“…There are several studies ( [52], [53], [66], [77], [84], [87], [88]) in which the fuel heating is investigated. It has been proved that preheating the vegetable oil assure a viscosity 80% lower than unheated oil, and similar to diesel fuel.…”

“…If the fuel is too thick it will not atomise properly when the fuel injectors spray it into the combustion chamber and it will not combust properly. Furthermore the injectors get coked up, leading to poor performance, higher exhaust emissions and reduced engine life( [59], [80], [83], [88], [89]). …”

“…A poor seed quality, processing and pressing can led to engine damage and bad performance. The lack of quality standard requirements or worldwide regulation for seed oils is still an issue that has to be solved ( [59], [88], [96][97][98]) In Europe, only Germany set out a Quality Standard DIN 51605 for rapeseed oil (RKQualitätsstandard) [59].…”

The pollution caused by fuel combustion either for mechanical or electrical energy generation purposes is nowadays one of the most important environmental issues. It has been proven that combustion emissions, particularly those from cars and trucks, are linked with severe damages to the environment and human health. Along with the environmental problems, is necessary to consider that fossil resources are declining and their exploitation is getting more and more expensive. Bioenergy represent a sustainable solution for energy generation. Bioenergy is renewable energy made from plant-derived organic matter, collectively termed "biomass". Biomass-based energy sources are potentially carbon dioxide neutral and recycle the same carbon atoms. Life cycle assessments are reported to evaluate the net environmental impacts of biofuels. The term biofuel refers to liquid or gaseous fuels for the internal combustion engines that are predominantly produced from biomass. Biofuel policy might capitalize on the production of biofuels supporting rural economic development and sustainable agriculture. Amongst biofuels pure plant oil (PPO) has been investigated. This paper sets out to review the state of the art for PPO use as fuel in diesel engines, based on a wide literature review.

“…This model is based on first converting to oil a portion of harvested rapeseed, which is then consumed as biofuel. The introduction of rapeseed to the crop rotation system in a Spanish Mediterranean zone to produce straight vegetable oil (SVO) for fuel on the same farm is shown in Grau et al [16]. SVO is a biofuel obtained by pressing, filtering and degumming rapeseed without any chemical process.…”

The use of straight vegetable oil (SVO) as biofuel has been recognized as a valid substitute of diesel fuel in the agricultural sector under specific circumstances. Its direct use reduces most of the chemical processes involved when converting it into biodiesel, thus lowering harmful emissions. This study presents the economic analysis of a selfsupply farming model that uses rapeseed as its fuel base. This model addresses agricultural environmental concerns and can even minimize dependence on the fluctuating costs of diesel fuel. The use of SVO in agriculture can help reduce farmers' vulnerability to fossil fuel prices. The economic evaluation of the model proposed in this study shows clear economic benefits of introducing rapeseed to the traditional crop rotation of wheat and barley. The key factors analyzed in this model are diesel fuel price, diesel fuel grants and crop aids. The current situation in Spain favors the use of diesel fuel in agriculture rather than rapeseed SVO due to an 8% profit difference. However, results show that changes in key factors slightly affect the profit margin, calculating a difference of only 3.7% for particular factor combinations. Combined environmentalfriendly agriculture supporting policies are necessary to cover this slight profit difference to promote this biofuel.

“…As regards life-cycle energy and greenhouse gas emission analyses, these reveal considerable advantages of raw plant oils over fossil diesel and biodiesel. It is pointed out (Grau et al, 2010) that straight vegetable oil can be used directly in diesel engines with minor modifications. It is proposed a small-scale production system for selfsupply in agricultural machinery.…”
