xDischarging is confined under specific EGR ratio, and the research carbon smoke exhaust that also shows the low-temperature burning process to EGR lead change very sensitive, in EGR at high proportion zone (approximately 50%), EGR leads the sharply increase that tiny variation (leading variation as 1%EGR) might cause carbon smoke exhaust, has enlarged markedly the difficulty that burning is controlled.In addition, in the zone of EGR at high proportion, although soot and discharged nitrous oxides all are close to zero, fuel economy significantly worsens, and generates a large amount of HC and CO and discharges.As seen, low temperature combustion mode is NO in the diesel engine traditional combustion
xEliminate with the trade-off relation of soot, still but brought the new compromise difficult problem of soot and fuel economy.
