Glow Plugs

Reliability diesel engine drivers can count on

From the worlds No.1 spark plug manufacturer you’d expect nothing but the best from their glow plugs too; and you’d be right. Niterra have been relentlessly developing engine pre-heating technology since the early 1960s and the inbuilt advanced technology ensures that automotive engineers can get the most out of their engine designs and help them meet the increasing emission targets necessary to improve our environment.

Combining proven technology with continuous development

At low temperatures, well-performing glow plugs play an important role in supporting reliable engine starts. Glow plugs therefore play a key role in supporting smooth engine starts, especially in cold conditions. This is why Niterra is constantly expanding its expertise.

Many vehicle manufacturers rely on NGK glow plug technology to meet their quality and performance requirements.

Safe start-up from low ambient temperatures
Supports low emissions during the warm-up phase
Stable idling running before engine reaches operating temperature
High-quality coating on shell for high resistance to corrosion
Unique shell design for excellent heat transfer, effective gas-tight sealing, high shear torque, and high resistance to deformation and security of the heating coils

Reliable cold starts
Fast engine start-up
Long service life

Glow plugs need to perform well under extremely harsh conditions

The conditions required for self-ignition must also be achieved during cold starts and in freezing temperatures. This is why additional heat must be introduced to the combustion chamber. NGK glow plugs are designed to reliably support the pre-glowing process. In that sense, the glow plug functions like an immersion heater. It is introducing electrical energy and heating it up to extremely high temperatures of up to 1350°C.
