The device is pre-heating the diesel engine
The device consists of a preheating relay control heating glow plugs, 4/5-rod glow plugs and heating control light on the dashboard. In a cold engine only enough compression to ignite the fuel, so the engine needs to be warmed up. The duration of heating depends on the ambient temperature and is controlled by a switch control heating. When a fault or a glow wire current-carrying supply relays heating device is switched off lamps. Glow plugs Voltage provided by the parallel circuit. If the ignition key is in position without starting the engine warm-up, the safety circuit relays heating after 20-25 seconds, disconnect the plug. To restart heating ignition key must first be installed on the 0-position. When you turn on the device through each filament glow plug current flows about 30 A. Due to the regulating winding current consumption candle temperature increases limited to 8-15 A. The glow plug is protected against overload. Rod glow plug consists mainly of a housing with an embedded heating element. Heating element in turn connected in series consists of heating and regulating winding. When voltage heating coil heats up. After nine seconds of filament heating rod temperature is 900 ?� C, and after 30 seconds, the maximum temperature reached 1180 ?� C. To improve the characteristics of the warm engine at idle, further warming the engine running is dependent on the coolant temperature. The re-heating of the engine capacity of 2.0 liters is a maximum of 17 seconds. On engines in volume of 2,2 / 2,5 l re warming up to 3 minutes; failure coolant temperature sensor associated with re-warming, the duration of the last 30 seconds. Maximum plugs warming up the engine capacity of 2.2 / 2.5 L
COOLANT TEMPERATURE | MAXIMUM TIME prestarting warming | -30 ?� C | 16 sec. | -20 ?� C | 12 sec. | -10 ?� C | 7 sec. | 0 ?� C and + 30 ?� C | 6-4 seconds. |
