Super fast warm up mod - Engine insulation

[slowmover]

There are engine oil heat exchangers mounted at the oil filter inlet to hasten engine oil warm-up and to keep temps from spiking while underway (working hard or hard conditions). This is from a police-spec Ford, and here is a diagram from a Chevrolet.

MOPAR used to sell one that was simply a block filter adaptor with two lines for coolant ingress/egress, and ran to radiator and from the water pump. Used on early V6 minivans. Looked like this.

Is this for the prius? I insulated mine a year ago including a belly pan. It works quite well if you seal the hood properly with weather stripping. The best deal is the super thick pickup truck bed cover seal. For the bulk of the job I was very lucky and found a few sheets of 1inch engine bay sound insulation with the reflective foil on it. It just sits on top of the engine and can be removed easily for maintenance.

As for quick engine heating one possibility is running the exhaust pipe throughout the engine compartment. Not an easy task but with some bypass valves it would be simpler than heat exchangers.

One thought I had, when not near an outlet ,was powering the tank heater from the battery but I'm not sure the math works. Also, where do you get a 300 - 110 volt converter?

Could that be the effect of engine cooling? Have you noted the coolant temps at startup in the morning and afternoon?

Hmmm, I'd say its probably not a real large factor. With the block heater on the Prius, its about 90F when I start it in the morning. When I leave from work, the thermos is still pretty warm and the engine is at roughly 80F as soon as the engine kicks on.

When I started this thread, the intention was to insulate the Paseo's engine. The Prius could definitely benefit from faster warm up though.

Do you have any pictures of your insulation job?

Doax,

Whenever I see a thread about insulating the ICE for better performance,
Randall's Insight comes immediately to mind. The ICE is completely covered
and has imbedded temp sensors.

A sight to behold!

This shows what is achievable... well, at least by some... or by one.

Read more about Randall's Insight.

(This has been posted before, but it's so spot-on for what you're thinking
about it deserves a fresh airing.)

Hi,

I tried to make some kind of grill cover for winter comutes to my job (I drive 8 miles to my work). I wanted the diesel engine to warm up a litle bit faster and save/insulate some heet during short stops.

I left one space opened, to let some air cool the turbo's intercooler.

The car is Opel Astra, 1,9 l diesel engine

PS: unfortunately I can not post the images, not enough posts

I did this a while back: http://ecomodder.com/forum/showthrea...ids-21241.html

I "feel" i have faster warmup and i "think" i get slightly better mileage... (YMMV)

unfortunately it seems, that I have a thermostat problem, probably will have to change it...

But than I should get the engine warm even faster

Has anybody tried insulating the fenders? I would imagine that some expanding foam in the fenders would help retain a lot of heat.
