1.3.1 Cylinder Head Temperature
Cylinder head temperature (see Table 1.5-1) is measured at the spark plug. A ring-shaped
thermal element placed under the spark plug is screwed in with it. The placement of the
thermal element is of great importance. The connecting cable of the thermal element should
be led upward behind the spark plug in such a way that the cool air stream does not blow on
the connection of the ring-shaped sensor.
Only
calibrated sensor devices
should be used.
Notice that measuring cables that have later
been made longer between the thermal element and the measuring device may falsify the
reading.
Temperature measuring devices with lengthened cables have to be recalibrated
at time of installation
.
Defective or improperly working thermal elements, temperature gauges, and measuring cables
have to be replaced immediately.
The maximum acceptable cylinder head temperatures mentioned by Göbler-Hirth
Engines are based upon the proper positioning and calibration of the measuring devices
within the range of these temperatures.
1.3.2 Exhaust Gas Temperature
The exhaust gas temperature
(see Table 1.5-1)
is measured individually for each cylinder at
the exhaust bend [manifold]. An exhaust bend that is prepared for installation of thermal
elements may be ordered from
Göbler-Hirth Engines.
A staff-shaped thermal element will be pressed into a special sealing screw joint.
Of great importance is the installation position of the thermal element. The thermal element
must be pushed into the exhaust bend deep enough so that its point is in the middle of the
exhaust bend pipe [manifold].
Only
calibrated measuring devices
should be used. Notice that measuring cables that have
later been made longer between the thermal element and the measuring device may falsify the
reading.
Temperature measuring devices with lengthened cables have to be recalibrated
at time of installation.
Defective or improperly working thermal elements, temperature
gauges, and measuring cables have to be replaced immediately
.
The maximum acceptable exhaust gas temperatures mentioned by Göbler-Hirth
Engines are based upon the proper positioning and calibration of the measuring devices
within the range of these temperatures
