| 中文摘要: |
| 在总结我国高原气候和地理环境特点的基础上,从反映车辆动力性能的指标出发,以加速时间、最大爬坡度和最高车速入手,理论分析了对整车高原动力性影响较大的因素,主要包括有效热效率、循环喷油量、滚动阻力系数、空气密度对空气阻力的影响等。 通过分析高原环境对这些因素的影响,总结出了高原环境对车辆动力性的影响机理,并进一步提出了整车高原动力性改进的技术措施,认为先进增压、燃烧优化、高压共轨燃油喷射、高原环境标定、热平衡控制和富氧进气燃烧等技术措施成为提高车辆动力性的有效技术措施。 |

| Based on summarizing characteristics of climatic and geographical environment, the factors which affect dynamic performance of vehicles characterized by acceleration time, maximum gradability and maximum vehicle speed evidently were analyzed theoretically, which included effective thermal efficiency, fuel delivery per cycle per cylinder, coefficient of rolling resistance and effects of air density on air friction, etc. The mechanism of plateau environment on power performance of vehicles were got by analyzing the impacts of plateau environment on these factors. Then technical measures to improve plateau power performance of vehicles were put forward. Advanced turbocharging technique, combustion optimization technique, common rail fuel injection technique, plateau environment calibration technique, heat balance control technique and oxygen-enrichment combustion technology were deemed to be effective measures to improve power performance of vehicles in plateau. |
