摘要： A piston and a reciprocating expansion engine with a piston having a piston head, a piston neck, and a piston shaft are described. The piston head has at least one groove which runs in a circumferential direction suitable for receiving a piston ring, and the piston shaft has a pin boss and, at its outer circumference, a guide surface which is suitable for guiding the piston along a cylinder inner wall. An outer diameter of the piston neck is smaller than an outer diameter of the piston head and/or of the piston shaft, and the length of the piston neck approximately corresponds to the travel of the piston in the installed state.

The drive unit has an internal combustion engine in operative connection with a driven shaft and a reciprocating piston expansion engine in an operative connection with a crankshaft. The driven shaft is mechanically connected to the crankshaft by a clutch in such a way that torque is transmitted from the crankshaft to the driveshaft. The reciprocating piston expansion engine has at least one cylinder, and a fluid is guided from a fluid supply into an interior of the at least one cylinder at least occasionally via an inlet valve and a bypass valve which is arranged in parallel with the inlet valve.

摘要： A cooling circuit and an independent heat recovery circuit are associated with an internal combustion engine. A coolant is circulated a pump in a first and a second cooling sub-circuit. An increase in pressure in a work medium is achieved within the heat recovery circuit by a pump. This work medium is changed from liquid aggregate state to vaporous aggregate state and back to the liquid aggregate state in heat exchangers. This work medium is divided after the pump into two parallel partial flows and is changed into vaporous state in a first parallel branch in an EGR heat exchanger through which recycle exhaust gas flows and in a second parallel branch in an exhaust gas heat exchanger through flow exhaust gas downstream of the low-pressure turbine flows. This vaporous work medium is then fed to an expander and is then conducted through a cooled condenser and, liquefied again.

摘要： A method and a device for controlling the engine braking operation in internal combustion engines for motor vehicles, wherein the internal combustion engine is operated with direct injection of fuel and a controllable brake flap is provided in the exhaust gas system for retaining exhaust gases in the engine braking operation, and moreover has an exhaust gas recirculation device having an EGR valve that is arranged upstream of the brake flap and a recirculation line that connects the exhaust gas system to the intake system of the internal combustion engine and during the driving operation controls a defined quantity of recirculated exhaust gas with respect to the combustion air. To avoid critical excessive temperatures at the injection valves, in the engine braking operation (MB), the EGR valve (13) is more or less opened in dependence upon operating parameters (n, TE) of the internal combustion engine (1).
