Abstract

An air-compressing four-cycle reciprocating piston injection internal combustion engine forming a driving engine of a motor vehicle, to which is flangedly connected a transmission by way of a clutch; the connections between the internal combustion engine and the clutch and/or between the clutch and the transmission are provided with such reinforcements that the natural frequencies of the oscillatory system, which includes the masses of the internal combustion engine, of the clutch and of the transmission, are higher than the frequencies of the dangerous exciting oscillations caused by the internal combustion engine constructed as five-cylinder in-line internal combustion engine which cannot be compensated for with the use of acceptable expenditures.
