CYLINDER HEAD TEMPERATURE
Cylinder head temperature (CHT) for all four cylinders are shown on
the LEAN page. The cylinder with the hottest CHT is indicated by a
cyan bar graph. The indicator range is from 100°F to 500°F with a
normal operating range from 200°F to 500°F and a warning range (red
line) at 500°F. When the CHT is 500°F or hotter, the bar segments,
CHT label and °F digital value will change to red to show that the CHT
is greater than the limit.
A thermocouple is installed in each cylinder head and provides a signal
to the engine display that is processed and shown as CHT on the EIS
LEAN page. The LEAN page will show a red X over any cylinder that
has a probe or wiring failure.
EXHAUST GAS TEMPERATURE
Exhaust gas temperature (EGT) is shown on the ENGINE page by the
EGT horizontal indicator. The indicator range is from 1250°F to 1650°F
with graduations every 50°F. The white pointer indicates relative EGT
with the number of the hottest cylinder displayed inside the pointer. If a
cylinder EGT probe or wiring failure occurs for the hottest EGT, the next
hottest EGT will be displayed.
The EGT for all four cylinders is shown on the LEAN page of the EIS.
The hottest cylinder is indicated by the cyan bar graph. The EGT for a
particular cylinder may be shown by using the CYL SLCT softkey to
select the desired cylinder. Automatic indication of the hottest cylinder
will resume a short time after the CYL SLCT is last selected. The LEAN
page will show a red X over a cylinder that has a probe or wiring failure.
A thermocouple is installed in the exhaust pipe of each cylinder which
measures EGT and provides a signal to the engine display that is
processed and shown as EGT on the EIS LEAN page.
