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。
The test and calculation methods provided in this paper are designed to optimize the fuel economy within a given multi-condition operating specification to meet the required emission standards and performance losses to provide the best possible fuel economy, This economy is through the impact of significant ignition advance angle and air-fuel ratio variable adjustment, automatic test bed by the internal combustion engine to collect a large amount of data and the application of computer technology to optimize the regression of these data, the use of dynamic programming theory of vehicle simulation results And it is the optimal compromise between emissions and fuel economy.
