1.气缸盖罩壳处发出“的、的”响声,且响声次数有规律地随柴油机转速的增高而增多,随转速的降低而减少,基本上是曲轴转两转发出一二次响声。产生这种响声有两种原因,一是气门间隙过大,应重新将进气门间隙调整为0.35毫米,捧气门间隙调整为0.45毫米。二是气门杆与气门导管配合间隙或气门摇臂衬套与摇臂轴间隙过大所致。S195柴油机气门杆与气门导管配合极限间隙为0.30毫米,气门摇臂衬套与摇臂轴的磨损极限为0.20毫米。更换新件后,响声消除了。 2. 气缸内时而发出几声大而尖的“嗒、嗒”声,随着敲击声冒出一股浓黑烟。这种响声大多因为气门导管下部断裂,且断裂部分随气门上下运动发生撞击,撞碎的碎片和
1. The cylinder head cover emits “,” sound, and the number of beeps increases regularly with the increase of the engine speed, decreases with the decrease of the speed, basically the crankshaft turns two times and sends out one or two noises . There are two reasons for this sound, one is the valve clearance is too large, should re-adjust the intake valve clearance 0.35 mm, holding the valve clearance is adjusted to 0.45 mm. Second, the valve stem and valve guide with the gap or valve rocker arm bushings and rocker shaft clearance is too large. S195 diesel valve stem and valve guide with the limit clearance of 0.30 mm, valve rocker bushing and rocker shaft wear limit of 0.20 mm. After the replacement of new pieces, the sound disappeared. 2. Sometimes the cylinder made a few big and sharp “Dada, click ” sound, with the percussion sound of a thick black smoke. Most of this noise because the lower part of the valve guide rupture, and the fracture part of the valve up and down the collision, crashed fragments and
