Turning a HUGE van into a hypermiling house!
Hello all!
Followed the forums for a long time (despite never having owned a vehicle before) Finally i have purchased my first "car" a Long wheel base, high top, Iveco Daily mk3 (35s13v) 2.8TD van from 2000! If you were to design the worst aerodynamic frontal area possible, you would design this van! My plans might be a little bit different from other builds as I am trying to improve the efficiency both as a vehicle and a home. for example using coolant to heat hot water when engine temperature is high. an early goal is 10L/100km consistant longer term goal 8L/100km Initial plans are: Running on vegetable oil - i will be running on used vegetable oil using a two tank system. vegetable oil has less energy than diesel unfortunately, but is free from my work or very cheap if i collect from other places. i don't care about any downsides to this as i will only drive a carbon neutral vehicle (i'm aware of the embodied carbon and other environmental problems cased by driving). This is just a personal choice. Scangauge or cheap bluetooth OBD reader alternator delete - power from 48v house battery with DC-DC step down experiment with front grill blocking - air conditioning delete - possibly install 48v electric motor on compressor to use as AC for the home EU "A rated" van tyres - similar to Continental VanContact Eco, maybe up the diameter to increase gearing and if possible narrower Total belly pan - maybe it will also help protect against corrosion? Electric radiator fan - Install rooftop solar - the roof has space for 4x 350w sunpower PV panels so 1.4kw maximum when i can afford it. this will affect aerodynamics but will replace alternator and possibly AC Engine preheater - running from house battery and external when needed Be weight conscious when build the living area - With a very heavy un-aerodynamic box - DRIVE SLOW! And any other suggestions you have for me! Thanks for reading and thanks for making this forum a fantastic online resource! https://upload.wikimedia.org/wikiped..._2.3_Front.jpg (not mine but same size) |

Big side mirrors could be replaced by smaller ones. And how many tires you have on the rear axle, 4? You could leave out 2. |

i did think about exhaust heat recovery but wasn't sure how to go about it as, unlike the coolant, we are now talking about temperatures above the boiling point of water. I don't know anything about water injection! i will look into it, it sounds very interesting! I don't know a lot about motor-generators but i read this very interesting page: https://efficiencywins.nexperia.com/...generator.html It would be amazing installing one on the driveshaft and having some motor assistance and regen! seems like it'll be expensive but i will look at what i can find! Yea i did find some rooftop AC units but i'm not too interested in adding more height to the van and the new ones are incredibly expensive. my other thought was a portable unit with the ducting exiting through the floor. I agree on the belly-pan. but if i can get some cheap corro-plast i might try it and test it at some point. Thanks again for your input! |
