New energy-saving tractor

With the development of the rural economy, agricultural machinery has entered millions of households, but most operators have a weak concept of fuel economy, heavy use, and light maintenance, which deteriorate the technical status of tractors and agricultural transport machinery, reduce power, increase fuel consumption, and waste fuel. polluted environment. This article introduces several new technologies for diesel engine energy saving that are available to readers.

1. Diesel Engine Tester Diesel Engine Tester is an instrument that optimizes the commissioning technology. It has a simple structure, is convenient to carry and operate, and has good use effect. It can be based on the detection of valve clearance, valve timing, fuel injection pressure and supply. Adjust the oil advance angle, etc. After adjustment, generally increase the power by 10% to 20% and the fuel consumption by 5% to 10%. For parts that have reached the limit of wear, a clear diagnosis can be made for timely replacement.

2. Inertia booster fuel economy technology Inertia booster is the use of the inertial and fluctuating effects of the airflow in the intake manifold of a diesel engine to increase the amount of air entering the cylinder. It does not require special pressurizing equipment. It only needs to lengthen the intake pipe of the diesel engine properly and install a cylinder equal to the cylinder volume in the filter. Using this method, the power can be increased by 10% to 20%, the fuel consumption can be reduced by 3% to 8%, and the exhaust smoke color can be improved, which is a viable way to save energy and reduce environmental pollution. The inertial boosting technology makes the engine have better fuel economy and power increase when operating under rated power or overload; however, the fuel saving effect is not obvious under light load.

3, diesel negative pressure fuel economy technology Negative pressure fuel economy technology is to reduce the gas pressure in the oil tank (oil pan), and maintain a certain negative pressure value, in order to achieve a technical measure to reduce diesel engine oil consumption. According to national standards, the normal consumption of oil is generally not more than 6.68g/kW?h at rated power, but in fact, many engine oil consumption rates are as high as 13.6~27.2g/kW?h, accounting for 5 of the main fuel consumption. %, individual even reached 25%. The main reason for high oil consumption is due to wear of parts and increased clearance, especially after the wear of pistons, cylinders and piston rings. Part of the exhaust gas after combustion is pumped into the crankcase to increase the temperature and pressure of the oil in the crankcase. , Thinning, deterioration, increase the possibility of leakage of oil, but also increase the amount of oil pumped to the cylinder in the diesel engine suction and compression stroke, which increases the consumption of oil. If a negative pressure device is added, the negative pressure in the crankcase can be increased to reduce the oil pumping effect of the piston and the piston ring. The principle of the negative pressure device is to utilize the negative pressure formed in the intake stroke cylinder to suck the exhaust gas with a higher pressure in the crankcase into the cylinder through labyrinth-type air passages and plastic pipes so that the unburned fuel can continue to burn. , thus reducing oil consumption.

4. Metal cleaning agent Metal cleaning agent is a kind of water-based chemical cleaning agent developed and promoted in recent years in China, and its decontamination ability is strong. In general, 1 kg of liquid (or solid) can replace 8 to 12 kg of gasoline, which is a good energy-saving measure for replacing oil with water. The main component of the metal cleaning agent is the surface active material, which is also the main body of cleaning and decontamination. Surfactant molecules are divided into two parts, one part is active, soluble in water, called hydrophilic base; the other part is non-active, insoluble in water, and is called water-based. The hydrophobic base has the property of oleophilicity. In the washing process, after it comes into contact with the dirt on the metal surface, one end of it attracts the oil in the dirt and penetrates into the oil drop to generate a wetting action and the dirt particles are crushed into colloidal size. Particles dispersed in water. One end of the water-soluble hydrophilic base is inserted into the water from the outer surface of the oil droplet, and the oil droplet is wrapped in the middle of the water. After friction and vibration, the large oil droplets are dispersed into small oil beads, thereby reducing the adhesion of the dirt on the metal surface. . Surfactant molecules are both in contact with the dirt surface and in contact with the metal surface. Since the adsorptive force between the active material and the metal surface is much smaller than the adsorption force of the dirt on the metal surface, the grease easily separates from the metal surface and disperses into the water to form the emulsion. Liquid to achieve the purpose of washing. The use of water-based metal cleaners is as simple as dissolving it in water. The used cleaning fluid can be used after clarification to remove the dirt. The cleaning solution can be used at room temperature, but the cleaning ability is also increased with increasing temperature. The shortcomings of this cleaning agent are: the storage time of the parts should not be too long, otherwise it must be taken to prevent rust. In addition, precision coupling parts such as the plunger pair, the outlet valve pair, and the needle valve pair of the injector cannot be cleaned with this cleaning agent. Therefore, it is not possible to completely replace the oil-based cleaning agent with the water-based cleaning agent.
