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.

An air-compressing four-cycle reciprocating internal combustion engine to which is flangedly connected transmission housing means by way of clutch housing means which house, respectively, transmission means and clutCh means. the connections between at least two of the parts consisting of the internal combustion engine, the clutch housing means and the transmission housing means are provided with such reinforcement means as to define an oscillatory system having the masses of the internal combustion engine, at least one of the clutch housing means and the transmission housing means, wherein the natural frequencies of said oscillatory system are higher than the frequencies of the oscillations which are excited by the moment of the second order, caused by the oscillating masses of the internal combustion engine, the transmission housing means being substantially box-shaped and including upper wall means inclined with respect to the longitudinal axis of the transmission housing means at least over half the length thereof, rising in the direction toward the clutch housing means, said clutch housing means including upper wall means adjoining the upper wall means of the transmission housing means so that the separating surfaces between the clutch housing means and transmission housing means are extended in the upward direction beyond the space requirements of the clutch and of the transmission means housed within said housing means, and the upper wall means is inclined and subtends with the longitudinal axis thereof at least approximately the same angle of inclination as the upper wall means of the transmission housing means, wherein the angle of inclination which the upper wall means of the transmission housing means subtends with the longitudinal axis, amount to about 20°.
