Description

Technical Field

[0001] The invention relates to the technical field of an electronically sprayed waterproof and flameout-proof engine for an outboard motor, and in particular to an electronically sprayed waterproof and flameout-proof engine for an outboard motor and a use method thereof. Background Art

[0002] An outboard motor is a ship auxiliary device that uses fuel to drive. It is connected to the ship's transmission system to transmit power to the ship's propeller, thereby propelling the ship. It plays an important role in modern shipping because it has faster speed and better maneuverability. Ships can reach their destination faster in a shorter time through outboard motors. Outboard motors consist of two main parts: engine and propeller. The engine is usually a two-stroke or four-stroke internal combustion engine. By controlling the throttle and direction transmission lever, the size and direction of the thrust can be controlled, thereby driving the propeller to rotate and achieve the purpose of the ship's travel. There are two main types of propellers: fixed and adjustable. Fixed propellers consist of propellers and fixed thrusters. This type of propeller is suitable for low-speed ships or ships that need to be operated at low speed. Adjustable propellers can adjust the angle of the propeller as needed, thereby adjusting the size and direction of the propulsion force. It is suitable for high-speed ships or ships that need to be operated quickly. The main advantages of outboard motors include good ship maneuverability, fast speed, simple maintenance, etc.

[0003] However, the main reasons for intermittent flameout of existing engines are: 1. malfunction of spark plugs, 2. leakage of vacuum tubes, 3. leakage of high-voltage wires, 4. blockage of PCV valves, 5. failure of throttle position sensor, 6. failure of idle stepper motor, 7. malfunction of idle control valve, 8. abnormal throttle opening, and 9. leakage of intake system. There are two reasons why the fuel supply system causes the engine to flame out. One is that no fuel is sprayed out, and the other is that the amount of fuel sprayed is too small. If two fuel pumps are used, they are divided into a main fuel pump and an auxiliary fuel pump. The gasoline in the cylinder of the electronic fuel injection engine is directly sprayed out by the fuel injector, which is installed on the fuel injection pipe. The fuel in the fuel injection pipe is pumped by an electric fuel pump installed in the gasoline tank and then supplied by a fuel filter (pressure regulator). In the entire fuel supply system, the fuel injector and the electric fuel pump are controlled by a control computer or a relay. Therefore, the present application provides an electronic fuel injection waterproof and flameout-proof engine for outboard motors and a method for using the same to meet the needs. Summary of the invention

[0006] Preferably, the propeller assembly comprises a propeller housing, a power motor is arranged inside the propeller housing, and a connecting housing is connected to the bottom of the propeller housing. The bottom of the connecting housing is connected to the shark fin housing.

[0007] Preferably, one side surface of the shark fin shell is connected to a connecting and fixing rod, one end of the connecting and fixing rod is connected to an underwater auxiliary propulsion disc, a fixing piece is connected to the center of one side surface of the underwater auxiliary propulsion disc, and the other side surface of the underwater auxiliary propulsion disc is provided with a plurality of propeller pushing blades in a matrix form.

[0008] Preferably, the generator waterproof housing assembly includes a waterproof housing body, a mounting hole is provided on the front surface of the waterproof housing body near the top edge, a direction control handle is connected to the front surface of the waterproof housing body near the bottom edge, a plurality of first water flow grooves are arranged on the front and rear side surfaces of the waterproof housing body, and a plurality of second water flow grooves are arranged on the right side surface of the waterproof housing body.

[0009] Preferably, the oil tank assembly comprises a main oil tank, and a first auxiliary oil tank and a second auxiliary oil tank are respectively connected to the left and right sides of the main oil tank.

[0010] Preferably, the controller assembly includes a generator main controller body, and the left and right sides of the generator main controller body are respectively connected to the first auxiliary vacuum tube connection compartment and the second auxiliary vacuum tube connection compartment, and the front surface of the first auxiliary vacuum tube connection compartment is connected to the generator manual switch.

[0011] Preferably, the oil inlet assembly includes an oil inlet pipe, the left and right side surfaces of the oil inlet pipe are respectively connected to auxiliary oil inlet pipes, the top of the oil inlet pipe is connected to a fuel injector, and the top surface of one of the auxiliary oil inlet pipes is connected to an intake monitor.

[0012] Preferably, the air flow meter assembly includes an air flow meter, the bottom of the air flow meter is connected to a connecting pipe, the top of the air flow meter is connected to a double-headed air connecting pipe, and an auxiliary external interface is opened at the center of the front surface of the air flow meter.

[0013] Preferably, the vacuum tube assembly includes a vacuum generator, one end of the vacuum generator is connected to an air filter, the other end of the air generator is connected to a vacuum tube, one end of the vacuum tube is connected to a vacuum tube clearer, and the outer surface of the vacuum tube is wrapped with a vacuum tube protective shell.

[0014] The method for using the electronic injection waterproof and flameout-proof engine for outboard motor comprises the following steps: Step 1: Installation step: Place the fuel tank assembly and the controller assembly on top of the thruster assembly, and cover the top surface of the fuel tank assembly and the controller assembly with the generator waterproof housing assembly, wherein two fuel pumps are installed inside the fuel tank assembly, and are respectively equipped with two fuel inlet assemblies, fuel injection pipes and air flow meter assemblies, and a vacuum tube assembly is installed on both sides of the controller assembly; Step 2: The power motor of the propeller assembly is started to drive the propeller at the bottom to push the blades for rotational propulsion. The shark fin shell is in the shape of a shark fin. As an auxiliary propulsion effect, the three fuel tanks in the fuel tank assembly structure are first filled. The fuel pump and the fuel inlet assembly will mainly absorb the fuel inside the main fuel tank when they are started for the first time. When there is a problem with the fuel supply system, the auxiliary fuel tank and the auxiliary fuel pump can be started again using the switch, and the auxiliary fuel inlet pipe can be used to prevent flameout; Step 3: The two vacuum tube assemblies also prevent the flameout caused by the failure to replace the vacuum tube in time due to the rupture of the vacuum tube.

Most electronic fuel injection generators are only equipped with one fuel pump. There are two reasons why the fuel supply system causes the engine to stall. One is that there is no fuel spraying, and the other is that the amount of fuel sprayed is too small. If two fuel pumps are used, they are divided into a main fuel pump and a secondary fuel pump. The gasoline in the cylinder of the electronic fuel injection engine is directly sprayed by the fuel injector, and the fuel injector is installed on the fuel injection pipe. The fuel in the fuel injection pipe is pumped by the electric fuel pump installed in the gasoline tank. In the entire fuel supply system, the fuel injector and the electric fuel pump are controlled by a control computer or a controller component. In addition, it is possible that the air flow meter is damaged, resulting in inaccurate intake volume monitoring and leakage of the vacuum hose installed on the fuel regulator. Therefore, two vacuum tube assemblies and two air flow meter assemblies are also installed, one is the main one and the other is the secondary one. If there is a problem during the first use and it causes the flameout, it can be immediately started to assist in continued use, to prevent a single system generator from being paralyzed in place and unable to move after flameout.

[0016] By covering the generator surface with a generator waterproof shell assembly, external water sources can be well isolated, and when it rains, rainwater can flow along the water flow grooves opened on the surface without causing surface water accumulation.

The oil tank assembly 3 includes a main oil tank 301, and a first auxiliary oil tank 302 and a second auxiliary oil tank 303 are connected to the left and right sides of the main oil tank 301, respectively.

[0027] The electric fuel pump is generally installed in the gasoline tank. The fuel has a good cooling effect on the oil pump. Two fuel pumps are divided into a main fuel pump and an auxiliary fuel pump. When the main fuel pump is blocked, the auxiliary fuel pump can be used immediately to continue using it. The gasoline in the cylinder of the electronic fuel injection engine is directly sprayed out by the fuel injector. The fuel injector is installed on the fuel injection pipe. The fuel in the fuel injection pipe is pumped by the electric fuel pump installed in the gasoline tank. In the entire fuel supply system, the fuel injector and the electric fuel pump are controlled by the control computer or controller component 4. In addition, it is possible that the air flow meter is damaged, resulting in inaccurate intake volume monitoring and leakage of the vacuum hose installed on the fuel regulator. Therefore, two vacuum tube assemblies 9 and two air flow meter assemblies 8 are also installed, one is the main one and the other is the auxiliary. If a problem occurs during the first use and the flameout occurs, it can be immediately started to assist in continued use, preventing a single system generator from being paralyzed in place and unable to move after flameout.

[0028] The generator waterproof housing assembly 2 and the thruster assembly 1 are both made of waterproof materials to prevent water from entering the interior and affecting the generator during use and rain.

[0029] The underwater auxiliary propulsion disc 106 can increase the contact area of ​​the underwater propulsion structure, and the propulsion efficiency can be increased to a certain extent by cooperating with the propeller to push the blades 108 and the power motor 104.

[0030] like Figures 7 to 11 As shown, in this embodiment, the controller assembly 4 includes a generator main controller body 401, and the left and right sides of the generator main controller body 401 are respectively connected to a first auxiliary vacuum tube connection compartment 402 and a second auxiliary vacuum tube connection compartment 403, and the front surface of the first auxiliary vacuum tube connection compartment 402 is connected to a generator manual switch 404, and the oil inlet assembly 6 includes an oil inlet pipe 601, and the left and right side surfaces of the oil inlet pipe 601 are respectively connected to auxiliary oil inlet pipes 602, and the top of the oil inlet pipe 601 is connected to an oil nozzle 603, and the top surface of one of the auxiliary oil inlet pipes 602 is connected to an intake monitor 60 4. The air flow meter assembly 8 includes an air flow meter 801, the bottom of the air flow meter 801 is connected to a connecting pipe 802, the top of the air flow meter 801 is connected to a double-headed air connecting pipe 804, and an auxiliary external interface 803 is opened at the center of the front surface of the air flow meter 801. The vacuum tube assembly 9 includes a vacuum generator 901, one end of the vacuum generator 901 is connected to an air filter 902, the other end of the air generator 901 is connected to a vacuum tube 903, one end of the vacuum tube 903 is connected to a vacuum tube dredger 904, and the outer surface of the vacuum tube 903 is wrapped with a vacuum tube protective shell 905.

[0031] The vacuum tube assembly 9, the air flow meter assembly 8, and the oil inlet assembly 6 are all matched with the fuel pump 5 to adapt two sets, one is the main one and the other is the secondary one, so as to improve the safety. When driving on the water, if there is only one system and it cannot be used after the engine is turned off, the danger is much greater than the engine being turned off on the road. Therefore, the two systems are used alternately to avoid the problem of being unable to move further due to engine being turned off.

[0032] like Figures 1 to 11As shown, in this embodiment, after the existing electronic fuel injection generator is turned off, the fuel pump should be checked according to the following method: turn on the ignition switch ("ON" position), listen to whether the fuel pump has any running sound, if there is an obvious running sound, it means that the fuel pump is working normally (but for the engine using the wing plate air flow meter, since the fuel pump control switch is provided in the air flow meter, after turning on the ignition switch, it is necessary to start the engine to check the working condition of the fuel pump). When checking, in addition to listening to the sound, you can also pinch the fuel supply hose with your hand, you should be able to feel the pressure of the oil, when the pinched oil pipe is loosened, the oil pipe should be able to recover immediately. Of course, if the method of loosening the return oil pipe joint is adopted to check whether the oil is sprayed outward from the oil pipe, it can further prove the quality of the oil pump. After checking that the oil pump is faulty, the fault should be eliminated. If there is no problem with the oil pump, the next step should be to check the injector. The injector failure that causes the engine to stall is often caused by injector blockage or The control circuit fails. The reason for the failure of the injector is the deposits and carbon deposits on the injector nozzle, which reduces the amount of fuel injected by the injector or makes the injection unstable. A simple way to check the blockage of the injector nozzle is: remove the injector, connect the oil supply branch and the oil carrying pipe, connect a 3V power cord to the injector wire connector or use a special resistor wire to touch the positive pole of the battery. If the injection is crisp and the oil is stopped in time, it is normal. Once the injector nozzle is blocked, it should be cleaned on a special cleaning machine, or without removing the injector, use a cleaning agent mixed with gasoline to clean the injector nozzle through the gasoline pipeline on the car. The normality of the injector control circuit can also be checked when the engine is started. Put your finger on the injector to feel whether the injector vibrates. If so, it means that the control circuit is working properly. Otherwise, check whether the wire connector to the control computer is open circuit according to the wire number indicated in the manual, or whether the control computer itself is faulty.

[0033] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0034] When using the electronic injection waterproof and flameout-proof engine for outboard motor, the following steps are included: Step 1: Installation step: Splice the fuel tank assembly 3 and the controller assembly 4 and place them on the top of the propeller assembly 1, and cover the top surface of the fuel tank assembly 3 and the controller assembly 4 with the generator waterproof housing assembly 2, wherein two fuel pumps 5 are installed inside the fuel tank assembly 3, and are respectively equipped with two fuel inlet assemblies 6, a fuel injection pipe 7 and an air flow meter assembly 8, and in addition, a vacuum tube assembly 9 is installed on both sides of the inside of the controller assembly 4; Step 2: The power motor 104 of the propeller assembly 1 is started to drive the propeller at the bottom to push the blades 108 to rotate and propel. The shark fin shell 103 is in the shape of a shark fin. As an auxiliary propulsion effect, the three fuel tanks in the fuel tank assembly 3 structure are first filled. The fuel pump 5 and the fuel inlet assembly 6 will mainly absorb the fuel inside the main fuel tank 301 when they are started for the first time. When there is a problem with the fuel supply system, the auxiliary fuel tank and the auxiliary fuel pump can be started again by using the switch, and the auxiliary fuel inlet pipe 602 can be used to prevent flameout; Step 3: The two vacuum tube assemblies 9 also prevent the flameout caused by the failure to replace the vacuum tube in time due to the rupture of the vacuum tube. The vacuum generator 901 and the air filter 902 can extract air to ventilate the internal generator. The vacuum generator 901 can also be used to keep the vacuum tube 903 in a vacuum state. If the vacuum tube 903 is blocked by an accident, the vacuum tube dredger 904 connected at one end can be used for self-cleaning and dredging. Step 4: Finally, cover the generator with a waterproof housing assembly 2 to isolate the generator from external water sources. When it rains, the rainwater can flow along the water troughs on the surface without causing surface water accumulation.

[0035] The technical solution provided by the present invention is as follows: first, the electric fuel pump is generally installed in the gasoline tank, and the fuel has a good cooling effect on the fuel pump. Most electronic fuel injection generators are only equipped with one fuel pump. There are two reasons why the fuel supply system causes the engine to stall. One is that there is no fuel spraying, and the other is that the fuel injection amount is too small. If two fuel pumps are used, they are divided into a main fuel pump and an auxiliary fuel pump. The gasoline in the cylinder of the electronic fuel injection engine is directly sprayed by the fuel injector, and the fuel injector is installed on the fuel injection pipe. The fuel in the fuel injection pipe is pumped by the electric fuel pump installed in the gasoline tank. In the entire fuel supply system, the fuel injector and the electric fuel pump are controlled by a control computer or a controller component 4. In addition, it is also possible that the air flow meter is damaged, resulting in the intake volume monitoring In order to prevent inaccuracy and leakage of the vacuum hose installed on the fuel regulator, two vacuum tube assemblies 9 and two air flow meter assemblies 8 are also installed, one is the main one and the other is the auxiliary one. If there is a problem during the first use and it causes the flameout, it can be immediately started to assist in continued use, preventing a single system generator from being paralyzed and unable to move after flameout. Then, by covering the generator surface with the generator waterproof shell assembly, the external water source can be well isolated, and when it rains, the rainwater can also flow along the water flow grooves opened on the surface without causing surface water accumulation. The shells of the generator waterproof shell assembly 2 and the propeller assembly 1 are both made of waterproof materials to prevent water from entering the interior during use and during rainy periods and affecting the generator.

[0036] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
