    Portable Diesel Generator Working principle


    In short, the portable diesel generator drives the generator to run. In the cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel fuel injected by the fuel injector. Under the upward extrusion of the piston, the volume is reduced and the temperature rises rapidly, reaching the ignition point of the diesel. The diesel is ignited, the mixed gas burns violently, the volume expands rapidly, and the piston is pushed down, which is called work. Each cylinder performs work in a certain order, and the thrust on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. By installing the brushless synchronous alternator and the crankshaft of the diesel generator coaxially, the rotor of the generator can be driven by the rotation of the diesel generator and then using the principle of electromagnetic induction, the generator will output the induced electromotive force, and the closed load loop will generate current.

    Only the most basic working principle of the silent diesel generator set is described here. A series of diesel generators and generator controls, protection devices and circuits are also required to obtain a usable, stable power output.

    Silent Diesel Generator for Home


    As we all know, fuel cost and availability, durability, safety, low maintenance and reliability directly affect the daily life of generators, therefore, the ATO portable diesel generator has the following advantages:

    • More energy saving and fuel-saving:  Diesel is known for its fuel efficiency. Diesel generators burn half as much fuel as natural gas generators yet deliver the same power, making them a great choice for any industrial project.
    • Safer:  Safety is always the number one factor when using generators on construction sites or at home. Diesel is a safer fuel to store and use.
    • Lower maintenance and maintenance requirements:  One of the benefits of diesel generators is their low maintenance costs. The portable diesel generators do not use spark plugs or carburetors, which means fewer moving parts to replace or fix without extensive maintenance and servicing.
    • More durable:  In addition to low maintenance, silent diesel generators have the advantage of being used longer. With proper care and proper use, it can withstand heavy daily use and will last for many years.
    • Provide a more reliable power supply:  Whether you are using a silent diesel generator for home use or a construction site/business, it can provide reliable power.

    Why Three Phase Diesel Generator Loses Phase?


    A three-phase diesel generator is a new type of power generation equipment, with a lightweight design, reliable quality and a wide range of applications. Many customers feedback that the three-phase diesel generator sometimes lacks motor phase during its use. What is the reason for the phenomenon?

    The reason for the phase loss of the three-phase diesel generator motor is that the power supply line (usually a contactor or a circuit breaker) does not supply the three-phase voltage to the motor at the same time, or the line is disconnected. The phenomenon is that if the motor can rotate at no-load, it will instantly heat up and hum and the rotation will be weak; when it is overloaded, it will just hum and instantly heat up. If the power is not turned off in time, the motor will be burned.

    For a three-phase induction motor, the normal operation should be three proportional AC currents flow into the three proportional stator windings to produce a circular rotating magnetic field. When the three-phase current is missing one phase, the motor will appear an abnormal operation phenomenon. The main reasons for the engine to cause a phase failure are the following situations.

    Gasoline vs. Diesel Generators


    3 kW (3.5 kVA) to 10 kW (12.5kVA) portable diesel generators are also ideal for industrial use when there is a power outage or power shortage. It should be noted that, for efficiency and safety, a diesel generator of suitable power must be used.

    Natural gas generators are another ideal option for emergency use. One of the reasons natural gas generators are some of the best is that they don't need to be ready to store gas to get electricity, just have piped gas and that's it. Of all the non-renewable resources available for power generation, natural gas generators is one of the most efficient sources of power.

    When an emergency actually occurs, portable diesel generators can provide a reliable and stable power supply for enterprises. However, for some large enterprises, factories, construction sites, hospitals, computer data centers, financial institutions and other industries that require a more reliable power supply, a silent diesel generator is the ideal choice.
