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.
