摘 要

迫于现代社会的严重的环境污染与能源危机，实现社会的可持续发展，降低车辆排放与新能源汽车日益成为现代汽车工业的主要发展方向之一，混合动力汽车适应时代的需求，为众多车企所采用。所谓混合动力汽车HEV（Hybrid Electric Vehicle）,就是将一种或多种能量转化技术（如发动机、燃料电池、发电机、电机）和一种或多种能量储存技术（如燃料、电池、超电容、飞轮）集合于一体。这种混合动力汽车既发挥了发动机持续工作时间长、同时具有良好的动力性，又利用了电动机无污染、噪音低的长处，二者“相辅相成”，取长补短，可以提高10%的汽车热效率,同时改善废气排放高达30%.。

随着各国汽车排放法规的日趋严格和混合动力汽车的性能的日益提高以及其成本的不断的降低，混合动力汽车的市场份额也将不断增大，已成为本世纪前20年重点发展的新型汽车。

本文以长安杰勋混合动力汽车为研究对象，对长安混合动力汽车在综合工况下进行理论与实验分析研究，同时在ADVISOR仿真软件的基础上进行试验与仿真的对比性研究。主要内容包括：

（1）分析汽车污染物排放的产生原理及危害和汽车发动机燃烧排放的控制方法与措施；

（2）研究了解各种汽车排放污染物的产生原理和影响的原因，创建发动机的燃烧与排放模块，研究仿真在不同工况下的排放的情况；

（3）分析了解不同混合动力汽车的结构形式和动力传递路径及各自的控制策略的模型。

（4）基于ADVISOR2002仿真软件平台，对长安杰勋混合动力汽车建立模型，仿真分析在综合工况下的长安杰勋混合动力汽车在不同的条件下排放性的变化情况；同时结合试验研究，完成仿真结果与理论数据的差异性分析，为杰勋混合动力汽车的排放研究提供一定的理论和试验

研究基础。

ABSTRACT

Under the serious environmental pollution and sources crisis of contemporary society , achieving sustainable development ,the development of new energy cars and efficient cars has become the development direction of the automotive industry. Hybrid electric vehicle is adopted by many auto enterprises for its adapting the trend of time. Hybrid electric vehicle combines one or several kinds of energy transform technique(engine, fuel cell, generator, dynamo etc.) with another one or several kinds of energy transform technique(fuel, battery, super capacitor, flywheel).It can not only exert the engine advantage-long work time and good power performance, but also exploit electromotor’s pollution free pesticide and quiet noise. Both work together and learn from others's strong points to offset one's weakness. It can enhance more the 10 percentage of car heat efficient(more than 30 percentage for urban public transport)and more than 30 percentage of exhaust gas.

By the increasing strict emission laws around many countries and HEV increasing power performance and its increasing cost descend , HEV will take more and more market share, becoming the important new autostyle at the first 20years of 21century.

In the dissertation ,the Chang’an Jiexun HEV is researched and tested on its emisson and performances within the ADVISOR2002 about simulation software of hybrid electric vehicle under the typical drive conditions. the simulation and theoretical analysis have been completed. The main contents include:

1. Analysis of harmful pollutions of vehicle engine, the methods of controlling emission is discussed and the development of basic vehicle emission technology is expressed.
2. Analysis the combustion model of vehicle engine and emission model of vehicle, formation principles and affecting factors of pollutant about
3. CO、HC、NO_X and the trends and the condition of emission pollutant on different drive cycle condition are discussed and researched. These will provide a theoretical basis for Chang’an Jiexun HEV
4. It is discussed to analyze of the construction 、power transmission and control strategy of HEVs .
5. Through analysis ofADVISOR2002 simulation software, the Chang’an Jiexun HEV model is esttablished.. Using the simulation model in Advisor simulation software, the Chang’an HEV in the different typical drive cycle and condition under different control strategy are analyzed and researched. The different simulation and experimental results are analyzed and discussed. In a word, the theoretical analyses and simulation of emissions control for Changan HEV is discussed and researched in the paper, which provides some theoretical reference for emissions control of the HEVs.
