柴油机的燃烧过程通常分为四个阶段,即从柴油喷入气缸内到形成火源中心的着火落后期或称滞燃期;从形成火源中心到柴油迅速燃烧,气缸内压力上升到最高点的速燃期;从气缸内燃气压力达到最高点到燃气温度升到最高点为止的缓燃期;从燃气温度最高点到燃烧过程结束的补燃期。如果在燃烧期内,由于火焰迅速传播,柴油大量燃烧,气缸压力升高过快,当单
The combustion process of a diesel engine is usually divided into four stages, that is, from the injection of diesel into the cylinder to form the ignition center of the ignition lag or lag phase; from the formation of ignition source to the rapid combustion of diesel, the cylinder pressure rose to the highest point Of the flashover period; from the cylinder gas pressure reaches the highest point to the gas temperature rose to the highest point of the retarding period; from the highest point of the gas temperature to the combustion process at the end of the replenishment period. If the combustion period, due to the rapid spread of the flame, a large number of diesel combustion, cylinder pressure rise too fast, when a single
