1. INTRODUCTION
The following report details the results achieved when a Toyota Landcruiser
80 vehicle was run through a single comparative test program utilising the Composite
Urban Emission Drive Cycle (CUEDC) for category NA vehicles, by Vipac Engineers
and Scientists Vehicle Emission Test facility at Altona T4009.
2. PROCEDURES
The testing was carried out in accordance with the Composite Urban Emission
Drive Cycle (CUEDC) drive cycle for NA class vehicles (vehicles with a GVM <4.5
tonnes). The CUEDC series of drive cycles were developed from data collected
during actual driving conditions around Sydney, and take the form of a single
drive-cycle (1794 seconds) broken up into four distinct phases; Congested, Residential
/ Minor, Arterial, Freeway / Highway. The two tests were driven by Mr. Bill
Sheather (Fitch Fuel Catalyst Australia Pty. Ltd.), and were run using regular
pump grade diesel fuel as agreed between Vipac Engineers and Scientists and
the customer.
Calibrated Hydrocarbon (FID), Carbon Monoxide (NDIR), Carbon Dioxide (NDIR)
and Oxides of Nitrogen (Chemuluminescence) gas analysers were used to determine
gaseous emission levels, and a NOVA 'Microtrol 4' diesel particulate measurement
unit was used to capture Particulate Matter.
A dilute gas sample was collected via a heated sample line to determine the
gaseous emission levels of Total Hydrocarbons and Oxides of Nitrogen. Dilute
samples of Carbon Monoxide and Carbon Dioxide were collected via a Constant
Volume Sampler, with ambient and sample bags being analysed to determine the
levels of pollutant. A partial dilution tunnel (the Microtrol 4) was used to
capture the emissions of Particulate Matter, the filter papers housed within
the unit being weighed prior to, and after each test to determine the mass emissions
of Particulates.
The Inertia (Road Load Setting) of the dynamometer was carried out in line
with the methods and criteria laid out within the directive UN/ECE R-83, (Uniform
Provisions Concerning The Approval Of Vehicles With Regard To The Emission Of
Pollutants According To Engine Fuel Requirements). This test is the current
certification test used in Europe and Australia for light-duty diesel engine
vehicles (equivalent to Australian Design Rule ADR 70/00), applicable to vehicles
with a GVM <4.5 tonnes and is carried out on an inertia simulation dynamometer,
replicating wind and road loads.
The first of the two tests run over the CUEDC schedule was undertaken with
the vehicle in standard showroom condition. This was followed immediately by
a second comparative test with the "Fitch Fuel Catalyst" installed
between the fuel filter and injector pump. The results of this comparative test
can be observed in tables 3.2.1 - 3.2.3 of this report.

4. CONCLUSION
From the results detailed within section 3.2 of this report, it can be
noted from tables 3.2.2. & 3.2.3, that following the installation
of the "Fitch Fuel Catalyst", there was a reduction in the Average
Tailpipe Emissions of the gasses currently legislated against within vehicle
type approval and certification tests undertaken throughout the developed
world.
The major concern with compression ignition engine vehicles at present
is finding a solution to the high levels of Oxides Of Nitrogen and Particulate
Matter emitted by such vehicles. The installation of the "Fitch Fuel
Catalyst" reduced Oxides Of Nitrogen by 13%, and Particulate Matter
by 18%. There was also a reduction in the levels of Total Hydrocarbons
(THC) 9%, Carbon Monoxide (CO) 17% and Carbon Dioxide (CO2) 11%.
Fuel efficiency was also enhanced following the installation of the "Fitch
Fuel Catalyst", primarily due to the reduction in the emitted levels
of the "Greenhouse Gas" Carbon Dioxide (CO2). An 11% decrease
in fuel consumption was achieved over the CUEDC test cycle with the "Fitch
Fuel Catalyst" installed.
