Kraftfahrzeug mit Brennkraftmaschine und Verfahren zum Betreiben einer Brennkraftmaschine

Liquid-cooled generator

Internal combustion engine with cylinder head has transverse coolant flow, second accommodation shaft for glow plug between inlet channels at least partly enclosed by coolant chamber

Internal combustion engine e.g. diesel or petrol engine, for motor vehicle, has additional compressor that is provided downstream or upstream of compressor of turbocharger, bypassed over bypass, and propelled by centrifugal mass

Connecting rod for an I.C. engine comprises connecting rod eyes having a cross-section which deviates from a circular or cylindrical shape

Operating method for a heat-exchanger device in a motor vehicle with an internal combustion engine integrates an oil cooler and an exhaust-gas return cooler in a heat-exchange structure

Internal liquid-cooled combustion motor has an intermediate coolant zone, in the section between cylinders, and a corresponding zone in the cylinder head with a link through an opening in the gasket

Fabrication method of a casted cylinder head

Crankshaft for e.g. V-engine, has recesses overlapping with base area, of side walls, adjacent to base and hub pivots in radial direction, where recesses are provided directly adjacent to load area of pivots

Prefabricated molded blank of an annular or hollow cylindrical component used as a housing in a reciprocating piston machine has temperature-dependent layers which are varied and optimized using a bimetal effect
