Tóm tắt
The article focuses on researching and evaluating the effect of knocking in biomethane/diesel dual-fuel operating modes. Knocking occurs because part of the biomethane fuel is compressed at high temperatures and pressure. All experiments were performed on four-stroke Cummins diesel engines with an AC_STAG electronic control unit operating in dual-fuel mode. The system is installed with Ac dyno-measuring devices and other pressure, temperature, and emission-measuring devices. By the Knock Peak method used in the AVL Indicom software, high-pressure analysis during fuel combustion showed knocking in the cylinders. The maximum pressure deviation is also known as the knock peak value (KNK_PK). Knocking can be observed at dual-fuel mode with different pressure curves, which are higher than in diesel. The CoV coefficient of dual-fuel operation is higher than that of CI engine diesel fuel operation. The knock limit of biomethane/diesel dual-fuel has been shown in this study.
