does vegtable oil give off greenhouse gasses when used to power a deisel car?

Question

ive learnt that vegtable oil can be used in your deisel car but is it cheaper and better for the environment?

Answer 1

Yes

Answer 2

Yes it does give off greenhouse gases, such as carbon dioxide.
But here is the important bit - an equal amount of carbon dioxide was absorbed by the plants from which the oil was made. So the overall it doesn't add to the problem. This is a big improvement on using mineral oil.
Biodiesel is an organic fuel made from plant or animal fats. It is very similar to cooking oil. Properly processed Biodiesel can usually go straight into a diesel engine without any need to modify the engine. A diesel engine can run on Biodiesel or regular diesel or any mix of the two. Biodiesel is usually made from waste oils although dedicated fuel crops are also an option. Engine specialists are enthusiastic about it. Its properties as a fuel are superior compared to mineral fuels both in terms of how environmentally friendly it is and how well engines perform using it.

There is a Europe-wide standard now applied to Biodiesel to ensure that quality is consistent. This quality assurance enables car manufacturers to approve its use too. The standard is EN14214 and unless you know the producer, it is best to insist on having fuel with that specification.

Answer 3

As others have said, biodiesel gives off the same greenhouse gases as regular petroleum based diesel. The amounts emitted are approximately equal, but the CO2 from biodiesel is derived from carbon that was fixed by the plants or animals that produced the fats used to make the biodiesel. So, these emissions are essentially carbon neutral. But, energy was used to grow the crops, to harvest them and to bring them to market (or to collect the waste fats). Energy was also used to convert the fats to biodiesel. Additionally, fertilizer was probably used to grow the crops (oil seeds) or the feed used to fatten up the animals and the production of this fertilizer also resulted in the release of CO2 both from the process itself and from the energy required to make the fertilizer. So the net greenhouse gases emitted is still possitive.

Answer 4

Not as such, all fuels when burnt leave a trace, however, veggy is nowhere near as bad, and in fact if you add straight veggy to diesel you reduce the carbon dramatically.
The french add 2% anyway but up to 20% is very good and on old diesels with the proper distribution injector pump it is very beneficial, if illegal.
You must accept that the authorities want pollution. The reason, to allow acceptance of swingeing stupid taxation and also control of utilization of motor vehicles.
No pollution, or reduced pollution means there is a reduced chance of acceptance of restrictions in town centers.
In the UK you can use it and arrange to pay the fuel tax.

Answer 5

Cooking oil when used in a converted Diesel engine makes about as much pollution as cooking sausages in the same oil - NONE worth noting in fact.

Answer 6

I don't know if it would be cheaper, but it would be better as it doesn't produce greenhouse gases. It's only water vapour in the exhaust emissions.

Answer 7

it does give off greenhouse gases when burnt but only as much as it has absorped when alive and growing

Answer 8

sure, it relatively is referred to as BioDeisel and it expenses approximately $4,000 to get the initiate up kit with the intention to make it. the issue with the fast nutrition supply is that it relatively is regularly alrady shriveled out!

Answer 9

yes it can make hydrolicpower
