  • Patent number: 9388763
    Abstract: In an internal combustion engine for a motor vehicle, having a cylinder housing in the form of a light metal alloy casting with working cylinder sections including cylinder liners which consist of rough-surface iron castings and which are integrally cast into the working cylinder sections with housing webs formed between adjacent liners, the cylinder housing has cooling channels formed in the housing webs between adjacent cylinder liners and the working cylinder sections of the cylinder housing for directly cooling the cylinder liners.

  • Publication number: 20140032041
    Abstract: The invention proceeds from an on-board diagnosis unit for a motor vehicle for detecting a released mechanical connection between at least two fluidic lines (10, 11), having at least one first contact element (12, 13, 14) and at least one second contact element (15) which is spaced apart axially, of which contact elements (12, 13, 14, 15) at least one is provided for being deformed at least substantially elastically for making contact with at least one connecting point (16, 17, 18) of the mechanical connection. It is proposed that the on-board diagnosis unit has at least one third contact element (12, 13, 14) which is arranged spaced apart axially from the second contact element (15).

  • Publication number: 20130306007
    Abstract: In a device for providing clean combustion air for an internal combustion engine of a working tool, provision is made for a cyclone filter into which ambient air contaminated with impurities can be sucked. A partial air flow contaminated with impurities can be extracted by suction from the cyclone filter, a partial air flow substantially freed from impurities is branched off from the cyclone filter and supplied to the internal combustion engine as combustion air. A fan which provides a flow of cooling air against the internal combustion engine, is at least partially accommodated in a housing. Provision is made in the housing for at least one suction bore, which leads into the housing and provision is made in the area of the suction bore for a flow element for creating a low pressure. The partial air flow contaminated with impurities is connected to the suction bore.
