Characteristics of A-N Glow Plugs

Terminal & Shell
The outer casing and terminal are zinc coated to resist corrosion.

Insulator
The Glow Plug insulating disc has exceptional strength, insulation and
thermal conductivity to ensure that a short circuit cannot occur.

Casing
An alloy casing surrounds and protects the Glow Plug to provide heat
resistance.

Seal
A rubber seal is in place to prevent air from seeping through and
corroding the coil

Insulation
Electrical insulation of the coil is provided by firmly packed magnesium
oxide powder, which is also an efficient heat conductor

Regulating Coil
The main coil acts as a regulator within the Glow Plug to control and
sustain temperature rise, and ensure a rapid warm-up.

Coil Connection
Laser welding connects the Heating and Regulating coils to maintain
their position at all times and ensure consistent resistance characteristics.

Heating Coil
A shorter, tapered coil inside the end of the Glow Plug delivers a quick
start (from as little as 3 seconds) even in cold conditions. It can then
hold its post-heating temperature for up to six minutes after cold start.
This contributes to lower engine emissions.

Tip
The narrowed plug tip ensures improved heating efficiency and
excellent performance.
