6.33. System of prestarting heating

In each vortex camera of an ustanavla the glow plug is howled. Glow plugs are used at start of the cold engine. Giving of tension to glow plugs is run a timer in combination with diesel an electron by the ny control device – system of injection.

The control lamp in a combination of devices burns during the work of candles of an incandescence. After switching off of a lamp the engine can be started. Tension to glow plugs moves within several seconds after inclusion of a control lamp. If the attempt to start the engine after switching off of a lamp does not become, the timer disconnects tension from incandescence candles to avoid a discharge of the accumulator and an overheat of candles of an incandescence.

The fuel filter is also equipped with an element of heating which is established between the filter and a casing and is operated system of prestarting heating. The element of heating joins if temperature of the fuel passing through the filter is less than 5 °C and is switched off after when temperature of fuel reaches 16 °C.

PERFORMANCE ORDER
1. Connect the voltmeter between the feeding tire of candles of an incandescence and the earth. Include ignition and check that tension to candles moves in a sootvetstvo a yushchy interval of time.
2. At the air temperature of 20 °C time intervals of giving of tension to glow plugs have to make 3 sec. at which the control lamp burns. Time of burning of a control lamp increases at lower temperatures and decreases at temperature increase. If tension moves to glow plugs, the relay and an electrical wiring means are serviceable.
3. Using a tester, check integrity of candles of an incandescence, checking resistance between contact in the top part of a candle and the candle case. Сопротив leny glow plugs it is less than 1 Ohm and if the tester shows bigger resistance, the glow plug is faulty.
