ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to a hydraulic air-intake governor for connecting to a rear part of a throttle valve in an engine system of a car in order to regulate the supply of air to the engine system for mixing with fuel in the engine.
(b) Description of the Prior Art
In most general engine systems, fuel and air are mixed to provide fuel air mixture that is ignited to produce gas explosion in the engine, so that a pressure produced by the gas explosion pushes a piston in the engine to generate a driving power.
To maintain a predetermined gas explosive pressure, it is necessary to effectively control the amount of air and fuel guided into the above described engine system. An exceeded air intake while the engine is not in a vacuum state will result in serious single-cylinder effect to cause vibrating car body and unstable engine revolving speed that would have adverse influence on the smooth operation of the engine, particularly when the engine is first started.
It is therefore desirable to develop a means to eliminate the drawbacks existing in the conventional engine systems.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a hydraulic air-intake governor that can be externally connected to the engine system by installing the air-intake governor in the trunk of the car, for example, without occupying any space in the engine system, and that is capable of straining air and regulating air amount that can be supplied to and sucked into the engine.
To achieve the above and other objects, the present invention provides a hydraulic air-intake governor that is indirectly connected to a rear part of a throttle valve of the engine system.
The hydraulic air-intake governor mainly includes a container being provided at a head portion with a capped water hole via which water is filled into the container for the same to always maintain a predetermined amount of water therein, an air inlet pipe for guiding external air to a bottom portion of the container, and an air outlet pipe for guiding air moved from the bottom portion to the head portion of the container to move out of the container.
Multiple vertical supports support three horizontal steel partitions in the container, namely, upper, middle, and lower steel partitions. The partitions being provided with holes via which air guided to the bottom portion of the container moves upward to the head portion.
Two buoys having a specific gravity close to that of water separately float on the water in the container between the upper and the middle steel partitions and between the middle and the lower steel partitions. The buoys have a bottom surface of a predetermined area large enough for closing some of the holes on the middle and the lower steel partitions.
A water level gage is connected to and vertically extends in parallel with the container for observation of a water level in the container at any time in order to timely replenish the container with water.
A vapor/air separator is connected to the air outlet pipe extended from the container for sucking vapor and extra air out of the container.
An air-supply regulator is connected downstream to the vapor/air separator with an end thereof indirectly connected to an output end of the vapor/air separator and the other end to an input end of an engine in the engine system. The air-supply regulator includes a substantially tubular body, an air-intake branch pipe provided at a lower end of the tubular body with a beveled upper end extended into the tubular body, an air-exit branch pipe connected to an upper end of the tubular body with a flat lower end thereof extended into the tubular body, and a ball disposed in the tubular body between the beveled upper end of the air-intake branch pipe and the flat lower end of the air-exit branch pipe. Whereby when the engine sucks a large volume of air, the ball is sucked upward to loosely block the flat lower end of the air-exit branch pipe and therefore reduces air supplied to the engine via the air-exit branch pipe; and when the engine sucks a small volume of air, the ball drops to locate above the air-intake branch pipe without blocking the beveled upper end of the air-intake branch pipe to cause any decrease of air flowing into the air-supply regulator via the air-intake branch pipe.
When air is guided to a lower part of the container, which is in a vacuum state, and moves upward to pass through the water in the container, the air is strained and cooled to have a compressed and increased density. The cooled and high-density air will reduce air temperature in the engine for the same to generate increased horsepower.
The buoys selectively close some of the holes provided on the middle and the lower partitions depending on the water level in the container and accordingly control passages in the container available for the air to move upward, so that air that can be supplied to the engine is always maintained at a fixed amount. Since the engine can always have a fixed air amount supplied to it by externally connecting the hydraulic air-intake governor to it, the problems of single-cylinder effect, vibrating car body and unstable revolving speed of engine that would otherwise occur in the conventional engine when the same has exceeded air intake could therefore be eliminated. On the other hand, drawbacks such as air pollution caused by exhaust gas and knocking caused by internally carbon-deposited engine due to insufficient air intake and accordingly incomplete combustion could therefore be eliminated. By observing the water level gage, insufficient water amount in the container can be found earlier to timely replenish the container with water and maintain the normal operation thereof.
Moreover, the hydraulic air-intake governor of the present invention can be indirectly connected to a negative-pressure-intake branch pipe at the rear part of the throttle valve to supplement insufficient air originally supplied to the engine via an engine positive-pressure-intake pipe.
With the air-supply regulator, the ball disposed therein would be sucked upward to block the air supplied to the engine from the present invention when the engine has a large air intake, and the ball would drop to admit air supply to the engine from the present invention when the engine has an insufficient air intake. Therefore, gas explosion in the engine due to exceeded air intake of the engine can be avoided.
The hydraulic air-intake governor of the present invention could be mounted in the trunk of a car through extended connecting hose and would not occupy any space in the original engine system. Air guided to the engine from the hydraulic air-intake governor mounted in the trunk would not be contaminated by exhaust gas and dust to secure the supply of quality air to the engine.
The hydraulic air-intake governor of the present invention can be externally connected to all types of existing engine systems at any time and is therefore not necessary to present in the form of a standard equipment in a new car. Since the present invention employs only a simple water container to control and regulate the amount of air supplied to the engine, it can be manufactured at low cost while produces high economical effect.
The water level gage has a lower end that extends into said container and has an upward extended water inlet pipe connected thereto, so that water in the container would not be completely sucked into the water level gage for the container to keep a desired minimum water level and a compressed vacuum state therein.
The vapor/air separator has a storage cylinder connected thereto for storing vapor and extra air supplied by the container. In the event the engine has insufficient air intake, air stored in the storage cylinder can be duly supplied to the engine in order to increase the revolving speed of the engine. The storage cylinder also prevents improperly large amount of air from entering the engine chamber to avoid extreme explosion or burning in the engine and unnecessary waste and high cons
