摘要： The fuel supply apparatus for supplying fuel to an internal combustion engine has a fuel tank (2), a first fuel pump (6) that supplies fuel from the fuel tank to a fuel line (10), a second fuel pump (12) that supplies fuel from the fuel line (10) via a pressurized line to at least one fuel valve (16) and a fuel return line (22) that connects the fuel line (10) to the fuel tank for return of excess fuel. A shut off valve (30), which is closed at high temperatures, and a pressure regulator valve (26) are arranged hydraulically in series in the fuel return line (22). A fuel scavenger line (60) is provided, by which fuel at high temperatures is returned to the fuel tank (2). The fuel scavenger line (60) conducts the fuel back to the fuel tank (2), at least partially through the second fuel pump (12) and through a hydraulic resistance. Gas bubble formation is prevented by a high fuel supply pressure and by transfer of heat from the second fuel pump (12).

摘要： A fuel system serves to supply fuel to an internal combustion engine includes a reservoir and a first fuel pump whose input is connected to the reservoir and a second fuel pump whose input is connected to the first fuel pump. At least one injection valve is connected to the second fuel pump and can supply fuel at least indirectly to a combustion chamber. A leakage line is provided between the second fuel pump and the reservoir. In order to permit a reliable hot start of the engine with a simultaneously low strain on the components, the leakage line is provided with a valve device which has a shutoff function and a pressure relief function that are connected in parallel with each other.

摘要： An injection system for internal combustion engines is proposed, in which once the engine has been turned off, a pressure equalization is established between the intake side and the pressure side of the high-pressure fuel pump. This prevents uncombusted fuel from reaching the combustion chambers of the engine. The pressure prevailing on the pressure side and the intake side when the engine is off furthermore assures that vapor bubbles cannot form, and this makes starting the engine easier.

摘要： The aim of the invention is to optimize the running smoothness of an internal combustion engine. To achieve this aim, the individual cylinders are synchronized with respect to their torque contribution. According to the method, fuel is injected into the combustion chamber of a cylinder in at least one injection step, the at least one injection contributing to the torque of the internal combustion engine. Fuel is injected into the combustion chamber of the cylinder in a torque neutral manner by way of a secondary injection during a working stroke of the cylinder and the amount of fuel of the secondary injection us calculated in such a manner that the exhaust gas substantially corresponds to a stoichiometric air/fuel mixture.

摘要： An internal combustion engine is operated according to a method, in which the fuel is pumped from a first fuel pump to a second fuel pump and from there into a high-pressure region. The fuel passes therefrom into at least one combustion chamber of the internal combustion engine, by means of at least one fuel injection device. In certain operating conditions of the internal combustion engine, the pressure in the high-pressure region is lowered by means of a release device. According to the invention, the reliability and security of operating the internal combustion engine may be increased by monitoring the functioning of the release device (58 through 68).
