Valve timing regime in an i.c. engine capable of operating in two-stroke mode

An internal combustion engine capable of operating in a two-stroke mode, has an engine control system 12 that acts on the valve actuating mechanism 14 to set an operating regime (Figure 3) in which the timings of the intake and exhaust valve events are, instead of being symmetrical about BDC, both advanced to such an extent that, during each rotation of the engine crankshaft, the major proportion of each event occurs during the second half of the piston downstroke. Preferably at least two-thirds of the intake event occurs during the downstroke.

VALVE OPERATING SYSTEM IN INTERNAL COMBUSTION ENGINE

An actuator is connected to one of components forming a power transmitting device capable of transmitting a power provided by a valve operating cam provided on a cam shaft, so that the actuator can drive an engine valve in a lift amount which is obtained by addition of a lift amount of the engine valve based on a cam profile of the valve operating cam and a lift amount of the engine valve based on the operation of the actuator. Thus, a portion of the lift amount of the engine valve is borne by the valve operating cam, whereby a valve-opening power borne by the actuator can be reduced, as compared with a system designed so that the engine valve is driven by only the actuator only. The amount of electric power consumed by the actuator can be smaller.

System and method for servo control of nonlinear electromagnetic actuators

Servo control using ferromagnetic core material and electrical windings is based on monitoring of winding currents and voltages and inference of: magnetic flux, a force indication; and magnetic gap, a position indication. Third order nonlinear servo control is split into nested control loops: a fast nonlinear first-order inner loop causing flux to track a target by varying a voltage output; and a slower almost linear second-order outer loop causing magnetic gap to track a target by controlling the flux target of the inner loop. The inner loop uses efficient switching regulation, preferably based on controlled feedback instabilities, to control voltage output. The outer loop achieves damping and accurate convergence using proportional, time-integral, and time-derivative gain terms. The time-integral feedback may be based on measured and target solenoid drive currents, adjusting the magnetic gap for force balance at the target current. Incorporation of permanent magnet material permits the target current to be zero, achieving levitation with low power, including for a monorail deriving propulsion from the levitation magnets. Linear magnetic approximations lead to the simplest controller, but nonlinear analog computation in the log domain yields a better controller with relatively few parts. When servo controlled solenoids provide actuation of a pump piston and valves, electronic LC resonance measurements determine liquid volume and gas bubble volume.

Apparatus for controlling position of electromagnetically operated engine valve

본 명세서에서는 내연 기관용 전자기 작동식 엔진 밸브의 위치 제어 장치에 대해 개시하고 있다. 엔진 중지 동안에, 제어기는 크랭킹 작동 실패가 엔진 중지를 발생시켰는지[단계(S1)] 엔진 실속이 엔진 중지를 발생시켰는지[단계(S2)]를 검출한다. 점화 스위치가 엔진 중지 상태에서 온으로 되고 점화 스위치가 크랭킹 작동 실패로 인해 엔진 중지 상태에서 오프로 되는 경우, 엔진 밸브(흡기 밸브 또는 엔진 밸브중 어느 하나)는 엔진 중지 후 크랭킹 작동에서의 실패 횟수 또는 엔진 냉각수 온도에 기초해서 소정 시간 동안 밸브 개방 위치 또는 밸브 폐쇄 위치에 유지된다[단계(S1)에서 단계(S8)까지]. 따라서, 엔진 실속 또는 공전 중지 동안 엔진의 재시동시 엔진 밸브를 초기화하는 것이 필요하다. 엔진은 전력 소모를 절감하면서 빠르게 재시동될 수 있다. In this specification, the position control apparatus of the electromagnetically actuated engine valve for internal combustion engines is disclosed. During the engine stop, the controller detects whether the cranking operation failure caused the engine stop (step S1) or whether the engine stall caused the engine stop (step S2). If the ignition switch is turned on from the engine stop state and the ignition switch is turned off from the engine stop state due to the cranking operation failure, the engine valve (either the intake valve or the engine valve) fails in cranking operation after the engine stop. It is maintained in the valve open position or the valve closed position for a predetermined time based on the number of times or the engine coolant temperature (from step S1 to step S8). Therefore, it is necessary to initialize the engine valve upon restarting the engine during engine stall or idle stop. The engine can be restarted quickly, reducing power consumption.

The valve also includes a core element having an annular horizontal cross-section and is disposed intermediate the upper and lower electromagnetic elements. A coil is disposed within the central channel of each of the electromagnetic elements. A valve stem is disposed within the central chamber of the electromagnetic elements. A spring is disposed within the central chamber of the electromagnetic elements for biasing the electromagnetic elements in a neutral position. A connecting plate connects the core elements to the valve stem. Applying current to the coil in the upper electromagnetic element causes the valve to close, and interrupting the current to the coil in the upper electromagnetic element and applying current to the coil in the lower electromagnetic element causes the valve to open.

Method and unit of position sensor for determining relative position between the first object and the second object

FIELD: measuring equipment. SUBSTANCE: method for determining relative position between the first housing and a coil is carried out using a position sensor unit. The position sensor unit comprises the first housing, a coil (11), a control unit and a sensor circuit (12). The first housing is mutually movable in the axial direction with respect to the coil (11). The sensor circuit (12) comprises a comparator (15) connected to the first branch comprising the coil (11), a power switch (16) and a reference resistance (18) connected in series with each other. The comparator (15) is configured to obtain and compare an instantaneous measuring voltage through the reference resistance (18) and an instantaneous transfer voltage, to generate a change in the state of the digital output signal based on the mutual correlation between the measuring voltage and the transfer voltage. The method consists in sending an ascending branch of the digital input signal pulse from the control unit to the power switch (16) to create a change in the state of the power switch (16) from opened to closed. In the control unit, the first change in the state of the output signal from the comparator (15) is detected. The realtive position between the first housing (10) and the coil (11) is determined based on the time delay between the ascending branch of the input signal pulse and the first change in the state of the output signal. The method may also consist in detecting the second change in the state of the output signal in the control unit. The realtive position between the first houding (10) and the coil (11) may be determined based on the delay between the first change in the state of the output signal and the second change in the state of the output signal. The position sensor unit is opened. EFFECT: increased accuracy of determining the realtive position between two objects and reduced energy consumption. 11 cl, 8 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 630 631 C2 (51) МПК F01L 9/04 (2006 ...

Valve system

In a casing, valves lie in a plane perpendicular to the motor (1) drive unit. The coupling mechanism (10) connects the drive unit for operation of the valve rods (19).

valve system

Durch die Trennung verschiedener Abgasstränge in einer Verbrennungskraftmaschine ist es notwendig geworden, mehrere Abgasrückführventile einzusetzen, die jeweils über einen eigenen Antrieb verfügen. Mit dem erfindungsgemäßen Gegenstand ist ein Ventilsystem geschaffen worden, welches mehrere Ventile über eine Antriebseinheit antreibt und somit geringere Kosten durch Reduzierung der Anzahl der Bauteile und des Montageaufwands entstehen. Dies wird dadurch erreicht, daß eine Kupplungseinheit die eine Antriebseinheit mit den verschiedenen Ventilstangen verbindet. Due to the separation of different exhaust gas lines in an internal combustion engine, it has become necessary to use several exhaust gas recirculation valves, each of which has its own drive. With the object according to the invention, a valve system has been created which drives a plurality of valves via one drive unit and thus lower costs are incurred by reducing the number of components and the assembly effort. This is achieved in that a clutch unit connects a drive unit to the various valve rods.

Solenoid valve actuator

Valve system

Internal combustion engine

Internal combustion engines comprising at least one cylinder having one or two admission valves and one or two outlet valves for controlling the gas exchange, and at least one electric or hydraulic actuator provided with a regulating piston, by which means a pair of admission valves or a pair of outlet valves can be actuated via a coupling element, are known. The coupling element is a plate which is rotatably mounted on the regulating piston, and to which the gas exchange valves are rigidly fixed. The rigid connection enables the gas exchange valves to be actively opened by the pressure forces of the actuator, and actively closed by the traction forces of the actuator. It is disadvantageous that there is no precise play and tolerance compensation with said arrangement, which would ensure a uniform movement of the gas exchange valves. The rotating mounting of the coupling element allows a slightly different course of the two gas exchange valves, such that they cannot be precisely actuated and valve play compensation is not possible or only in a very costly manner. The internal combustion engine according to the invention enables conventional valve play compensation to be easily implemented. According to the invention, the coupling element (8) is a rotatably mounted valve lever or a cross member mounted in a linear guide (7), and is coupled to the admission or outlet valves (2, 3) in such a way that only pressure forces can be transmitted to the admission or outlet valves (2, 3).

The permanent magnet assembly comprises inner and outer annular axially magnetized permanent magnets radially spaced by a ferromagnetic ring so as to be aligned with the inner and outer core extensions.

An electronic control type variable valve timing apparatus for engine

The present invention relates to an electronic control type variable valve timing device capable of adjusting a valve sealing timing of an engine in an electronic control scheme. To this end, the electronic control type variable valve timing device comprises: a housing for connecting lower and upper push rods; a cylinder formed with upper and lower chambers, having a lower plunger positioned at the lower chamber to be vertically moved and an upper plunger positioned to be in contact with the upper chamber, and mounted with a first check valve to allow hydraulic fluid of the upper chamber to flow only to the lower chamber; a flow path formed at the outside of the cylinder to allow the hydraulic fluid to flow to the upper chamber from the lower chamber; and a solenoid valve mounted on the housing to open and close the flow path. When the lower plunger is elevated, the hydraulic oil of the lower chamber is closed to allow the cylinder to push and lift the upper plunger by a hydraulic pressure. Also, when the solenoid valve is opened, the hydraulic oil in the lower chamber flows to the upper chamber through the flow path such that the upper plunger is moved downward before the lower plunger is moved downward.
