  • Cylinder block of an internal-combustion engine
    Patent number: 5842447
    Abstract: A cylinder block of an internal-combustion engine of an open-deck construction, in which the cooling water jacket and the oil jacket between the cylinder tube and the cylinder block housing are separated from one another by a connection web which connects the respective cylinder tubes with the cylinder block housing. In order to reduce the cylinder tube distortions in the braced condition of the cylinder block, ribs are provided at least in the water jacket or in the oil jacket. The ribs start out from the connection web and improve the linking of the cylinder tubes to the cylinder block housing. The height of these ribs is much lower than the height of the water jacket or of the oil jacket which results in a low weight increase and minimizes the linking lengths to the cylinder tube.

  • Cylinder head threaded connection arrangement
    Patent number: 5463991
    Abstract: An annular gap formed between a shaft of a cylinder head bolt and adjacent components is filled with a wire knit for example to increase the heat transfer. The improved heat transfer reduces the increase in bolt force, especially after a cold start of the internal combustion engine.
