1.前言因摩托车的发动机重量占整车总重的比例大,所以发动机的性能对摩托车的动力性能、操纵稳定性等有很大影响.研制小型、轻量的高功率发动机,在任何时代都是最重要的目标.但自确立排气法规技术后的今天,进一步加快了汽油机的高性能化,低油耗化.另外,随着用户需要的多样化,研制出了从实用的购物车到旅游的运动车使用的各种类型发动机.本文分析了提高上述发动机性能的技术,并选择其中较成熟的具体技术作一介绍.
1. INTRODUCTION Because the engine weight of motorcycles accounts for a large proportion of the total weight of the vehicle, the performance of the engine has a great influence on the dynamic performance and steering stability of the motor vehicle, etc. The development of small and lightweight high-power engines, The era is the most important goal.But since the establishment of exhaust regulation technology today, to further accelerate the high performance of gasoline engine, low fuel consumption.In addition, as the user needs diversification, developed from the practical shopping cart To travel the sports car using various types of engines.This paper analyzes the technology to improve the above engine performance, and select one of the more mature specific technology to make an introduction.
