Blanketed Radiators In Winter on diesel trucks

[majorwager]

My MX operates at very low water temps during winter. I added an aftermarket all glass cab with a hot water integral heater. It has an exterior filtration inlet. Unless I cover the radiator, thin sheet metal in front of chaf screen, and cover the exterior cabin fresh air filter, very little heat is prduced by cab heat exchanger. The heating unit ,Ceiling recess mount, has operational recirculation vents which cycle only existing internal cab air. Many of the pre-tier 4 engines operated at lower operating temps.

Manufacturers have some mental blocks about things, I read a sig the other day that said something like "you're overpowered when you burn rubber from one light to the next". When it comes to heat you have too much of it when you have to open all windows @ -20F, or as some might prefer you have to turn down the valve control to 1/4 of lever range. Had a 1980 diesel Rabbit once, we were freezing out butts off in that thing until I got rid of it. I have a Tundra and a Subaru outback now, both of those 'could use' a lot more heat too when the bottom of the windshield gets iced up good and thick or the window glass is seized in ice. I just as soon not talk about the digital approaches, you'd need 40c to address such problems but there isn't a single make that will let you select 40c because some engineer figured that no normal human being would ever want 40c

I gave up on the small radiator idea BTW, at least for now, mostly because I have no room on the sides of the engine where I would have wanted to squeeze them in. Should I later find that I don't ned the stock monster I can always downsize later. According to one Cummins user I might even find that the thermostat never opens while running at 1600 rpm, (nearly full torque).

Well I'm afraid those 2 pics just will not do my friend
You need to do a thread on this project, even if it take's several years :thumbsup:

On your question, even after having diesels in tractors & trucks for ever, I just learned a term here called "wet stacking"
check it out.

*Theoretically* NO diesel should EVER be left idling for more than a few minutes but the entire planet has been idling them for over a century with rare adverse effects :laughing:

I've never experienced wet stacking so far, a.k.a. as cylinder-washing I think where more fuel than oil sprays onto the cylinder walls eventually glazing them (applies to gas engines too). This snow-blower for example is going to run at 12-1600 rpm but the actual load (and resulting torque and work) will be set by the amount of snow and the feed speed. If there's only a few inches then working it hard will not come easy!

As for THE thread I do have an overall 'master' project but it's very hard to keep from confusion with so many sub-subjects involved in it. I think most of my posts on TBN deal with it in some way: "Snow Pump". This re-engining of my existing blower is stage-II of that longer-term three-stage project. I have another 12-valve Cummins that I aim to elevate to 300hp to drive a hydraulic pump on a truck-hosted snow blower as stage-III, in 2019 or more likely in 2020 if the head-office lets me live that long.

Maybe I should name my sub-threads such as "12-valve injection sets [Snow Pump]" to show the parent endeavor...

I remember the "snow pump" thread, but I am visual and I think you had a different avatar then so I didn't put things together.:laughing:

I got the idea last winter I think, just sold the Deutz engine of the original project. THAT project was a thread and a half on Machine Builders Network circa 2008-09! The avatar isn't me, it's a picture of one of Canada's sky-diving grandfathers that I 'took' with a kodak movie brownie glued to my helmet when less than a few dozen people did that sort of thing ...no one had the balls to do the same and take a picture of me when selfies were still unheard of :shocked:

Speaking of radiators, I ran out of room for the belted fan so I'll have to install an electrical one in front of the rad. My son told me to get a shroud or it will neither suck nor blow; he has an airplane so I asked him "where's the shroud around your prop?" :laughing:
