Research and Design of Small-engine LPG Motorcycle Fuel System

摘要

By the analysis and comparison of LPG motorcycle and LPG automobile, the similarities and differences of them are expounded. Based on the components and structure of LPG automobile fuel system, the LPG motorcycle gas phase positive pressure fuel system and LPG motorcycle liquid phase positive pressure fuel system are designed, and the advantages and disadvantages are analyzed and compared. The engine cylinder cover is enhanced and setted maze channels, so the liquid state LPG can be pre-heated using the remaind head of engine before enter the decompressor, the frozen of decompressor is solved effectively. The road trial and testing show that the LPG motorcycle liquid positive pressure fuel system is simple in structure, stabilize and reliable, the comprehensive performance can satisfied the demand of national standard.
