Abstract: The invention relates to an evaporator (1), in particular for an air-conditioning system of a motor vehicle, comprising flow channels for a coolant and ribs which can be impinged upon by air and which are arranged on the outside of the flow channels. According to the invention, at least one cooling element (5) which can be cross-flown by a coolant (5) is connected in a thermally conductive manner to the evaporator (1) and is connected to a secondary circuit (6) which acts as a cooler for the consumers, in particular electronic components (8).

Abstract: A cylinder head for an internal combustion engine with at least one pump/nozzle unit, including at least one bearing block with a bearing half for a camshaft and with a bearing half for a rocker arm shaft for at least one rocker arm for actuating the pump/nozzle unit, a first separate lubricant supply duct provided in the cylinder head, and a second lubricant supply duct provided in the bearing block, a first end of the second lubricant supply duct being connected to the first lubricant supply duct and a second end of the second lubricant supply duct ending open in a bearing face of the bearing half for the rocker arm shaft.

Abstract: A drive for pump-nozzle injection elements and injection pumps of an internal combustion engine. The drive includes a crankshaft, a camshaft for actuating the injection elements, and form-locking traction member for drivingly connecting the crankshaft to the to the camshaft so that torque angles change in a synchronous manner. The camshaft has cams which are optimized in each case for an injection process with respect to stroke velocity and thus feed rate of fuel. The cams are configured so that the torque angle or a range of torque angles (&agr;VHmax) before TDC of the cams at which the cams produce a maximum fuel feed rate deviates by an angle &agr;a from an optimum angle before TDC (K). An amount by which the angle deviates from the optimum angle in a direction toward TDC is no more than an angular error (&agr;F) resulting from an increase in length of the traction means during operation.
