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.

An arrangement for distributing oil in a camshaft of an internal-combustion engine comprises a cylindrical insert which extends axially in the camshaft and carries two separate oil flows in the camshaft. The insert has a centrally arranged oil duct for one oil flow and a hollow space for another oil flow which is constructed between the insert and the camshaft and forms a portion of the arrangement. Both oil flows are fed to the camshaft or discharged from it by way of radial ducts.

An intake system which includes an intake distributor as well as intake pipe sockets leading to inlet ports in cylinder heads of an internal-combustion engine is held on the internal-combustion engine by means of first and second decoupling elements. For the mounting of the intake distributor, a plurality of tension devices are required which tension decoupling elements supported on a flange facing of the cylinder head. The forces which are transmitted in this case by the tension devices to the intake distributor may also be supported on the cylinder head by way of additional decoupling elements which are under compression due to the tension devices.

An oil guiding housing is arranged below the crankcase of an internal-combustion engine and has a storage tank for lubricating oil and a housing part with a connection for an oil filter. In the pan part of the oil guiding housing situated directly below the crankshaft, a forward flow and return flow part for lubricating oil is integrated. The oil guiding housing ensures a targeted guiding of all lubricating oil flows and provides a good degassing of the oil.

The lubricating-oil circulating system of a piston internal-combustion engine is supplied by a main oil pump arranged in the oil pan and driven by the crankshaft. A second oil pump, which is also driven by the crankshaft, supplies hydraulic pressure to hydraulic camshaft rotating devices. The second oil pump is integrated in an intermediate timing gear and is driven by it, the camshafts being driven by the crankshaft by way of this intermediate timing gear.
摘要:
A plastic oil pan for internal-combustion engines is disclosed which includes an oil drain plug screwed into a threaded insert. This oil drain plug is braced with respect to the threaded insert. In order to avoid an undesirable discharge of oil when the oil drain plug is fixed, a radial seal is operative between the oil drain plug and a recess in a local thickening of the oil pan.

A chain tensioner acts by means of tensioning elements on the taut section and the slack section of an endless chain whcih preferably cooperate with chain sprockets of parallel cam shafts of an internal combustion engine. The tensioning elements are provided with relatively movable pistons which are nested one within the other, have a common pressure space and are accommodated in a cylindrical housing. The housing is provided with a fastening eye which extends axially parallel to the housing whereby the fastening eye is secured at an internal combustion engine housing part by a bolt. Oil is conducted to the pressure space between the pistons by way of the bolt.

An actuating arrangement connected with throttle valves of suction pipes of an internal combustion engine which are to be actuated synchronously. The throttle valves include bearing shafts and cooperate by way of levers with a linkage of the actuating arrangement. For the compensation of tolerances of the actuating arrangement, especially angular tolerances of the throttle valves, yielding members are provided between the linkage and the bearing shafts, and a device stresses the throttle valves into the closed end positions.
摘要:
A multi-cylinder internal combustion engine with liquid cooling comprises a cylinder head and a cylinder crankcase connected with the cylinder head; the crankcase includes cylinder liners circumcirculated by the cooling medium. For reducing the weight of the internal combustion engine, the cooling medium quantity is reduced and the cylinder head and the cylinder liners are acted upon with cooling medium by a cross-flow cooling system. Additionally, an internal combustion engine unit of relatively short construction and relatively light weight is created by the particular construction of the cylinder liners.
摘要:
A reciprocating piston internal combustion engine equipped with a vibration-damping balancing shaft that is rotatably supported in a bearing housing which in turn is secured at the cylinder crankcase by means of a threaded connection; in order to support the rotational forces of the balancing shaft between bearing housing and cylinder housing without play, at least one of the bolts of the threaded connection includes a conically shaped neck that cooperates with a corresponding chamfering in the bearing housing.
