(6)涡轮增压柴油机喷入气缸内的燃油量,是根据柴油机增压后进入汽缸内的空气量确定的。由于增压器转速变化存在惯性,因此,当发动机负荷由小变大时,增压器增压总是滞后一段时间,导致在这段时间里,供给的燃油量增多了,但供给的空气量并未相应的增加,这样,柴油机必然会因空燃比失调,燃油不能完全燃烧而排黑烟,既浪费了燃油又污染了环境,汽缸等还会因积炭增多而增加磨损。由增压压力控制的增压补偿器,是一种膜片式燃油量控
(6) The amount of fuel injected into a cylinder by a turbocharged diesel engine is determined based on the amount of air entering the cylinder after boosting the diesel engine. Because of the inertia of the turbocharger speed change, when the load of the engine increases from small to large, turbocharger pressurization always lags behind for a period of time, resulting in an increase of the amount of fuel supplied during this period, but the amount of air supplied Not corresponding increase, so that the diesel engine will inevitably due to air-fuel ratio imbalance, the fuel can not be completely combusted and black smoke, both waste of fuel and pollute the environment, cylinder will increase due to increased coke and wear. The boost compensator, controlled by boost pressure, is a diaphragm fuel gauge
