Lawn mower carburetor working principle

A lawn mower is a common agricultural and gardening tool used to mow grass and mow lawns. The lawn mower is very convenient, but it needs fuel to work. After the fuel is processed by the carburetor, it is delivered to the engine for combustion, thereby driving the work of the lawn mower. The working principle of the carburetor of the lawn mower will be introduced below. Carburetor is a kind of precision mechanical equipment, mainly composed of four main parts:(1) fuel tank, (2) fuel pipe, (3) nozzle, (4) valve. When the lawn mower is working, the working process of the carburetor is as follows: 1. The fuel tank provides fuel. Fuel is stored through the tank and enters the carburetor through the fuel tube. The fuel in the tank is usually gasoline. The size and shape of the fuel tank varies from one lawn mower to another. 2. The fuel enters the carburetor through the fuel pipe. The fuel pipe delivers fuel to the carburetor. The fuel pipe is usually an elongated pipe whose main function is to convey fuel from the tank to the carburetor. 3. The carburetor vaporizes the fuel into gas. The carburetor vaporizes the fuel into a gas, which is then mixed with air. The mixed gas flows into the engine through the nozzle. 4. Air enters the carburetor through the valve. The air in the carburetor enters through the valve, mixes the incoming air with fuel and delivers it to the nozzle. 5. The nozzle sprays the mixed gas. The nozzle sprays the mixed gas and sends it to the engine. When the gas mixture caught fire, the engine began to run. 6. The air supplied by the bucket cools the engine. The bucket continuously introduces airflow into the engine at a certain speed. The airflow passes through the engine, taking away the heat generated by the engine. Therefore, the working principle of the lawn mower carburetor is to make a mixed gas through the carburetor, and then deliver the mixed gas to the engine. In this way, the mower can work properly. The carburetor is a very important device that can ensure that the lawn mower has enough power when working.

Outboard engine carburetor maintenance and maintenance

The carburetor is a mechanical device that mixes and atomizes fuel and air in a certain proportion during engine operation. We know that engine operation requires three major elements: air, fuel, and ignition. These three burn in the cylinder to generate power. In order to ensure complete and rapid combustion, it is necessary to premix air and fuel in proportion before entering the cylinder to form Mist fuel, the device that undertakes the task of premixing, is the carburetor. Figure 1 A two-stroke engine carburetor From the above description and pictures, we can know that the carburetor can be simply regarded as a "three-way pipe", which takes in air (damper) all the way, fuel (oil circuit, fuel pump) all the way, and outputs mixed mist fuel all the way. Features of 2. outboard engine carburetor Compared with other fire rescue equipment, the two-stroke outboard carburetor has two obvious characteristics. One is that the air inlet (air door) has no air filter, which is to prevent the air filter from absorbing water and damp and inputting humid gas to the engine. The second is that the outboard engine used for water rescue has a greater risk of falling into water, so it is necessary to study its drainage operation method. Figure 2 Carburetor for outboard motor It can be seen from Figure 2 that the carburetor is not only responsible for a simple "carburetor" function. In fact, it is a "logistics support center control panel" serving the cylinder. It "feeds" the cylinder with appropriate fuel and air. It can adjust the idle speed (actually adjust the minimum opening angle of the throttle valve of the atomized fuel output pipe) and adjust the air-fuel mixing ratio. At the same time, the role of the throttle and throttle is also reflected by the carburetor. Fig. 3 Disassembly diagram of carburetor It can be clearly seen from Figure 3 that the carburetor is connected to the two major components of intake and combustion, and the carburetor is in the middle position. 3. carburetor water emergency maintenance As mentioned above, the outboard aircraft used in water rescue has a great risk of falling into the water, so it is of practical significance to deal with the emergency of the outboard aircraft. For the overall emergency treatment of the outboard motor, please refer to the article "Gankun (2) in the cylinder" before this public number. Here, only the carburetor inlet water treatment is introduced. After the outboard engine falls into the water, the water will quickly enter the carburetor along the intake duct, and then enter the oil circuit and cylinder. Therefore, the carburetor is the "severe disaster area" and "flood storage area" for the water intake, and the drainage efficiency is high at the carburetor position., The effect is good. The oil pan of the carburetor itself is equipped with a drain valve, which can be used to drain water after entering the water. Figure 4 Carburetor sump and drain valve (external) Fig. 5 Oil Pan Disassembly Figure 6 The internal structure of the carburetor After the outboard motor falls into the water, before pulling the start rope to drain the water, you can use a screwdriver to loosen the drain valve (Figure 7). At this time, pull the start rope to drain the water, the drainage efficiency will be improved, and it will also help drain sediment impurities, which is conducive to emergency maintenance and start-up. Fig. 7 Loosening the drain valve It should be specially stated here that in the implementation of emergency maintenance in the water rescue environment, safety should be the first priority, and the carburetor should be dismantled for faults such as outboard aircraft falling into the water. the carburetor should be handled only by loosening the drain bolt and draining water according to the method shown in fig. 7.

The method of detecting the working height of the carburetor oil float

Whether the working height of the carburetor oil float meets the technical requirements has a great impact on whether the carburetor can work normally. When the carburetor is overhauled and adjusted, the working height of the oil float needs to be tested to confirm whether its working height meets the technical requirements. The commonly used detection method is to remove the carburetor from the engine, twist the fastening screws of the float chamber, remove the float chamber shell, and then turn the carburetor body upside down, so that the oil float will naturally droop under the action of its own weight. Close the triangular needle valve, and then use a special measuring tool to detect whether the working height of the oil float meets the technical requirements. Most carburetors can use this method for detection. However, some carburetor (such as vacuum carburetor more) can not use this method for testing, mainly triangular needle end of the spring elasticity is not the same. The spring at the end of the triangular oil needle of this carburetor is especially soft. When detecting the working height of the oil float, the carburetor body is inverted. Under the action of its own weight, the oil float not only closes the triangular needle valve, but also compresses the spring at the end of the triangular oil needle. As a result, the actual working height of the oil float is much lower than the standard height. Therefore, it is difficult to ensure the correctness of the detection data, it also brings some trouble to correctly adjust the working height of the oil float, but the use of this triangular needle valve has certain advantages. When the motorcycle is driving on uneven roads, it will produce greater vibration, and the oil level of the carburetor will fluctuate, and the oil float will float up and down under its influence. Ordinary triangular needle will open the triangular needle valve abnormally frequently, which will lead to abnormal oil level, it has a certain impact on the normal operation of the engine, and the special soft spring at the end of the triangle oil needle can avoid and eliminate this situation. When the triangular needle valve works, the triangular needle valve is closed first, and then the spring at the tail end of the triangular oil needle is compressed. Therefore, when the oil level fluctuates greatly, the oil float will float up and down, but due to the buffering effect of the spring at the tail end of the triangular needle, the triangular needle valve will not be opened abnormally frequently, thus ensuring that the oil level always maintains a normal height. Therefore, the carburetor equipped with this kind of triangular oil needle, the working height of the oil float cannot be detected by regular methods. The detection method that should be used is to remove the carburetor and remove the float chamber shell, use a clean rubber tube about 200mm long, insert one end into the oil inlet nozzle of the carburetor, and hold the other end in the mouth. Hold the carburetor with both hands according to the working position, while blowing continuously, while gently lifting the oil float with your fingers, when blowing, the air will produce airflow noise through the unclosed triangular needle valve, when the sound of the air flow just disappeared, it means that the triangular needle valve has been closed. At this time, the position of the oil float is the working height of the oil float. The finger immediately stops supporting the oil float and keeps the original position still. Then use a special measuring tool for testing to confirm whether the working height of the oil float meets the technical requirements.

Banana water gives carburetor a new look

Can you know that the carburetor can achieve the effect that the banana water is clear? When the carburetor is repaired, the decomposition parts are usually soaked in gasoline, and then the compressed air is blown clean by hand. Since gasoline cannot dissolve all the dirt in the oil passage, the cleaning effect is not ideal. The dissolution and penetration capacity of banana water is significantly greater than that of gasoline. Using banana water to clean the carburetor can remove all kinds of fouling inside and outside the carburetor and restore the carburetor as new.
