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.

One configuration allows the top horizontal bar to be lowered down with two upright bars sliding towards each other, until the top horizontal bar completely folded on top of the two upright bars, reducing the physical volume of the truck rack. A second configuration is made up of two half-bars to form a straight top horizontal bar, secured by a bracket with two lug nuts. When the two half-bars are folded down in a lateral axial direction to the corresponding upright bars, they are then pivoted down in a longitudinal direction towards base pieces, resulting in wide open space of a truck bed for more versatile use.

A marine vessel advisory system can be configured to calculate and provide operational information showing fuel savings based on adjustments to the vessel's speed and / or heading. In one mode, the advisory system can operate in real time to gather information on operational and / or environmental conditions, which is then used to calculate alternative vessel operating performance that will save fuel and reduce emissions. The calculations may include simulation, machine learning, and / or artificial intelligence to determine a vessel speed and / or heading that will reduce fuel consumption. The advisory system can display the calculated information to the operator, who can then choose to switch to the alternative operating parameters (e.g., slower speed).In one mode, the advisory system can interact directly with a marine vessel system and automatically cause the marine vessel system to adjust operating parameters based on calculated operating parameters that save fuel and reduce emissions.
