Introduction by Tony Hockings CChem MRSC, MNZIC
We have prepared this presentation in order to provide you with an insight into the technology Enviro-Tab have developed to enhance combustion efficiency, minimise pollution and maximise the fuel efficiency of New Zealand vehicles.
I am a professional analytical chemist who has worked in the Petroleum Industry in Europe and NZ for the past 24 years.
I have worked for Oil Companies and Refineries in R & D and QC, I am a ‘Member of the Royal Institute of Chemistry’ and the New Zealand Institute.
Over the past year I have been consulting with Enviro-Tab establishing vehicle emission trial protocols for a controlled trial of their innovative fuel conditioner, the Enviro-Tab.
We have completed the initial phase of this trial and I am going to present the data we have gathered to date then draw some conclusions.
Vehicle Trial Protocols
The vehicle testing programme was designed to monitor the effect of Enviro-Tab gasoline and diesel fuel conditioner on vehicle emissions and combustion efficiency in ‘real life’ New Zealand driving conditions.
Anecdotal data, though compelling, has little scientific value and in order to validate the emission trial data we have gathered over recent months we have applied a rigorous set of testing protocols to our vehicle tests.
Used Petrol and Diesel vehicles were selected at random and tested as received with no unscheduled servicing or tuning.
All vehicle emission tests were completed by Zero Emissions Ltd, Browns Bay, Auckland.
Zero Emissions testing equipment has been calibrated to traceable European Standards.
The following trial protocols were developed and applied to the testing.
1.The test vehicle (with a less than 25% full fuel tank) was tested by Zero Emissions to the protocols detailed below:
Gasoline Vehicle :
CO (Carbon Monoxide) – Idle and High Idle
HC (Hydrocarbons) – Idle and High Idle
CO2 (Carbon Dioxide) – Idle and High Idle
O2 (Oxygen) – Idle and High Idle
Lambda – Idle and High Idle
Diesel Vehicle :
Diesel Opacity Test – Average K value of 3 readings
2.The fuel conditioner was added to the vehicle and the bonnet sealed with a numbered sticker. Photos were taken of the sticker and vehicle registration.
(These photos may be used to validate the test date.)
3.The vehicle was filled with fuel from a major supplier (e.g. regular 91 octane from Shell) and a record kept of the type and volume of fuel and date purchased (invoices required).
4.The vehicle was driven the initial test mileage (to date tests have been completed between 19km – 2,127km) with fuel conditioner being added at each refueling.
5.The vehicle emissions were retested by Zero Emissions who confirmed that the bonnet sticker was intact and the bonnet had not been opened by initialing the certificate of compliance result sheet.
6.If extended testing was completed the bonnet was resealed, further mileage driven then the vehicle emissions were retested by Zero Emissions who reconfirmed that the bonnet sticker was intact.
