CharacteristicsGBCharacteristics of DENSO Glow PlugsTerminal & ShellThe outer casing and terminal are zinc coated to resist corrosion.InsulatorThe Glow Plug insulating disc has exceptional strength, insulation andthermal conductivity to ensure that a short circuit cannot occur.CasingAn alloy casing surrounds and protects the Glow Plug to provide heatresistance.SealA rubber seal is in place to prevent air from seeping through andcorroding the coilInsulationElectrical insulation of the coil is provided by firmly packed magnesiumoxide powder, which is also an efficient heat conductorRegulating CoilThe main coil acts as a regulator within the Glow Plug to control andsustain temperature rise, and ensure a rapid warm-up.Coil ConnectionLaser welding connects the Heating and Regulating coils to maintaintheir position at all times and ensure consistent resistance characteristics.Heating CoilA shorter, tapered coil inside the end of the Glow Plug delivers a quickstart (from as little as 3 seconds) even in cold conditions. It can thenhold its post-heating temperature for up to six minutes after cold start.This contributes to lower engine emissions.TipThe narrowed plug tip ensures improved heating efficiency andexcellent performance.10 DENSO EUROPE BV
