About NGK Glow Plugs

NGK are the world's Number1 spark plug manufacturer so you wouldn't expect anything less from their glow plugs. NGK have been developing engine pre-heating glow plug technology since the early 1960s. Inbuilt advanced technology ensures that automotive manufacturers and their engineering design teams can extract the best performance and efficiency from their engines, helping them meet the ever increasing emission targets which are necessary to improve our environment now and for the future.
Diesel engines use self igniting technology, heat generated by compression ignites the fuel as it is injected under high pressure. In theory a diesel engine can be started and run without any additional source of ignition. In reality it is far more efficient to include pre glow technology, an electrically heated element within the combustion chamber to encourage ignition whilst engine temperatures are low during warm up and idling. The tip of a glow plug will continue to glow and be a source of heat and ignition even after electrical power has been disconnected to the heating element. Modern engines employ computer control units to cycle power to the glow plugs as required to maintain engine efficiency and reduce emissions.
