摘要:
A device and a method for controlling an internal combustion engine. At least one first partial injection and one second partial injection are provided per injection cycle. One of the two partial injections is shifted in response to certain operating conditions being active. A correction value for a variable characterizing the delivery period is determined as a function of the shift of the partial injection.
摘要:
A process and a device for controlling an internal combustion engine in which a control unit is temporarily connected to an external tester via an interface. At least one storage device of the control unit is configured as first and second storage elements. The first storage element is supplied with data corresponding to a signal transmitted from the tester. The second storage element is supplied with data from the control unit. Either the contents of the first storage element or the contents of the second storage element are selected, with the contents of the second storage element being selected when the contents of the first storage element have an unallowable value.
摘要:
A piezoelectric actuator and an injector for an internal combustion engine are proposed, the electromagnetic compatibility of which is significantly improved in comparison with conventional injectors. The actuator head and/or actuator foot is manufactured out of a ceramic material, thus reducing the capacitance of the electric capacitor that is formed between the electrical ground and the piezoelectric actuator. An advantage of the piezoelectric actuator according to the invention is that no additional components are required. The change from metallic materials to ceramic materials also increases the rigidity of the piezoelectric actuator since ceramic materials have a significantly higher modulus of elasticity than metals.
摘要:
A system is described for the control of an internal combustion engine, in particular a diesel gasoline engine, in the case of which at least one solenoid valve determines the beginning and the end of the fuel metering. First device (130) evaluate the signals of at least one first sensor (110) which generates a plurality of increment pulses. Second device (140) evaluate the signals of at least one second sensor. The second device transmits an angle size to the first device at specifiable points of time. The first device releases a signal starting out from this angle size and the signals of the first sensor (110).
