Ibiza oil seeds ( pdf biodiesel )

TDI ENGINE OIL SEED, AND COMMONRAIL

About five ago I bought a SAeT ibiza 1.9TDI 90cv, pretty much just went out to take the TG2 servizzzi some people uavano rapeseed oil instead of diesel curiosity I also tried the lot trying, with the first few liters to go up with time% , until about a year ago when I stopped using diesel.
Obviously, I been reading up on the internet, where I found everything I needed to do things conscientiously.
To date, there were no incidents after traveling all around 65.000km with alternative fuels in various%, in fact if I initially used it anhée rapeseed oil, they soon switched to oils of all kinds, and especially to used oil recovered in restaurants. When I have time I self-produced biodiesel (a total of about 300 liters or slightly more)

Here I summarize the knowledge acquired in these five years:

A diesel cycle engine can burn (theoretically) everything is flammable.
In reality for them as we have developed now need liquid fuels, not too sticky and good lubricating capacity.
So theoretically all engines can burn pure vegetable oil, which leads to the following benefits.
Not emit more unburned hydrocarbons
The CO2 produced is less than that absorbed by the plant in his life
The particulate products are smaller, larger and less carcinogenic.
The main disadvantages however are:
Slight increase in the production of nitrogen oxides (eliminated by updating the control characteristics of the new fuel)
Excessive oil viscosity.
To avoid the problem of viscosity, or even the risk of freezing of 'oil inside the piping is preferred stretch with at least a 10/15% of heating oil in winter, but in doing so not all machines can use it.
The older machines (indirect injection) are the most suitable
The recent machines (common rail) may instead cause problems.
In both cases, the delicate part is the fuel pump, which spray the oil too viscous fails, then you prefer to heat the oil to burn in order to make it more fluid and avoid any problem.
In the old car engine is cold a few electric heaters heat the oil to about 90 degrees before it enters the injection pump.
Once entered into the engine oil temperature is heated by the cooling circuit. (My car is new in design but use this system because it is easier to use)
In new cars you prefer to start the diesel engine and once it reaches a certain temperature switch to oil, as is already done in the car to LPG or CNG.
In some cases it may be that the oil pump is not disturbed, but in reality, 'even though the pump is not damaged but the oil is sprayed bad finishing the walls of the cylinder without burning completely, will end' engine oil, diluted and change its characteristics with dire consequences for the entire engine!
A simple way to verify that this does not happen is to periodically check the level dell'lubrificante, if the level increases with time to replace it immediately and seek a better heater or decrease the percentage of oil.
Finally there is still a good series on oil using engines equipped with particulate filter, which could be damaged, but certainly no longer serve.

Not to change the engine in any way you can use biodiesel, but that 'it is less eco-friendly.
In fact it is used to create energy, alcohol and caustic soda which worsen the overall budget.
As a byproduct of this reaction has glycerin, which is useful in many areas (cosmetics, agriculture, military), I use it to fertilize the garden.
Biodiesel is different from the oil obtained by being much more fluid and not have to be preheated.
It can go on any engine without special precautions, although some cars may be advisable to replace the fuel lines because the biod is a little more acid.
I produce (from oils) to give it to my friends who do not want to change the car, there are also machines that produce it automatically guarantee quality.
My car goes instead to simply filtered waste oil with an old shirt, I occasionally clogs the fuel filter but I never had any other problems.
To go to 100% of oil in the winter, I recently installed a heater on a budget less than $ 100.
Even with biodiesel there is a sufficient case studies on its use on machines equipped with particulate filter, which applies the same considerations made for the pure oil.
Obviously if you plan to replace oil with vegetable oils we immediately realize that the earth is not big enough to grow enough oilseed crops, we should abolish any other type of crop.
Instead much sense to use that land unprofitable, but suitable for pioneer plants (such as rape in the cold Nordic countries) to integrate energy demand.
Even better recycle fried oils, which become costly waste into useful fuels.
Finally it seems very likely to use algae to produce oil which passes 100tonnellate yield per hectare against the 5 / 7 terrestrial cultures, has more than purify water from nitrites present and not to be seasonal, so a higher yield, more 'stable, comfortable and purifying water (do research on American and lakes polluted Adriatic Sea, both studies are going very well and the waters are clearing).
With the use of micro-algae could possibly replace fossil fuels entirely.
About as in parts of 'America converts to target food crops with low yield oil crops (sunflower), with hyper-polluting farming methods (so nobody eats them), maybe he does only for a friendly facade, actually' often the overall budget is worse than diesel!

Here I have summarized very briefly the use of vegetable oils and their derivatives (esters), similar considerations can be made on other alternatives to diesel fuel (FT-diesel Gecam ... ..), or alternatives to gasoline (alcohol, etc. ..), and the installation of regasification plants (really not very useful).

Also, for those who wish to have a smattering general about what they are and what are renewable energy, can read the documents that describe the underlying convengno in Santa Maria a Monte, where they are well-described advantages and disadvantages of the most common renewable energy sources: biofuels, PV, geothermal and wind
