Abstract

A motor vehicle with an internal combustion engine which is installed into a motor chamber in the longitudinal direction and which has a multi-joint crank drive with an eccentric shaft and a crankshaft starter is disclosed. The crankshaft starter is arranged relative to the internal combustion engine such that a longitudinal central cylinder plane, which is spanned by longitudinal central cylinder axes of the internal combustion engine, lies between the crankshaft starter and the eccentric shaft.

First claim

What is claimed is:

1 .- 10 . (canceled)

11 . A motor vehicle, comprising:
an internal combustion engine mounted in longitudinal direction in a motor space of the motor vehicle, said internal combustion engine comprising a multi-joint crank drive with an eccentric shaft; a crankshaft starter arranged relative to the internal combustion engine so that a cylinder longitudinal center plane spanned by cylinder longitudinal center axes of the internal combustion engine is situated between the crankshaft starter and the eccentric shaft; a belt starter arranged on a same side of the cylinder longitudinal center plane as the eccentric shaft, wherein the crankshaft starter and the belt starter are arranged above a parallel plane which extends parallel to a bottom delimiting plane of the internal combustion engine and includes a rotation axis of the eccentric shaft and the belt or which extends parallel to the bottom delimiting plane and tangentially contacts an effective enveloping surface of a crankshaft of the internal combustion engine; and an actuator for adjusting the eccentric shaft, said actuator being situated below the parallel plane and on the same side of the cylinder longitudinal center plane as the eccentric shaft.

12 . The motor vehicle of claim 11 , wherein the crankshaft starter is configured as a pinion starter.

13 . The motor vehicle of claim 11 , further comprising a transmission operatively connecting the actuator and the eccentric shaft, said transmission being arranged when viewed in longitudinal direction of the internal combustion engine on a side of the internal combustion engine which faces away from an output of the crankshaft.

14 . The motor vehicle of claim 11 , further comprising a motor support, wherein the crankshaft starter is arranged in a hollow space formed between the internal combustion engine and the motor support, and wherein the internal combustion engine is fastened to a body of the motor vehicle via the motor support.

15 . A method for assembling a motor vehicle, said method comprising:
mounting an internal combustion engine in the motor vehicle in longitudinal direction in a motor space of the motor vehicle, said internal combustion engine comprising a multi-joint crank drive with an eccentric shaft, wherein the internal combustion engine is mounted in the vehicle so that a crankshaft starter is arranged relative to the internal combustion engine so that a cylinder longitudinal center plane spanned by cylinder longitudinal center axes of the internal combustion engine is situated between the crankshaft starter and the eccentric shaft, a belt starter is arranged on a same side of the cylinder longitudinal center plane as the eccentric shaft, wherein the crankshaft starter and the belt starter are arranged above a parallel plane which extends parallel to a bottom delimiting plane of the internal combustion engine and includes a rotation axis of the eccentric shaft and the belt or which extends parallel to the bottom delimiting plane and tangentially contacts an effective enveloping surface of a crankshaft of the internal combustion engine; and an actuator for adjusting the eccentric shaft is situated below the parallel plane and on the same side of the cylinder longitudinal center plane as the eccentric shaft.

16 . The method of claim 15 , further comprising arranging the crankshaft starter of the internal combustion engine on the internal combustion engine and electrically connecting the crankshaft starter to the internal combustion engine, and subsequently fastening an exhaust gas system on the internal combustion engine.
