Making Engines Run on Vegetable Oil

Diesel engines might not be the first thing you think of when you hear the term ‘low emissions’, but Audi is on a mission to change that and keep the internal combustion engine alive a little bit longer.
Audi has approved some of their V6 diesel engines to run on vegetable oil. Not diesel. Not petrol. Vegetable oil.
It’s a biofuel called Hydrotreated Vegetable Oil, and they reckon it will result in a 70-95% reduction in co2 emissions.
It almost sounds too good to be true. So, what is HVO, why is it so good and is it the future for diesel? Let’s get into it.
It’s worth noting that people have been running old diesels on waste vegetable oil for quite some time now. You can trawl through all the different forum threads from people asking if they can run their car on old chip fat.
It just makes sense. Who wouldn’t want a renewable fuel that’s cheaper than the stuff you get from the pump? You could use the cooking oil from last night’s dinner to get you to work.
In theory, any diesel will be able to use vegetable oil. After all, the inventor of the diesel engine, Rudolph Diesel, actually ran his early engines on peanut oil.
Unfortunately, it’s not quite that simple.

Years back I had a Volkswagen Polo 1.9 SDI. I used vegetable oil in that car for many 1000s of km's. Never had any issue. In colder weather I used a mixture of 70% oil and 30% diesel However, the last 7 years or so, vegetable oil became as expensive as diesel, so it's not worth it anymore

IMO: 1) setting up new HVO places is relativelly easy, especially when compared to building a new charging station or a hydrogen fill pump - we can use the *existing* infrastructure, just replace the diesel in the tanks with HVO and maybe some HVO rated pumps, hoses and whatnot. 2) manufacturers should take a deep dive and give us comprehensive list on which engines can be run on HVO without modification, which require some modification and which are straight up unsuitable for HVO. If I could just look up on the internet what I need to do to safely run on this stuff (and the stuff was reasonably priced), I wouldn't hesitate filling up with it. *This comprehensive list should take into account all older engines with significiant presence in Europe* - such as the 1997-2010 (roughly) 1.9 TDIs, which are absolute durability beasts and will run for eternity (if well maintained ofc)

Another problem with anything plant based is that it will displace agriculture. Traditional diesel doesn't compete with bread for example, but every plant based fuel does, which drives the pricess of food up.

[@PepperSnek]

I remeber reading an article on McDonalds and how they process their cooking oil. I wonder how much of their diesel consumption is covered by cooking oil. Also would be interesting to know how much waste oil do all the restaurant in the world produce per year. Even if you could cut the diesel usage by 20-30% globally that would be a huge success.

[@kooooons]

Well... Animal based food can use up to ten times the agricultural land so if anything, biofuels compete with steaks, rather than bread. The fun part is: most plants suitable for biofuels are actually pretty inefficient in using sunlight. Using wind and solar to produce hydrogen might be more efficient especially since solar also works on rooftops, while tractors on rooftops might be frowned upon :D

[@DocWolph]

@@kooooons Be more honest. Plants in general are "pretty inefficient at using sunlight", which are on average on 5.4% efficient. But then compared to what? Solar panels. They do average about 20%. But even a car covered almost entirely with Solar panel can not make a BEV fully free of even the grid. The energy density of Liquid fuel is orders of magnitude greater than what can be stored in batteries... and decidedly safer in higher quantities. Gasoline rates at 45MJ/Kg or 36.6 Kwh/gal. Diesel rates at about 40MJ/Kg or 40.7Kwh/gal. It only comes down to how that fuel is generated and used. The current applications of current ICE engines will not work out well overall. But it is overtly possible to reach at least 100mpg(US) with said engines and applications. However more advanced engines, such as the Astron Aerospace Omega 1, read as being able to reach 3.0mi/kwh (101.1mpg) to having potentials to reach energy efficiencies as much as 6.0mi/Kwh (202.2mpg). Such engines will not be driving the wheels but a generator.

Synthetic fuel is quite possibly the best solution ever made and will definitely save humanity. ICE cars are very low carbon to produce or even free if you’re continuing to use a old car that used to run on normal gas or diesel.

For almost the entirety of Earth's history atmospheric CO2 concentrations have followed the global average temperature with a lag of hundreds to thousands of years when CO2 concentrations have continued to rise while the temperature fell and vice versa. Even the current warming, which began before the industrial era creating the conditions for mass industrialisation to occur, has been followed by the rise in CO2 we have witnessed, the vast majority of which is from natural sources.

For example you burn 1l and make 3l, there is a 2l net gain. The co2 emitted is from burning that 1l . so 67% reduction in emissions for this ratio but in reality the ratio may be worse. the 3l that you burn have zero co2 impact because the planted captured the exact quantity of co2 before.

The diesel engine was originally designed to run on peanut or vegetable oils. It was only pressure from the fossil fuel industries to have manufactures use their oils. Plant oils have good lubricating and combustive properties, the only issue really is the injection systems designed for fossil fuels struggle with the thicker plant oils. The diesel engine is very efficient and only polutes due to the fuels used and taxed by our governments. There lies the issue, government taxation. Politicization of what we are allowed to burn. Waste plant oils are a readily available source of fuel, specifically from restaurants and bars, and solves a disposal problem , but governments put every obstacle possible in your way to discourage you using waste vegetable oils.

Interesting idea I heard a long time ago in Cuba bcuz of the American embargo Cuban cars r dual fuel petrol to start & warm the motor & then switch to diesel I don't know if it's an urban myth but it's good there is still a place for internal combustion !

[@jonntischnabel]

Makes me laugh that it's being made to sound "revolutionary" when diesel engines have always ran on vegetable oil! 😂

[@alexmat106]

Maybe they don't allow HVO for high power output because it's less energy dense and will need more fuel flow rate for the same performance, thus stressing fuel pumps etc. Might also be because they don't want to offer higher power output diesel engines anymore...

[@gordie4059]

I hope this ages better than the ‘Flex Fuel/Ethanol’ movement for gasoline did in North America. It never makes sense to convert usable farmland to make fuel rather than food. Also, ethanol in gas vehicles proved to be a failure for multiple reasons. Engines fuel systems gummed up over time and vehicles ran like crap etc. Plenty of videos out there now explaining why. We need large scale HDPE plastic distilleries to make usable fuels from all the plastic floating around in our oceans! That should be high priority. HVO sounds awesome, but it should ONLY come from recycled vegetable oil & animal fats. Fun fact: In Canada there are lots of city buses that have been converted to run on ‘veg oil’ and those buses run everyday in plus 30 to minus 30. It can be done.

[@jakedcrane8019]

Humans dont it corn, farm animals eat corn. What anti-ethanol fuel groups dont tell you. The corn is basically split to multiple parts, one goes to fuel and second part goes to animal feed. its not like corn gets competely produced to fuel. You should look more at the actual corn ethanol production rather than watching BS studies.

i currently run my VW Caravelle 1999 2.4D an old audi 100 engine from the late 70'ties on waste vegetable oil it cost around 1.5usd per gallon in Denmark where i live the diesel cost aroun 2.2 dollar per liter or 8-9usd per gallon

[@seanjuth]

I guess I can post it here so it's easy to understand: Diesel engines were invented to run on homegrown vegetable oil. Petroleum diesel fuel itself is an oil. Using vegetable oil as fuel In a newer diesel engine with a common rail fuel system that's high pressure, it's not a very good idea. If you have an older diesel that is mechanically fuel injected, and it's not cold outside, by all means use it

My BMW 535d 2012 runs on HVO100 even though it "can't" or it not supported yet. The funny thing is that it starts and runs better with HVO all year round. I know a technician that builded himself a generator, a twostroke detroit truckdiesel engine. That generator runs on HVO and he can store the fuel for unlimited time while today's petroleum diesel (1st gen renewable fuel) has problem with storage because of microorganisms in the RME mixture. RME was a failure, the second gen renewable fuel HVO100 is much smarter, a synthetic copy of real 100% petroleum diesel. That's why I'm confident using it in my car.

The bigger issue is more rain forest will be burnt down to create farming area to produce the extra oil needed. This really can only work if using recycled vegetable oil and thats always going to be mean its going to be extremely niche.

Well, they pretty much solve it. They bioengineered the palm oil to be short, but still produce the same amount, use less space and add more palm.

Vegetable oil is not necessarily less polluting than fossil fuel. 1. Vegetable oils require fertilizer which take energy to make and transport. 2 extracting Vegetable oil takes energy and is labor intensive 3. The distribution 🚚 of oil to pump location takes energy. 4. Vegetable oil need to be heated before it can combust .

I thought the major emissions problem with Diesel was not so much CO2 (of which I think it produces less than petrol), but that it produces more NO2 (mainly). How does HVO and these Audi engines handle that? Or don't they?

[@The.world.has.gone.crazy...]

@@jeanackle a modern day diesel car in Europe has filters in the exhoust system that filter 99% of all particles that pass the exhoust system. The air comming out the exhoust is cleaner than the air sucked in the engine. Look up euro 6 diesel norm. Its by law in all european countrys. The system also sends part of the exhoust fumes back in the engine for extra combustion to burn extra particles. Only downside is the price of the filter that has to be exchanged at a set kilometers, so some people dont change them or cut them out and weld a pipe in.

There is a confusion between the difficulty in ignition, and the tendency of fuel forming wax/gel in cold weather. They are two different problems. Ignition quality is defined by cetane number. Higher the cetane number, the easier a fuel auto ignites. Cold flow quality may be described by CFPP. You mention that HVO has a lower CFPP than petroleum diesel, which means a fuel can flow in cold weather without wax/gel plugging a filter. This does not mean that HVO can ignite more readily in a diesel engine.

Vegetable oil for engines and lubricating machinery. BUT is promoted by most governments as a healthy alternative to cook rather than use animal fats ...

the station is no much of a problem, any station might start selling it as is and then with all the stuff happening right now that 10% price increase would still be cheaper than current diesel prices and it could be subsidized a bit

I ran a 2.4 PD VW engine on pure veg oil. It started from cold with no issue and ran okay. Problem is veg oil has a low cetane number, much lower than diesel and although it pulled reasonably well was down on power and did less mpg. Veg oil will soon block a DPF and ruin a catalytic converter. Veg oil will wreck most common rail diesels with the rotary pump blowing its seals. A better idea though than electric vehicles where pollution is at the power stations rather than the exhaust. Electric vehicles are pretty much useless for distance driving anyway. The range is just not there and with charging taking so long would make a 4hr journey into a 6 to 8hr one..

About time too, none of the later VW/Audi/Skoda/Seat engines will run on biodiesel because of incompatibility with the rubbers and plastics used in the fuel system. And before some pedant jumps on me, yes I know Hydrotreated Vegetable Oil is not the same as biodiesel made by transesterification.
