In an oil pan for an internal combustion engine particularly for use with a motor vehicle, the oil pan consists of an outer latticed girder structure of a light-weight high-strength material and an inner thin-walled shell of plastic material forming an integral oil pan structure.

Oil pan for an internal combustion engine

In an engine block of an internal combustion engine having a clutch housing provided with cut-outs, a thin-walled liner is fitted into the clutch housing to cover the cut-outs so as to provide a clutch housing structure of a relatively low weight.

Crankcase of an internal combustion engine

In an internal combustion engine with an engine block, a cylinder head with a camshaft mounted on the engine block, a crankshaft mounted on the engine block opposite the cylinder head and a camshaft timing drive interconnecting the crankshaft and the camshaft, a camshaft timing drive enclosure is disposed at one end of the engine and fully encloses the camshaft timing drive, and the enclosure has extensions extending over the side walls of the engine block and covering openings formed in the side walls of the engine block providing for a light-weight arrangement with noise attenuating properties.

Internal combustion engine

In a crankcase of an internal combustion engine with lower and upper crankcase parts joined together along a separation plane extending through the axis of crankshaft bearings mounted in the transverse walls of the crankcase, the upper crankcase part has side walls with cut-outs formed therein and a cup-shaped member is disposed within the crank chamber formed between the transverse walls of the crankcase to cover the cut-outs. The cup-shaped member has an opening adjacent the respective cylinder of a cylinder block extending from the upper crankcase for accommodating a connecting rod extending between the crankshaft and a piston in the respective cylinder of the cylinder block.

In a hydraulic tensioning arrangement for tensioning a flexible drive for a camshaft of an internal combustion engine including a crankcase and a cylinder head wherein a main lubricating oil channel extends longitudinally along the inside of the crankcase and has an opening at the front end of the crankcase, a hydraulic housing with a cylinder receiving a plunger is mounted on the front end of the crankcase so as to cover the main lubricating oil channel opening and passage elements are provided for supplying oil from the main lubricating oil channel to the cylinder to bias the plunger against tensioning elements engaging the flexible drive.

Hydraulic tensioning arrangement for tensioning flexible drive means for

In an engine block comprising a casting including side walls extending along a row of cylinders and front and rear walls extending between the side walls with top flanges for mounting a cylinderhead and bottom flanges for mounting an oil pan, the side walls have sections extending forwardly beyond the front wall to define therebetween a timing drive chamber.
