Definitions
- the invention relates to an internal combustion engine according to the generic term of claim 1.
- Oil spray nozzles for cooling piston crowns.
- the Oil spray nozzles are positioned on the inside of a crankcase and via an axially parallel to the crankshaft penetrating the crankcase Oil channel supplied with lubricating oil. About this oil channel too the lubricating nozzles for the lubrication of the valve lifters.
- the oil spray nozzles and the lubrication nozzles are arranged in separate holes which is natural requires a large number of holes. To be flawless Ensuring cooling of the piston crowns is an exact positioning of the oil spray nozzles indispensable, which creates difficulties during assembly. Further provides the variety of holes for the oil spray nozzles and the lubricating nozzles represents a high manufacturing effort.
- the invention has for its object the manufacturing cost for the attachment to keep the oil spray nozzles and the lubricating nozzles as low as possible and without affecting the functionality of these parts.
- the oil spray nozzles used in the first holes are attached using a tab and only one screw both oil-tight and against twisting secured.
- Figure 1 shows an example of a cross section through a V-engine. Is shown a cylinder bank 1.
- the valve train consists of a roller tappet 2 with a camshaft 3.
- the push rod is not shown here.
- an oil spray nozzle 4 is provided, which counteracts the piston crown is directed.
- the supply of the oil spray nozzle 4 and one Lubricating nozzle 5 with oil takes place via a common oil channel 6 which covers the entire Cylinder bank 1 penetrates axially parallel to a crankshaft.
- the oil spray nozzle 4 and the lubricating nozzle 5 are concentric Bores 7, 8 introduced, which start from the inside of the crankcase and penetrate the oil channel 6 and end in a tappet guide 9.
- the oil spray nozzle 4 is in an outgoing from the crankcase and in the oil passage 6 opening first bore 7 installed, the lubricating nozzle 5 in one of the oil channel 6 outgoing and in the tappet guide 9 second bore 8 installed.
- the lubricating nozzle 5 is used with its peripheral jacket to guide the roller tappet 2, which has a longitudinal groove 11 on its plunger jacket 10 for this purpose in which the peripheral jacket of the lubricating nozzle 5 slides and the roller tappet 2 protects against twisting.
- the lubricating nozzle 5 be screwed or pressed into the second bore 8.
- the lubricating nozzle 5 supplies the roller tappet 2 with lubricating oil via a bore 14.
- the oil spray nozzle 4 is for its attachment and simultaneous positioning a tab 12 connected.
- the tab 12 is in turn by means of a screw 13 (Fig. 2) attached to the crankcase.
- the tab 12 provides an anti-rotation device the oil spray nozzle 4.
- a cylindrical shoulder 15 is used in the first hole 7 protrudes.
- the oil spray nozzle 4 is held by the screw 13. (Fig. 2).
- FIG. 2 An interior view of the crankcase is shown in FIG. 2.
- the oil spray nozzle 4 is attached to the crankcase by means of the screw 13 and bracket 12 and secured against twisting.
- the prefabricated unit from oil spray nozzle 4 and tab 12 can be installed positioned without much effort.
