  • Publication number: 20070169991
    Abstract: A device for heat and noise insulation has a first carrier layer rigidly connected with a component to be insulated, particularly an oil-carrying element of an internal combustion engine, as well as an insulating layer with a plurality of individual damping elements, particularly fiber or honeycomb elements which are individually connected with the carrier layer and/or joined to it in articulated manner. An air cushion is formed between the individual damping elements within the insulating layer and/or between the carrier layer and the insulating layer. The cushion can be changed by adjusting several of the damping elements, the entire insulating layer and/or the carrier layer. A method for insulating comprises connecting the carrier layer to a component to be insulated and attaching a plurality of the damping elements to the carrier layer, with the air cushion being formed between the damping elements, within the insulating layer or between the carrier layer and the insulating layer.

  • Patent number: 7240669
    Abstract: In a method of operating an internal combustion engine by supplying a gaseous fuel from a gaseous fuel tank to a combustion air feed line in which a compressor is arranged to the engine, part of the gaseous fuel is added to the combustion air feed line upstream of the compressor so as to form an intense pre-mixture with the air in the compressor and additional fuel is added to the gas/air pre-mixture downstream of the compressor.

  • Patent number: 6412452
    Abstract: In an internal combustion engine, with a cylinder head having a coolant space associated with each combustion chamber, wherein the coolant space comprises, for each cylinder of the engine, a first coolant chamber and a second coolant chamber separate from one another, the coolant space has a coolant inlet which extends to the outside and is connected to a coolant supply line for directly supplying coolant from the outside to the first and second coolant chambers.

  • Patent number: 6223702
    Abstract: In an internal combustion engine comprising an engine block consisting of a crankcase, at least one cylinder sleeve extending from the crankcase and a coolant jacket disposed around the cylinder sleeve or sleeves and a cylinder head mounted on the engine block, the coolant jacket is a separate component consisting of a material lighter than the normally used cast iron jacket and is firmly engaged between the crankcase and the cylinder head which is mounted onto the cylinder sleeve or sleeves.

  • Patent number: 6065439
    Abstract: 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.

  • Patent number: 6053142
    Abstract: 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.
