A novel approach to investigating advanced boosting strategies of future diesel engines

摘要

This paper describes the modelling of advanced air handling configurations using cycle simulation and a "black box" engine, design of experiments approach. The interactions between manifold pressures and temperatures, compression ratio and valve timing events are investigated and described. Optimisation of engine operating conditions for maximum torque and improved fuel consumption is discussed. Finally the development of novel boost system emulation hardware is described. The paper describes ongoing work to develop real time models of air handling components to integrate with the emulating hardware such that future technology combinations of supercharging, e-boosting and sequential turbo charging configurations can be rapidly evaluated in terms of both steady state and transient engine performance.
