Since high carbon alloy steels is HRC 55~65 in hardness and 1.5%~2.5% in Carbon Equivalent, high-carbon-alloy-steel surfaced metals generally were selected in order to maintain high hardness and wear resistance of weld repaired layer, of which high-carbon Cr-Mo-W surfaced metal had been most widely used with 300~500℃ preheat or heat-treat after welding to improve its crack resistance.

由于高碳合金钢的碳当量高达1.5％～2.5％，硬度一般为HRC55～65，为了保证修复层的高硬度和耐磨性，焊接材料常选用高碳合金钢质堆焊金属，目前最普遍采用为高碳Cr－Mo－W系堆焊金属，但必须采用350～500℃高温预热焊和焊后热处理工艺措施以保证其具有一定的抗裂性。

The effects of port injected n-heptane equivalence ratio and iso-octane direct injection timing are investigated experimentally and numerically. The results indicate that the combustion mode of iso-octane is dependant on the iso-octane direct injection timing corresponding to the stage of n-heptane HCCI combustion. In case of direct injection before the low temperature reaction of n-heptane, premixed combustion of the iso-octane occurs. In case of direct injection at the NTC period or the initial high temperature reaction stage of n-heptane, the iso-octane mainly undergoes premixed combustion.
