摘要
本文所提供的试验和计算方法旨在满足规定的排放标准和性能损失最小的情况下，在给定的多工况运行规范内对燃料经济进行优化，从而提供尽可能最佳的燃油经济性，这一经济性是通过影响显著的点火提前角和空燃比的变量调整，经内燃机自动试验台对大量的数据进行采集并应用计算机技术对这些数据进行优化回归，使用动态规划理论对车辆模拟计算结果而得到的，它是排放和燃油经济性矛盾的最优折衷选择。
he trials and the calculating methods proveded by this article aim to optimizefuel economy and offer the best fuel economy as far as possible. At the same time, within therunning parametes of multi-behaviours, the results must satisfy the specified emission standards and the loss of performance is the least. Fuel economy is gotten by adjusting the ignition advance and air /fuel ratio, collecting lots of data with the automatic engine test bed, optinizing regress this data with computer, and using the therory of dynamic programming tocalculate and simulate the vehicle. The best point is the compromise between the conflictinggoals of emissions and fuel economy.
