This article is the author through scientific research and teaching practice experience, some of the characteristics of multi-column engine made a more systematic analysis.There are three issues in the paper.1.Multi-column engine cylinder layout scheme: how to put forward A simple way to determine the arrangement of the cylinder, put forward the uniform firing interval can be used as the starting point of design.This paper lists the combination of graphic method and several sets of formulas, in order to facilitate the design .2. Multi-column engine firing order: introduced Select the order of ignition generally considered factors, and the order of the engine firing law was introduced in order to facilitate identification.3.Multi-column engine balance analysis: In the paper forward and reverse vectors as a starting point for the balance analysis , Analyzes the relationship between the V-type engine and the cylinder angle variation and its balance characteristic analysis method, and leads to the general formula of the integrated forward vector and the comprehensive reverse vector of the V-type, the X-type and the star type engines. Second, the design of multi-cylinder engine cylinder layout program Ⅰ. General outline Ⅱ.Determine a number of factors in the layout of the cylinder Ⅲ. Meet the firing interval uniform conditions IV. Multi-cylinder engine cylinder Examples of Layout Proposals Ⅴ. Star-type Air-cooled Engine III. Ignition Sequence of Internal Combustion Engine Ⅰ. Factors to be Considered in Propagation Sequence Ⅱ. Sequence of Ignition Sequence IV. Balance Analysis of Multi-Column Engine Ⅰ. General Description Ⅱ. Ⅴ type engine balance analysis Ⅲ.X type engine balance analysis Ⅳ. Star type engine balance analysis V. Conclusion
