Embodiment Construction

[0032] figure 1 A piston machine 1 according to a first exemplary embodiment of the invention is shown schematically. The piston machine 1 is driven by a steam process. The piston machine 1 can be used here in particular in an internal combustion engine of a motor vehicle in order to utilize the waste heat of the internal combustion engine. The piston machine 1 then converts the waste heat into mechanical energy, which can be used, for example, as additional drive energy or to drive auxiliary units, in particular a generator. However, the piston machine 1 according to the invention is also suitable for other applications.

[0033] The piston machine 1 has a housing part 2 and a cylinder 3 connected to the housing part 2 . In this exemplary embodiment, the piston machine 1 has exactly one cylinder 3 .

[0034] The cylinder 3 of the piston machine 1 has a cylinder bore 4 in which a cylinder piston 5 is arranged. The cylinder piston 5 is here displaceably arranged in the cyl...

Abstract

A piston engine (1) that can be driven using a steam power process and is used in particular for utilizing waste heat from an internal combustion engine comprises at least one cylinder bore (4), a cylinder piston (5) which is arranged in the cylinder bore (4), and a rod (20) which is connected to the cylinder piston (5). The rod (20) is guided out of the cylinder bore (4). The cylinder piston (5) delimits a first operating space (9) and a second operating space (10) in the cylinder bore (4). A crankshaft (22) is disposed in a crankshaft space (21). The rod (20) is connected to a slider crank mechanism (23) which is disposed in the crankshaft space (21), the rod (20) being effectively connected to the crankshaft (22) via the slider crank mechanism (23), thus making it possible to obtain a large expansion volume while keeping the design of the piston engine (1) compact.

Description

technical field [0001] The invention relates to a piston machine that can be driven by a steam process. The invention relates in particular to a piston machine which can be driven by a steam process and which is used to utilize the waste heat of an internal combustion engine. Background technique [0002] Internal combustion engines convert fuel energy into mechanical energy to drive motor vehicles and the like. However, a large part of the energy is thereby released as waste heat which is carried off from the internal combustion engine via the cooling system or in the exhaust gas. In order to utilize this thermal energy, it is conceivable to couple the steam power process with an internal combustion engine. The thermal energy from the internal combustion engine can thus be used to generate steam, which is decompressed in the expander and thus provides additional energy that can be used to drive the motor vehicle or to generate auxiliary energy. Here, however, the problem...
