As a result, by merely replacing the gasoline injector with natural gas injector, a large volume of natural gas is injected on the intake valve and then reflected, which makes the fuel concentration and pressure field in the intake manifold after the natural gas injection for the natural gas engine differ greatly from those for gasoline engine.

结果表明，若仅把MPI汽油机的喷油器用天然气喷射阀更换，大量的天然气喷到进气阀后反射，造成天然气发动机进气岐管内的燃料浓度场、压力场与MPI汽油机明显不同；并且进气阀被打开后，先期吸入气缸的天然气在纵向滚流的作用下被挤向进气阀底部下方，与后期吸入气缸的空气形成明显的分层充气构造。

To solve this problem,we present a method of self-intersecting manifold learning. The core of this method is to select neighborhood points based on tangent space clustering. We construct a layered neighbor-graph to storage the trusted information of low dimensional neighborhood.
