(5) the discharge throttle inspection

To check diesel engine throttle valve discharge, should be ready to speed table, and appropriate stopwatch timer. Transmissions to a free, separate clutch, throttle full, in the most high-speed diesel engine idling. Then, suddenly open up the throttle or throttle moved to the closed position, and start the stopwatch. When the diesel engine speed of 1000 r / mm, stop and pay attention to the stopwatch deceleration time, repeated several times measured.
If high-speed diesel engines idling from the slowdown after the stall (at the governor control idling diesel engines), will inevitably increase the throttle valve discharge. This can be adjusted into the fastening screws (only fixed throttle screw), the diesel engine deceleration time increased s 1-2. At this time, will be locking screw, a re-examination of Idle and, if necessary, re-adjustment.
If diesel engine deceleration slow, and should reduce the throttle valve to vent flow (prior to check-idling at the deceleration time). If this does not reduce the deceleration time, the throttle valve is not the problem if time greatly shortened, we must reduce the throttle valve discharge (rotary screw adjustment to check diesel engine deceleration. If diesel engines from the Idle speed reducer stall after another trend should continue screwed tightly onto the screw, deceleration time increased s 1-2. then screw locking. need to be adjusted in accordance with Idle).
