The bore (26) of each lever (25) encompasses an outer body (19) of a pressure piston (7) of the associated support element (1). The pressure piston (7) has at least one flat surface (20). A section of the bore (26) which has been left intact (27) lies opposite said flat surface. A circular groove (28) is provided in the outer body (19), its circumference being offset from the flat surface (20). When the lever (25) is turned as a result of impingement on the rod (31), the support element (1) is switched in such a way that either the intact section (27) extends with partial areas in the circular groove (28) so that the support element (1) remains 'on' or each flat surface (20) lies opposite a section (27). This allows the pressure piston (7) to complete a movement in relation to the housing and the support element is switched off. The invention is also particularly characterised in that the rod (31) can be displaced by an electromagnetic actuator, for example.

Control apparatus for internal combustion engine

An IIS system (2) that performs control related to intermittent stopping of engine operation by idling stop control is applied to an internal combustion engine including a VVT mechanism (6) that makes the valve timing of an engine valve variable and has an intermediate lock mechanism (18) that mechanically locks the valve timing at an intermediate lock position between a most retarded position and a most advanced position. The IIS system (2) is configured to inhibit the engine operation from being intermittently stopped at the occurrence of a failure of the VVT mechanism (6) to avoid the internal combustion engine from being prevented from being restarted after the intermittent stop depending on the occurrence of the failure of the VVT mechanism (6).

Valve timing control system for internal combustion engine

A valve timing system for an internal combustion engine includes a phase alteration mechanism interposed between a driving rotator and a driven rotator and having a direction turning point at which the phase alteration direction is reversed when a movable portion of the mechanism travels from a beginning to a termination, and an operation control device for displacing the movable portion when undergoing an energization control, the movable portion being displaced toward the beginning when the energization control fails to be carried out. The rotation phase is set at a middle position between a maximum retard position and a maximum advance position when the movable portion is located at the beginning.

Direct injection internal combustion engine

A direct injection engine has a fuel injection valve that directs a spray of fuel to each side of a spark plug electrode. The fuel mixes with the air to define a region of relatively richer air-fuel mixture and a region of relatively leaner air-fuel mixture. The electrode is positioned within the relatively leaner region.

In-cylinder fuel injection-type internal combustion engine

A cylinder head (6) has an intake passage (15) in one side part thereof and an exhaust passage (19) in the other side part thereof as viewed in a side view of a cylinder (2) in which the axis (3) of a cylinder bore (4) in an internal combustion engine (1) is coincident with a vertical line. A fuel injection valve (45) is provided which can inject fuel (44) obliquely downward from an outer side of the one side part of the cylinder head (6) into the cylinderbore (4). A spark plug (47) is located generally on the axis (3) of the cylinder bore (4) with its discharging part (46) positioned in the cylinder bore (4). The fuel (44) injected from the fuel injection valve (45) forms a V-shape with the discharging part (46) between them as viewed in a plan view of the cylinder (2). The fuel injection valve (45) inj ects the fuel (44) during an intake stroke. According to the above constitution, high fuel efficiency can be achieved with reliability even when the average air-fuel ratio of the air-fuel mixture in the cylinder bore (4) is high, in other words, the air-fuel mixture is lean as a whole, such as when the internal combustion engine (1) is operating at low load.

Variable lost motion valve actuator and method

A lost motion engine valve actuation system (10) and method of actuating an engine valve are disclosed. The system may comprise a valve train element, pivoting bridge (200), an adjustable tappet (320) and a valve stem (400). The pivoting bridge (200) may include a first end (220) for contacting the adjustable tappet (320), a second end (230) for contacting the valve stem (400) and a pivot point (210) between the first and second ends for contacting the valve train element. The amount of lost motion provided by the system may be selected by varying the position of the adjustable tappet (320) relative to the pivoting bridge (200). Variation of the adjustable tappet position may be carried out by placing the adjustable tappet (320) in hydraulic communication with a control trigger valve (330). Actuation of the trigger valve (330) releases hydraulic fluid allowing for adjustment of the adjustable tappet position.
