Abstract: A piston for an internal combustion engine, having a piston base body, a piston ring element having at least an inner region of a piston crown, and a piston skirt. The piston is provided with pin bosses having pin bores and the ring element has at least an outer region of a piston crown having a circumferential top land and a circumferential ring belt provided with ring grooves. The piston base body and piston ring element are joined together by way of corresponding, conical joining surfaces configured on them.

Abstract: A piston for an internal combustion engine has a lower piston part and an upper piston part disposed on the lower piston part. The upper piston part has a top land that runs around its circumference, and a ring belt that runs around its circumference. At least the upper piston part consists of a sintered material.

Abstract: The present invention relates to a piston (10, 110, 210) for an internal combustion engine, having a piston base body (11, 111, 211) and a piston ring element (12, 112, 212), whereby the piston base body (11, 111, 211) has at least an inner region (14) of a piston crown (13) as well as a piston skirt (16), which is provided with pin bosses (18) having pin bores (17), whereby the piston ring element (12, 112, 212) has at least an outer region (21) of a piston crown (13) having a circumferential top land (22), and a circumferential ring belt (23) provided with ring grooves (24). According to the invention, it is provided that piston base body (11, 111, 211) and piston ring element (12, 112, 212) are joined together by way of corresponding, conical joining surfaces (32, 33, 27, 28; 135, 136; 232, 233, 227, 228) configured on them. The present invention furthermore relates to a method for the production of such a piston.

Abstract: The invention relates to a heat exchanger assembly, in particular a radiator assembly for the front section of a motor vehicle, including a heat exchanger. The heat exchanger is configured in several parts in the form of heat exchanger elements, i.e. at least one primary heat exchanger and at least one secondary heat exchanger, and at least two of the heat exchanger elements can be displaced in relation to one another in the event of a crash.

Abstract: The invention relates to a heat exchanger assembly (1), in particular a radiator assembly for the front section of a motor vehicle, comprising a heat exchanger (2, 3). According to the invention, the heat exchanger (2, 3) is configured in several parts in the form of heat exchanger elements, i.e. at least one primary heat exchanger (2) and at least one secondary heat exchanger (3), and at least two of the heat exchanger elements can be displaced in relation to one another in the event of a crash.

Abstract: The invention relates to a coolant circuit for a motor vehicle having an engine and a radiator. The coolant circuit includes an exhaust gas heat exchanger and enables engine coolant coming from the radiator to be supplied directly to the exhaust gas heat exchanger. In a preferred embodiment, coolant coming from the radiator and/or from the engine can be selectively supplied to the exhaust gas heat exchanger via a changeover device.

Abstract: A system that includes a set components that can offer a complete solution to a client or can be partitioned to offer solutions to specific areas. The components are modular. The components are independent and integrated containing all the necessary processes and inputs and outputs to function independently. The components can also be. integrated together into a system where the components work together. The set of components are also convergent by allowing all services to be provided and viewed via single interface through a single consolidated customer database independent of the type of service(s) being provided to a customer.
