Abstract: The invention relates to a metallic cylinder head gasket for an internal combustion engine with sleeve, which comprises at least one metallic layer and has at least one combustion chamber opening and further openings, e.g. for fluids. By means of the cylinder head gasket according to the invention, a seal of a wet cylinder sleeve relative to the cooling water or combustion gases at the upper sleeve edge can be effected.

Abstract: A fuel metering pump (1) has a solenoid coil (2), an armature (3), a delivery piston (4) and spring-loaded valves. The spring-loaded valves are embodied as an electrically controlled suction valve (5) and an electrically controlled pressure valve (6). A solenoid coil (2) is provided for the armature (3) of the delivery piston (4), the armature (7) of the suction valve (5) and the armature of the pressure valve (6). The masses, springs and hydraulic cross-sections of the component parts are configured in such a way that the valves switch more quickly than the delivery piston moves.

Abstract: A heating system (1) is provided mounted in a motor vehicle with an internal combustion engine. The system (1) includes an additional heating system (2 or 3) or an auxiliary heating system (4). The additional heating system (2 or 3) or the auxiliary heating system (4), or a part thereof, is made in the shape of a modular component mounted on or connected to interfaces (I, II, III, IV) of the heating system which are specific for each vehicle. The modular component can optionally be replaced by another modular component of the same type.

Abstract: A motor vehicle heater arrangement is provided, the arrangement being connected to a vehicle. The vehicle heater arrangement includes a heater with a heater housing and with at least one of an engine coolant medium circuit connection and a motor vehicle interior space heating system heating medium connection defining a heating/cooling medium feed line connection and heating/cooling medium return line connection and with a fuel feed line connection. A water protection device is provided with the heater housing disposed therein. The heater and the water protection device are fastenable on an underside of the vehicle bottom. One of the heater housing and the water protection device has integrated securing points for securing to the vehicle floor.

Abstract: In an arrangement of a vehicle auxiliary heater with an integrated regulating device in the region of the floor in the vehicle cab and a control unit remote from the auxiliary heater, e.g. in the region of the dashboard or on an inner wall of the vehicle, it is proposed that the control unit be operationally connected to the regulation device wirelessly via a bidirectional radio link in which use is made of an r.f. unit with a first r.f. module on the operating side with a transmission and reception section and a second r.f. module on the control device side with a second transmission and a reception section. This obviates the need for the complicated laying of prior art wired connections between the control unit and the regulating device of the auxiliary vehicle heater, making the heater particularly suitable for subsequent fitting in commercial vehicles.
