Abstract

PURPOSE:To improve an engine in its output and fuel consumption rate as well as its exhaust purifying performance, by securing a fuel injector in position through a proper number of holes formed in the upper side portions of cylinder to realize a circular combustion system, while simultaneously providing the upper part of cylinder with a precombustion chamber. CONSTITUTION:While a properly shaped circular combustion chamber 4 is provided at the upper side portion of cylinder 3, a properly shaped precombustion chamber 5 is provided at the upper part of cylinder 1. These two chambers 4, 5 are communicated via a passage to a main combustion chamber which is defined by the upper surface of piston 2, the interior surface of cylinder 3 and the lower surface of cylinder head 1. A proper number of catalyst devices 7 which are heated by energization is provided in the passage communicating with these two chambers 4, 5. A fuel injector 9 is provided in respective chambers 4, 5 and actuated properly in synchronization with the rotation of engine. The catalyst device 7 can burn unburnt substances in a fuel combustion gas injected and burnt in respective chambers 4, 5.

Description

[Detailed Description of the Invention] The feature of this invention is that the cylinder head of the engine (or the upper part of the piston is cut into an appropriate shape to create a space, and the side surface of the cylinder facing the space) is shaped into an appropriate shape. A swirling combustion chamber, a pre-combustion chamber, an injection-type combustion chamber, or any other suitable shape is provided by hollowing out the hole, and an appropriate number of catalyst devices of an appropriate shape are installed from the outside of each hole to at least a part of the inside. However, an energizing device is attached from the outside to one or more of the appropriate number of catalyst devices installed, and when the engine is started, the power is applied to heat the catalyst device, and then the switch is turned off, or the catalyst device is used while energized. Furthermore, a fuel injection device (and an ignition device may be installed if necessary) is installed at the back of the engine. The present invention relates to a high-output engine with extremely low fuel consumption and high combustion efficiency, which is characterized by the installation of a combustion device with a catalyst device in the form of (2).

Some conventional engines were equipped with a precombustion chamber or a swirling combustion chamber, but these were all designed for the sole purpose of precombustion, and even if explosive combustion was carried out in the combustion chamber, low-temperature combustion gas could not be dissipated. The engine was rotated by feeding completely burned fuel under the cylinder head, mixing it with newly supplied fuel, and exploding it again, but in any method, the engine was rotated in a high-pressure flame during one cycle. It has been considered technically impossible to completely burn the unburned substances contained in the fuel.

The features of the present invention are designed to eliminate these drawbacks, and to explain this based on one embodiment, this invention can be applied to the cylinder head (1) of an engine or the upper part of a piston (2). Create a space by cutting out at least a part of the cylinder (a catalyst device may also be installed in this space if necessary). A combustion chamber (4), a pre-combustion chamber (5), an injection type combustion chamber (6), or any other suitable shaped space is provided, and one or more suitable numbers are provided from the outside to at least a part of the inside of each hole. Catalyst device of appropriate shape (
7) and attach an external energizing device (8) to one or more of the appropriate number of catalyst devices installed, and when starting the engine, turn on the switch to heat the catalyst device (7) and then turn the switch on. Keep the power on until you turn off the power or stop the engine. The structure of the catalytic device is made of iron, tungsten, titanium, other metals, alloys, ceramics, etc., with a net shape, a honeycomb structure with an appropriate depth, or any other appropriate shape. Either cover the catalyst, or cover it with a heat-resistant material in advance and dry it well, then cover it with an appropriate catalyst and insert it between the items that make up the injection port of the combustion chamber, or screw or bolt. It can be used by attaching it with a bolt or nut, or using any other suitable method.

Furthermore, a fuel injector (9) is attached to the back of the injector (9), and fuel is injected from the injector (9) into the combustion chambers (4), (5), and (6) (this is exploded and combusted by fireworks from the spark plug). Do you want me to do it?
) When the fuel passes through an appropriate number of catalyst devices (7) that are instantaneously preheated one after another, the fuel explodes and burns, causing flames to flow through the catalyst devices (7).
7) While burning the unburned material contained in the flame, the gas compressed to high pressure under the cylinder head is injected directly onto the piston head which is being pushed up to top dead center. Then press down strongly on the piston head (2) to rotate the crank, or in the case of a gasoline engine, insert unburned fuel compressed at high pressure between the cylinder head (1) and the piston head (2). It is injected into the gas containing it in a flame state and mixes, causing an instantaneous re-explosion.
When the piston (2) is pushed down, another fuel injection device (10) is inserted into the gas compressed to high pressure between the cylinder head (1) and the piston head (2) in diesel engines. At the same time as new fuel is injected from the cylinder head ( 1) and the bottom of the piston (2)
) Each time the flame descends through an appropriate number of catalyst devices installed at a height above top dead center, the unburned fuel contained in the flame is repeatedly combusted. When it reaches the dead center and returns to the top dead center while rotating the crank, the flame that is pushed up passes through the catalyst device (7) while repeating combustion, and passes through the exhaust valve (11), the manifold, and the turbo on the way. In an engine, the turbine is rotated at high temperature and pressure, or in normal engines, the noise is passed through the exhaust pipe and the muffler, where it is muffled and released into the atmosphere, so the cause is from unburned substances contained in the exhaust gas. There will be no pollution at all. In addition, because the fuel is completely combusted to produce high output, gasoline engines require a smaller mixing ratio of fuel and air than before, and diesel engines reduce the amount of heavy oil injected at one time to the extent that the engine's combustion efficiency has increased. This is related to a high-output engine that is economical in that it can reduce fuel consumption, and by simply installing a catalyst device in the combustion chamber of an engine of the same type and specification as a conventional engine, the combustion efficiency of the engine will be greatly improved and the mileage will be dramatically increased. It is very beneficial to be able to drastically reduce fuel costs, and the contribution to the world economy is enormous.

The present invention is not limited to engines, but can also be applied to combustion gases in general.
