Development of Biogas-Diesel Engine for Farm Use (Part 3)

Robustness of Optimized Biogas Supply Schedule

Abstract

In our research a dual-fuel diesel engine was operated with biogas and diesel fuel. The performance of the engine was able to be increased by optimized scheduling of Biogas supply to the engine by using a buffering tank. In this method, it is assumed that the profiles of biogas production and the engine load are fixed every day. But it is expected that these profiles are changing every day. Therefore, the declaration of the engine performance caused by such fluctuation was evaluated. The fluctuation of biogas production profile had almost no effect on the engine performance, but had more effects on engine load. But in many cases, the declaration of the performance were not so significant. Therefore the optimized schedule of Biogas supply has the robustness against the fluctuation of the operating situation.
