fter the debugging of the injector flow, flow-up column components of injector must conduct the top stop debugging and trip debugging.STC type and high-pressure injector in the future all have flow-up column. After completing the injector leak test ,,the injector can be assembled to the debugging instrument to conduct the tappet top stop debugging or tappet trip debugging. Taking out the injector tappet, installing the elastic cushion and spring, reassembling the tappet, then the debugging is done.

PTXW debugging instrument can be used to conduct the tappet top stop debugging and trip debugging or flow-up column top stop debugging and trip debugging.
