Example Embodiment

[0029]infigure 1 A part of a preferred embodiment of the drive train 1 according to the present invention is schematically depicted in a cross-sectional view. The drive train 1 has an internal combustion engine 3 whose cylinder head 14 with an exhaust manifold 5 is depicted in this figure. In the cylinder head 14, an intake valve 15 for letting fresh air into the cylinder 4 of the internal combustion engine 3 and an exhaust valve 16 for discharging exhaust gas from the cylinder 4 are arranged. A plurality of cooling channels 17 are constructed in the cylinder head 14. Furthermore, an exhaust gas outlet 9 of the burner device 6 which is only partially visible is constructed in the cylinder head 14. The exhaust gas outlet 9 opens into the exhaust duct 7 of the exhaust manifold 5 in the region of the exhaust valve 16 and points toward the exhaust valve 16. The exhaust gas outlet 9 thus points opposite to the flow direction of the exhaust gas leaving the cylinder 4.

Abstract

The invention relates to a drive train (1) for a motor vehicle (2), having an internal combustion engine (3) with a plurality of cylinders (4) and pistons, which are guided in the cylinders (4) in a linear manner, an exhaust manifold (5) for combining the exhaust gases emitted from the cylinders (4) and a combustion apparatus (6) for burning a fuel outside of the cylinders (4) in order to generateheat. The combustion apparatus (6) is coupled to the exhaust manifold (5) in a fluidically communicating manner such that exhaust from the combustion apparatus (6) can be introduced into an exhaust duct (7) of the exhaust manifold (5). The invention further relates to a motor vehicle (2) having a drive train (1) with an internal combustion engine (3).

Description

technical field [0001] The invention relates to a drive train with an internal combustion engine for a motor vehicle. Furthermore, the invention relates to a motor vehicle with a drive train of this type. Background technique [0002] An internal combustion engine designed to combust liquid or gaseous fuels or especially fuel mixtures consisting of fuel and filtered and compressed air in order to be expanded by reactants (reaktionspartner, sometimes referred to as reaction participants) associated therewith acting. Combustion can be initiated, for example, by self-ignition, for example in a diesel engine by compression of the fuel mixture, or by ignition from an external source, for example by means of an ignition spark additionally generated for this purpose. [0003] During the combustion of various fuels or fuel mixtures, exhaust gases such as, for example, carbon monoxide, carbon dioxide, nitrogen oxides, hydrocarbons and soot particles occur as by-products. To comply...
