, but think that diesel is pumped into the center of the Glow Plug Igniter where fuel is metered through the center when energized with 12V.
The fuel passes out where it contacts a red hot coil that creates a flame.

Does this sound right?

Intake Manifold Flame Heater System

doesn't get THAT cold round here though. I wonder how helpful this would be in local temperatures

I think before I think about this, I will have to invest in a diesel CAB heater. I do like the idea of ruggedizing capabilities. even when it does add failure points.. Like old water injection systems or even methanol injection... go out to start your car one day and it's hydro-locked.

looks like they're a big item currently on commercial trucks to diesel pickups... any heavy equipment. Lots of variations. Interesting to research. I assume there's a relay hooked up to a thermistor /stat to tell it to shut off.

Thanks.

Am looking for a more simple solution than the one with 20 different parts and will probably use a timer setup.
Looks like testing the plug we have is in order...

I don't quite understand the "20 different parts" thing.. What I was reading. Older systems had a reservoir system that allowed fuel to drip onto the element. Looks like newer ones like pictured use a fuel pump to atomize. Doesn't look like they have any pressure based or electric injection to them, just a nozzle. Solenoid fuel switch. Used as a pre-heat of the intake vice what i was thinking, a heating of the intake air for the first bit. The electric grids are more of the running engine heater? W/e I should be working. Looks like on tractors they had a button "press for 45 seconds" type of thing.

that borg warner one does have a "fuel metering device" in it. Wonder if that's a pressure "switch".


From an IH forum...

Robert, not so much of a flame but the heater creates a vapor, had the same in my Daihatsu 2.8.it was all controlled by a 12volt timer/temp

This looks so much simpler and doable.
Thanks... will use this as a guide.
I think the metering is built into the glow plug device

I have a bunch of those Diahatsu 2.8 TDs.
They go well in a series.
Never knew they had this setup.
Will closely examine the inlet manifold of one in the shop.
