摘要翻译：
提出了一种发动机温度的计算方法。重点研究了燃烧室内部的瞬态和散射边界条件，包括燃烧和滑行条件，以及水套的动态传热。模型约简是通过量纲分析和概率密度函数的应用来实现的，这允许时间尺度的分离。采用静态缸内压力测量作为输入值，并根据瞬态行为，用自己的部分负荷模型进行修正。一台涡轮增压SI race发动机在燃烧室附近的不同位置配备了70个热电偶。与已有文献不同的是，该方法处理的是发动机在一圈比赛过程中的瞬态行为，其频率范围为0.1-1 Hz。这包括在齿轮变化、扭矩变化或从点火到滑行条件的过渡下发动机速度积累。成功地模拟了不同测量位置的不同热行为。此外，还可以预测不对称点火顺序和不等残馀气体下不同容积效率对气缸温度的影响。水套的能量平衡达到了几个百分点，并且能够准确地模拟进水温度的变化。

英文摘要：
  A calculation method for engine temperatures is presented. Special focus is placed on the transient and scattering boundary conditions within the combustion chamber, including fired and coasting conditions, as well as the dynamic heat transfer of the water jacket. Model reduction is achieved with dimensional analysis and the application of probability density functions, which allows for a timescale separation. Stationary in-cylinder pressure measurements are used as input values and, according to the transient behavior, modified with an own part-load model. A turbocharged SI race engine is equipped with 70 thermocouples at various positions in proximity to the combustion chamber. Differentiating from already published works, the method deals with the transient engine behavior during a race lap, which undergoes a frequency range of 0.1-1 Hz. This includes engine speed build-ups under gear changes, torque variations, or the transition from fired to coasting conditions. Different thermal behaviors of various measuring positions can be simulated successfully. Additionally, cylinder individual temperature effects resulting from an unsymmetrical ignition sequence and different volumetric efficiencies with unequal residual gas can be predicted. Up to a few percent, the energy balance of the water jacket is fulfilled and variations of water inlet temperatures can be simulated accurately enough.
