Scania's Ethanol Diesel-Engine, Runs On Biodiesel Too

[social_buttons] Scania (part of Volkswagen) builds modified, heavy-duty diesel engines designed to run on almost pure ethanol (E95, or 95% ethanol, with a 5% ignition improver).

If that sounds weird, that’s because it is. US auto manufacturers make a big deal out of converting cars and trucks to run on ethanol/gasoline blends of up to 85% ethanol. Scania has done better than that for 15 years, and guess what, their engines can run on 100% biodiesel too, without any modification.




Scania’s compression-ignition (CI) ethanol engine is a modified 9-liter diesel with a few modifications. Scania raised the compression ratio from 18:1 to 28:1, added larger fuel injection nozzles, and altered the injection timing. The fuel system also needs different gaskets and filters, and a larger fuel tank since the engine burns 65% to 70% more ethanol than diesel (whoa! see below). The thermal efficiency of the engine is comparable to a diesel, 43% compared to 44%.

While Scania originally introduced this technology for “heavy commercial vehicles in urban operation” (city buses), they’re now extending it to trucks as well. Scania maintains that with existing technology, the transition to renewable fuels can be painless. Since in the last 15 years they’ve put 600 ethanol buses on the road (mostly in Sweden), the company seems to know what it’s talking about.

Scania is also working to develop ethanol refueling infrastructure, which should make it easier for smaller transport companies to invest in ethanol-powered vehicles.

But why not use biodiesel, since ethanol requires about 1.5x more fuel usage? Scania’s answer may raise a few eyebrows: “the farming capacity [for biodiesel] is insufficient for the huge need foreseen for the transport industry.”

Unless you take EU spokesman Michael Mann’s comments seriously (he said that Europe can grow enough fuel to meet 10% of it’s transportation fuel), Scania must be betting on cellulosic ethanol. The intensifying food vs. fuel debate isn’t taking this issue lightly, as I’ve written about here and here.

In any case, Scania’s work seems to indicate it might not be as hard to create engines that run on alternative fuels as auto manufacturers maintain.

  • Trucks on ethanol now? Great. How do we explain it to the 100 million people that are now getting pushed below the breadline? Trucks will use even more food than cars. How does this help?

      To answer ALL of this hubub about the atrocities of converting food into fuel look no further.
      “Algenol’s Direct to Ethanol” converts ethanol from salt water blue green algae while sequestering carbon to feed the algae the algae release in equal parts clean H20 and Ethanol and all of this can be done in deserts far away from any suitable crop land with 0 commercial fertalizers and rather than drain or freshwater resources it adds to them. Did i mention you don’t have to kill and burn the algae after so it is a carbon sequestration process not just carbon “neutral”?

    100 mil below the breadline, so what, their government’s fault for not being able to sustain a reckless population expansion in a competitive world. What do those poor 100 mil contribute anyway but riots and disease? Their land will be settled by more productive people when they are gone. People have been dying of starvation throughout human history and you think because we put people on the moon that it can not happen today. Some of these countries need to take responsibility for themselves if not they should be taken over by people that can run a country. If the voices of the people have decided they want rich countries to stay out of their affairs, it is time they finally listened to and let things play out.

    Dave,

    There is of course a huge problem with over-population in the world. Much of the world are not as educated in this as you or I. Many people have no idea what a condom is or even how to properly wash their hands using a bar of soap. I have seen it first hand. You can’t blame people whose government (other than Zimbabwe) is unable to finance these institutions and provide necessary infrastructure due to lack of revenues from natural resource exploitation (ie. oil) over the last couple of centuries. We can’t all just take what we want like some of us westerners tend to think.

    Ryan, please tell me what party is in power in South Africa. I have a distinct memory that ANC has been calling the shots since the 1990’s. And still if my memory serves me right I remember that ANC is an organization with a strong socialist, and majority rule, agenda. So what has happened? Have the whites managed to get rid of the ANC? When did this happen?

  • Kansas Dave

    Not only dissapointing but comedic how many are just so serious about bashing ethanol and truly do not take any time to learn or read anything for themselves or understand an opportunity when its in front of them. People say raising corn is ineffcient. Do you raise corn? That corn isn’t wasted. Only new this time is that the ethanol potential is extracted from it before its bought as cattle feed. Yes, you heard correctly. Ethanol has had zero impact on the price of food. Why? Because that corn was never going to be eaten by you. Did you also know that ethanol and biodiesel actually make your equiment last longer? No, you didn’t know that either and so would auto manufacterures prefer that you did not know. Remember, its all about big oil and they hate ethanol. In fact, biodiesel plants get unsolicited bids by big petro all the time. These are the only fuels that you can truly stick it to them when you buy them. Food vs. fuel, give me a break. Learn about corn syrup 1st and see if you would agree, you need to use much less unless you already have diabetis?

  • Back to the discussion at hand, Scania should go on and mass produce these ethanol diesels, (or some wise nut should circulate the secrets on pdf on the net for all of us). I come from kenya, sugar factories are dying because locally made sugar isnt competetive against sugar from countries that SUBSIDIZE on their farmers, so, what the heck? why not convert all the sugar factories here to produce ethanol and send out Chevron , BP, Caltex, Oillibya …e.t.c

    im sure the savings in oil importation will more than cover the cost of importing sugar from subsidized farmers.

    – my two cents –

  • good afternoon, chaps!

    here in Finland we do ethanol from waste organic materials, such as wasted/melted food and beverages. Of course that is not much by amounts, but it is still the waste, not away from food to be eaten. My opinion is that all potential substitutes for fossile-fuels should be get considered. We are maintain at the moment to convert the heavy duties to diesel-methane. Also now we are try for also with diesel-ethanol (as now we have knolidge that some bigger are also do so!)

  • Ethanol is the alternative to oil based fuel, that’s af fact. Scania is ahead of the game with their R&D.

    The future of ethanol is not in the corn crop. There are other sources . Crops like sweet sorgum,jerusalem

    artichoke for starters. The sorgum yields about 400to

    500 gallons per acre and jerusalem artichoke 600 to

    1200 gallons per acre. The technology is there we, just need to use it .

  • Jay

    I just want to know how to manufacture ethanol @ home from anything but food. I believe heavily in bio fuels and alcohol based fuels, but not made from food. Two things you should never burn…money or food.

  • I’m currently living in Brazil, the country with the most successful ethanol program in the world. However, as far as heavy-duty vehicles go, ethanol hasn’t been so much used as in light vehicles. Back here it’s still easier to see the ethanol being used in blends with the regular Diesel fuel only at sugarcane farms and sugar/ethanol factories, and there were even a few trucks and tractors that used ethanol on compression-ignition engines without any ignition improver but the cost of this conversion was quite high…
