How to use diesel generators to save fuel?

A few ways to save fuel with a diesel generator:

1. Diesel purification. Diesel contains a variety of minerals and impurities, if not precipitated, filtered and purified, it will affect the work of the plunger and fuel injection head, resulting in uneven oil supply, poor oil atomization and other phenomena, so that the engine power decreases and fuel consumption increases. Therefore, it is recommended to let the diesel stand for a period of time to allow impurities to settle, and then filter the funnel and filter when refueling.

2. Remove carbon deposits. In the operation of diesel engines, there are polymers attached to the valves, valve seats, fuel injectors and pistons.

3. Do not overload the work. Black smoke is emitted when machinery is overloaded, which is fuel emissions that are not fully burned.

4. Keep the water warm. If the cooling water temperature of the diesel engine is too low, the diesel combustion will be incomplete, which will affect the power play and waste fuel. Therefore, it is necessary to use thermal curtains appropriately.

5. Regular inspection and timely repair. To be diligent in eyes and hands, to regularly or irregularly inspect the machinery, diligent maintenance, diligent repair, do not let the machinery with sick operations. Learn more about technical issues, search Daze Power, He Mengde.

Gasoline generators and diesel generators have their own advantages as a whole, and there is no good or bad between the two, but they play different roles according to their uses. Diesel generators are used in large public places, or construction sites, the power utility is large, but relatively speaking, the noise is a little loud but very fuel-efficient, for the reputation of slow public use, is very economical. But the gasoline generator does not have such a large horsepower, but the gasoline generator set is less noisy, easy to carry, but compared with the diesel generator Qing Mo fuel consumption is slightly larger, another point is to consider the place of use, diesel generator weather requirements are higher, you like the northern winter may not be easy to start some times need starting fluid to start.

A certain percentage of the oil is mixed.

Household portable generators are made of gasoline or oil mixed with gasoline and engine oil in a certain proportion. It mainly depends on the structural type of generator power, four-stroke (intake, pressure, explosion, exhaust) with gasoline, two-stroke (intake with compression, burst with exhaust) with mixed oil. No matter what the generator is, they must be lubricated with oil.

Difference Between Gasoline Generator and Diesel Generator:

The construction of the two is basically the same, and one obvious difference can be found from their names: the required burning materials are different. Diesel has a relatively high calorific value, while gasoline burns more smoothly in comparison.

The power is different. In the same way that a diesel-burning car has more horsepower than a gasoline-burning car, the minimum power of a diesel generator set is 8 kilowatts, and the maximum power can reach 2,000 kilowatts, and the maximum power of gasoline of the same volume can only reach 10 kilowatts.

The ignition type is different. In the cylinder of a gasoline engine, the mixture of fuel and air is ignited with a spark plug. In a diesel engine, the mixture is ignited with the heat formed by compression.

The volume is different. The gasoline engine is small in size, easy to handle, and suitable for mobile power supply.

Fuel and air are mixed differently. In a gasoline engine, fuel and air are mixed in the carburetor and intake ducts. In a diesel engine, the mixing of fuel and air takes place after the diesel fuel is sucked into the cylinder.

The main uses are different. Diesel engines are mainly used for industrial power supply, and gasoline engines are generally selected for household use. <>

1。Buying a high-efficiency diesel engine, after all, the processing accuracy is high, and the diesel engine with reasonable design is fuel-efficient.

2。Maintain the good performance of the diesel engine, and the good performance can reduce the waste of energy.

3。Try to keep the diesel engine running smoothly and avoid frequent changes in load to save fuel use.

4。The exhaust gas of the diesel engine is rationally utilized, and the exhaust gas turbocharger is added to the large diesel engine to improve efficiency.

5。Different ambient temperatures, use suitable lubricating oil to avoid energy loss caused by excessive viscosity of lubricating oil.

6。Keep the diesel engine cooling water at a reasonable temperature, the temperature of the cooling water is too low is also a kind of energy loss.

7。Keep the inlet air temperature of the diesel engine reasonable, too low the inlet air temperature will also increase fuel consumption (diesel engine with air cooler).

8。As much as possible, let the diesel engine work at more than 40% of the full load, because the diesel engine has to overcome its own resistance and consume energy, and the low load greatly reduces the mechanical efficiency. For example, no-load operation also consumes fuel, but the mechanical efficiency is 0, but try not to overload.

1. When it is found that the oil consumption is excessive, you should first check whether there is oil leakage between the body and the gear chamber cover, the first side of the wheel, the back cover, the cover and other connections. If there is oil leakage, attention should be paid to whether the sealing gasket of the random joint part of each key jujube is complete, and the damaged gasket should be replaced.

If the gasket is complete, check whether the connecting screws in each part are loose.

For loose bolts, use a wrench to reach the specified torque. If the above parts are basically normal, and the oil leakage is in the frame position, the oil shell should be inspected, the main inspection part is at the front end of the oil shell side on the same side as the traveling wheel, mostly due to the loosening of the base screws, the traveling wheel is pulled by the V-belt and the angle iron of the machine rock round frame that protects the oil shell for a long time, and the oil shell is worn through to form a gap and produces oil leakage.

2. The normal wear and tear caused by the long-term use of the engine, or the abnormal wear and tear caused by improper maintenance, will cause the cylinder liner of the diesel generator to form longitudinal pull marks, and the cylinder bore and piston side clearance exceed the specified value, so that the supporting force of the piston ring will be reduced accordingly, and the oil scraping will be unclean.

Or because the inner support twisting spring in the oil ring is disconnected at the opening position of the oil ring, resulting in the oil scraping is not clean and participates in combustion, resulting in serious oil consumption symptoms, which is manifested as the difficulty of starting the diesel engine, the exhaust pipe has obvious blue smoke coming out, and the respirator is seriously injected.

In addition, the piston should be on the upward side, in the assembly due to the direction of the inversion of the combustion chamber to form an inverted state, although it will not affect the start of the diesel engine, but the loss of oil will be quite serious, the daily fuel consumption is about kilograms.

3. Although it is rare that the valve guide is seriously worn and will burn the oil of the diesel generator set, it is also a reason that cannot be ignored according to the introduction of the relevant information in the manuscript file.

The fuel-saving and energy-saving methods of diesel generators are as follows:

1. Increase the temperature of the cooling water of the diesel generator set

The increase of cooling water temperature can increase the temperature of the generator set fuselage, which not only promotes the more complete combustion of diesel, but also reduces the viscosity of the oil, thereby reducing the resistance of movement and achieving the effect of fuel saving.

2. Purify the oil before use

About 60% of the faults of diesel generator sets come from the oil supply system, so they must be dealt with before adding oil to the generator set. The method of treatment is as follows: the purchased diesel fuel is put aside for about 2-4 days before use, which can precipitate about 98% of impurities.

The purpose of oil treatment is to make the diesel generator set more fuel.

3. Within the rated power, do not overload the use

When using the generator set, it is best to use it within the rated power, and do not overload it, otherwise it will achieve the purpose of fuel saving. Overload operation not only affects the life of the generator set, but also greatly increases the fuel consumption, the general load rate is controlled at a reasonable level, and the load rate is between 50% and 80% more fuel-efficient.

4. Increase the diesel engine pulley and turn it into a "big horse-drawn trolley".

Appropriately increasing the diesel engine pulley can increase the speed of the water pump under the condition that the diesel generator set is running at reduced speed, so that the flow rate and head can be increased, so as to achieve the purpose of energy saving.

5. Regular maintenance of diesel generator sets

Normal wear and tear will be formed when the engine is used for a long time, and if it is not properly maintained, abnormal wear will be formed, resulting in the formation of longitudinal pull marks in the cylinder liner of the diesel generator, the cylinder bore and piston side clearance exceed the specified value, and the supporting force of the piston ring will be reduced accordingly, and the oil scraping will be unclean.

Secondly, because the inner support twisting spring in the oil ring is disconnected at the opening position of the oil ring, the oil scraping is not clean and participates in combustion, resulting in serious oil consumption symptoms, which is manifested as the difficulty of starting the diesel engine, the obvious blue smoke coming out of the exhaust pipe, and the serious fuel injection of the respirator.

Furthermore, the piston should be on the upward side, in the assembly due to the direction inversion of the combustion chamber to form an inverted state, although it will not affect the start of the diesel engine, but the loss of oil will be quite serious, the daily oil consumption is about kilograms, so be sure to carry out regular maintenance of the diesel generator set.

6. Ensure that the machine does not leak oil

Diesel generator oil pipelines are often due to uneven joint surfaces, gasket deformation or damage surfaces and loopholes. The solution is to coat the gasket with valve paint and put it on the glass plate to smooth it and straighten the oil pipe joint. Add a diesel ** device, and the oil return pipe on the oil nozzle can be connected with the hollow core screw with a plastic pipe, so that the oil return flows into the fuel tank.

7. Maintain the best oil supply angle

If the oil supply angle is offset, it will cause the oil supply time to be too late, and the fuel consumption will increase greatly.

Increase the temperature of the cooling water of the diesel engine, the increase of water temperature can make the diesel fuel more complete combustion, the viscosity of the oil will be small, the movement resistance can be reduced, and the fuel saving effect can be achieved;

To ensure that the machine does not leak oil, the diesel engine oil pipeline is often uneven due to the uneven joint surface, and there are loopholes in the deformed or damaged surface of the gasket, and the solution is to coat the gasket with valve paint and grind it on the glass plate;

Positive oil pipe joint, add diesel ** device, you can use a plastic pipe to connect the oil return pipe on the nozzle with the hollow core screw, so that the oil return flows into the fuel tank.

Try to make the fuel combustion of the diesel generator set sufficient, that is, the use power of the diesel generator set reaches 80% of the output power of the generator set

Control the fuel injection pump to ensure that the fuel supply of the fuel injection pump is not too large.

Control the oil in the governor to prevent the oil supply from increasing, otherwise it will all lead to the generator set"Flying cars"

In addition, we should attach great importance to the smoke phenomenon of the generator set, if the generator set emits twilight smoke or black smoke, these indicate that the diesel generator set is working abnormally and must be checked and dealt with in time. Only by keeping the diesel generator set in the best working condition can the purpose of fuel saving and fuel saving of the generator set be achieved, thereby reducing the cost of use and reducing environmental pollution.

Diesel generator fuel saver can be installed.

Diesel generator regulator method, the battery, ammeter are connected in series and connected to the battery binding post of the regulator. Start the engine and gradually increase the speed to observe the ammeter pointer on the tractor as the interceptor contacts are closed. If the pointer of the ammeter swings in the direction of "", it means that the closing voltage is high, and the spring tension should be weakened; If the ammeter pointer swings in the direction of " ", it means that the closing voltage is low and the spring tension should be increased.

In this way, the adjustment is repeated until the ammeter pointer hardly oscillates when the interceptor contact is closed, which means that the closing voltage is appropriate. The two batteries are connected in series with the battery and the ammeter and are connected to the battery binding post of the regulator. Start the engine and gradually increase the rpm.

While the regulator is in effect, observe the pointer of the ammeter. If the ammeter pointer swings in the direction of "", it means that the voltage regulation value is high, and the spring tension should be reduced; If the pointer of the ammeter swings in the direction of " ", it means that the voltage regulation value is low, and the spring tension should be increased. This is adjusted repeatedly until the regulator is in effect, and the ammeter pointer hardly oscillates, indicating that the voltage regulation value is appropriate.

The principle of this adjustment method is: the dry battery and the battery are connected in series, which has a certain potential, while the generator emits a certain voltage, and when the two are not equal, a current will be generated. If the potential of the former is higher than that of the latter, the ammeter pointer will be in the " " direction, and vice versa in the " " direction.

Only when the two potentials are almost equal will the ammeter pointer not swing.

Replace a solar generator.

A crank handle is fixed at the center of the circle, and the edge and center of the disc are respectively attached to a brass brush, and the brush is connected with the ammeter with a wire; The copper disc is placed in the magnetic field of a hoof-shaped magnet. When Faraday does not rotate the handle, causing the copper disc to rotate, the needle of the ammeter is deflected to one side, indicating that a continuing current has occurred in the circuit.

The disc can be seen as being made up of an infinite number of copper spokes equal in length to the radius, and when the disc is turned, each spoke makes a motion to cut through the magnetic field lines. The spokes and the ammeter in the outer circuit just form a closed circuit, and a current occurs in the circuit. As the disc rotates, a spoke reaches the direction where the magnetic line is cut, so that there is a continuous current in the external circuit.

as a flange connection;

The center of the rotating axis ensures function;

A well-designed disc can effectively help improve positioning accuracy and control against the balance of mental force;

Diesel generators have 5 major fuel-saving technical descriptions:

1. Install inertial supercharger: Installing and using inertial supercharger on diesel generator sets can generally increase power by 15% and reduce fuel consumption by 3% and 5%.

2. Oil return pipe diversion: connect the diesel engine oil return pipe to the high-pressure oil pipe, so that the oil return enters the low-pressure oil circuit, which can ensure normal combustion and the fuel-saving effect is very significant.

3. Wrap toilet paper on the filter element: Wrap 2 or 3 layers of toilet paper with strong adsorption on the diesel engine oil filter element, which can improve the cleanliness of the oil and reduce fuel consumption.

4. Install foam plastic air filter: In the two layers of air filter, add a layer of 8 20mm thick foam with good air permeability, which can improve the filtration effect, ensure the normal combustion of oil, and reduce fuel consumption.

5. Use the fuel-saving smoke reducer: fix the fuel-saving smoke reducer vertically in the front oil circuit of the fuel injection pump and connect it to the DC power supply. Used on diesel engine generator sets, the smoke reduction is significant. It not only reduces environmental pollution, but also saves about 5% of fuel.
