In a camshaft adjustment device for an internal combustion engine, with at least one sensor unit and one actuator unit, at least two functional units are supported on a common carrier unit and combined into a module for mounting on the internal combustion engine.

Camshaft adjustment device for an internal combustion engine

In a venting arrangement for an internal combustion engine including a crankcase with a cylinder block, a cylinder head mounted on the cylinder block, a cylinder head cover mounted onto the cylinder head, and an oil separator integrally formed with the cylinder head cover, the oil droplets contained in the vent gases are separated from the vent gases as the vent gases are drawn through the oil separator and the oil-free vent gases are then supplied to the engine air intake duct. The oil is collected and drained by way of a siphon consisting of a cavity formed in the cylinder head and a drain pipe extending from the oil separator in the cylinder head cover into the cavity which, at its bottom, includes a bore through which a cylinder head bolt extends for mounting the cylinder head onto the cylinder block.

Venting arrangement for an internal combustion engine

In a crankcase venting system for an internal combustion engine having an engine intake duct including a throttle valve, a partial load venting line extending from the engine to the intake duct downstream of the throttle valve and including a vent line throttle and a full load venting line connected to the engine and leading to the intake duct upstream of the throttle valve, an aspiration line extends between the intake duct upstream of the throttle valve and the partial load venting line for controlling the vacuum generated in the partial load venting line.

Crankcase venting system for an internal combustion engine

In a venting arrangement with integrated oil separator for venting gases from the crankcase of an internal combustion engine having a cylinder head with a cylinder head cover, the cylinder head cover includes integrally formed therewith a housing divided into a raw gas space receiving vent gases from the engine crankcase and having an exit opening directed toward the cylinder head and a purified gas space having an inlet opening disposed adjacent the exit opening of the raw gas space and both openings are disposed above a collection space which is formed in the cylinder head and in which the raw gas flow from the raw gas space is reversed and redirected into the purified gas space whereby the oil droplets are separated from the vent gas and collected in the collection space to be returned to the engine crankcase.
