Background of Invention Petroleum is a conventional natural fuel resource that its stock has be reduced in the earth. This fuel resource is unsustainable resourc Therefore, finding a new fuel resource is very important in present and futu Additionally, finding sustainable fuel resources need to be considered.

Plants or vegetables are a sustainable resource for oil. The pla or vegetables can be regeneration by cultivation in field area. By maintaining the regeneration, oil can be resulted continuously.

The oil resulted from plants or vegetables are generally friendly environment. It means that the oil does not create environment degradation is showed by number of using the vegetable oil for daily food cooking. The oil resulted from plants or vegetables cannot be consumed as oil fuel by diesel machine, it needs certain further chemical process. T chemical process that used to convert vegetable oil is transesterification. In t process, triglyceride contained the vegetable oil is reacted by methanol a hydroxide catalyst to produce methyl ester. Produced methyl ester is ready use by diesei machine.

The usage of vegetable oil as a fuel by chemical processi mentioned above generally known as bio-diesel. Bio-diesel fuel has been used many countries. For Indonesia, The Agency for Applying and Assessment Technology (BPPT) has proposed the bio-diesel fuel as diesel fuel replacemen

Chemical process described above makes usage of vegetab ineffective. Basically, vegetable oil cannot be used directly as fuel so specific chemical process. Therefore, this invention provides the how to use vegetable oil as a fuel for diesel machine directly

5 separated chemical process.

Detail Description of Invention

A diesel machine is characterized by high compression system, it makes burning system works without sparkplug. By changing pressure and temperature in the burn chamber, the fuel will be burnt and then reaches ignition point, thus will produce the power. Properties of suitable fuel for diesel machine are listed in Table 1.

However, as the extinction of natural fuel resources and the increasing of fuel price,- we need to find other alternatives of natural fuel resources that become a sustainable fuel. The vegetable oil, which is friendly with environment, gradually increases with lower prices, it can be develop as alternative fuel resources.

Table 1

Bio Oil or vegetable oil is classified as oil that comes from chemical or mechanical extraction from a portion or all of part of plants. An example is Jatropa Cucas Sp. Jatropa Cucas Sp oil made from mechanical oil compression which rough jatropa oil must be filtered, dried, stabilized, and treated de-gumming process. Preparation or processing of this oil process will not be discussed here in detail. Bio Oil or vegetable oil in this invention refers to oil from vegetable extraction through purification process as mentioned above. Vegetable oil has basic features as shown in Table 2. Based on the Table 2, showed that spark point and high viscosities will reduce heating process of fuel in diesel machine. Table 2

This invention provides an apparatus to convert vegetable oil that physically characteristics have been changed so that it suitable to use in diesel machine. Further, the particularly of this invention will be described based on the included drawings. . Now, with reference to Figure 1 that describes how Bio Oil is treated. It is put in to first heating chamber ( 1 1 ) , which has the heat from radiator hot water. Controlling temperature of heater chamber, a solenoid valve (14) is attached to radiator water inlet that utilized a controller or mechanic thermostat. Within heater chamber, bio oil will be thinned. Thinning process will reduce viscosity of the fuel. Through this process, bio diesel will be well sprayed by nozzle.

If it is needed, the heater component can be added as a heater filament ( 1 7 ) . The heater filament (17) operated by electrical power from battery or storage battery car. The used heater filament (17) controlled from 100 watt up to 500 watt. Heater filament will be operated while machine temperature is less than sufficient condition due to radiator water unable to give suitable heat. Bio Oil temperature that followed this heating process can be adjusted between 50° - 115°C depends on specific property of the used Bio Oil. Oil with high viscosities needs higher heat.

Heating chamber ( 1 5 , 16) of vegetable oil converting apparatus in this invention is like spiral or thread shape, it results uniform heat to overall vegetable oil. Except heating source from heating chamber, the heat can be taken from exhaust port (muffler) of diesel machine.

Now referring to Figure 2 as another alternative of heating of Bio Oil, it can take the heat from Hollow Foil or metal pipe attached to exhaust port of diesel machine, so it will increase Bio Oil temperature fast. Figure 2 illustrates conversion of vegetable oil by heat source from exhaust port.

What should be considered of these two ways conversion is that the temperature should not be too extreme so the ignition point will not be reached at the output of this apparatus. For Jatropha Sp oil, the temperature setting is

between 60 ⁰ C -75°C, Ricinυs Sp oil is between 80 ⁰ C - 90 ⁰ C. Other oils can be determined directly by try and error, therefore this apparatus will supported in the various temperature.

The detail embodiment of this invention is shown at Figure 3. The starting heat system can be deployed within fuel system configuration as seen at Figure 3. In Figure 3, there is diesel fuel tank that contains diesel fuel (31) and the tank that contain Bio Oil (32).

Driver or operator of the diesel machine can choose machine procedure manually between 2 tanks or automatically gives the operation to program controller ( 3 3 ) . In automatic mode, as machine starts, the fuel pump (34) will connect to fuel tank by T-Switch ( 35 ) or channel determining solenoid. Machine can normally work with diesel fuel. If hot radiator water start heating Bio Oil and temperature sensor ( 3 6 ) as thermocouple or bimetal detects Bio Oil temperature in heating chamber ( 37 ) is achieved certain temperature (sufficient hot), thus the programmable control {33 ) can react to activate T-Switch (35) so channel to the fuel pump will be connected to outlet of vegetable oil (Bio Oil).

Whether needed, heater filament (38) can automatically work to stabilize temperature, or co-work with water radiator to reach the specified temperature. This filament is used whether the specified heat is insufficient. Commonly occurs on the beginning of operating machine.

If operator stops machine in automatic system mode, so program controller (3 3 ) will order T-switch (35) to move fuel channel to fuel tank (31 ) and then stop terminate electric current to heating component (38) and radiator water heating channel ( 39 ) then machine can operate for 1 - 5 minutes before program controller stops fuel pump ( 3 4 ) . It occurs due to this converting apparatus equipped by a manual terminating vegetable oil flow (40) that operated before turning off the machine. Therefore, flushing automatically operates. This process

will guarantee that the residual of Bio Oil will be cleaned from fuel pump. Filter (4 1 ) will help to filter Bio Oil if there is still much dirt in tire tank.

This apparatus can make vegetable oil (Bio Oil) able to power diesel machine as replacement of diesel fuel. This apparatus used directly without chemical process of vegetable oil.
