摘要： The invention relates to a connection (24) between a stem end (20) on a gas exchange valve (1) in an internal combustion engine and a sleeve-like actuator body (2) of a valve actuator (4), which may be axially displaced within a pressure region (58) pressurised with a pressure agent in the valve actuator (4) and which at least partially encloses the stem end (20). According to the invention, the connection is formed outside the pressure region (58) and arranged in the region of an opening (16) which is preferably coaxial with the stem end (20) and formed on the side of the valve actuator (4) away from the combustion chamber.

摘要： The invention relates to a connection between two shaft ends (8, 10), positioned coaxially one behind the other, of a gas shuttle valve (1) in an internal combustion engine, and a piston rod (2) of a valve actuator (4), by means of at least one coupling body (14), which at least partially surrounds the shaft ends (8, 10). The aim of the invention is to create static frictional contact between each of the shaft ends (8, 10) and the coupling body (14), said contact transmitting the actuating displacement of the valve actuator (4) to the gas shuttle valve (1) without slippage. To achieve this, said coupling body is tensioned radially against the two shaft ends (8, 10), by the action of at least one tensioning body (34, 36). This both increases the durability of the connection and simplifies its assembly and disassembly.

摘要： The invention relates to a device for controlling the gas exchange valves of an internal combustion engine that have respective hydraulic valve adjusters (11) associated with one gas exchange each comprising an adjustment plunger (13) acting on the gas exchange valve and two hydraulic working chambers (121, 122) that are limited by the adjustment plunger (13). The first working chamber (121) that impinges the gas exchange valve (10) in the closing direction is constantly filled with a pressurized fluid, and the second working chamber (122) that impinges the gas exchange valve (10) in the opening direction is alternately filled with a pressurized fluid and relieved via a first and second electric control valve (24, 25 and 26, 27, respectively) In order to reduce the cost of production of such a valve, two valve adjusters (11) each are alternately actuated by the same first and the same second control valve (24 or 26, 25 or 27) and the control valves (24, 25 or 26, 27) are switched during the closed state of the two gas exchange valves (10) that are actuated by said valve adjusters (11).

摘要： The invention relates to a method for determining injection valve time specifications and filling specifications in an internal combustion engine, said engine having a multitude of cylinders with a variable valve gear each provided with an intake pipe, at a specified change in torque. The method provides that, when determining a positive specified change in torque at a synchronization time, it is detected whether an injection process in a cylinder of the internal combustion engine is active and when this is the case, a basic injection time of this injection process is prolonged by a first length of time. According to the realizable fuel dynamics, the filling dynamics for a control device with completely variable valve control can be limited whereby enabling the desired air-fuel ratio to be readjusted at any time.

摘要： Disclosed is a device for controlling gas exchange valves comprising at least one valve actuator (16) and a pressure supply device (25) which provides the valve actuator (16) with high-pressure fluid. The valve actuator (16) comprises a working cylinder (17) with an actuating piston (21) which is coupled to the gas exchange valve (10) and which defines an upper pressure chamber (22) for closing the valve and a lower chamber (23) for opening the valve, in addition to a control valve (19) which controls the hydraulic pressure in the pressure chambers (22, 23). In order to reduce the production costs and electrical power requirements of said device, the upper pressure chamber (22) is connected directly and the lower pressure chamber (23) is connected by means of a throttle (18) to the pressure supply device (25) and the control valve (19) is connected to the lower pressure chamber (23) and a discharge line (27). According to the switching position, the control device (19) also connects the lower pressure chamber (23) to the discharge line (27) or blocks it off from said discharge line.

摘要： Disclosed is a device for controlling charge exchange valves, at least one of which is assigned to the combustion chamber of a combustion engine as an intake valve (11) and at least one of which is assigned thereto as an exhaust valve (12). The inventive device comprises electrohydraulic valve actuators (18), each of which is assigned to a charge exchange valve so as to actuate said charge exchange valve, and a pressure-feeding unit (26) which is provided with a jetting pump and an accumulator unit and feeds the valve actuators (18) with a pressurized fluid. In order to reduce the power consumption of the control device, the accumulator unit comprises two separate high-pressure reservoirs (31, 32), one of which is connected to the valve actuator (18) for the at least one intake valve (11) while the other one is connected to the valve actuator (18) for the at least one exhaust valve (12). The jetting pump (27) is optionally connected to one or the other high-pressure reservoir (31, 32) and to a return duct (37) leading to a fluid reservoir (29) by means of a switching member (30).

摘要： A method for controlling the opening of at least one inlet valve of a combustion chamber of a periodically operating reciprocating engine. The at least one inlet valve of the combustion chamber is opened during a first sub-period of an operating period of the reciprocating engine in order to charge the combustion chamber. At least one inlet valve of the combustion chamber is opened during a second sub-period of the operating period. The invention is characterised in that the second sub-period begins after combustion of the charge of the combustion chamber and does not overlap with the first sub-period.

摘要： The invention relates to a cylinder-charge control method. According to said method, residual gas in the cylinder is recycled internally and is intermittently shunted in front of the inlet valve(s), by controlling the closure times (AS) of at least one outlet valve of the respective cylinder and by opening (EO1) at least one inlet valve in the vicinity of the upper response point (OT) of the piston and at least one inlet valve is opened in at least two chronologically separate phases (EO1, ES1, EO2, ES2) during a charge cycle in the cylinder. Said method optimizes the operation of the motor in the warm-up period in terms of consumption, pollution emission and smooth running.

摘要： A device for the control of gas exchange valves in an internal combustion engine is disclosed, comprising a hydraulic valve actuator (11), provided for each gas exchange valve, with an actuator piston (13) acting on the gas exchange valve and two hydraulic working chambers (121, 122), defined by the actuating piston (13), of which the first working chamber (121), which pressurises the gas exchange valve in the closing direction, is permanently filled with a pressurised fluid and the second working chamber (122), which pressurises the gas exchange valve in the opening direction, may alternately be filled with and drained of pressurised fluid, by means of two electrically-operated control valves (25, 26). According to the invention, cost may be reduced whereby a single first electrical control valve (25) is provided for each valve actuator pair (11a, 11b), which is pressurised on the inlet side with the fluid pressure and is connected on the outlet side to the second working chamber (122) of the one valve actuator (11a). The fluid filling of the second working chamber (122) of the other valve actuator (11b) is carried out by means of a switching valve (29) and the fluid pressure in the second working chamber (122) of the one valve actuator (11a).
