摘要:
To additionally reduce the noxious emissions of motor vehicles, the gasoline or diesel engines are splitted into a primary and a secondary engine, both having own partial crankshafts. The primary engine is conventionally used, and it drives the vehicle auxiliaries by a novel engine cross-shaft, while the secondary engine is automatically started and clutched-in for higher loads, and automatically separated and stopped under no-load conditions. The clutching-in and separation of the secondary engine is performed by a novel clutch between the two partial crankshafts, controlled by the accelerator pedal without the driver's help, which also effects an automatical synchronization of the crank positions of the partial crankshafts. An additional hand-switch can exclude the clutching-in of the secondary engine for motor-queuings. The split-engine establishes a whole engine family, contributes a multiplicative reduction of noxious emissions, saves additionally fuel, and enables economy-priced engine optionals.

The invention relates to a method for operating a power train system (10) of a commercial vehicle (12), comprising a power train (16) mechanically driven by a drive motor (14) of the commercial vehicle (12), a connecting element for transmitting mechanical drive force from the drive motor (14) to the power train (16) and a coupling (20) for interrupting the drive force transmitted to the power train (16) via the connecting element, wherein the power train system (10) further has at least one bearing (22, 24, 26, 28, 30) which is lubricated with oil by means of an oil circuit (32) in the drive motor (14). Provided according to the invention is that the coupling (20) is closed by a control signal when a period of time At lapses after the drive motor (14) is started up and/or a minimum oil pressure is present in the oil circuit (32). The invention further relates to a power train system (10).

The invention relates to a cover plate (2) for a crankcase (1) of an internal combustion engine. Said cover plate (2) extends over the entire surface area of the crankcase (1). The auxiliary aggregates (6, 7) and filters are mounted on the cover plate (2). In addition, the cover plate (2) comprises channels for guiding media. The invention is advantageous in that it facilitates mounting.

Un carter de distribution (11) et un carter de cylindres (12) sont construits de façon à se partager une patte (15, 16) d'attache d'alternateur (5). Un déplacement de l'alternateur (5) vers le carter (12) devient possible puisque l'avance des oreillettes (6) n'entame plus la largeur de la surface d'étanchéité du logement (3), qui s'étend dans la patte entre les oreillettes.

An accessory drive assembly (10) is provided for a vehicle and includes housing (11) having first and second chambers for first and second accessory drive components (12,13), respectively. The first and second accessory drive components may be a water pump and steering pump, a water pump and alternator, or some other combination of accessory drive components. First and second driven elements are disposed within the first and second chambers, respectively. The driven elements correspond appropriately to the accessory drive component. That is, the driven element for a water pump may be an impeller, and a driven element for a power steering pump may be a gerotor assembly. A common driveshaft (22) is supported in the housing and is coupled to the first and second driven elements. In an alternative embodiment of the present invention, the housing may be a rocker cover. The rocker cover includes a chamber formed therein for an accessory drive component such as a water pump. A driven element is disposed within the chamber and a driveshaft is supported by the rocker cover housing and is coupled to the driven element.
