Read Cylinder Head Temperature
– CHT – under the spark plug nearest to the exhaust on the
hottest cylinder.
An EGT gauge is not included as standard equipment on the Jabiru engines, though a system
can be supplied as an option.
Note: When testing an engine installation which differs from a typical Jabiru Aircraft
installation (even if only by the type of propeller used), the use of EGT sensors on each
cylinder is essential to ensure that all cylinders are receiving correct fuel/air mixture in all
modes of operation.
