Abstract
There is given a method and a technology for restoring operating capacity of pump-injectors and individual pumps for diesel engines taking into consideration cost indices of particular spare parts. Studies were conducted on pump-injector kits produced by different foreign companies. The method supposed is based on the evaluation of electromagnetic valve air gap by operating and drop-out currents of this valve without using a fuel test stand. There was practically evaluated the recoverability of starting values of electromagnetic valve stroke and air gap by operating and drop-out currents, and the efficiency of restoring them in pump-injectors and individual pumps for diesel engines. There were found the average values of operating and drop-out currents, and deviations of them from the average parameter, as well as those for valve air gaps for pump-injectors of a kit. The pump-injector tester TNF-1 was used for carrying out this work. Due to the preliminary recovery of the electromagnetic valve operation without using the fuel test stand, the method suggested makes it possible to cut time for repairing a kit of pump-injectors and individual pumps by as much as 3 times. The comparison was made between this method and the generally accepted one, when repair quality is tested on the test stand by measuring fuel cycle deliveries.
