3.2 ADAPTORS AND DUMMY PLUGS
Adaptors and dummy plugs
GLOW-PLUG ADAPTORS
AVL glow-plug adaptors allow the use of probe-type sensors in standard and
custom tailored glow-plug bores. AG03 and AG04 can be customized down
to 5 mm tip diameters. The selection of the adaptor type depends on the
thread diameter of the glow-plug bore of the engine: For threads down to
M10 AG03 adaptor is recommended. For threads of sizes between M10 and
M8 AG04 is the right choice. For smaller diameters down to 4.3 mm please
refer to the integrated glow-plug solution GH13G on pages 58 – 59.

A new design of a glow plug adaptor must be ordered separately with the
article TIAGDESA.01.
Glow-plug adaptor order form
To customize the adaptor to your specific application a detailed description of
the glow-plug bore is required. To ensure the best performance and durability
of the delivered sensor especially the bore dimensions and length are important
for optimum design. AVL requires a full description of the custom tailored
adaptor. The glow-plug order form allows a clear specification of all required
dimensions. Based on this data AVL can design the adaptor to the customer
needs. The data is stored in the AVL database for further orders. The input as
well as forwarding the form can be carried out electronically. Please see page
130 for drawings with the required dimensions. The order form is also available
as download at www.avl.com/sensors.
