GLOW PLUG CONTROL UNIT (DIESEL

VEHICLE ONLY)

LOCATION

The Glow Plug Interface Unit mounted on water

channel RHD

OPERATIONAL DESCRIPTION

The aim of Glow Plug Interface Unit (GPIU) is to

achieve high degree of flexibility in driving the

glow plugs that are included in a standard EMS

system for diesel engines. It is evident that the

requirement for GPIU depends from the driving

characteristics required by the glow plugs.

In a modern direct injection diesel engine the

function developed by glow plug may be

summarized as follows:

Auxiliary starting device

Cold diesel engines due to high levels of internal

frictions & thermal losses are reluctant to start.

Often need of auxiliary devices like glow plugs are

the only method to guarantee engine start. The

glow plug power dissipation increases the

combustion chamber temperature allowing the air

fuel mixture to reach its self-ignition condition.
