    摘要： During operation of a single-cylinder test engine, a computer or other processor runs a simulation of additional “virtual cylinders” operating alongside the single cylinder as if all cylinders, real and virtual, were present in a real multi-cylinder engine. Temperature data from the virtual cylinders is generated, and the real cylinder is jacketed with flow passages which are supplied with heat transfer fluid at temperatures such that the thermal presence of the virtual cylinders adjacent the real cylinder is simulated. As a result of this thermal simulation, the real cylinder is able to more accurately simulate the performance that it would have if it was indeed present in a multi-cylinder engine.

    摘要翻译： 在单缸测试引擎的运行期间，计算机或其他处理器运行模拟与单个气缸一起运行的附加“虚拟气缸”，就好像真实和虚拟的所有气缸都存在于真正的多气缸发动机中一样。 产生来自虚拟气缸的温度数据，并且实际气缸被带有流动通道的流动通道，该通道在被模拟与虚拟气缸相邻的虚拟气缸的热存在的温度下被供给传热流体。 作为这种热模拟的结果，真实气缸能够更准确地模拟如果确实存在于多缸发动机中将具有的性能。
