| X4v2 Engine Independent
Certified Testing at Orbital - 31/03/2008 |
| The Directors are pleased to
announce that the X4v2 petrol engine achieved a
repeatable Brake Specific Fuel Consumption
(BSFC) figure of 212g/kW-h (38.6% engine
efficiency) with a best figure of 207g/kW-h
(39.5%) at our requested target test of 2,000rpm
with a BMEP load of 450kpa (approximately 75%
load) and an air/fuel ratio of 15.2:1 using 98
RON petrol and a 10:1 compression ratio. We also
achieved a BSFC figure under the same rev and
load conditions using an air/fuel ratio of
14.5:1 of 238g/kW-h (34.4%)...

| X4v2 Engine has been
sent to Orbital for Independent Certified
Testing - 21/02/2008 |
| The Director's are pleased
to advise that the Revetec X4 Engine has been
sent to Orbital Australia Pty Ltd at its testing
centre in Perth for independent evaluation. The
need for independently verified test data has
been requested by potential customers interested
in Revetec technology. The key objectives will
be to measure: brake power, brake torque, fuel
emissions, fuel consumption etc. The data will
then be analysed to determine: Full load power
and torque, BSCF, BSHC, BSNOx and BSCO...

First Road Test Day
for the X4v2 Report - 5/02/2008 |
| On the 25th of January 2008,
Shane and Gordon Subloo travelled to Revetec's
factory to test run the X4v2 engine in their HS4
trike for the first time. After initial
preparation, Shane drove the trike through
traffic to feel its responsiveness and
acceleration as well as drivability. We then
tested the trike at light throttle response
where we found the engine to deliver
acceleration well above a conventional engines
characteristics. As the day progressed Shane
tested the acceleration at higher throttle
openings...

| X4v2 fitted to
trike and test run in readiness for on-road fuel
testing - 18/01/2008 |
| The X4v2 engine over the
last month has been fitted into the trike for
initial on-road testing. These tests will be
performed in late January. We plan to send the
X4v2 to Orbital in early 2008 for worldwide
recognised testing, data released to car
companies and other interested parties, and
start planning the fitment of the JP8 fuel
system as per our Federal Government Grant. We
are pleased with our development progress. Our
in-house dyno fuel consumption tests (BSFC) has
shown great fuel efficiency gains...

X4v2 Development
Update - Testing Report 19/11/2007 |
| The Directors are pleased to
announce the latest test results of the X4v2
Prototype engine. We have achieved 180Nm at the
start of our dynamometer ramp test, providing
almost maximum acceleration from idle,
increasing fuel efficiencies in stop/start and
cruising situations. Enclosed in the linked
document is the latest prototype performance
data. This data includes: Power and Torque
figures, Brake Mean Effective Pressure (BMEP)
graph, 3D Fuel Injection map, Engine Benchmark
Comparisons...

X4v2 Prototype engine
is completed and fitted on the dynamometer -
24/09/2007 |
| The Directors are pleased to
announce that the X4v2 prototype engine has now
been designed, machined, assembled and running.
The engine is now fitted on the dynamometer, and
we are currently programming the engine
management system in readiness for initial
testing. Improvements made include: New higher
rigidity engine block, 4 and 8 bolt main bearing
caps, new pistons and piston assembly design,
improved bearing design, new camshaft grind,
increased valve spring rating, increased
cooling...
