Some sub-models of the original KIVA code were modified, by introducing into the Kelvin-Helmholtz and Rayleigh-Taylor model for spray breakup, the multiple laminar and turbulent characteristic timescale combustion model, the heat transfer model of Han and Reitz, the Hiroyasu and Nagle soot model and the improved Shell auto-ignition model were added to the original KIVA, to improve the predictions of engine spray, ignition, combustion, gas/wall heat transfer and emissions.

为提高模拟精度对标准的KIVA程序进行了改进，引入KH-RT雾化模型、层流和湍流多重特征时间尺度燃烧模型、Han和Reitz传热模型以及Hiroyasu和Nagle碳烟排放模型来模拟柴油机多次脉冲喷雾、燃烧、壁面传热及排放过程，同时增添改进的Shell自燃模型来模拟着火过程。

The results show that the microstructures of these three kinds of coating are different from those of the matrix (20 steel). The wear resistance of the flame spray coating is 4. 9 times that of the matrix. This is caused by the existance of hard noncrystal microparticals. The wear resistance of the coating by flame spray welding is 6. 3 times that of the matrix. The reason is that the fine crystal grains can be formed and the solution strengthening, dispersion hardening can be induced by these alloy elements. The resistance of the laser remelt coating is 8. 8 times that of the matrix. This is due to the solution strengthening, dispersion hardening and the existence of very hard dendritic crystal, eutectic and martensite in the microstructure.

作者指出，喷涂层由于层内有一定数量高硬度的合金非晶质点存在，其耐磨性是钢基体的4.9倍；喷熔层内合金晶化产生的晶粒细小，合金元素能起固溶强化作用，也能生成化合物产生弥散硬化作用，故此耐磨性是钢基体的6.3倍；激光涂敷层除所含合金元素产生的固溶强化和弥散硬化作用外，表层组织为高硬度的枝晶+共晶和马氏体，故其耐磨性是钢基体的8.8倍。
