摘要

将克兰贝生物柴油与沼气相结合，可作为内燃机的可再生能源。因此，在双模式(沼气)和正常模式(生物柴油)下，对crambe生物柴油混合物(B0, B10, B30, B50, B75和B100)的排放和发动机性能进行了评估。试验是在一台5kva发电机发动机上进行的，负载范围从1到4 kW。正常模式下的功率比双路模式下的功率低17%。双模式显示出比正常模式更低的油耗。在正常模式下，随着生物柴油比例的增加，功率损失也随之发生。此外，氮氧化物排放量随着沼气的添加而减少。在双模式下，随着生物柴油含量的增加，排放量增加。两者的一氧化碳排放量都有所下降

COMPARISON OF EMISSIONS AND ENGINE PERFORMANCE OF CRAMBE BIODIESEL AND BIOGAS

The combination of crambe ( Crambe abyssinica L.) biodiesel and biogas could be a renewable energy alternative for internal combustion engines. Therefore, the emissions and engine performance of crambe biodiesel blends (B0, B10, B30, B50, B75, and B100) were evaluated in both the dual mode (biogas) and normal mode (biodiesel). The tests were performed on a 5-kVA generator engine at loads ranging from 1 to 4 kW. The power generated in the normal mode was 17% lower than that generated in the dual mode. The dual mode showed a lower specific fuel consumption than the normal mode. In the normal mode, loss of power occurred as the proportion of biodiesel increased. Furthermore, nitrogen oxide emissions decreased with the addition of biogas. In the dual mode, the emissions increased as the biodiesel content increased. Carbon monoxide emissions decreased in both
