An automatic control system for turbo-charged truck Diesel engines incorporates one or more electronic or electromechanical timers for the operation of the fuel line solenoid valve and of the fast-idle solenoid, where fitted. The timers are automatically started upon the opening of the ignition switch, or are controlled from an independent control switch, in such a manner that upon the receipt of a 'start' signal, the engine continues to operate for predetermined periods in the 'fast idle' and 'idle' speed regimes and is then shut down. These periods of operation at slow speeds permit the exhaust-driven turbocharger to attain equilibrium temperatures before engine shut-down.
