Stage 1 - Develop 3 prototypes

  • Agree data capture (emissions, noise, fuel etc. ),
  • feedback and details (fitting etc. ) for initial trials
  • Understand engine characteristics for GDN activities and agree typical work cycle for base testing
  • Gather base data over a three month period of work cycles, emissions, fuel use etc.
  • Bench demonstration of prototype unit to Steering Group
  • Agree any further modifications
  • Develop and fit 3 prototype units to NGN fleet
  • Indication of future potential savings from Automatic Gearbox vehicles of CNG vehicles

Stage 2 - Initial field trials

  • Undertake three months of operation for the three prototypes
  • Gather data and feedback from trials
  • Agree any further modifications and progression to stage 3
  • Determine if any further action is required for adoption of the prototype solution across NGN (documentation, testing etc. )

The outputs for this project will be;

  • a retro-fit solution;
  •  supporting data and feedback for retro-fit solution from trials;
  • quantifiable reduced fuel use and impact on operatives and stakeholders  
Abstract Northern Gas Networks launched a call for innovation via the EIC to identify alternatives to currently used Power Take Offs (PTOs)/ On Board Power (OBP). Gardner Denver presented to NGN a number of their developed fuel saving, intelligent engine stop / start systems for large trucks for companies such as BOC, Suttons and Arla foods. The problem identified is that an OBP unit is required to run at high engine revs in order for equipment, such as electro fusion machines, to operate correctly. When an electrical appliance is required a switch is turned to engage, increasing the engine speed. This high idle uses more fuel than lower engine speed and unless the operator switches the system off at a switch the system continues at this higher speed. During the operation of PTO equipment, specifically On Board Power (OBP), the engine of vehicles used in the event of gas emergency repairs and replacement activity is left running at a high idle for long periods of time. Operators engage the system prior to leaving the cabin of the vehicle, depressing the clutch and engaging the OBP. The engine is often left engaged for the duration of work as operatives do not know when during work tasks they will need power. The high idle uses large amounts of fuel as well as creating both noise and air pollution. The solution will automatically sense the load on the electrical side of the OBP system and once the electrical load is removed will decrease the engine revs until a load is sensed again. This project will develop the currently deployed innovation into the van market and deliver a new product to work alongside current (OBP) systems. Three prototypes will be produced and field trialled to gain data. The OBP power operates in two modes and at three speeds: 1. Compressor Only Mode - in this mode the engine idles at 1200RPM and increases to 1990RPM when the operator requests compressed air. Once the operator finishes using the air, a predetermined timer allows the system to return to 1200RPM. 2. Compressor / Alternator Mode - in this mode the engine idles at 1660RPM, this is to ensure that the operator gets a continuous 50Hz from their electricity supply, the compressor also works in this state, but at 1660RPM not 1990RPM. In this mode the engine does not reduce from 1660RPM. Therefore the three speeds are: 1200 / 1660 & 1990 RPM. The compressor system utilises a pressure relief valve and pilot valve to understand whether the system is being used or not and our concept involves recreating this process within the alternator circuit of the OBP.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
