| Outline of Final Research Achievements |
This study proposed the combustion control method using variable compression ratio mechanism for dual fuel engines with natural gas and gasoil. In this method, a low compression ratio is adopted to promote flame propagation under high load condition. And, a high compression ratio is adopted to promote premixed charge compression ignition under low load condition.
As the results of experiments using a rapid compression and expansion machine, we indicates the strategy for the determination of operation parameters such as compression ratio, exhaust gas recirculation, and gasoil injection-timing to obtain the high thermal efficiency together with low combustion noise and low exhaust emission for low and medium load condition.
