Little Diesels

 Small, Economical Diesel Engines

I know, I know, nothing new but have you seen Fiat's Multi-Jet Engines? They're in "cahoots" with GM now, why can't we get one in a Cavalier or a Sunfire. In fact the only small diesel you can get in a small car in the US is Volkswagen's TDI, and you can't get one of those for under 15 grand. Also, wouldn't a little diesel work great with GM's VDi Transaxle. I'd settle for the 5-Speed though. Is anybody with me?

       This is not an idea, it's a suggestion. Please read the help file again, or for the first time.

       Coming to a Jeep Liberty near you. Diesels will make a comeback in a few years when low-sulfur fuel is more available.

       If that's true, I hope they are able to do something about the particulates that diesels emit. They are particularly vexing. Of course, the micronized and nanotized particles being created for competitive absorbers is becoming an issue as well. Especially sunscreen.

       The Liberty diesel currently cannot meet the emmissions standards for 2007. It my be short lived.

       When the petrol runs out in 20 years, bio diesel will suddenly become very popular. Buy a diesel car now and future proof your driving. And it means your car will smell like a chip shop.

       Buy an _old_ diesel. Modern designs won't run on biodiesel.

       What is the problem with biodiesel in new cars?
—Belfry, Dec 03 2004
   

       I dont think it will be a problem with processed biodiesel, but straight filtered veggie oil works best with inline or jerk pumps, not rotary. Veggie is too thick for this type of pump. I'm currently working on a couple of test with veggie oil. One, simply comparing Pto output on a Kubota tractor when its run with diesel and then run with veggie. Further testing will involve temperature requirements of both the engine and veggie oil. The second involves two brand new Kubota 2 cylinders. I will run 1 on veggie and the other on diesel. Run both for 100 hours (measuring fuel consumption along the way), and then tear both down to see any physical differences internally i.e. gumming, deposits, wear, etc. I'll keep folks posted as to what I find. Also a friend has a bus that he has been running on veggie. He is retiring that bus to begin another. Ihope to get that engine for inspection.

       For old, read simple. An up to date turbodiesel will freak if you put biodiesel through it. One reason is that the fuel is oxygenated, so the "water in fuel" light will come on. There are others, to do with the ECU's programming. Nothing insurmountable, but don't just pour it in and hope.

       What about spark ignition engines (ie petrol stylee) and bio fuels?
—Belfry, Dec 06 2004
   

       Same as running diesel in your gas engine. May be able to add as a blend, but the difficulty will be in straining. The old two fuel (gas and a tractor fuel, like kerosene) tractors were started on gas, the radiator shuttered off to increase engine temp, and then switched to tractor fuel. Heaven help thepoor guy that shut the tractor off before switching back to gas.   

       What specifically are you calling 'biodiesel'?
—bammer, Dec 06 2004
   

       I don't know what it is, I just know that you can buy it down the road from my house. I presumed you could just stick it in the tank of a diesel vehicle and bob would be your uncle.
—Belfry, Dec 06 2004
   

       That is probably a 20% blend (B20). If I remember right,straight biodiesel is made by mixing a catalyst with ethanol. This is then mixed with a vegetable oil. Some heat is added, but easily can be solar. After a short period of time, a day or so, seperation occurs. Biodiesel to the top and gycerolto the bottom. The biodiesl can be syphoned off for use. In a nutshell, but not quite as easy. This has better lubrication than petroleum diesel which adds sulfur for lubriction. The experiments I am doing involve vegetable oil straight from McDonalds. Pure waste.
