On diesel and gasoline automobiles.

I will get a new used car soon, and am torn on an old diesel 1973 Mercedes and a gasoline 1985 Volvo sedan. A diesel to me is obviously better: more torque, easier to repair, lasts long, but I live in Vermont. And in Vermont, diesel turns to jelly, but I am prepared to deal with it. A gasoline engine, on the other hand, is faster, not what I need, and has less torque. It also stays good in the cold. I would turn the diesel into a veggie, to me that is a great benefit. The thing that keeps me from the diesel Mercedes is the law, you can't by a new diesel, and I can't find where it says I can't by a used diesel. Also, how hard would it be for me to convert to veggie, to get veggie fuel, clean it, and to heat the fuel for winter? There are many diesel stations just sitting around where I live, so that is always an option. Why do I even ask? Because a gasoline would be so much more convenient for me. A Volvo is a perfect choice if I want an easy to use, get up and go car. A Diesel would make me wait for a couple of minutes before I go anywhere. Of course, the final decision of the car I will buy will be totally remodeled into a newly painted, shnaztastic, car with all the means to repair on the road. When I start this summer, I will keep you posted, every step of the way. Post a comment or email me at Stephendanielalverez@gmail.com

Can diesel be separated from petrol?

​this is a reply to my last question as for some strange reason I can't reply and leave a comment to the thread. ok thanks to those replies,  I am in oz and the reason I've asked is due to free diesel that has been contaminated with petrol being offered to myself. So, given I have free fuel I am prepared to treat, separate, spend some $ on in trying to produce diesel and petrol separate. I have looked at a continuous separation distill unit but I don't know how it works and the safety factor, don't want to make a bomb! Other ideas are leave the diesel out in sun and evaporate petrol(not so good for environment and water getting in diesel) or add oil to mix. Most of the fuel mix is majority petrol and minority diesel, although exact ratios are unknown. I have run my lawn mower on it quite well so given that it is mostly petrol, can I either;1. Add more petrol pure to further dilute the diesel. 2. Add an octane booster to over come the diesel influence. And specific comments and answers appreciated

Diesel/petrol mix in old engine?

I can't seem to respond to messages on answers? Help admin?  ​thanks cyber for you comprehensive answers. I have since put in hi octane fuel as my car started running bad and then stopped due to, I believe, the diesel sitting in the bottom of the tank and now being the majority fuel source. The hi octane fuel got me going but only at idle speed, no acceleration. I got home. It's like it floods when I try to accelerate from un burnt diesel. According to your post above, hi octane fuel makes it worse. I will drain and leve for lawn mower, which works well. That bring me to another possible use. An old engine,carby with not cat converter and 10percent diesel? Yeah I know, give it up. I guess what I would really be happy with is, what can I use a diesel/ petrol mix fuel for?

Bio-Diesel production by products, what do you do with them?

I have seen some folks hawking their books for DIY Home Made Bio-Diesel.  Ok, it can be done but what do you do with the byproducts, i.e. the initial sluge produced when titrating the primary oil with lye, then washing the resulting oil with water to titrate out the soap?  It seems to me a lot of work and mess to deal with.

Belarus Tractors-cold weather starting information?

Thank you for taking my question.  I purchased a Belarus tractor model 525 (65 hp. 4wd) new in 1990.  Although the tractor came equipped with glow plugs, they burned out shortly after I purchased the tractor.  I replaced the glow plugs again and they also didn't last long.  I then installed a block heater which heats the water and also a small heater from Wolverine company which actually glues on externally to the bottom of the oil pan.  Now although these products help somewhat, I was wondering if any of my good Instructable friends have had similar problems with these types of tractors and how they eliminated the problem.  The two heater items while they help, require several hours if not overnight to work.  Other than the cold weather starting problem this has been a good solid tractor.  In closing, I know these tractors are made in Belarus/Russia where the temps are far more severe than here in Southeast Missouri so I know there must be a solution.  One last thought, cold weather for these tractors is defined as any temp. below 60 degrees F.  Thanks, Debra Kay

Petrol/diesel still separator

Ok so is any one game to make a basic still that will evaporate petrol into vapor and then reform via cooling into petrol? Where a vehicle that runs on diesel has been filled with petrol, this device could save $1000's. No spark or naked flame to a 100 degree max temp will be safe. there's a challenge! PS garages will give you this stuff for free.

Can a diesel run on 2stroke fuel/be supplemented with 2 stroke fuel mix? Answered

Hi all can a diesel run on 2stroke fuel mix if the 2stroke oil was added to the petrol in heavy enough quantities so that 1. It off set the octane rating of the petrol so that it acted like diesel? 2. It was blended with diesel to supplement the mix?  The reason I ask is that there is a lot of mistakes made at the fuel pump with people putting fuel in diesel and I was wondering if the petrol was know, that a measured amount of 2stroke oil was added that this would solve the problem, rather than the expensive issue of towing, draining and repairs? I have had this experience and drained most of the petrol and then added motor oil to the new diesel to help lubricate and no dramas. Positive comments please.

Scottish Island Stays off Grid - replaces diesels with 95% Green resources.

The Scottish island of Eigg (pronounced "Egg") has never had mains electricity, and has had to rely in expensive diesel generators for the power they do use.Devices that require 24/7 supplies, such as fridges, have been an unknown luxury.Today, though, that all changes:A renewable energy supply giving the Isle of Eigg power 24-hours-a-day has come online for the first time.The £1.6m system for the island in the Small Isles between Skye and the Ardnamurchan peninsula uses a mix of hydro, wind and solar power.It has been designed to generate more than 95% of Eigg's annual energy demand and is backed up by a battery storage system and two diesel generators.Residents have previously relied on diesel generators and hydro schemes.The dream of green power has taken 10 years to realise. A total of 45 households, 20 businesses and six community buildings on the island are linked together by six miles of buried cable that forms a high voltage network.The whole project was organised by the community themselves - at the switch-on ceremony (in the local tea shop), the island's children gathered round a candle-lit map of the island and blew the candles out as the power came on.Before the switch-on:homes were powered by diesel, wind or hydro-generatorselectricity was unreliable and restricted to certain hourssome residents went without washing machines and vacuum cleanersthe noise from the generators could be heard for milesDiesel was delivered by boat but services sometimes cancelledBBC News storyBBC Magazine article, with comments.

How to obtain used cooking oil from a fast food restaurant.

With today's rising fuel costs, and the promise of homemade or readily available "biodiesel" for diesel engines, I was wondering if someone could make an instructable on how to get used cooking oil from a restaurant- most likely of the fast food variety. Used cooking oil is in excess in these restaurants yet it is a valuable resource to be recycled in diesel engines.

DIY Plug-In Hybrid Pickup Truck

Hi everyone, For a while, I've had this as my "back-burner" project. I'm trying to really get going on it now. It's an Open Source, DIY, Plug-in Diesel/Electric Hybrid Pickup truck. That's really a mouthful, so I'm just calling it the "SuperTruck" project, until I can come up with a better name. The entire concept is that it is a parallel hybrid, which you can charge from the wall, and it has a diesel engine that can run on diesel, bio-diesel, and possibly veggie oil. Either the engine OR forklift motor will be able to propel the vehicle. (Meaning that it will have a dedicated EV mode.) The driver can manually decide to run it on diesel, electric, or both depending on the driving situation. The mechanicals are relatively simple. It uses a manual transmission (rather than a CVT or planetary gearing.) In theory, this will be a project than any advanced grease monkey will be able to duplicate. I'm not much of a car guy, but I have learned quite a bit working on my electric motorcycle, electric car, and experimenting with running my car as a hybrid. Here's a YouTube playlist of what I've got going so far. For the latest on this project, please visit the page for it on my blog: http://300mpg.org/projects/supertruck/ I'll definately need help on this project, so please tell all your friends about it!

Why does an internal combustion engine have to run on liquid fuel?

I have a full knowledge of how petrol and diesel engines work so I know that it is far easier to get a liquid fuel into the combustion space than it would be a solid fuel. However this does not mean that that it would be impossible to introduce a solid chemical fuel broken down into a light powder. The problems would be to identify a suitable fuel and its costs. It would obviously be necessary to dispose of combustion by-products with minimal polluting effects. Does anyone have thoughts on this or do you think its a non starter? I would appreciate any thoughts. Bean
