Glow Plugs are essential components in diesel engines, playing a crucial role in cold starting and reducing emissions. BERU, a leading manufacturer, offers a diverse range of innovative glow plugs, each engineered with specific features for various applications and to meet stringent performance demands.
Pressure Sensor Glow Plugs (PSG)
Pressure Sensor Glow Plugs (PSG) represent a significant advancement in glow plug technology. These sophisticated plugs are equipped with an integrated sensor and miniaturized electronics within the pin. This innovative design allows for real-time monitoring of the combustion chamber pressure. The sensor data is relayed to the engine control unit, enabling precise adjustments to the glow plug’s heating pattern. This optimization is crucial for minimizing particle emissions, ensuring diesel engines not only meet but exceed current exhaust gas regulations. Key features of the PSG include:
- Sensor Principle: Utilizes piezoresistive technology for accurate pressure measurement.
- Flexible Heating Rod: Facilitates efficient pressure transmission from the combustion chamber to the sensor.
- Robust Sealing Element: Ensures a durable seal between the body and heating rod, withstanding harsh engine conditions.
- Integrated Miniaturized Electronics: Compact electronics are housed within the upper part of the glow plug for efficient signal processing.
- Calibrated and Customer-Specific Program: Each PSG is calibrated and programmed to meet specific customer and engine requirements.
- Integrated Concentric Automotive Plug: Ensures reliable electrical connection within automotive systems.
- Operating Temperature Range: Designed to operate reliably from -40°C to 140°C, withstanding peak temperatures up to 150°C.
- Pressure Range: Accurately measures pressure within a range of 0-200 bar, withstanding maximum pressures up to 210 bar.
Ceramic Glow Plugs (CGP)
Ceramic Glow Plugs (CGP) represent the cutting edge in glow plug technology, leveraging BERU’s expertise in high-temperature materials. BERU was a pioneer in bringing CGP technology to market for major automotive brands. These extreme temperature glow plugs are engineered to reach a maximum temperature of 1300°C in under 3 seconds. This rapid heating capability translates to enhanced engine stability, optimized combustion performance, and improved fuel efficiency, particularly during cold starts. The extreme heat generated by CGPs ensures reliable ignition even in the most challenging cold weather conditions.
High-Tech Steel Glow Plugs
BERU high-tech steel glow plugs provide a robust, fast-heating, and environmentally conscious solution for both two-phase and three-phase glow technologies commonly found in diesel engines. These steel glow plugs are differentiated primarily by their heating phase technology:
Three-Phase Technology Glow Plugs (Types GE & GN)
These advanced glow plugs utilize a three-phase heating process to maximize combustion efficiency and minimize emissions. The three phases are:
- Pre-heating: Warms the combustion chamber before ignition to facilitate easier starting.
- Heating During Starting: Provides continuous heat during the engine starting phase to ensure reliable ignition.
- Post-heating: Continues to heat for approximately 3 minutes after the engine starts. This post-heating phase ensures more complete combustion of diesel fuel, resulting in quieter engine operation and a significant reduction (up to 40%) in exhaust gas clouding, especially during cold starts. Three-phase glow plugs like Types GE & GN guarantee dependable starts, even in extremely cold climates down to -30°C.
Two-Phase Technology Glow Plugs (Type GV)
Two-phase technology glow plugs, such as Type GV, are designed to meet the pre-heating and heating demands of older diesel engine models. These plugs provide reliable cold starting performance with a short pre-heating time typically ranging from 5 to 7 seconds. They offer a dependable and efficient solution for older diesel systems requiring effective cold start assistance.
Commercial Vehicles Glow Plugs
BERU extends its glow plug expertise to the commercial vehicle sector, offering a specialized range of glow plugs tailored to the rigorous demands of vans, trucks, and industrial applications. This range includes:
Flame Start System (Type GF)
The Flame Start System (Type GF) delivers dependable, convenient, and environmentally friendly cold starting for commercial vehicles, even in very low temperatures. Available in both 12V and 24V versions, the Flame Start System is characterized by a rapid pre-heating time and an extended post-flame time. This system ensures quick and reliable starts while minimizing emissions, crucial for commercial operations in diverse climates.
Glow Plugs for Auxiliary Heaters (Type GH)
Glow plugs designed for auxiliary heaters (Type GH) provide supplemental warmth and cabin comfort in vehicles, particularly in cold conditions. Available in various versions to suit auxiliary heaters in both gasoline and diesel vehicles, these glow plugs ensure efficient and reliable operation of auxiliary heating systems, enhancing driver and passenger comfort in harsh weather.
Glow Plugs with Wire Filaments as Heater Element (Type GD)
Glow plugs featuring wire filaments as the heating element (Type GD) are robust and reliable solutions for older diesel vehicles, including tractors, tow trucks, and construction machinery. These heavy-duty glow plugs are specifically engineered to withstand significant vibrations and harsh operating conditions common in these applications. The wire filament design offers durability and dependable performance for older diesel systems.
In conclusion, BERU’s comprehensive range of glow plugs demonstrates a commitment to innovation and quality, providing tailored solutions for a wide array of diesel engine applications, from passenger cars to heavy-duty commercial vehicles. Each type of glow plug is designed to optimize engine performance, improve fuel efficiency, and reduce emissions, meeting the evolving needs of the automotive industry and environmental standards.
