Abstract
Spark ignition plugs are used in place of the glow plugs in a Diesel engine. As long as engine preheating contacts remain closed, pulses of a fixed frequency are applied to two transistors arranged in a push-pull configuration and connected to the primary coil of a transformer so that an engine plug connected to the secondary coil of the transformer repeatedly discharges continuously.
