6.4. System of prestarting heating of diesel engines

6.4.1. Introduction

In each vortical chamber the candle накаливания is established. Candles накаливания are used at start of the cold engine. Pressure giving to candles накаливания 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 накаливания. After deenergizing of a lamp the engine can be started. Pressure to candles накаливания moves within several seconds after inclusion of a control lamp. If attempt to start the engine after lamp deenergizing does not become, the timer disconnects pressure from candles накаливания to avoid a discharge of the accumulator and an overheat of candles накаливания.

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


Connect the voltmeter between feeding tyre of candles накаливания and the earth. Include ignition and check up that pressure to candles moves in a corresponding interval of time.

At temperature of air 20 About time intervals of giving of pressure to candles накаливания should make 3 seconds at which the control lamp burns. Time of burning of a control lamp increases at lower temperatures and decreases at rise in temperature. If pressure moves to candles накаливания, the relay and electroconducting means are serviceable.

Using a tester, check up integrity of candles накаливания, checking resistance between contact in the top part of a candle and the candle case. Resistance of a candle накаливания is less 1 Ohm and if the tester shows большее resistance, a candle накаливания is faulty.
