2009 Mercedes-Benz E320 Glow Plugs

The Dependable Glow Plug for Diesel Engines of Older Generations (Type GV) In older generations of vehicles, the glow plug is only used for pre-heating and heating during starting (2-phase heating); once the engine has started, the glow plug is switched off. BERU 2-coil sheathed glow plug: reliable cold starting in only 5-7 seconds.

Product Features:

• Sheathed glow plug in 2-coil technology
• Reliable cold starting
• Short pre-heating time (5-7 seconds depending on vehicle!)

NGK’s patented NHTC (New High Temperature Ceramic) glow plugs were developed for OEM diesel engine manufacturers to comply with ever-stricter emissions standards. Compared to metal glow plugs, NHTC glow plugs have a more robust, fully ceramic heating element which is encased in a ceramic insulator. NGK NHTC glow plugs reach operating temp of 1,000 degrees C in less than 2 seconds and can after-glow for more than 10 minutes at temps of up to 1,350 degrees C. Silicon nitrate ceramic material, combined with optimized shape and joining process provide superior thermal shock and vibration resistance, ensuring stable engine starts. Fine ceramic heater provides durability in high-temperature conditions, improves combustion and reduces emissions.

Product Features:

• ACTUAL OE or EQUIVALENT DESIGN: OEM quality construction ceramic glow plug
• PATENTED TECHNOLOGY: Exclusive NHTC New Ceramic High Temperature design
• NEAR-INSTANT HEATING: Fully ceramic heating element reaches operating temperature in less than two seconds
• CLEAN PERFORMANCE: Constant afterglow temperature minimize noxious pollutants
• RECOMMENDED USAGE: Best for diesel engines with OE ceramic glow plugs

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.

High-tech glow plugs, pre-start and post-glowing (type GE, type GN) Diesel starting is now quicker, more reliable and more environmentally friendly. BERU is one of the leading manufacturers of glow plugs in the world – and inventor of numerous innovations in Diesel cold start technology The latest diesel car engines are equipped with the innovative three-phase glow technology (pre-heating – heating during starting – post-heating). This means: the glow plug not only heats prior to and during the starting phase, but also up to 180 seconds after starting. This protects the environment and the engine. BERU offers 3-phase glow plugs of the GE and GN type. GE and GN glow plugs in 2-coil technology have not only a heating coil to maintain the optimal heating temperature, but also have a regulator coil that effectively protects the glow plug from overheating. In this way BERU glow plugs are extremely reliable and durable. The GE glow plug is a performance-optimized, controlled glow plug used in engines of the latest generations. The fast heating of the glow plug and the controlled operation are provided by a programmable micro-controller in the glow time control unit.

Product Features:

• Super quick start glow plugs in new, slim shape
• Extremely short pre-heating time: from 2 seconds
• Reliable starting (even at -30C)
• Can be used for post-heating, as a result environmentally friendly: up to 40% less pollutant emissions during the warm up phase
• No more cold start knocking
• Quieter engine running
• Protects the engine during starting

NGK metal glow plugs are trusted by OEM diesel engine manufacturers around the world to perform under the harshest conditions. NGK metal glow plugs are equipped with a heating coil in a glow rod made of heat-resistant magnesium oxide between the heating and regulating coils. Magnesium oxide is an outstanding thermal conductor (quickly dissipating heat), while protecting the heating coils from vibration and shock. NGK metal glow plugs feature excellent gas-tight sealing qualities that deliver superior electrical insulation and protection against combustion gas. NGKs metal composition helps reduce carbon accumulation to prevent short circuits, while the unique shell design provides excellent heat transfer.

Product Features:

• ACTUAL OE or EQUIVALENT DESIGN: OEM quality construction metal glow plug
• SUPERIOR DURABILITY: Metal glow plugs are designed to withstand thermal shock due to quick changes in temperature
• FAST HEATING PERFORMANCE: Fast heat up enables smooth engine starts even in extreme weather conditions
• CLEAN PERFORMANCE: Constant afterglow temperature minimize noxious pollutants
• RECOMMENDED USAGE: Best for diesel engines with OE metal glow plugs
