An internal combustion engine has at least one cylinder and at least one gas exchange valve () controlled by a first cam () on a first camshaft () and by a second cam () on a second camshaft (), at least one camshaft () having an adjustable phase position in order to modify the control times of the gas exchange valve (). The first cam () acts upon actuating means () and the second cam () upon actuating means () which actuate the gas exchange valve (). The actuating means () are designed in such a way that the gas exchange valve () opens only when both the first cam () and the second cam () are acting upon the actuating means (). A simple structure with very high degrees of freedom for the control is achieved in that the actuating means () comprise a lever which actuates the gas exchange valve () and is actuated by both cams ().

Internal combustion engine

The invention relates to an internal combustion engine comprising a variable valve drive device provided with at least one camshaft having at least one cam arrangement. Said cam arrangement comprises a cam which can be displaced essentially radially in relation to the camshaft, and at least one, preferably two, base circle disks fixed to the camshaft.

An intake system for internal combustion engines, comprising suction pipes of different lengths, which can be connected individually--preferably in accordance with the engine speed--to the intake passage in the cylinder head leading to the intake valve. The main intake pipe is connected to each intake passage by means of a connecting piece, and three suction passages of different lengths departing from the main intake pipe open into this connecting piece either in the direction of its axis or on opposite sides thereof, the connecting piece containing a butterfly control valve which is centrally mounted on a shaft parallel to the longitudinal axis of the engine, and which--in its two extreme positions and in its center position--establishes the flow connection between one of the suction passages and the intake passage.

Intake system for internal combustion engines

Dry cylinder-liners are partly inserted into the liquid cooled lower part a common cylinder head, which is fastened to an upwardly extended crankcase by means of crankshaft main bearing studs having their threads at the level of the inserted parts of the liners. Thus, cylinders and crankcase are stress-relieved, permitting a simple design and the use of less expensive materials and production methods.

Internal combustion, reciprocating piston, liquid cooling engine

An assembly of auxiliary equipment for a water-cooled internal combustion engine having an oil pump, a water pump and an oil cooler/oil filter unit, wherein the oil pump, water pump and oil cooler/oil filter unit are provided as separate interchangeable subassemblies and are combined and interconnected into a constructional unit that can be mounted on the engine.
