Real-Time, Crank-Resolved Engine Simulation for Testing New Engine Management Systems

摘要

The development of control strategies for new Engine Management Systems requires a simulation tool to represent a model of the engine such that these strategies can be tested and verified. Current simulation tools for hardware-in-the loop (HiL) testing are limited to mean-value engine models. Although these lumped-parameter-type models are sufficient for current production Engine Management Systems, new technologies are emerging that would require sophisticated modelling tools to support the development of more complex systems such as closed-loop combustion control and for more thorough testing of onboard diagnostics. However, such hi-fidelity models have traditionally been distributed-parameter-typed models (e.g., WAVE), reserved for engine design purposes and therefore inappropriate for real-time testing.
