ENGINE TEST SYSTEM
Railcar Engine Test System, RETS, based on the P2400 dynamometer
is suitable for the "In Chassis" testing of a range of diesel
engines including those fitted to the Class 14X, Sprinter150,
153, 155, 156, 158,and 159 railcars. Systems can be supplied for
engines up to 1500 BHP utilising our P4000 dynamometer.
It enables operators to fault-find, determine smoke and emission
levels or undertake diagnostic work without removing the engine
and or gearbox from the chassis while the engine is under load.
To undertake such work at present, the railcar has to be taken
"On-Route" to simulate operating conditions and even then it is
difficult for the testers to fully load the railcar. The adjustibility
of the support frame allows the dynamometer to be fitted between
the gearbox output flange and railcar differential pinion input
The dynamometer assembly is mounted on the hydraulic support trolley
and placed on the floor of a service pit. Horizontal slider plates
are extended outwards and bolted to the rails. The water supply
is connected from the tank and the supply pump via the mechanical
load control valve to the dynamometer inlet ports. Increasing
water flow increases the load the dynamometer exerts on the engine
and vice versa.
The basic system comprises the following major components.
P2400 dynamometer is mounted in double trunnions fixed to two
vertical end support plates. The end support plates are connected
to a horizontal connecting plate complete with two slider plates
for bolting to the rail.
hydraulic support trolley for lifting the above assembly.
P15 EDA computer based data logging system or any other instrument
from the PIPER range of instrumentation.
output adapter suitable for connection to the dynamometer cardan
water system including supply pump.
