Abstract:
Carbon fibers heat-treated at 300 to 400 DEG C after being surface-treated with aromatic polysulfone resin, a heat-resistant resin composition having excellent mechanical strengths and comprising 5 to 50 wt % of said carbon fibers and 95 to 50 wt % of a heat-resistant resin, and parts for internal combustion engines produced using said resin composition, particularly impellers of integral-type-centrifugal compressor, are disclosed.
Abstract:
The present invention is directed to a snap-in mounting for mounting a top cover onto the engine of a motor vehicle, the top cover with the snap-in mounting, a mounting system with the snap-in mounting and a male part and a method of producing the snap-in mounting. The snap-in mounting for mounting a top cover onto the engine of a motor vehicle according to the invention comprises a female part including, a receiving part, which is adapted to receive the ball-shaped end of a male part by a snap-in connection, and a holding part for holding the receiving part, wherein the receiving part and the holding part are, preferably, separate parts, wherein the holding part is adapted to be fixed to the top cover's bottom side, which faces the engine of a motor vehicle when mounted, wherein the holding part, preferably, has a sliding portion, which is adapted to allow for a relative displacement of the receiving part and the holding part by a sliding motion, wherein the receiving part is moulded from a polymer material containing at least a thermoplast.
Abstract:
An engine with a hybrid crankcase includes the crankcase being a composite construction having an exoskeleton formed of a non-ferrite material having no defined endurance limit as a material, the non-ferrite exoskeleton encapsulating a load bearing skeleton formed of a ferrite material, the ferrite material having a well defined endurance limit, whereby the skeleton acts to carry the highest engine loadings. A method of forming such an engine is further included.

PCT No. PCT/DE96/01808 Sec. 371 Date Mar. 31, 1998 Sec. 102(e) Date Mar. 31, 1998 PCT Filed Sep. 20, 1996 PCT Pub. No. WO97/13597 PCT Pub. Date Apr. 17, 1997The aim is to improve the strength of an intermetallic bond between engine component made from an aluminium alloy and a reinforcing element made from austenitic cast iron. For that purpose, the reinforcing element is annealed in a decarbonising atmosphere before the known prior art alfin process is carried out, in order to obtain an alfin layer largely free of graphite scales.
Abstract:
The invention relates to Cu-based sintered alloy, which contains 10 to 40 % of Z, 0.3 to 6 % of Al, 0.03 to 1 % of oxygen and, as an additional element, either 0.1 to 5 % of at least one of Fe, Ni and Co or one of 0.1 to 5 % of Mn, 0.1 to 3 % of Si and 0.1 to 3 % of at least one of W and Mo, the balance being Cu and unavoidable impurities, and which has an excellent abrasion resistance in an atmosphere of room temperature to 400°C, a high strength, a high toughness, and excellent synchronization properties for a mating member as evaluated in terms of a friction coefficient. The invention also relates to the parts of automobile mechanisms formed of this alloy. Examples of the parts include synchronizing rings of a transmission, valve guides of an engine and bearings of a turbo charger.
