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 dynamometer 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 etc. |
