| Abstract: |
| 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. |
