That old idea of using exhaust heat
September 13, 2010 - 11:26am
So check this new Lexus out:
The thing which really caught my eye was the new exhaust heat recirculation system which routes coolant to the exhaust in order to speed warm-up in the winter. Now if only I could design an aftermarket simple version to speed my warm-up time...

Ha! Yea, I don't think I have the knowhow to scavenge the heat without screwing up and boiling off the coolant.
Pretty good, car is at 165K since I stopped my crazy driving schedule. Still mint. Got my PV array installed, 7kW, so now the specter of getting a Volt will grow. Not keen on the Leaf only because I'm in the country and 100 mile range is nothing. Can't even make it down to the city on one charge. So maybe next year at this time I'll be sporting a new Volt. Or, I'll get right up to the point of pulling the trigger, only to smack myself and ask why it was I wanted to spend $35K when I have a perfectly good car that costs almost nothing to operate already? :-)
How's things on your end, did you go to Greasestock this year?

Unfortunately, I was not feeling well when Grease Stock came around. No, I did not make it this year. Other than that, I have been busy improving my filtration system(s) and currently, I have 1,000 gallons of filtered grease down to 5-microns. My outdoor time is just around the corner. I have several trips planned. This should allow me the opportunity to use up a good portion my filtered grease. I have 4-plastic (275-galllon) totes full. I either have to use more grease or acquire several more totes! It is a good thing I have the room for all of this crap, or my wife would be riding me like Sea Biscuit!
Well, off to work I go!
Take care of yourself

Slate... if you need help getting rid of excess oil... let me know. I'm always happy to grab some extra.
Where in MD are you located? I'm in Bmore.
I have had the exhaust idea for many years. Just don't really have the time, space, or tools to tinker to that degree. I thought about running a closed loop liquid system around the pipe that coiled up either into or around the WVO tank. I just think that the end of the pipe takes too long to heat up to make it worth it.

Chase - Install a higher temp thermostat; add a MB aux water pump to push the coolant water back to the in-tank heat exchanger, add a 16 plate FPHE as close to the fuel solenoid. From a cold engine and with 40F morning temps, I switch over to VO in 4 to 5 miles with the engine temp at 175F and still climbing to 190F.

Wait, you are talking about a system to use exhaust heat? If so, can you describe the actual contact point of the system to the exhaust? Also, how do you avoid boiling off the coolant that remains closest to the pipe, the pipe should be well into the 400F range.
