Detailed Product Description

The PT-200A is used for calibrating the Cummins PT injector that was used in series
N.K.10.M11 Cummins engine.

PT test bench features:
1. Digital reading of injector output directly, minimum individual 0.1cc
2. Clamping of the injector occurs with the camshaft stationary and in the "index"
position i.e. with the injector cam when at the "index" position is such that
the datum valve cam follower is at minimum lift which causes the datum valve to
be open by link, when the camshaft starters to turn the datum valve to close whist
the injector cam and tappet are still operating on top dwell. this locks the
position of piston rod and the injector body relative to the cambox leaving the
injector plunger free to be operated by the injector cam. The datum valve is opened
every time the injector cam is on the top dwell allowing both pressures in the
clamp chamber and the position of the injector and fixture relative to the cambox
to be corrected every cycle.
3. Using the fuel arm, operator can check and adjust flow of the injector it is unnecessary that unclamping the injector form the stand. This can assure the accuracy
and raise work efficiency.
4. The injector intake analogous device which analogize engine work.
5. The fuel temperature was controlled by the micro-computer.
6. The stand was controlled by PLC (programmable logic controller), the electrical
system is reliable.
7. The stand has many mechanical and electrical protection mechanisms that guarantee
safety of life
