Abstract

The invention is called "Cutting Blade", which is a device installed in the engine intake pipe. Through friction, cutting, and heat transfer, it combines the air entering the engine with atomized fuel to form a high-quality mixture, enabling more energy to be released during the explosion and power stroke, and the mixture to burn more completely, achieving the purpose of fuel savings and exhaust gas reduction. Its core principle is to cut, refine, and uniformly heat the air entering the engine. The dominant thinking in the product design and structure is to not only cut the air flowing through the intake pipe but also minimize the resistance of this device to hinder the air from entering the engine. Practice has proven that installing this device can effectively reduce the phenomenon of altitude sickness in vehicles. The technical field to which the invention belongs is: automotive power efficiency, automotive exhaust gas reduction, and technologies for dealing with automotive altitude sickness. The inventor solved the problem of abnormal noise generated by previous similar products during high-speed driving through ingenious design. The result was obtained through a total of six design modifications during the actual test of 90,000 kilometers in seven years.

[0001] Automobile engine efficiency, reduction of automobile exhaust emissions, and technologies for dealing with automobile altitude sickness. Background Art

[0002] "How to Drive to Save Fuel", published by Sichuan Science and Technology Publishing House and written by Xiong Yunhaoye, describes on page 213: An automotive vortex supercharger is a device designed based on the principles of gas dynamics. By changing the intake direction and pressure through blades, it generates an air vortex, increasing the engine intake volume at medium and low speeds, making the fuel and air mixture more complete, and improving the combustion condition of the engine at medium and low loads. The product is made of stainless steel, not easily damaged, with a simple structure and reliable operation. Additionally, this device with patent numbers ZL201520210188.2, ZL201530052352.7, and ZL201530092532.8 has a defect: when the vehicle accelerates to 85 km / h (or above), it emits continuous "clang clang" abnormal noises because of a problem in the product design, which obstructs the intake of the intake duct when the engine is running at high speed. The present invention solves this problem, with the engine having no abnormal noises and strong power. Summary of the Invention

[0003] The core design of the blade is that the entire product is covered with serrated and bladed knives, more precisely, knives in the shape of the letter "V". Such a design forces the flowing air to rotate and roll, and the air molecules are cut into discrete pieces. Imagine this is like the scene of humans or animals eating. First, the food is torn and mashed with teeth, and then swallowed into the stomach. The purpose of this design is to make the atomized fuel fully mix with the shredded air, making an excellent and sufficient preparation for the next compression stroke of the piston. Finally, greater energy is generated during the explosion stroke in the cylinder, achieving the effects of increasing power, reducing fuel consumption, and reducing exhaust emissions. Through actual road tests in the high-altitude area (4600 - 5100 meters) of National Highway 318, it is confirmed that installing the blade can effectively reduce the phenomenon of automobile altitude sickness, and the automobile altitude sickness is not obvious.

[0004] The air intake manifold consists of a cylindrical tube and three V-shaped guide vanes, made of 316 stainless steel. Two air intake manifolds are installed on the intake system of gasoline-powered vehicles (or vehicles that require air intake as part of the air-fuel mixture). One is installed at the outlet of the air filter (called air intake manifold 1), and the other is installed at the inlet of the throttle body (called air intake manifold 2), with half of the air intake manifold entering the throttle body and the other half exposed. When the engine is running, outside air enters the air filter through the intake manifold, then flows through air intake manifold 1, then through air intake manifold 2, and finally into the throttle body. Through heat transfer and the action of the bladed V-shaped serrations and prismatic holes, the air molecules are broken up and evenly heated. (The heat from the throttle body heats air intake manifold 2 through heat transfer, and the air flowing through air intake manifold 2 receives heat evenly from it.) The friction between the air and the entire air intake manifold 2 also generates heat. This process helps to fully mix the air with the atomized fuel. The design and structure of the sword were meticulously crafted by the inventor, who also created and installed the actual sword on a car for road testing. Hundreds of sets of data were collected during the seven-year, 90,000-kilometer experiment, and the design was revised six times.

[0005] The vehicle used in the experiment was a 2012 GAC Toyota Camry Hybrid. To ensure the accuracy of the experiment, refueling was always done at the same Sinopec gas station. Before refueling, photos were taken of the instrument panel to record the current fuel consumption, mileage, total odometer reading, mileage driven on the current tank, and remaining range. The odometer's trip counter was then reset to zero. Before refueling, the gas station attendant was reminded to add 92-octane gasoline until the pump clicked off for the first time. The vehicle was then driven until the low fuel warning light illuminated, and the mileage and other data were recorded. Subsequent refueling was also conducted at the same gas station and using the same pump number whenever possible. This method can effectively calculate the actual fuel consumption per tank, even at any point along the route, allowing for the calculation of fuel consumption per 100 kilometers for that segment of the journey.

[0006] As we know from the use of air filters, after a car has driven several hundred kilometers, fuel economy gradually decreases due to the accumulation of fine dust in the filter element, meaning fuel consumption increases. However, this gradual increase is so slow that it's difficult for the driver to notice. Analysis of dozens of fuel consumption data points shows that since blocked air intake increases fuel consumption, the blades installed in the intake manifold also block air intake, as this component occupies a certain cross-sectional area of ​​the intake manifold. How can we reduce the obstruction to air entering the engine? The answer is to thin the blades and outer shell, making them as sharp as a knife edge! The blades gradually transition from the thinnest edge to all parts of the blade. The blades guide and change the direction of the airflow, but more importantly, they cut the air and ensure even heating. The cylindrical outer shell serves as the support for the blades. The entire blade occupies a certain cross-sectional area of ​​the intake pipe. Without polishing, once the vehicle speed exceeds 85 kilometers per hour and the engine rapidly draws in air, these blades will obstruct the airflow, causing the driver to hear a continuous "clanging" noise. By polishing the outer shell and blades, and drilling holes in the blades (prism-shaped holes with polished edges), the blade edges are made into a "V" shape. This solves the noise problem at high speeds. This process was learned through use, followed by in-depth research and practical testing, leading to the solution.

[0007] The air filter cutter is made of 316 stainless steel sheet, 0.5 mm thick. A car typically has two air filter cutters installed. Generally, air filter cutter 1 (installed at the air filter outlet) is larger than air filter cutter 2 (installed at the throttle body inlet). The air filter cutter consists of a cylindrical outer shell and three "V"-shaped blades. Each blade has four "feet" that are embedded in slots on the inner wall of the cylindrical outer shell. These are securely fixed to the inner wall using laser welding. The three blades are evenly arranged and welded. The cylindrical outer shell has a notch, occupying approximately one-sixth of the total area. This is because the cylindrical outer shell only serves as a support for the blades; removing this notch reduces obstruction to air entering the engine. Each blade has six prismatic holes, the edges of which are ground to a blade shape. The acute angles of the holes are sharpened with a fine round file to create a blade-like edge. The blade edges are cut into continuous "V" shapes at approximately a 60-degree angle, also ground to a blade-like shape. Looking into the cylinder from the circumference, which is the direction of air intake, each blade has a "U"-shaped (or "V"-shaped) groove near its center, which is the windward groove and is also ground to a blade-like shape. Because the throttle body size may vary from car to car, the blades may have different prismatic holes of different sizes, and the number of holes on each side may differ, perhaps three or four. This design aims to minimize air resistance.

[0008] The "V"-shaped blade at the air inlet of the cylindrical shell of Blade 1 should be ground from the inner wall, only on one side, and the air outlet should be made in the same way. The "V"-shaped blade at the air inlet of the cylindrical shell of Blade 2 should be ground from the inner wall only, and the air outlet should be ground from the outer wall only. The size of the blades should be determined according to the size of the throttle body inlet and the air filter outlet. Ideally, Blade 1 should fit snugly against the circular inner wall of the air filter outlet after installation, while Blade 2 should fit snugly against the circular inner wall of the throttle body inlet. Generally, Blade 2's shell has three small limiting steel plates bent at right angles to ensure that the shell only extends halfway into the throttle body and does not shift. When installing Blade 2, the notch on the shell should face the throttle body's flip-up flap towards the cylinder, while the notch on Blade 1's shell should face the opposite side of the air flow meter.
