Abstract: A heavy goods vehicle or omnibus motor vehicle with reduced sound emissions, having a diesel engine, the operation of which can be regulated by an injection pump by an engine electronics unit which includes a microprocessor, a data and program store and input and output peripherals. Measures for at least temporarily reducing the sound emissions by the engine can be carded out to and/or at a level preferably prescribed by legislation, by regulating operation of the engine such that free and/or additional data storage locations that need to be provided in the engine electronics unit switch to a reduced-noise mode, the effect of which at least temporarily increases consumption and at the same time is at least approximately constant in terms of power and rotation speed, and which reduces the emission of sound from the drive and/or engine, in particular the reduced-noise mode lowers the rail pressure, defers the injection to a later time and/or provides a greater volume of subsets in the fuel metering.
