Future Prospects for Supercharging

This paper proposes a new flexible system concept applicable to diesel engines which will achieve the compatibility of high BMEP (Break Mean Effective Pressure) and low fuel consumption. The high BMEP means constant power from low speed to high speed (the power density will be 60ps/liter for truck applications, 87ps/liter for marine applications and 109ps/liter for racing boats). BMEP will be over 32kg/cm2. The low fuel consumption means a wide range of speed and torque having a good match to the best turbocharger efficiency. Before feasibility testing of an engine a basic simulation has been done and is introduced in this paper.
