整车发动机选型匹配及实例分析

The Vehicle's Engine Lectotype and Example Analysis

分析了拟开发车型动力总成选型的基本方法。为了保证整车动力性、经济性及噪音达到预期的设计目标,整车可靠性、寿命及环保等都能更好地满足客户的需求,发动机选型一定要考虑全面。分别通过发动机选型基本流程、理论计算、数模及实物搭载等步骤,分析确定几种备选方案,根据各种方案的优缺点情况再确定最终的备选方案。本论文为以后其他产品的开发提供了参考。

The method for engine lectotype of vehicle to be developed is analyzed.To make sure the vehicle＇automobile dynamic quality and economical efficiency can achieve the required value,contemporaneously the vehicle＇authenticity,durability,environmental protection and so on can satisfy customers demand,the engine lectotype must be considered comprehensively.In this paper,several alternative plans were confirmed by engine lectotype procedure,theoretical calculation,module and practice loading ect.Then the best programmer can be determined by comparing the merits and drawbacks.This paper can afford bases for other production.
