BERU Glow Plug - GE133

      QUICK START IN 2 SECONDS
With the post-heating BorgWarner GN glow plug, it is possible to reduce the glow
time to 2–5 seconds. To achieve this, the designers reduced the diameter at the front
end of the heating rod. The heating rod thus starts glowing quicker in this zone. At a
temperature of 0 °C, this takes just 2 seconds until start. When temperatures are
lower, the system is accordingly adapted to the requirements by the glow-time
control, and glow time will respectively increase: at –5 °C approx. 5 and at –10 °C
approx. 7 seconds.
REDUCTION OF WHITE/BLUE SMOKE
So-called white or blue smoke is emitted from the exhaust until the ideal ignition
temperature has been reached. These types of smoke produced are the result of
incomplete combustion of the fuel, resulting from too low an ignition temperature.
Post-heating causes the diesel fuel to burn more completely and with less noise
during the warm-up phase. Smoke opacity is thus reduced by up to 40%.
ELIMINATION OF COLD-START KNOCKING
Knocking during cold-start of a diesel engine is caused by an increased ignition
delay when the engine is cold. The fuel ignites abruptly, and the engine knocks.
Pre-heating and post-heating of GN glow plugs ensure that the engine reaches the
operating temperature quicker. This preserves the engine, results in quieter engine
running and prevents knocking. The fuel will then be burnt more evenly and more
completely. More energy is thus released and the combustion chamber temperature
will increase faster.
