6SD1 Diesel Engine Cylinder liner 1-11261300-0 1-11261368-2 For ISUZU

Processing processCylinder barrel: Blanking ---- rough car --- heat treatment (tempering) ----- car (flat head chamfering) ---- rough push inner hole--- rolling inner hole ---- car (outer circle open frame socket) ---- car inner hole stop ---- welding cylinder bottom ---- car (outer circle) There is also internal galvanizing or chrome plating as requiredExecution standardsThe production implementation standard of wet cylinder liner is GB/T1150-2010, and this standard applies to the wet cast iron cylinder liner of reciprocating piston internal combustion engine with a cylinder liner diameter of less than or equal to 200mm.The national standard of dry cylinder liner is still JB/NQ 56.1~56.3-87, and the general dry cylinder liner wall thickness is 4mm.

1. The oil supply time is too earlyWhen the piston of the diesel generator set does not move upwards to reach the specified fuel injection position, the injector begins to inject oil, so that the fuel combustion is advanced, and the high-pressure gas in the cylinder hits the piston, emits a rhythmic "click, click" crisp knocking sound, reduce the throttle, and the knocking sound is obvious.The elimination method is to adjust the fuel supply advance angle, that is, increase the gasket between the fuel injection pump and the gearbox to delay the fuel supply time to meet the specified fuel injection time. For every 0.1 mm increase in the gasket, the oil supply advance angle can be delayed by 1.3-1.7.2. Poor fuel burningToo low fuel injection pressure, oil dripping from the injector, poor atomization of fuel injection, and too late fuel supply time will cause poor fuel combustion and cause cylinder knocking. The knocking sound caused by such faults is muffled, hoarse and accompanied by engine overheating, black smoke or exhaust pipe cannon and fire. The injector should be removed for inspection and adjustment, adjust the fuel supply time, and replace it with new parts if necessary to make it comply with the regulations.
