Diesel Generators VS Gasoline Generators
The generator is a mechanical device that converts other forms of energy into electric energy. Driven by a water turbine, steam turbine, diesel engine or other power machinery, it converts the energy generated by water, air, fuel combustion or nuclear fission into mechanical energy and passes it to a generator, which then converts it into electric energy. Among them, gasoline generators and diesel generators are most commonly used in construction sites. While there are many differences between gasoline and diesel generators, both are efficient for the task at hand. Do you know the difference between them? If you’re interested, read on.
Firstly, how does a gasoline generator work? In simple terms, a gasoline engine drives a generator and converts energy from gasoline into electricity. In the cylinder of a gasoline engine, the violently burning gas mixture rapidly expands the volume and pushes the piston downward for work. Each cylinder works in a certain sequence, and the thrust force acting on the piston becomes the force pushing the crankshaft through the connecting rod, thus driving the crankshaft to rotate. When a synchronous alternator is installed coaxially with the crankshaft of a gasoline engine, the rotor of the generator can be turned by the rotation of the gasoline engine. This electromagnetic induction ’causes the generator to output the induced electromotive force, which generates current through the closed load loop.
Diesel generators are different. It is operated by a diesel engine that drives a generator and converts diesel energy into electricity. In the diesel cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected by the nozzle, and the volume shrinks under the upward extrusion of the piston, and the temperature rises rapidly to the ignition point of the diesel. Diesel is ignited, the mixture of gas intense combustion, and rapid volume expansion, push the piston down, known as’ work ‘. Each cylinder does work in a certain sequence. The thrust force acting on the piston drives the crankshaft through the connecting rod to rotate, thus driving the crankshaft to rotate.
After a brief look at how they work, we know diesel generators ignite their fuel by compressing the air around the fuel. The compression ratio of a diesel engine is more than double that of a gasoline one, so the fuel is much safer and less flammable. This makes it an ideal choice for infrequent or low-load applications, as it will produce less noise and smelly emissions. Other differences include:
Potenza in uscita
Fuel efficiency is another key difference between gasoline and diesel generators. Although both types of fuel require higher fuel consumption, diesel generators burn fuel more efficiently and can run for much longer than gasoline generators. The output power of a diesel generator is much greater than that of a gasoline generator set. The power of a common gasoline generator set is only 10KW versus 8KW for diesel generators.
Volume and noise
The gasoline generator set is smaller and more portable, mainly air-cooled, and generally small in power. The diesel generator set is mainly water-cooled, a large volume and loud noise. But unlike decades ago, today’s diesel generators are quieter than their gasoline counterparts.
A gasoline generator will be quieter than a diesel one, which makes it ideal for construction sites and other close quarters. Generally speaking, gasoline generators are small and easy to move, and are generally used in small construction sites; Diesel engine volume is not easy to move, but a larger power and more suitable for large-scale construction site.
While gasoline generators are generally more affordable, diesels are much more fuel-efficient. Fuel consumption is typically around 7 percent of the rated generator’s output. Diesel generators typically cost 30 to 50 percent less per kilowatt than gasoline generators. The running time of diesel generators during routine maintenance and maintenance is 2-3 times longer than that of gasoline generators of the same type. The 1800rpm diesel generator set has a service life of up to 30,000 hours, compared to 10,000 hours for gasoline. The working temperature of gasoline generator set is higher than that of diesel generator set, which greatly prolongs the working life of diesel generator set.
Diesel generators typically require less maintenance than gasoline generators, and are less flammable than gasoline. And the absence of electronic ignition means fewer errors and less downtime. This means they are better for off-grid applications. Because they require less fuel, they can last much longer.
Which is better? Diesel Generators or Gasoline Generators
Despite these differences, petrol generators are the more affordable option, particularly if you are using them infrequently or for temporary use. They are also cheaper, and there is a wide range of models and price ranges to choose from. However, they do have fewer features and power than diesel generators. Diesel generators are more reliable than gasoline generators, so they are an excellent choice if you need uninterrupted power for your home. Furthermore, the fuel used in a diesel generator is less flammable than gasoline, making it an excellent choice for companies that handle chemicals and other combustible products. In short, diesel generators or gasoline generators, that’s depends on your choice and applications.
