【摘要】 本文介绍了三种模拟发动机排气温度的方法,着重论述基于模型与数学统计模权电控发动机排气温度的方法,主要对氧传感器和三元催化转化器处的温度进行了模拟。实验数据与真实排温进行对比,误差保持在工程误差范围内,表明该模型能较精确地模拟发动机的排气温度。更多还原

【Abstract】 Three methods for modeling engine exhaust temperature are introduced.Then emphasize a method modeling electronically-controlled engines’ exhaust temperature by means of the combination of modeling and statistical fitting.Mainly model the temperature at oxygen sensor and three-way catalytic converter.Compare the modeled temperature with the real ones and error keeps in range of engineering measurement error.Then prove this method can model engine’s exhaust temperature accurately.更多还原
