"Internal combustion engine"

Conventional combustion engines usually burn hydrocarbons. For this purpose, fuel and oxygen are introduced into a combustion chamber. This combustion produces toxic exhaust gases that cannot be prevented but can only be reduced at great technical and financial expense. In addition, given the increasingly scarce reserves of fossil fuels, operating a combustion engine with such fuels is not desirable in the long term.

The innovation is based on the task of creating an internal combustion engine that can be operated without the use of petrol and that also produces exhaust gases that are as non-toxic as possible.

This problem underlying the innovation is solved by the features proposed in the claims.

In other words, an engine is proposed in which water is separated into oxygen and hydrogen using a laser beam and then caused to explode. The engine can also be operated with any other substance that does not require additional oxygen from outside for combustion, such as explosives.

An example of a new version of the

The internal combustion engine is explained using the drawing, which shows such an engine in section with some parts broken away.

In the drawing, '- generally referred to as an internal combustion engine, with a crankshaft 2, a connecting rod 3 and a piston 4. Above the displacement of the piston 4, a conventional poppet valve 5 is shown. Between the valve 5 and the uppermost region of the displacement of the piston Λ there is a combustion chamber 6.

The valve 5 is actuated purely by way of example via a camshaft 7, a push rod 8 and a rocker arm 9.

When the piston 4 moves upwards from its bottom dead center to its top dead center, the valve 5 opens the combustion chamber 6 so that after ignition and combustion, the exhaust gases are led out of the engine through an exhaust channel 10 during the upward movement of the piston 4. When the piston 4 has essentially reached its top dead center, the valve 5 closes and water is injected into the combustion chamber 6 using an injection nozzle 11. The water jet crosses a laser beam which is directed from an outlet 12 in the direction of the combustion chamber 6. A laser device from which the laser beam emerges is shown purely schematically and is designated 14.

At the high energy density of the laser beam, the water evaporates suddenly, with the desired temperatures being between 12,000° and 15,000 ⁰ C. At these temperatures, the water becomes

temperatures, oxyhydrogen gas is suddenly released, which explodes and drives the piston 4 downwards due to its expansion. During the subsequent upward movement of the piston 4, the valve 5 opens again and the burned gases can be discharged through the exhaust duct 10.

The new engine therefore works with at least one valve. Its working principle is, however, that of a two-stroke engine, since the piston only carries out one working stroke (with each downward movement) and one exhaust stroke (with each upward movement). The piston does not perform any intake or compression work, since the oxygen, which in conventional combustion engines is present in the form of outside air and must be sucked in and compressed, is bound in the injected water in the new engine.

In a modification of the embodiment shown, the engine can also be operated with a solid fuel instead of water. In this case, the water injection nozzle 11 is replaced by a corresponding feeding device for the solid fuel, whereby in such an embodiment it must again be ensured that the laser beam is directed at the solid fuel so that it is ignited by the laser pulse and evaporates suddenly.

In a modification of the embodiment shown, several valves 5 can also be provided in order to achieve a more effective exhaust gas flow. 35
