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.

The fuel pump assembly fuel supply module comprises a flange plate, a fuel outlet pipe and a control assembly, the fuel outlet pipe comprises a fuel outlet nozzle connector and a fuel outlet through pipe, a fixing block is arranged on the side wall of the fuel outlet through pipe, a fixing cavity is formed in the middle of the fixing block, and a pressure transmitting opening communicated with the fuel outlet through pipe is formed in the bottom of the fixing cavity. And an oil pressure sensor penetrates through the fixed cavity. The oil pressure sensor can accurately detect the fuel oil pressure in the oil outlet pipe and feed back a pressure signal to the control assembly, and the control assembly identifies the pressure signal and adjusts the rotating speed of a pump core of the fuel oil pump in real time according to the pressure value, so that the oil pumping efficiency of the fuel oil pump is controlled, and on-demand oil supply of the fuel oil pump assembly is achieved. Compared with the mode that the flow sensor is arranged in the oil tank, the oil pressure sensor is arranged on the side portion of the oil outlet pipe, the stability is higher, the sensitivity to the fuel pressure is higher, the response speed is higher, the on-demand oil supply capacity of the oil supply module is higher, and fuel oil can be effectively saved.

The invention is suitable for the field of ship control, and provides a ship autonomous berthing control method which comprises the following steps: S11, making an autonomous berthing control strategy; s12, establishing a ship propulsion system model; s13, calculating the thrust and the vector angle of the thruster; according to the invention, the double-pod thruster is adopted to directly drive the propeller, so that the complex shafting transmission loss of a traditional lateral thrust device is eliminated, and the pod streamline design reduces the resistance of an appendage; compared with a traditional lateral thrust device, 15%-25% of fuel oil / electric charge can be saved through long-term operation, meanwhile, the double pods are basically free of maintenance, the maintenance cost is reduced, hardware arrangement does not need to be planned in the early design stage, and the ship design flexibility is improved.

The two power supply systems are used as a source of energy of the whole harvester, the power management system is used for distributing electric power, and the power utilization system is used for driving all working parts of the extended-range hybrid power electric drive harvester to work. Therefore, double power supplies of extended-range power supply and power battery are adopted to provide power for the whole machine, sufficient endurance operation time is ensured, a motor type can save fuel oil, reduce carbon emission and improve operation precision, the electric power framework is a brand-new electric power framework, and a transmission path is simplified through motor direct drive, so that oil consumption and the failure rate of a transmission system are reduced, and the service life of the whole machine is prolonged. And the direct-drive response speed of the motor is high, and the speed regulation range is wide.

Present invention teaches a foldable truck rack that can be collapsed down when not in use, saving gas consumption and adding flexibility of space utilization of the bed portion of a pickup truck. 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.

The newly developed exhaust valve and the modified side of the intake valves replace the conventional design in gasoline engines as well as the conventional valve control. The exhaust valve is a unit consisting of sleeves, valve tappet and coil spring, made of metal or ceramic. The high labor costs for manufacturing, material costs and energy consumption are thereby drastically reduced, not only in the production of the motors but also in operating costs.
