1. An injection device for an internal combustion engine, comprising: at least one injection valve system for injecting fuel into an intake manifold of the internal combustion engine and including a first injection valve, a second injection valve, and a third injection valve;a central fuel supply line supplying fuel at least to the first, second, and the third injection valves; andonly one heating device situated in the central fuel supply line for pre-heating the fuel before the fuel is injected, the single heating device being common to and supplying heat to all injection valves connected to the central fuel supply line; wherein the first injection valve injects the fuel in the direction of a first inlet opening of a first cylinder of a combustion chamber of the internal combustion engine, the second injection valve injects the fuel in the direction of a second inlet opening of the first cylinder, and the third injection valve injects fuel in the direction of a first inlet opening of a second cylinder,wherein the at least one injection valve system includes a fourth injection valve for injecting the fuel in the direction of the first inlet opening of the first cylinder,wherein the first injection valve and the fourth injection valve are controllable independently of one another such that different quantities of fuel may be injected by the first and the fourth injection valves; anda central further fuel supply line supplying fuel at least to the fourth injection valve, wherein a further heating device is situated in the central further fuel supply line for pre-heating fuel before the fuel is injected. 2. An injection device for an internal combustion engine, comprising: at least one injection valve system for injecting fuel into an intake manifold of the internal combustion engine and including a first injection valve, a second injection valve, and a third injection valve;a central fuel supply line supplying fuel at least to the first, second, and the third injection valves; andonly one heating device situated in the central fuel supply line for pre-heating the fuel before the fuel is injected, the single heating device being common to and supplying heat to all injection valves connected to the central fuel supply line; wherein the first injection valve injects the fuel in the direction of a first inlet opening of a first cylinder of a combustion chamber of the internal combustion engine, the second injection valve injects the fuel in the direction of a second inlet opening of the first cylinder, and the third injection valve injects fuel in the direction of a first inlet opening of a second cylinder,wherein the at least one injection valve system includes a fourth injection valve for injecting the fuel in the direction of the first inlet opening of the first cylinder,wherein the first injection valve and the fourth injection valve are controllable independently of one another such that different quantities of fuel may be injected by the first and the fourth injection valves,wherein the at least one injection valve system includes a fifth injection valve for injecting fuel in the direction of the second inlet opening of the first cylinder, andwherein the second and the fifth injection valves are controllable independently of one another, and the second injection valve and the fifth injection valve are dimensioned differently from one another such that different quantities of fuel may be injected by the second injection valve and the fifth injection valve. 3. An internal combustion engine, comprising: an injection device including:at least one injection valve system for injecting fuel into an intake manifold of the internal combustion engine and including a first injection valve, a second injection valve, and a third injection valve;a central fuel supply line supplying fuel at least to the first, second, and the third injection valves; andonly one heating device situated in the central fuel supply line e for pre-heating the fuel before the fuel is injected, the single heating device being common to and supplying heat to all injection valves connected to the central fuel supply line; wherein the first injection valve injects the fuel in the direction of a first inlet opening of a first cylinder of a combustion chamber of the internal combustion engine, the second injection valve injects the fuel in the direction of a second inlet opening of the first cylinder, and the third injection valve injects fuel in the direction of a first inlet opening of a second cylinder,wherein the at least one injection valve system includes a fourth injection valve for injecting the fuel in the direction of the first inlet opening of the first cylinder,wherein the first injection valve and the fourth injection valve are controllable independently of one another such that different quantities of fuel may be injected by the first and the fourth injection valves; anda central further fuel supply line supplying fuel at least to the fourth injection valve, wherein a further heating device is situated in the central further fuel supply line for pre-heating fuel before the fuel is injected. 4. The injection device of claim 1, wherein the first injection valve and the fourth injection valve are dimensioned differently from one another such that different quantities of fuel may be injected by the first and fourth injection valves.
