Meeting environmental directives for emission
control is becoming an increasingly wide spread
requirement and being able to record and report
statistics for fuel efficiency is one method towards
helping to achieve this.
The DSE8610MKII synchronising and load
sharing genset control module is the latest
product from DSE containing the most
sophisticated features including Fuel Efficiency.
By measuring kW and fuel usage over a time
period, the control module can calculate the kW
hour per litre achieved by the generator. The
information is collected by the control module
from different sources depending on the engine
type, and results are displayed and can be stored
within Data Logging to provide useful trending
graphs.
TRADITIONAL OR MECHANICAL ENGINES
Using information from a fuel level sensor within
the fuel tank and engine run times, together
with the manufacturers’ fuel consumption data
(fuel map), and provides average efficiency
measurements.
ECU AND TIER 4 ENGINES
By collecting kW, fuel usage and engine run time
information from the ECU, the control module, in
addition to providing an average measurement,
can also provide instantaneous information for
measurements occurring at that moment.
By extracting this information from the
DSE8610MKII control module and using
the manufacturers’ published performance
specifications, the user can then calculate
the emission output. This works on the
assumption that the engine is running at its
optimum performance and the data can be
used to compare the planned efficiency with
the actual achieved. This is extremely useful
as the application may be influenced over time
by external conditions reducing the engines
efficiency; such as poor maintenance
leading the engine to not ‘run clean’
and therefore increasing emissions.
The function allows the user to investigate
variations beyond the acceptable tolerances and
use our advanced PLC programming inside the
module to set alarms.
Using the manufacturers guidelines for fuel usage,
this feature can also be used as an indicator of
engine condition e.g. if more fuel is being used
it could indicate a worn engine, so preventative
maintenance can be carried out.
At present the fuel efficiency feature is available in
the DSE86XXMKII modules. It will soon be made
available within the DSE73XXMKII modules.
