Enerpulse Performance Evaluation Procedure (E-PEP) |
|
|
|
The Enerpulse Performance Evaluation Procedure (E-PEP) is a test
method for comparing the performance of pulse plugs against that
of spark plugs and documenting the comparison in four
performance categories: fuel economy, acceleration, horsepower,
and torque. Subject vehicles have worn out spark plugs replaced
with factory recommended new spark plugs, spark gap settings,
tire pressures and fuel. Fuel flow meters are installed into the
vehicle’s fuel lines (incoming and return) and linked to a
computer to register real-time fuel flow throughout the test to
an accuracy of 1/42,000th of a gallon. The vehicle is then setup
up on the Enerpulse Mustang chassis dynamometer. |
 |
 |
 |
|
Once prepared, the vehicle is put through a series of tests on
the chassis dynamometer. The first of this series of tests is
designed to measure horsepower and torque. Typically 3 pulls
from low RPM to redline are made on the dyno to measure the
output of the engine with factory plugs. If the car is
consistent on the dyno, then this data is used for baseline
horsepower and torque readings. In many cases it takes several
runs for the stock ECU to get accustomed to running on the
chassis dynamometer. In this case, more runs are made until
consistent results can be achieved. |
|
|
|
The last category of the test focuses on fuel economy. The car
is driven on the dyno following the Environmental Protection
Agency's (EPA) US06 driving trace. This test is one part of the
US EPA’s fuel economy testing and represents a real world mixed
highway driving condition with many passing acceleration ramps
and high speeds reaching over 80mph. The flow meters are
monitored during this test and the results in cubic centimeters
of fuel are recorded in the Mustang chassis dynamometer file. |
|
|
When E-PEP is completed for the stock factory spark plug,
Pulstar™ pulse plugs are installed. The E-PEP is then run again
with pulse plugs. The results are then compared between the
factory plugs and the appropriate Pulstar pulse plug. The graph
outputs are scanned from the dyno onto the E-PEP server and a
master database file of the results is updated. |
 |
|
|
|
The performance of your vehicle may vary with the age and
condition of your car, weather, and your driving habits.
Remember that pulse plugs are an investment. |
