Why does diesel generate electricity? How to generate electricity with your own diesel engine

The diesel engine drives the generator to run, converting the energy of diesel into electricity. In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected by the fuel injector, and under the extrusion of the piston upward, the volume is reduced, and the temperature rises rapidly to reach the ignition point of the diesel. The diesel fuel is ignited, the gas mixture burns violently, and the volume expands rapidly, pushing the piston downward, which is called 'work'.

Each cylinder works in a certain order, and the thrust acting on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. The brushless synchronous alternator is coaxially installed with the crankshaft of the diesel engine, and the rotor of the generator can be driven by the rotation of the diesel engine. Diesel generator set is a type of AC power supply equipment of self-provided power station, which is a small independent power generation equipment that uses an internal combustion engine as a power to drive a synchronous alternator to generate electricity.

Modern diesel generator sets are composed of diesel engine, three-phase AC brushless synchronous generator, control box (screen), heat dissipation water tank, coupling, fuel tank, muffler and common base and other components. The flywheel shell of the diesel engine and the axial direction of the front end cover of the generator are directly connected by the convex shoulder positioning to form a whole, and the cylindrical elastic coupling is used to directly drive the rotation of the generator by the flywheel, and the connection mode is fixed together by the screw, so that the two are connected into a steel body, and the concentricity of the crankshaft of the diesel engine and the rotor of the generator is guaranteed to be within the specified range. In order to reduce the vibration of the unit, shock absorbers or rubber shock absorbers are usually installed at the connection between the main components such as diesel engines, generators, water tanks and electrical control boxes and the common base.

Diesel is just fuel, you're talking about diesel generators. Generators need power to generate electricity, so diesel generators are powered by diesel engines to generate electricity. Assuming that the power of the generator comes from the gasoline engine, then we can also simply call it a gasoline generator.

Gasoline is also available, but it is not as economical as diesel.

Dear, I'm glad to let you answer: Answer that you have a diesel engine so that the diesel engine drives the power generation liquid machine to generate electricity, and the generator is unable to generate electricity! 1.

The diesel generator realizes power generation mainly because the diesel fuel is burned in the diesel engine to do work, and the piston is driven to do reciprocating mechanical movement, the piston drives the crankshaft to run at high speed through the connecting rod, and the crankshaft then passes through the flywheel to transmit kinetic energy to the rotor of the diesel generator, so that the rotor cuts the magnetic field line and generates current. 2.The diesel generator set is composed of a diesel engine, a water tank, a three-phase AC synchronous generator, a starter generator, a battery and a battery cable, and a control panel.

A diesel engine is similar to a car engine and can be turned on instantly. Generally from start-up to power transmission, as long as.

One or two minutes. Diesel generator sets usually do not have a lot of power, have a simple structure, fast start, and are used in emergency power supply and emergency repair. Every building now uses a diesel generator set as a backup power 3

Only steam engines and steam turbines can burn water into steam in a boiler and then push the engine to work. In high-power thermal power plants, steam turbines are now used, which then drive the generators.

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. <>

Diesel power generation and coal power generation are two different ways of generating electricity, and they differ in the following ways:

1.Fuel type: Diesel power generation uses diesel as fuel, while coal power generation uses coal as fuel.

2.Combustion mode: Diesel power generation is to drive a generator to generate electricity by burning diesel in a diesel combustion chamber to produce high-temperature and high-pressure gases. Coal power generation is the generation of high-temperature and high-pressure steam through coal combustion, which drives steam turbines to generate electricity.

3.Emissions: Diesel power generation produces fewer pollutants from combustion than coal power generation, but diesel power generation emits higher levels of nitrogen oxides and particulate matter, while coal power generation emits higher levels of carbon dioxide, sulfur dioxide, nitrogen oxides and particulate matter.

4.Scope of application: Diesel power generation is suitable for some temporary or small-scale power generation needs, such as in areas far from the grid or when emergency backup power is required; Coal-fired power generation is suitable for large-scale grid power supply needs, because coal is a cheap and widely available fuel that can be used for long-term stable power production.

5.Cost: Diesel fuel is more expensive than coal fuel, so the cost of diesel power generation is relatively high. In addition, the maintenance and upkeep costs of diesel generators are also higher than those of coal-fired power plants.

The consequences of this situation are as follows: the former merge1. Diesel fuel will deteriorate: Diesel oil stored for a long time may deteriorate due to contact with air and moisture, and produce sediment, which will affect the cleanliness of diesel oil.

2. Sediment: long-term use of diesel oil will produce sediment, which will be firmly attached to the combustion chamber wall, resulting in oil leakage and leakage of the engine.

3. Lubrication system problems: The lubricating oil of the diesel engine will continue to circulate and circulate, and the long-term use of aging diesel will affect the lubrication system and aggravate the wear.

1. Power supply for daily use.

Although the power of diesel generator sets is low, it is widely used in mines, railways, field sites, road traffic maintenance, as well as factories, enterprises, hospitals and other departments because of its small size, flexibility, lightness, complete facilities, and easy operation and maintenance.

2. Emergency power supply.

Diesel generator sets are used where there is no connection to the grid, or as an emergency power source in the event of a grid failure, as well as for more complex applications such as peak tripping, grid support, and grid output.

Problem description: What does diesel combustion produce.

Dust? Sulfur dioxide? Or something else?

Analysis: Diesel is an organic substance mixed with organic compounds such as alkanes, aromatic hydrocarbons, alkyl limb benzene, naphthalene, indenides, etc.

Since there are hydrocarbons, there must be water generation after combustion, and the second thing is carbon dioxide.

Then there are some by-products, such as splitting nitrogen oxides, etc., in short, the products are very complex, and they are definitely not as simple as you think, such as sulfur dioxide and dust.

For related information, you can consult books on organic chemistry.

Diesel generator set is a type of equipment that uses diesel as fuel and diesel engine as the engine to drive the generator to generate electricity, and other types include gasoline, gas, wind, hydro, solar energy, nuclear fission and other forms of generator sets.

Generator sets typically have the following components:

Engine Motor. The main component of the generator set, it runs on fuel. A good engine is strong enough to meet the needs and functions of adverse conditions (i.e., bad weather).

Alternator. This component converts mechanical energy into electrical energy; Without it, there is no power.

Control panel. It acts as the "brain" of the generator set, controlling and regulating all other components.

Fuel system. This component consists of a tank and hoses that deliver fuel to the engine.

Voltage regulators. This controls the amount of voltage generated by the genset and converts the A C current to the D C current.

Chassis housing. The foundation frame supports the generator and holds the components together. It can also be used as a shock and grounding system and may or may not accommodate a fuel tank. It can be mounted on wheels to make it portable.

Pull the rope mechanism or battery. An initial spark is required to start the combustion process of the portable generator. This usually happens via a cable pull mechanism, such as a lawn mower, or a starter motor powered by a DC battery.

Manual or automatic transfer switches. The transfer switch directs the power supply between the main power supply (utility power) and the auxiliary power supply (generator). This keeps the current consistent and prevents dangerous interruptions.

Baffle box or enclosure. The vessel is typically made of stainless steel, which reduces noise, prevents corrosion, and promotes airflow to cool the engine.

Generators don't require intensive maintenance, but it's important to understand their internal mechanisms. This allows you to perform preventative and general maintenance as needed, while knowing how to order replacement parts.

What are the types of generator sets?

Generators come in different sizes and can run on different fuels**. Here are the different generator fuel systems, including the pros and cons of each.

Gasoline generators.

Gasoline generators are the most popular option because gasoline is readily available. The ** of the gas generator set is also very low and very portable.

However, gas generator sets can be used for a short period of time and are inefficient in fuel. Gasoline can be kept in storage for about a year. But it is also highly flammable and can be dangerous in certain environments.

Diesel generators.

Diesel engines are more powerful than gasoline engines. Diesel fuel is also less flammable, and its availability is very common. With proper maintenance, diesel generator sets can last for a long time.

The main disadvantage is that diesel can only last for about two years, and it can become expensive to use in large quantities. Diesel engines also produce significant emissions.

Biodiesel generators.

Biodiesel fuel is a mixture of diesel and other bio**, such as animal fat or vegetable oil. Because it emits less oil when burned, it's more environmentally friendly, produces less waste, and has a smaller fossil fuel footprint.
