Article is devoted to production of a biodiesel engine from various vegetable oils. In it it is said that in our country already there are the enterprises which are letting out the equipment for production of a biodiesel engine in the conditions of a small farm. The firm "Biodiesel Dnepr" lets out small installations for production of a biodiesel engine that is called in house conditions.
Article is intended for agricultural enterprises, farms and is of interest for laymen.

In the first half of the year 2006 in Kiev two exhibitions on which production of the Ukrainian producers of a biodiesel engine was presented took place.
For the world countries today it already reality: diesel fuel replace with cheaper and non-polluting fuel – methyl air of oil acids or a biodiesel engine.
In Ukraine plants on biodiesel engine release only start to be under construction. We with it considerably are late. The West and successfully puts long ago a biodiesel engine into practice.
At the beginning of research of new biological fuel by a biodiesel engine called a mix of mineral diesel fuel with rape oil (and only with rape). Such mixes prepared in the ratio 5-30 % of rape oil and 95-70 % of mineral diesel fuel. Quality of a mix was not so high therefore operation of the engine became unstable therefore the biodiesel engine can’t be been used in pure form but only as the additive in mineral diesel fuel. Quality of the most vegetable oil too isn’t indifferent for equipment.
Today the biodiesel engine already is developed from any vegetable oil which can be bought or received from seeds. Quality of a biodiesel engine depends, first of all, on extent of preparation of vegetable oil to biodiesel engine manufacturing. Oil shouldn’t contain some mechanical impurity, that is it is necessary for filtering. For receiving the biodiesel engine which is meeting the requirements of the European standards, vegetable oil is necessary for clearing even more carefully, and a biodiesel engine – to wash out.
Why biodiesel engine?
The biodiesel engine or biodiesel fuel is the non-polluting type of fuel alternative in relation to mineral types, received of vegetable oils and used for replacement (economy) of usual diesel fuel. Various vegetable oils can be raw materials for production of a biodiesel engine: rape, soya, peanut, palm, the fulfilled sunflower and olive oils (used, for example, when cooking), and also animal fats.
From the chemical point of view the biodiesel engine represents methyl air. The biodiesel engine can be used in usual internal combustion engines as is independent, and in a mix with usual diesel fuel without modification of an engine design.
Possessing approximately an energy potential identical with mineral diesel fuel, the biodiesel engine has a number of essential advantages it:
– it is not toxic, practically doesn’t contain some sulfur and cancerogenic benzene;
– decays under natural conditions (approximately also as sugar);
– provides considerable decrease in harmful emissions in the atmosphere when burning both in internal combustion engines, and in technological units;
– increases tsetanovy number of fuel and its greasing ability that essentially increases an engine resource;
– has high temperature of ignition (more 1000S) that does its use rather safe;
– its source are renewable resources.
Production of a biodiesel engine is easy for organizing, including in the conditions of a small farm, the inexpensive equipment is thus used. In our country already there are the enterprises letting out and establishing the equipment for production of a biodiesel engine in the conditions of a small farm.
Biodiesel engine cost doesn’t exceed now cost of "oil" diesel fuel and tends to decrease. Experts in motor equipment consider a biodiesel engine as the best fuel for motors with spontaneous ignition, and the most perspective for Ukraine raw materials for production of a biodiesel engine, in their opinion, the rape is.
For example, the firm "Biodiesel Dnepr" who is letting out small installations for production of a biodiesel engine that is called in house conditions, uses German technologies. These technologies demand application of only rape oil and only the refined. However when manufacturing biodiesel engine producers tried to find certain "golden mean" when it is possible to allow some deviation from quality indicators and to reduce costs of purification of oil. Any vegetable oil is thus used. Practice shows that it is possible to use oil without preliminary cleaning, having pressed through it via the filter wood and made of cloth (the elementary refinement). Phosphorus, mechanical impurity and water thus are removed. Without cleaning, after a sediment mustard oil of own production is used even. According to producers, their biodiesel engine was investigated by many consumers and complaints weren’t.
But, without watching even at the simplest way of production of a biodiesel engine, it is necessary to consider its technical and chemical indicators and to observe the production technology.
