摘要:
A parallel circuit of an ordinary resistor exhibiting an ordinary resistance characteristic and a starting resistor abruptly increasing its resistance at a certain temperature is inserted between glow plugs in a Diesel engine and a battery. The resistance of the starting resistor is smaller than that of the ordinary resistor at a normal temperature. The resistance of the starting resistor becomes larger than that of the ordinary resistor when a large amount of current flows through the starting resistor. Therefore, current flows from the battery to the glow plugs mainly through the starting resistor at first, and then it flows mainly through the ordinary resistor. The ordinary resistor is disposed in an intake air passage of the engine.
