Abstract of the Disclosure An electrical governor system for a turbocharg- ed diesel engine which eliminates objectionable puffs of smoke when gears are shifted, by limiting the rate of fuel delivery to the engine at such times. The response charac- teristics of the turbocharger to changes in kinetic energy of the engine exhaust flow are determined and stored in a microprocessor memory. The engine operating parameters are monitored to produce signals representative of engine speed and fuel delivery rate, and these signals are sup- plied to the microprocessor to cause it to generate a signal representative of the maximum rate at which fuel can then be delivered to the engine without producing objectionable exhause smoke. The latter signal is used to control the fuel-control each automatically, through a stepping motor arrangement, at appropriate times to limit the fuel delivery rate to said maximum and thus avoid objectionable smoke puffs.
