The oil box with corresponding parts and exhaust pipe were fixed to the oil system of FK6-1000 DTY machine,which assures the oil flowing better.

The fuel tank is improved to prevent fuel tank from leaking effectively when an accident occurs and the fuel tank is damaged.

Aimed at the motorcycle fuel tank forming process, using the numerical simulation software, it is studied on the strain/stress character and the influence of the major technologic parameter on its thickness variation.

This article, as the research object with the flow field in the fuel tank which is swirling by symmetry axis, adopting VOF discrete phase model and donor-acceptor method to analyze and simulate it.
