2013 Mercedes-Benz S350 Ignition and Tune-Up Products

The new ceramic high-temperature glow plug (NHTC glow plug, New High Temperature Ceramic) has a fully ceramic heating element. It reaches an operating temperature of 1000C in two seconds and can afterglow for up to ten minutes at temperatures up to 1350C. That means: It glows in push phases or during the regeneration phase of the particle filter and thereby minimizes the particle emissions during this time. The NHTC ceramic glow plug was specially developed by NGK to enable automobile manufacturers to comply with the Euro 4 and Euro 5 emissions standards. One of the goals of these standards is to reduce the compression ratio in diesel engines. NHTC glow plugs reach a temperature of 1,000C in less than two seconds and can after-glow for more than ten minutes at temperatures of up to 1,350C. Optimal combustion is assured even with low compression ratios. In addition, the NHTC glow plug can glow intermediately to prevent cooling of the particle filter in deceleration phases. Ceramic glow plugs from NGK guarantee a long service life and ensure a reliable and fast ignition, even at the lowest outside temperatures. At the same time, they reduce harmful emissions.

NGK manufactures all types of glow plugs featuring the latest in technology Worldwide restrictions on automotive exhaust gas emission and the promotion of low pollution vehicles are a reflection of our awareness of the need to protect our environment. Not surprisingly, manufacturers of diesel-powered vehicles are hard at work developing new technology designed to meet increasing restriction on exhaust emissions. Although glow plugs were originally developed as a method for improving the starting performance of diesel engines, technology has developed to the point where glow plugs also contribute to the reduction of exhaust gas emissions.
