Abstract

 

Due to varying in-cylinder conditions, cyclic combustion variation leads to fluctuating and deteriorated diesel engine performance. In this paper, we study both the deterministic and the stochastic cyclic variation of a closed-loop controlled combustion process with a cycle-to-cycle fuel injection controller using in-cylinder pressure information. A controller design method is proposed that yields a stabilizing controller with fast dynamical performance, while minimizing the unavoidable amplification of the stochastic cyclic variation. Following the design method with different design parameters, multiple controllers are designed and experimentally tested using a single-cylinder engine test setup. The reference tracking results illustrate the trade-off between the controllers’ capability to reduce the deterministic or to avoid amplification of the stochastic cyclic combustion variation.
