摘要:
An injection device for an internal combustion engine having a first injection system for injecting fuel having a first fuel composition, and a second injection system for the injection of fuel having a second fuel composition that has a lower ethanol component than the first fuel composition, the first injection system having at least one first fuel injector for injecting fuel having the first fuel composition both in the direction of a first intake orifice of a combustion chamber of the internal combustion engine, and in the direction of a second intake orifice of the combustion chamber, wherein the second injection system has a second fuel injector for injecting fuel having the second fuel composition essentially only in the direction of the first intake orifice, and a separate third fuel injector for injecting fuel having the second fuel composition essentially only in the direction of the second intake orifice.
摘要:
The invention relates to a tank arrangement (2), comprising a fuel tank (4) comprising at least one fuel chamber (6, 6a, b), a tank installation unit (8) arranged in the fuel tank (4), a fuel pump element (10) arranged in the installation unit (8) and designed to make fuel (12) available from the tank arrangement (2) to a fuel user (14), a pump unit (6, 16a, b) arranged in the fuel chamber (6, 6a, b) and operatively connected to the fuel pump element (10) and designed to convey fuel (12) out of the fuel chamber (6, 6a, b) into the tank installation unit (8), and a pressure regulating element (18), functionally arranged between fuel pump element (10) and pump unit (16). The arrangement is characterised in that the pressure regulating element (18) is designed as a mechanical pressure regulator.
摘要:
A method and a device for supplying fuel into a combustion chamber of a cylinder of an internal combustion engine, in which an air-fuel mixture is supplied to the cylinder via at least two intake sections, which are connected to the cylinder via an intake valve, and each of the intake sections is assigned an injector, fuel being injected into the intake sections in at least intermittently asynchronous manner.
摘要:
A fuel injection system (1) with at least one fuel injector (1a) and a heatable adapter (1b), which is connected to a fuel rail (1c) and to the fuel injector (1a) of the fuel injection system (1); a thermoswitch (2) is provided in the fuel rail (1c), which is connected with an external door contact switch (3) and with the heatable adapter (1b). The thermoswitch (2) includes a thermosensor, so that a reliable cold start is ensured by the fact that, when a previously specified fuel temperature is fallen below, the thermoswitch (2) switches over and causes fuel (8) to be heated.

摘要:
In a method for operating an internal combustion engine of a motor vehicle, a driver type is ascertained. A criterion for performing a diagnosis or a regeneration of a component of the fuel supply system is a function of the ascertained driver type.
摘要:
In a fuel supply system for an internal combustion engine in which a gas delivery pump, a fuel pump and an electric motor are included in the fuel supply system and form a pump unit, the electric motor is incorporated in the system in such a way that it can selectively drive either one or both of the pumps.
摘要:
In a method and a circuit for installation-exchange protection of at least two measuring sensors for detecting physical/chemical variables of an exhaust gas in a system for exhaust-gas aftertreatment in an internal combustion engine, especially of a motor vehicle, voltage signals of the at least two measuring sensors are read in such that the read-in voltage signals are digitized and the digitized voltage values are buffer-stored. The buffer-stored voltage values each are buffer-stored as a copy. The voltage values buffer-stored as a copy are evaluated on the basis of characteristic voltage variables. During the process it is checked whether an exchange of the at least two measuring sensors has occurred and that, as a function of the test result, the buffer-stored voltage values are each buffer-stored as copies in a crosswise manner.
