Abstract
An electrical governor system for a turbocharged 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 characteristics 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 supplied 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 exhaust 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.
