1. The document describes a new common rail system called the Ganser CRS that is suited for retrofitting and new off-road engines. 2. The Ganser CRS uses a wave dynamics and dampening system that allows for individual injector accumulators without the need for rails, providing higher injection pressures and fuel efficiency. 3. Testing showed the Ganser CRS provided up to 20% higher injection pressure at the nozzle and up to 15% lower fuel consumption compared to conventional common rail systems.

11. Advantages of the WDD System [1] Comparison competitor (System 2) vs. Ganser CRS (System 3) Pressure histories in accumulator during injection Injection pressure of System 3 with WDD is 280 bar or 20% higher and fully utilizes the pressure level generated by the HP pump [1] ASME-ICEF 2006, Paper # 1521

12. Ganser CRS with WDD and HP pump (design stage) The Injectors have individual accumulators The WDD system allows unidirectional pressure wave propagation to enhance the injection rate shape

13. Ganser CRS with WDD and HP pipes (Realized HW) The WDD system allows the use of either a CR HP pump or of the single jerk pumps available on an existing engine 6 cylinder inline system for 250-300 kW/cyl.
