Performance
All performance figures given are for informational purposes
only and are suject to change until development testing is
complete.
Test Program Elements:
| Element |
Description |
| Power |
This element is fairly self explanatory. Power
from the test engine is measured and charted and compared to our goals.
Changes are made in the test engine until power output meets or exceeds
all our design criteria. |
| Fuel Consumption |
Again fairly self explanatory. Fuel consumption
numbers are gathered over the entire operational range of the engine and
compared to the power output. Changes are then made to optimize fuel consumption.
For example, if engine power exceeds requirements at any particular point
in the engines operating range it can be adjusted to enhance fuel economy.
|
| Operational |
This element entails numerous tests of all the
factors that go into the regular use of an engine. Some of the areas
evaluated are: starting, including cold starting; stopping; throttle response,
including throttle response under various load conditions; sudden stoppage;
and various off design conditions, including but not limited to, over speed,
over power, vibration, operability under damage conditions such as various
cylinders not firing or no coolant or no oil or a combination of these
factors. Practically anything bad that you can think of that can
happen to an engine is included in these tests.
|
| Endurance |
Engines are run under various load conditions
for extended periods of time. Test engines are periodically disassembled
and checked for wear.
It is noteworthy that all of our engine designs, be they marine,
stationery or aircraft, are required to meet the conditions of the Federal
Aviation Administration's Part 33.49 Endurance Test. |
The above listed Test Program Elements are the four that
we think that the public would be most interested in.

The numbers on the right indicate where in the testing
program we are. A ten would indicate an area of development that was
full production ready. Since each Test Element is comprised of literally
dozens of individual tests, the scores shown in Status->Progress are
in fact averages and do not indicate the status of any particular individual
test.
Discussion:
| Power |
Overall, the power production element is proceeding
most satisfactorily. All of the engines in this family have met
or exceeded all target projections for power output. Marine and stationery
engine power curves are for all practical purposes finalized. Some
adjustment is still ongoing on the aircraft engine power curve.
|
| Fuel Consumption |
Early in the testing program fuel consumption
numbers were found be slightly better than projected. Because of this,
fuel consumption optimization has been moved a little further down the
list of things to do. We do not anticipate any difficulty in achieving
our target BSFC. Since there is no such thing as having your fuel economy
be too good, we will continue working in this area.
|
| Operational |
Operational testing is proceeding according to
plan. All of the tests that have been run have been satisfactorily completed.
As the chart above indicates we are approximately halfway through this
test element.
|
| Endurance |
Endurance testing per se, is just beginning. Of
course all of the hours accumulated in dynamometer testing go towards
evaluating endurance. By its very nature this program element takes a
considerable period of time to complete.
|
Please understand that there is a great deal of overlap
in these test elements and that the testing schedule is
constantly being evaluated and rearranged. Areas that need
more work are moved higher in the priority list and consequently others
are moved down. The above given information is a generalization designed
solely to give an overview of where we are at any given time.

Dimensions
At the present time Nivek R&D is preparing charts
and graphs of some of the more relevant engine operating parameters
such as HP vs RPM, Torque vs RPM, and BSFC. When complete, they will
be added to this page.
