This is a nanotechnology is a South African product for diesel /petrol engines. 1. Engines last longer, runs cheaper, cooler, smoother and substantially reduced soot and odour. 2. Cost savings 10 to15% ( transport )and up to 28% on generators. 3. Use 3ml naftech to 1L fuel (300ml to 100L diesel ) 4. Less GHG ( green house gas ) emissions. 5. Tested by CSIR and SABS approved (SANS 324 for diesel and SANS 1598 for petrol) Naftech serves on the board of ASTM ( American Society for Testing Materials ) witch sets the international petroleum standards in 53 countries world wide. Mechanical engineers are in the team for technical assistance.

Report of findings on testing NAF-TECH fuel additive –
26 & 27th
August 2009
Testing of the fuel additive was conducted at the Diesel Electric Services factory in Ophirton,
Johannesburg which is 1750 Metres above sea level at an ambient temperature of +/- 18
0
C.
A diesel driven generator was used for the testing and the loading of the engine was achieved
by connecting resistive dummy loads to the alternator output terminals, the machine used was
an SDMO J110 unit consisting of a John Deere 4045HF120 engine coupled to a Leroy Somer
44.2V545J/4 alternator rated at 110kVA at 400v @ 0.8 Power factor.
This engine is a “standard” 4 cylinder diesel engine fitted with a Rotary Injector pump and an
Electric Speed Governor and is a Turbo-charged engine.
The testing was planned to be done across the load range at these levels; 25%, 50%, 60%,
70% and 100% with a procedure in place and recordings taken at 15 minute intervals for 1
hour. The engine water temperature & oil pressure were recorded along with the output voltage,
frequency and amperage on the alternator.
In order to have an accurate account of the fuel level a small 50 litre tank was used as a fuel
tank connected to the engine supply and return lines using flexible hoses, the tank had a drain
cock at the bottom and a calibrated measuring jug was used to fill and empty the fuel tank.
The procedure was to put 30 measured litres into the tank; run the machine for 1 hour then stop
the engine and drain the tank using the measuring jug to see the quantity of remaining fuel left
in the tank. The tank was then re-filled to 30 litres for the next test and so on each time
recording the ‘Start’ fuel level and the ‘Finish’ amount of fuel thus the difference is the
consumed fuel.
Firstly the engine was run at all the load levels on “standard” diesel fuel, followed the next day
by being run at all the load levels on the same diesel with NAF-TECH added at a rate of 2ml per
litre of diesel.
The kW load was calculated and converted into amperes for ease of measuring as a current
tong tester was used to measure the load during all the tests, the following rules apply:
110kVA @ 0.8 Pf = 88kW is the rated output of the generator at 400v / 50Hz.

Amps = kW x 1000 ÷ 1.732 x Voltage (400) x Pf (1), therefore the testing range was as follows:
25% = 22kW / 31.75Amps
50% = 44kW / 63.5Amps
60% = 52.8kW / 76.2Amps
70% = 61.6kW / 88.9Amps
100% = 88kW / 127Amps
Our resistive dummy load is at a Power factor of 1 or unity as it is purely a resistive load, also
the smallest steps are steps of 9kW so the load applied was not as precise as the above figures
but as the exact identical load was applied in both tests there were no differences.
The test results are as follows:

As well as this recorded data there were some other noticeable changes when running the
engine with NAF-TECH diesel; the exhaust gases did not smell of diesel as when on diesel only
and the exhaust gas was not as hot as when on diesel only emission levels will be confirmed at
a later date following tests conducted with CSIR. We did take some temperature readings but
the correct instrument was not available and a Laser gun device was used which is not 100%
accurate, the exhaust was at 427
o
C on 100% load with NAF-TECH whereas the engine
manufacturer specifies 545
o
C at full load.
The start-up black smoke was seen to be less which has been recorded on video as well as
some of the testing itself.
