The use of vegetable oils in diesel engines different. Biodiesel, Veggie / Kero Mix, Straight Vegetable Oil.

The history of diesel engines and diesel fuel.
Dr. Rudolf Diesel (.Rudolf Diesel.) Is a German who invented the diesel engine has completed in the year 2425, which at that time, he used peanut oil as fuel in the experiment. Airplane, he finally succeeded. And a prototype of the diesel engine to date.

Diesel engine. Works by compressing air to high heat. When injected into fuel, it will burn up. The hot gas is expanded. Push the piston to move to send power out.
Diesel fuel. From the discovery of oil which is hidden under the ground. And be refined as a product. The main one is oil, which has been used extensively in diesel engines. Estimates are that crude oil will begin to expire in the next 50 years.
Therefore, countries around the world have worked to find ways to meet the educational crisis that will occur in the near future, and Thailand is one of the countries studied to find ways to accommodate these problems.

Application of vegetable oil used in diesel engines, including a 3 approach.1. Biodiesel (Biodiesel).
2. Kerosene Mix Vegetable Oil (Veggie / Kero Mix).
3. Use cooking oil directly (Straight Vegetable Oil).
Details are as follows.

1. Biodiesel (Biodiesel). Is a method widely used. By adding vegetable oil to react with Alcohol and alkali Is biodiesel. Which is in the form of A methyl ester and glycerine. Biodiesel can be a feature very similar to diesel fuel. Can be added to all types of diesel engines and added directly into the fuel mix of 20% the current price of diesel fuel has more than 1-2 times.
2. Kerosene Mix Vegetable Oil (Veggie / Kero Mix). How to kill with kerosene oil. Oil obtained from these methods. Suitable for use if needed. Oil urgently. And used on heavy-duty engines. And use in tropical climates, the blend of kerosene and vegetable oil, depending on the temperature of the active area ratio from 10% Kerosene + 90% oil to 40% Kerosene + 60% vegetable oil, mixing the appropriate address. 20% Kerosene + 80% oil, however, to add Efficiency in the use of vegetable oil mixed with kerosene. To install tanks or diesel fuel in order to start the engine and disable the engine at first. This method is currently being delivered to the user. But because the price of kerosene to the high volume of diesel fuel is too small to be mixed when used, so the impact of engine problems. Incomplete combustion of the fuel mixture.
3. Direct use of vegetable oil (Straight Vegetable Oil). Is how the pure vegetable oil or vegetable oil use, the reactors that require diesel vehicles tank. Diesel or biodiesel in order to start the engine and before Stop the engine. Highlights of the direct use of vegetable oil is heated to a point where all the oil in the fuel tank through a pipeline corridor, including oil. Oil filter kit. The temperature of the hot oil, at least 70 oC.

Ways to bring oil directly to the way that oil prices are by Particular. Bring vegetable oil refining process, which is not used. But to use them properly requires heat to melt strength and reduce fever viscosity of the oil.
