ABSTRACT:
A glow plug current supply control system for a diesel engine comprises a rapid heating circuit and an after glow circuit. A current can be supplied to a glow plug through either the rapid heating circuit or after glow circuit. When the after glow circuit is closed, the current is intermittently supplied to the glow plug through thyristor on-off operated by a signal from an oscillator circuit. Before the diesel engine starts, the current is supplied to the glow plug through the rapid heating circuit and after the diesel engine starts, the current is supplied to the glow plug through the after glow circuit.
