摘要:
A cylinder head of an internal-combustion engine is disclosed which includes a horizontally divided carrier in which camshaft bearings as well as receiving devices for bucket tappets are arranged. The arrangement is constructed rigidly as a result of longitudinal and transverse webs and, by removing the receiving devices from the cylinder housing, permits the use of a simple casting method for the cylinder head housing.

For actuating the inlet and outlet valves, two parallel overhead camshafts respectively are assigned to the two cylinder banks of a multi-cylinder V-engine and are driven by an intermediate timing gear by means of chain drives. The intermediate timing gear is driven by the crankshaft by means of gear wheels. The camshaft drive is arranged between the end bearing of the crankshaft and the flywheel.

An internal combustion engine, especially for motor vehicles, includes separate oil return and vent channels extending between a crank space of a cylinder crankcase and a valve-actuating space formed by a cylinder head and a cover. For the defined and separate guidance of the media passing through the oil return channels and vent channels, the oil return channels are arranged at a distance to the vent channels and the vent channels are connected to an air guide device inside of the valve-actuating space.

A torsional-vibration damer is fastened on a crankshaft. It comprises a hub and a mass-body which is arranged to be offset in radial direction with respect to the hub. Between the torsional-vibration damper and the crankshaft are separate connections, one for torque transmission and the other for absorbing bending moments through radial supporting elements.

An internal combustion engine includes a crankcase with a crankshaft which drives at one end face of the crankcase, auxiliary aggregates--oil pump--and endless elements. The oil pump and the endless elements are covered off by means of a covering which consists of a sheet metal part including two thin-walled layers and is constructed pot-shaped in cross section. This light-weight covering which is simple in construction is secured at the end wall of the crankcase by means of an edge flange and by means of bolts.

The intake system is connected to a cylinder head of the internal-combustion engine that, for each cylinder, has two intake ducts. The intake ducts are located on a joint plane extending vertically with respect to the cylinder bore axis. A curve-shaped pipe body piece of the intake system leads away from the cylinder in which the ducts are continued and have an interlaced course with respect to one another. This course is developed in such a way that, in a horizontal plane extending away from the cylinder head, the ducts are located next to one another--seen in transverse direction of the internal-combustion engine.
摘要:
A crankshaft of a ferro-metallic material for reciprocating engines, particularly for internal combustion engines, includes bearing pins and crank pins whereby the crank pins are delimited by webs extending transversely to a longitudinal center axis of the crankshaft which are constructed as counterweights. For optimizing the crankshaft as regards weight and structural length combined with good mass balancing, the crank pins are provided with hollow bores in the direction of their center axis and the counterweights with heavy-metal bodies.

These crankshaft bearings consist of a light-metal alloy and are formed by a bearing section of a crankcase and a bearing cap. In order to avoid a bearing clearance causing noise, a core made of iron metal is poured at least into the bearing cap, said core, by means of a bearing area, directly surrounding the crankshaft journal of a crankshaft, and having lugs for bores connected by a transverse part. The bores are penetrated by the screws in order to fasten the bearing.
摘要:
A connecting line between the compressor of an exhaust gas turbocharger and a suction pipe of an internal combustion engine. For the compensation of tolerances and for the installation simplification, the connecting line includes at least two nested pipe sections disposed one within the other and cooperating by way of sealing means; the pipe sections are connected with each other by means of a disengageable device including a bridge.
摘要:
An air guide device on the rear of a motor vehicle has an airfoil located between side elements. The device includes a spoiler unit located at a distance from the airfoil with an integrated air intake grille in a trunk lid. The spoiler unit is made in one piece with the side elements to hold the airfoil which runs crosswise. Intake openings for supplying engine air are located in each of the side elements.
