摘要
原HS125GY车所配化油器为柱塞式PZ26,与普通两气门125 mL发动机相当,采用四气门设计的目的是要提高进气填充效率,但PZ26化油器实际上却限制了发动机的进气效率。应匹配大口径化油器、进气管、空滤器来提高进气效率空间,按RX125进气口等效直径匹配化油器、进气管和低阻力系数空滤器。
The carburetor equipped originally on the HS 125GY motorcycle was of plug PZ26 which is equal to that of ordinary twin-valve 125 mL engine. The purpose of adopting 4-valve design is to lift the intake charge efficiency. But the PZ26 carburetor actually restrains should be equipped to increase the intake efficiency space, and the carburetor, intake pipe and air filter with lower drag coefficient matching with the RX125 intake port equivalent diameter should be used.
