摘要:
An arrangement (1) which serves in particular as a fuel injection system for high-pressure injection in internal combustion engines comprises a fuel distributor (2) and multiple fuel injection valves (3, 4). Here, each of the fuel injection valves (3, 4) is arranged on a cup-like element (9, 10) of the fuel distributor (2). At least one of the fuel injection valves (3, 4) is fastened to the associated cup-like element (9, 10) by way of a retention element (15). The retention element (15) has a support surface (16). The cup-like element (9) has, on an underside (20), a contact surface (21) by which the cup-like element (9) is supported, via a damping layer (11), on the support surface (16) of the retention element (15). The retention element (15) is fixed to the cup-like element (9). The fuel injection valve (3) also has a collar (25) which is supported on the retention element (15). Damping of vibrations, and thus a reduction in noise emissions, is possible by means of the damping layer (11).

A fuel distributor (1) which serves, in particular, for fuel injection systems of mixture-compressing, spark-ignition internal combustion engines comprises a tubular main body (2), a first holder (7) and a second holder (8). Here, the first holder (7) is connected to the tubular main body (2) at a first fastening point (10) of the tubular main body (2). Moreover, the second holder (8) is connected to the tubular main body (2) at a second fastening point (12) of the tubular main body (2). The tubular main body (2) has at least one bend (4) at least between the first fastening point (10) and the second fastening point (12). As a result, a main body (2) of serpentine-shaped design can be realized. As a result, for example, thermal length changes of a cylinder head, on which the fuel distributor (1) is mounted, can be compensated for.

The invention relates to an oil separating device (2) for crankcase gases of an internal combustion engine comprising a pre-separating device (28), a cyclone separating device (30), a fine separating device (32) and, optionally, a valve device (36), which are all provided in a cascade-like manner on a cylinder head cover (4) of the internal combustion engine. The aim of the invention is to create an oil separating device for use in different engines having different crank gas quantities. To this end, the oil separating device is designed so that coils (48) of a different radial depth of the flow path can be inserted, as desired, into a housing section for the cyclone separating device (30).

A fuel distributor (1) which serves in particular for fuel injection systems of mixture-compressing, applied-ignition internal combustion engines comprises a tubular main body (3). Here, an inner wall (4) of the tubular main body (3) delimits an elongate fuel chamber (5). The tubular main body (3) is formed from a plastic. On the tubular main body (3) there is provided at least one passage opening (7 to 15) which, at the inner wall (4) of the tubular main body (3), issues into the fuel chamber (5) eccentrically with respect to a longitudinal axis (2) running centrally through the elongate fuel chamber (5). In this way, the strength of the fuel distributor (1) can be improved.
摘要:
A fuel distributor (1), which serves in particular for fuel injection systems of mixture-compressing, applied-ignition internal combustion engines, comprises at least one housing part (2) enclosing a fuel chamber (3), comprises at least one screw element (6), and comprises at least one sealing ring (14). Here, there is provided on the housing part (2) a recess (4) into which the screw element (6) is screwed in a self-tapping manner. Here, the sealing ring (14) forms a seal between the screw element (6) and the housing part (2). Chips formed during the screwing-in process thus remain reliably separated from the fuel chamber (3). The screw element (6) has an external thread (7), wherein on the screw element (6) there is formed an annular groove (15) which receives the sealing ring (14), and wherein the sealing ring (14) leads the external thread (7) of the screw element (6).
摘要:
The invention relates to an oil-separating device (2) for crankcase gases in an internal combustion engine, comprising a pre-separating device (28), a cyclone separating device (30), a fine separating device (32) and an optional valve device (36), which are provided on the rocker cover (4) of the internal combustion engine in the form of a cascade. The aim of the invention is to simplify the construction of the oil separating device and to make assembly easier. Said aim is achieved, whereby the pre-separating device (28), the cyclone separating device (30), the fine separating device (32) and the optional valve device (36) are arranged on the outside of the rocker cover (4) and covered by a housing part-shell (6), which, together with the external side (20) of the rocker cover (4) forms a housing for the separating device (2).
