A cover for a cylinder head of an internal combustion engine having a connecting element for attachment the cylinder head and a sealing element arranged between the cylinder head cover and the cylinder head. The connecting element is associated with a connecting area, and the sealing element is associated with a sealing area. The connecting area and the sealing area are constructed independently of each other and are spatially separated from each other, and the force vectors of the connecting force transmitted by the connecting element and the sealing force transmitted by the sealing element form an angle with each other.

An intake manifold (10) for a multi-cylinder internal combustion engine includes a tubular intake distributor (12) from which a plurality of long intake tubes (13) extend and lead to the individual cylinders. Short intake tubes (14) likewise extend from the intake distributor and open into the respective associated long intake tubes (13). The intake distributor (12) and the long and short intake tubes (13, 14) are formed from a one-piece housing (11) which has a cavity (21) which intersects the short intake tubes (14). In this cavity (21) a control element (15) is installed, which includes flaps (16), flap frames (17), a shaft (19) and a control element frame (18). By moving the shaft (19) either rotationally or translationally, the short intake tubes (14) can be opened or closed. In contrast to arrangements known in the prior art, the control element (15) has no sealing elements which can catch or jam during assembly. Additionally, the arrangement of the flaps (16) on a continuous shaft (19) provides a space-saving apparatus.

The invention relates to a venting device (1) for an electrochemical battery (90). The venting device comprises at least one inlet opening (2) for receiving gases venting from the battery (90), at least one outlet opening (3) for venting the gases received from the battery (90), and at least one flame arrester element (4). The inlet opening (2) is in communication with the outlet opening (3) via the flame arrester element (4). An explosion chamber (5, 6) is located within the venting device (1) on the side of the flame arrester element (4) which is directed to the outlet opening (3). The explosion chamber (5, 6) is arranged for developing and temporarily storing an explosive mixture of the gases received from the battery (90) and oxygen from the ambient air, which explodes in case a flame occurs within the explosion chamber (5, 6), thereby blowing off the flame.

An intake device for supplying combustion air to an internal combustion engine composed of two sealingly connected half shells (10, 11) which form an intake air plenum (13), intake ducts (14), and a cylinder head flange (15) in which there is an insert (20) associated with each intake duct (14). Each insert is provided with a partition (23) for dividing the flow into two flow cross-sections (21, 22). The first flow cross section (21) is provided with a valve flap (24), which can be opened and closed to influence the filling of combustion chambers of the internal combustion engine.

The invention relates to a battery cell connector with a first and a second substantially flat limb (1, 2), wherein the first limb (1) has a connecting side (3) for connection to a plurality of electrodes of a battery, the second limb (2) is arranged at an angle with respect to the first limb (1) and extends from that side (4) of the first limb which is opposite the connection side (3), wherein a shoulder (5) is provided which extends from the first to the second limb. Against this background, the invention specifies a battery cell connector with a high current-carrying capacity which is improved in comparison with the known battery cell connectors. For this purpose, the invention provides that the profile of the height (h) of the shoulder (5) from the first limb (1) towards the second limb is nonlinear and is convex with respect to the first and the second limb (1, 2).

摘要:
A method for determining at least one characteristic variable for the state of a battery includes: (a) determining the charge throughput of the battery per time step; having, (b) determining a first characteristic figure in order to describe the stratification of the electrolyte concentration in the battery on the basis of a defined initial state for an as-new battery, and of a second characteristic figure in order to describe the stratification of the state of charge in the battery on the basis of a defined initial value for an as-new battery during operation of the battery, in which (c) in each time step, the first characteristic figure and the second characteristic figure are adapted as a function of the charge throughput from the instantaneous state of the battery, and at least one characteristic variable is determined from the first and the second characteristic figure.
摘要:
A method for determining the amount of charge which can be drawn from a storage battery and a monitoring device are provided that measure at least one of battery currents and battery voltages at at least two points in time before or during a rise phase and during or after a decay phase of a charging or discharging operation. A characteristic variable for the amount of charge is determined. The characteristic variable is derived from the relationship of at least one battery voltage value from the rise phase with respect to at least one battery voltage value from the decay phase or from the relationship of at least one battery current value from the rise phase with respect to at least one battery current value from the decay phase.
摘要:
A method for determining a characteristic variable which relates to the state of charge (SOC) of a storage battery includes determining a first state of charge value which relates to a first parameter for a first operating time and for a second operating time and determining a second state of charge value which relates to a second parameter for the first operating time and for the second operating time. The method also includes determining a first state of charge change of the first state of charge value from the first operating time to the second operating time and determining a second state of charge change of the second state of charge value from the first operating time to the second operating time. The method also includes determining a characteristic variable which relates to the state of charge as a function of the first state of charge change and of the second state of charge change.
