Abstract

A flow-through internal combustion engine comprising an arrangement for compressing air, a combustion chamber with a fuel injection arrangement and optionally an arrangement for water injection, and an arrangement for expanding exhaust gas, wherein the expansion arrangement (4) is constituted by a piston arrangement, especially of the type that produces reciprocal motion or rotational motion, and the flow of air and exhaust gas through the combustion chamber (2) is unidirectional. In an alternative solution the air compressing arrangement (1) and the expanding arrangement (4) are constituted by the same piston arrangement, especially one of the type that produces reciprocal motion or rotational motion, and the flow of air and exhaust gas through the combustion chamber is also unidirectional.

Description

Flow-through internal combustion engine The object of the present invention is a flow-through internal combustion engine. There is a well-known flow-through internal combustion engine, which consists of a compressor, a combustion chamber as well as an expansion arrangement in the form of a turbine, wherein the combustion chamber is placed between the compressor and the expansion arrangement. In the known engine the air is compressed in the compressor, then it flows to the combustion chamber, where fuel is ignited and the exhaust gas formed flows to the expansion arrangement, where the energy of expanding exhaust gas is transformed into mechanical work. Also well known are piston engines including a piston-cylinder arrangement. In these engines the fuel mixture is compressed and ignited by an electric spark, like in the Otto engine, or air is compressed and fuel is injected, causing ignition, like in the Diesel engine. The flow-through internal combustion engine according to the invention, comprising a combustion chamber with a fuel injection arrangement and optionally with an arrangement for water injection, an arrangement for compressing the air and an arrangement for expanding the exhaust gas, is characterized in that the arrangement for expanding the exhaust gas is a piston arrangement, especially one that produces reciprocal motion or rotational motion, and the flow of air and exhaust gas through the combustion chamber is unidirectional. ln an alternative solution the air compressing arrangement and the arrangement for expanding the exhaust gas constitute the same piston arrangement, especially of the type that produces reciprocal motion or rotational motion, and the flow of air and exhaust gas through the combustion chamber is unidirectional. The advantage of the flow-through engine is the possibility of burning any fuel mixture irrespective of its leanness, as well as the possibility of burning, without any major difficulties, any type of liquid or gaseous fuel, ranging from heating oil to hydrogen. The engine can also be applied in cogenerative arrangements as well as an automobile engine. The engine according to the invention is extremely flexible and its characteristics resemble those of a steam engine. The object of the present invention is shown in a drawing representing a schematic view of a flow-through internal combustion engine, as an example of possible embodiments of the invention, which is not meant to limit the scope of the present invention. The engine comprises a combustion chamber 2 with an injection arrangement 3, placed between a compressor 1 and an expansion arrangement 4, which constitutes a piston arrangement of reciprocal motion. Air is compressed in the compressor 1 and flows through a passageway to the combustion chamber 2, where the fuel is injected and the fuel-and-air mixture is ignited. The exhaust gas from the combustion chamber 2 flows through passageway to the piston arrangement 4, where it undergoes expansion and the energy of expanding exhaust gas is transformed into mechanical work. The flow of exhaust gas is controlled by an arrangement of valves. ln the flow through engine it is essential that the operations of compression and expansion be separated to enable almost continuous, unidirectional flow of air and exhaust gas through the combustion chamber 2. Injecting water into the combustion chamber 2 and/or into the working space of the cylinder improves the efficiency of the engine when compared to well- known traditional engines.
