Abstract

PURPOSE:To improve combustion efficiency and to allow an engine to exhibit its output to the maximum possible extent with a little fuel by fixing a suitable number of catalyzer device in a suitable form to the tip end of a combustion injection nozzle or to the inside of an intake opening or an exhaust opening in a cylinder of the engine. CONSTITUTION:A suitable number catalyzer device 5 with a suitable from and size are provided on the tip end of a combustion injection nozzle 2 or the intake opening 3 or the exhaust opening 4 in an engine cylinder 1. When fuel is injected into the cylinder 1 from the injection nozzle 2 and expoded, gaseous body which includes pre-combustion fuel and passes through the catalyzer 5 in a moment is given full combustion to the included pre-combustion material during the time it passes through the catalyzer 5 forward and backward. Therefore, combustion temperature is extremely increased and combustion efficiency is improved. Consequently, fuel is injected with less mixing ratio of fuel against air than the conventional ratio and it is given full combustion, allowing an engine to exhibit its output to the maximum extent, thereby an engine with high combustion efficiency can be obtained.

Description

[Detailed Description of the Invention] This invention involves installing an appropriate number of catalyst devices in an appropriate shape at the end of a fuel injection nozzle in a cylinder, inside an intake or exhaust port, or at an appropriate location, and injecting the fuel into the cylinder from the nozzle. Each time the injected fuel ignites and explodes and passes through the catalytic converter (one way or round trip), the unburned fuel is completely combusted, the combustion temperature is increased, combustion efficiency is increased, and the output of the engine is increased using a small amount of fuel. This relates to a high-output engine with high combustion efficiency, which is characterized by maximizing the combustion efficiency.

Conventional diesel, gasoline, motorcycle, and other engines have low combustion efficiencies, and their exhaust contains large amounts of unburned substances that are released into the atmosphere, causing exhaust gas pollution.

The present invention has been devised to eliminate these drawbacks, and to explain this based on one embodiment, the tip of the fuel injection nozzle (2) in the cylinder (1) of an engine, the intake port (3), etc. Exhaust port (4)
A suitable number and size of catalyst devices (5
) is equipped with an injection nozzle (2
) when fuel is injected into the cylinder (1) and exploded, the gas containing unburned fuel that instantly passes through the catalyst device (5) is also included while passing through the reciprocating catalyst device (5). It has the effect of completely combusting unburned substances, significantly increasing the combustion temperature, and increasing combustion efficiency, so compared to conventional methods, the mixture ratio of fuel to air is lowered and the fuel is injected to achieve complete combustion, thereby increasing engine output. It is possible to create a high output engine with high combustion efficiency, which is characterized by maximum performance.

In a diesel engine, even if the catalyst device is installed inside the cylinder, it can be used from the beginning in the same way as a conventional engine, and in addition, the high-pressure gas that explodes each time it moves up and down inside the catalyst device (5) installed inside the cylinder (1). It is possible to completely burn the unburned substances contained in the engine, raise the combustion temperature, and maximize the engine's output, so it is sufficiently effective even if the mixing ratio of fuel to air is significantly lower than before. It is convenient because it eliminates the black smoke emitted into the air during incomplete combustion, which is characteristic of diesel engines.

In addition, in gasoline engines and engines that use alcohol or other gases as fuel, even if a catalyst device is installed in the cylinder, the catalyst device is heated by either igniting it from beginning to end with a spark plug as before, or by igniting and detonating it with the spark plug first. After that, turn off the spark plug, and then directly inject fuel into the catalyst device and ignite it, or directly inject fuel into the catalyst device and ignite it without using a spark plug from the beginning. Alternatively, the catalyst device may be heated in advance by heating or by other methods, and then the fuel may be directly injected into the catalyst device (5) and ignited, and then the fuel may be ignited in the catalyst device (5) and unburned materials may be completely combusted. It can be used as an engine that performs the same continuous ignition role as a hot-pot engine and does not require a spark plug.

In addition, this engine has the feature that it can be used with gasoline, heavy oil, water, propane, various mixed gases, alcohol, and other volatile fuels by reducing the mixing ratio of fuel with air. This is very convenient because it can contribute to energy saving by increasing combustion efficiency and increasing engine output by reducing the size of the engine.

In addition, since the combustion efficiency of the engine improves and the temperature rises, the heat-resistant structure can be sufficiently resistant by using a ceramic engine or by exposing heat-resistant materials in appropriate places. Furthermore, the catalytic device (5) is also a ceramic mesh or honeycomb structure, iron, titanium, tungsten wire mesh, honeycomb structure, or other structure, directly or once a heat-resistant material is exposed and a platinum catalyst and/or other catalyst is applied thereon. In the cylinder (1
) Attach an appropriate number of them to the appropriate locations.

By passing the exhaust gas through the catalytic device again during exhaust, it is completely combusted, and when the exhaust gas is released into the atmosphere through the muffler, unburned substances are almost completely eliminated, and pollution caused by unburned substances can be prevented. . Also, combustion efficiency has improved 1
When the temperature reaches around 200 degrees Celsius, some of the water vaporizes and decomposes into water and burns, so when injecting fuel into the cylinder (1), a small amount of water is made into a mist and injected together with the fuel. Some of the harmful substances emitted from the exhaust gas can be destroyed by burning them, or water droplets can be dropped from the engine to the muffler at appropriate intervals at appropriate intervals to generate water vapor by the exhaust heat of the high-temperature exhaust gas. It is also possible to prevent pollutants from dispersing into the atmosphere by making them mixed into exhaust gas and trapping them by adsorbing them to water vapor.

In addition, by increasing the combustion efficiency and increasing the output of the engine, and making the engine smaller accordingly, it becomes economically cheaper and can also contribute to energy saving, which is very convenient.
