Abstract

PURPOSE:To increase the horsepower of an engine, produce at low cost and carry out an installing operation very simply by fixing an air compressing board having a plurality of tapered compressing holes to an inlet port part of an intake manifold. CONSTITUTION:A number of compressing holes 2 are bored in an air compressing board 1 within a range fitted for the inside wall forms of the foremost ends of ventilation pipes 5 so that the compressing holes 2 can be arranged in communicating hole parts between the ventilation pipes 5 and an intake manifold in the case of installing the board 1. Though each of the compressing holes 2 forms a taper shape so that the upper surface side can have a large diameter and the lower surface side can have a small diameter, the smallest diameter holes locate rather in the lower part than the middle part among the compressing holes so that the lower parts below the smallest diameter position are formed inversely in an expanded condition. In this way, complete combustion can be carried out by taking high density air into a cylinder so that an air compressing means can be simplified as much as possible at low cost and it can be also installed in various engines.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is an internal combustion engine such as a diesel engine or a gasoline engine. This relates to an air intake compression device for an internal combustion engine that promotes improvements in horsepower by inhaling the air in a concentrated state and completely combusting it in the cylinder (prior technology). This is a method of sucking air from the air and transferring it directly or via a supercharger or intercooler to the INTEC manifold to send a predetermined amount of air into the cylinder.Then, the air is highly compressed in the cylinder and heated to high temperature. Fuel is injected into the air and combustion occurs through natural ignition. Furthermore, air intake in a gasoline engine is almost the same, and fuel is injected midway through the engine to form a mixed gas, which is then fed into the cylinder. In addition, in various engines, engines equipped with a supercharger (turbo) are widely used to increase the amount of air supplied (intake amount) and improve horsepower, and also to adjust the amount of intake air at low speeds and high speeds. The engine is equipped with regulating valves and open/close valves that efficiently draw air into the cylinder to achieve complete combustion at each stage. Engines with reduced resistance and increased intake volume have been devised.

(Problem to be Solved by the Invention) However, conventional means for increasing the amount of intake air in various engines have focused on how to take in, or suck, a large amount of air. Developments have been made to increase the amount of intake air with the aim of increasing horsepower with engines of the same displacement. Therefore,
Increasing the amount of intake air according to the conventional concept increases the air volume in one cycle, which requires various devices and costs too much, making it more expensive than conventional engines. Ta.

The present invention has been made in view of the above points, and focuses on the fact that even if the volume is the same, if the air is high density, the amount of combustion air will be large, and the present invention draws high density air into the cylinder. To provide an intake air compression device for an internal combustion engine which achieves complete combustion by making the air compression means as simple as possible at low cost and can be installed in each engine.

(Means for Solving the Problems) The gist of the present invention to achieve the above object is to provide a tapered compression hole having a large diameter on the upper surface side and a small diameter on the lower surface side in an air compression substrate having an appropriate thickness. A large number of holes are formed in a range that matches the shape of the inner wall at the tip of the vent pipe communicating with the air cleaner, and the air compression board is fixed to the inlet part of the INTEC manifold, and each of the above-mentioned An intake air compression device for an internal combustion engine is characterized in that it is formed with a large number of compression holes.

(Function) As described above, in the intake air compression device of the present invention, the air sucked into the INTEC manifold from the air cleaner through the ventilation pipe is transferred to the taper of the air compression board fixed to the INTEC manifold intake port. Since a certain amount (constant volume) of air is compressed by each compression hole in the shape and enters the Intec manifold in an extremely dense state, even if the volume is the same as that inhaled under normal conditions, the actual combustion of oxygen, etc. Since it contains a lot of wood, it means that more air is inhaled, and it is possible to achieve complete combustion when the fuel is injected into the cylinder or when the mixture is ignited, and the thermal theory and actual horsepower are also considerable. This is something that can be improved. In particular, since the amount of intake air in a diesel engine is always constant,
When a large amount of air (molecules) is included within a certain amount of intake air, the combustion effect becomes extremely high. In addition, this device can be installed extremely easily by simply fixing a board with many compression holes in the inlet of the Intec manifold. Since it increases the amount of intake air, it is suitable for various engines, and can be easily installed if the shape is adapted to the intake manifold of various engines.

Furthermore, since this single device can increase horsepower sufficiently, it is possible to omit a separate supercharger, etc., and it is possible to provide users with an engine that provides sufficient acceleration at the start and is inexpensive. be.
