2. Turning Diesel into “Greener Fuel”
Complete Fuel Combustion:
2 C16H34(Fuel) + 49 O2 → 32 CO2 + 34 H2O + Heat
• Most Efficient
• Ideal, but unrealistic
Incomplete Fuel Combustion:
2 C16H34(Fuel) + Air (20.8% O2) → C + CO + CO2 + H2O + Heat
• Waste of Fuel
• Reality
Engine’ incomplete combustion leads some major pollutants:
• Carbon particulate
• CO
• NOx (Mainly NO and NO2)
• Smog (VOCs + CO + NOx + Sunlight)

3. • Add O2 content into the fuel
• Add Lubricant(s) into the fuel
• Take away H2O content in the fuel

• Reduce Particulate Matter
• Reduce NOx Emission
• Reduce CO Emission
• Reduce Exhaust Emission

9. “How It Works”
Micro-Explosions Occur Inside the Atomized Diesel Droplet
• Forms " Nano-Grade" particle (10-100nm) in the diesel fuel
• Above 250oC, superheating causes Micro-Explosion (Secondary Atomization)
• Further fragmentation into finer fragments
• Diesel is, then, burned more effectively.
Benefits:
• Ensure Complete Combustion inside the Combustion Chamber
• Lowering Combustion Chamber Temperature, reducing NOx

11. Case Sharing

One of the sub-contractors (at H.I.T.) participated in our Diesel Additive Program, 7 trucks were
deployed to monitor their CO emission. Of which, one vehicle (#86) used 油霸TM Masterbatch
brand and another (#38) used a different brand, the other 5 vehicles did not use any additive, as
control references.

Remark:
1. The value of “ ? ” indicates the relative diesel consumption rate. Lesser the figure means better fuel
efficiency.
2. Determination of CO, using Summit-708 Flue Gas Analyzer, was reference to ASTM D6522 (Standard Test
Method for Determination of Nitrogen Oxides, Carbon Monoxide, & Oxygen Concentrations in Emissions
from Natural Gas-Fired Reciprocating Engines, Combustion Turbines, Boilers, & Process Heaters Using
Portable Analyzers).

Hong Kong
A Hong Kong based Construction Firm participated in our Diesel Additive Program. A diesel Gen. Set was used to
assess the 2 correlation tests, i.e. (1). with “diesel fuel” as control; (2). test was conducted similar to (1), but with
added “Diesel Additive” in diesel with ratio of 1:1000. Resultant data were as below:

In Southern China region, the recorded diesel efficiency were
measured at between 14 – 18%
Coach currently using our
“Diesel Additive”
Company’s Registration Plate Driver’s ID
Coaches’ diesel consumptions were usually measured at
between 220 to 223 liters per trip.
For coaches, which using Diesel Additive,
their diesel consumption were found to be
in the range of 180 to 188 liters per trip.

14. Ad-Hoc Issues
The HKSAR’s Chief Executive, Mr. C.Y. Leung stated his 2015 Policy Address on
“Air Quality”:
• Ocean-going vessels at berth in HK to switch to low-sulphur diesel
• Set up low emission zones in Causeway Bay, Central & Mong Kok at the end
of 2015
• Franchised bus companies can only deploy low-emission buses
• Working with Guangdong authorities, requiring ocean-going vessels in
Pearl River Delta to switch to cleaner fuel
• Non-road Mobile Machinery, i.e. generators & excavators to comply with
statutory emission standards (EU Stage IIIA), tentative effective date would
be, 1 April 2015
