6.4. System of prestarting heating of diesel engines

6.4.1. Introduction


In each vortical chamber the glow plug is established. Glow plugs are used at start of the cold engine. Tension giving to glow plugs copes a timer in a combination to the diesel electronic control device – injection system.

The control lamp in a combination of devices burns at work of candles of an incandescence. After lamp switching off the engine can be started. Tension to glow plugs moves within several seconds after inclusion of a control lamp. If attempt to start the engine after lamp switching off 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.

On models with engines of 1,7 l the fuel filter is also equipped with an element of heating which is established between the filter and a casing and copes system of prestarting heating. The element of heating joins, if the temperature of the fuel passing through the filter less than 5 ° With and is switched off after when the temperature of fuel reaches 16 ° Page.


Connect the voltmeter between feeding tire of candles of an incandescence and the earth. Include ignition and check that tension to candles moves in the corresponding interval of time.

At air temperature 20 ° About time intervals of giving of tension to glow plugs should make 3 seconds 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 electroconducting means are serviceable.

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. Resistance of a glow plug less than 1 Ohm and if the tester shows bigger resistance, the glow plug is faulty.
