Abstract
In an auxiliary starter apparatus for four-cylinder diesel engine, each cylinder of which has a 12-volt glow plug adapted to be operated by a voltage of 12 volt, each of the four glow plugs has an electrical resistor. There is provided a first state in which each of the two electrical resistors connected in series is connected in parallel to form an electrically conductive path. A second state is provided in which the four electrical resistors are each connected in series to form an electrically conductive path. Electromagnetic relays are placed to alternatively select the first and second state. A 24-volt battery cell is provided, a voltage of which is impressed across the electrically conductive path of the first state by the first and second electromagnetic relay when starting the diesel engine, while the voltage of the 24-volt battery cell impressed across the electrically conductive path of the second state by the first and second electromagnetic relay once the diesel engine has started.
