| Abstract: | As the mean-value engine model can not express the differences between cylinders and the corresponding precision is not high enough to satisfy the strict emission laws, this paper presents a cylinder-by-cylinder fuel-injecting model based on the vector rotator coordinate by taking the single-fuel LPG engine as the object, and then proposes an equation to describe the fuel injection of the six independent cylinders of a 6102LPG engine in a fuel life cycle. Experimental results show that the proposed model can accurately estimate the fuel charge of each cylinder, and that the precision satisfies the application requirements well. |
