- the invention relates to a method for measuring and / or adjusting a valve train device for an internal combustion engine, which comprises a camshaft in a separate cylinder head of the internal combustion engine for the stroke control of a gas exchange valve by means of an intermediate finger lever, in the cylinder head on a reciprocating piston of a hydraulic valve clearance compensation element is mounted.
- valve train devices with variable-displacement gas exchange valves
- the valve clearance compensation elements are to be supplied with pressure oil via the associated lines in the separate cylinder head for play-free surface closure of all relevant contact surfaces in the valve train.
- the JP-A-5 9218316 discloses a valve drive device for an internal combustion engine, which comprises a camshaft in a separate cylinder head of the internal combustion engine for stroke control of a gas exchange valve by means of an intermediate finger lever, which is mounted in the cylinder head on a liftable piston of a hydraulic valve clearance compensation element, wherein the piston Device has to attack a tool for a mechanical lifting operation for play-free surface closure of contact surfaces of the finger lever and a further valve train element at hydraulically pressure-free valve clearance compensation element.
- a valve drive device for an internal combustion engine which comprises a camshaft in a separate cylinder head of the internal combustion engine for the stroke control of a gas exchange valve by means of an intermediate finger lever which is mounted on the cylinder head on a support.
- a disadvantage of the prior art is for a measurement of the valve train at the end of the valve train assembly of a mass produced cylinder head the handling of the amount of oil present in a cylinder head, which is to be applied completely for a clean further work on the cylinder head.
- the invention has for its object to show for measuring and / or adjustment of a generic valve train device supported on a hydraulic valve play compensation element drag lever a method that allows a perfect, backlash-free surface closure between contact surfaces cooperating actuators of a gas exchange valve without hydraulic pressurization of the valve lash adjusters.
- the advantage of the invention is that with the inventive method for measuring and adjusting the valve train device the cylinder head no pressure oil must be supplied, the measurement and adjustment is done in a sense with a dry cylinder head. In the case of a standard measurement and adjustment thus eliminating a separate pressure oil system. It is also advantageous that the cylinder head is supplied to the other processing stations of the series oil-free.
- the tool can engage a joint ball provided on the piston for the finger follower in the transition region to a cylindrical portion of the piston.
- the piston is equipped with a separate means for positive and / or non-positive connection with the tool.
- the piston of a partially filled with oil deliverable valve clearance compensation element between a guide portion and a rocker arm condyle an outer circumferential groove for engagement of a tool with fork-like end portion. This arrangement is advantageous for a low profile valve lash adjuster.
- the piston is actuated in the stroke direction by a translationally or rotationally or pivotally acting tool, wherein the respective tool is subjected to force to maintain the surface closure between the valve drive side contact surfaces.
- the inventively designed piston of a hydraulic valve clearance compensation element - HVA - finds in a further embodiment of the invention preferably use for a variable displacement gas valve adjustable, with a roller equipped with a rocker arm with a Leerhubkurve and a lift curve comprehensive control of a against the action of a return spring of the Camshaft actuated pivot lever cooperates, the respective stroke variation corresponding pivot output position is controlled / regulated adjustable.
- a valve train device with variable displacement gas exchange valve is, for example, in the DE 199 13 742 A1 shown and described.
- a valve train device 1 for an internal combustion engine comprises in a separate cylinder head 2 a camshaft 3 for the stroke control of a gas exchange valve 4 by means of an interposed cam follower 5, which is mounted in the cylinder head 2 on a liftable piston 6 of a hydraulic valve clearance compensation element - HVA - 7 ,
- the piston 6 of the HVA 7 has means 8 for attacking a tool 9 for a mechanical lifting operation for backlash-free surface contact surfaces 10, 11 of the finger lever 5 and another valve drive element 12 at hydraulic depressurized valve clearance compensation element or HVA 7.
- the piston 6 of the HVA 7 is equipped with a separate device 8 for positive and / or non-positive connection with the tool 9.
- a translationally acting according to arrow A tool 9 may be provided or else a rotatably or pivotally acting tool.
- the respective tool 9 is subjected to a force by means of a tension spring 16.
- valve drive device 1 comprises a variably variable gas exchange valve 4, wherein a equipped with a roller 17 rocker arm 5 cooperates with a Leerhubkurve 11 and lift curve 18 comprehensive control path 19 of an actuated against the action of a return spring 20 of the camshaft 3 pivot lever 21, the respective stroke variation corresponding pivot output position by means of a control device 25 is controlled / regulated adjustable.
- the documentation of the valve strokes takes place only after a predetermined running time of the valve train device 1.
- the drag lever is exchanged for this gas exchange valve with another classified drag lever 5.
