14.4 RECOMMENDED GAUGES
The following measuring gauges should be available in order to carry out the above tests:
■
Digital electronic rev-counter, for example, a piezoelectric transducer to apply to injection pipes,
with a reference scale of 6000 rpm
■
Thermocouples to measure water, air, lubricant oil and exhaust gas temperature, for example, a
KPt/Pt-Rh type, able to measure up to 800º C.
■
Thermocouple digital reader, compatible with the fitted thermocouples assembly.
■
Pressure gauge to detect the air suction vacuum and the exhaust back-pressure; the typical ones
are the column-type gauge or mercury pressure gauge, the mechanic analogue one, the digital elec-
tronic one, with the following corresponding scales: from 2000 to 3000 mm H
2
0; from 150 to 250
mm Hg; from 200 to 300 mbar
■
Pressure gauges to measure the supercharging air and coolant pressures; they can be the mechan-
ic analogue-type or digital electronic-type, with a scale from 2 to 3 bar.
■
Pressure gauges to detect the engine lubricant oil pressure, usually the mechanic analogue-type,
with a scale of 10 bar.To measure the reverser oil pressure, the scale must be of 20 bar.
■
Sprit level / sight to measure the engine and vessel pitch.
■
Doppler effect tachometer to measure the vessel speed or a GPS to take measurements indirect-
ly in combination with other navigation data.
If engines fitted with EDC system are to be tested, the use of diagnosis instruments supplied by IVECO
is highly recommended. These instruments are able to measure temperature, rotation rate and fuel
injection values as well as many other values by analysing the data processed by the Electronic Unit and
gathered by means of sensors and transducers fitted in the installation.
