WHAT IS A GLOW PLUG?
Diesel engines, unlike petrol engines which rely on a spark to ignite the air-fuel mixture, function due to the auto-ignition of diesel fuel when subjected to high pressures. Under high pressure, the temperature of the diesel fuel increases to a point where the fuel self-combusts. In cold weather however, this temperature is not always achieved and glow plugs assist by heating the air-fuel mixture to assist in cold starting.
Put simply, glow plugs are small heaters.
INSPECTION OF GLOW PLUGS
In order to check the heating coil or element, measure its resistance as shown in the diagrams (right) and based on your findings if;
- Resistance value ∞ : The heating coil/element is broken
- Resistance value of a metal glow plug is less than 5 ohm: The heating coil is in good condition.
Resistance value of a ceramic glow plug is less than 1 ohm: The heating element is in good condition
