  • Hello, something other than microcontrollers this time. I decided to test two 1800W 'suitcase' generators from both ends of the price range.
    A Honda at around £6000 and an AIVOLT at £1099. Honda purchased in early 2020. AIVOLT this month.

    Testing the Honda EU22i generator in a garden setting. AIVOLT SC2300i-0 generator, oscilloscope, and heater on paving stones.

    HONDA EU22i:
    Weight without fuel: 21.1 kg.
    Fuel tank capacity: 3,6 l.
    Engine capacity (GXR120T): 121 cm3.
    Rated power: 1.8 kW.
    Instantaneous power: 2.2 kW.




    .

    Easy access to the oil or carburettor. All you need is a 5 penny coin.

    AIVOLT SC2300i-0:
    Weight without fuel: 19.7 kg.
    Fuel tank capacity: 4 l.
    Engine capacity (SENCI SC80): 79 cm3.
    Rated power: 1.8 kW.
    Instantaneous power: 1,9 kW.

    To remove the carburettor I think you have to unscrew the whole housing. Without this, the fuel tank gets in the way.
    If you are stubborn, you can get to the main nozzle as if something is blocked. You have to unscrew the air intake tube from the filter. This thin black tube can be slid out of the thick one.
    After removing the tubes from underneath, you can unscrew the carburettor bowl. The nozzle will be screwed in from the side.
    Nozzle #70, 4mm diameter.

    Load: 700W / 1200W / 1900W heater.
    Fuel: E10, 95 octane
    Oil: 10W30
    Due to the lack of a 100x probe, I connected the oscilloscope via a 100:1 transformer (I unwound some coils).

    I've used both generators a few times with the lawnmower (hehe, I know) and had no problems.

    Noise level: .
    It's an internal combustion engine in a suitcase, don't expect miracles.
    It's impossible to sleep next to them (despite the seller's marketing images).

    Plus/minuses:
    Honda:
    + works as required
    + you can turn off the fuel without extinguishing the engine
    + easy access to the carburettor
    - price

    AIVOLT:
    + price
    + suction/on/off knob
    - it is not possible to turn off the fuel with this knob without extinguishing the engine
    - difficult access to carburettor
    - no fuse on the panel (maybe there is an electronic one)

    Problems: .
    I have no major complaints about the Honda.
    This year I cleaned the carburettor because my revs were floating (nozzle clogged).

    As far as the AIVOLT is concerned:
    - it smokes a bit when accelerating, smells of petrol
    - plug goes black after 90 minutes of operation
    - slightly rough running
    - one of the screws on the starter side cannot be unscrewed, it looks as if the nut is rotating
    - After reporting the problem to the dealer/service agent, he says it is just as it should be

    Can you say something about the burn rate, did you measure consumption, so pi times eye?

    I understand the AIVOLT is new, and how many rbh's does Honda have on its CV?

    I measured the Honda immediately after purchase. I think it was something around 0.5l / hour at low load.
    I didn't check the AIVOLT. It's hard to get to the fuel hose in it.

    Honda used with various power tools on the allotment. Probably something in the region of 10 hours.
    Major power outage hasn't happened yet to hook up the fridge or something.

    I bought the AIVOLT for tools (mower, washer...) with which I don't want to tire the Honda.

    I have one more question, what are these waveforms? Is it the same as the sine wave from the earlier oscillograms, only a larger time interval is included and the moment of change of the genset inverter load is captured?

    .
    Exactly. Two versions with different compression. I have posted so that you can see how big and how long the drop is.
    For the voltage measured by the oscilloscope on these compressed waveforms, pay no attention. I forgot to switch off.

    This Aivolt is somehow too dark, either it takes oil or the carburettor is badly adjusted for a 4T engine. The 80 ccm engine is rather a dedicated piece of equipment for a small obcìążenia. I wonder if Loncin hasn't already copied the Honda generator?

    I have not noticed any oil loss so far. Oil colour OK too.
    It seems to me that rather petrol smells too much.
    I've tried with smaller jets, without load it stops kicking, with load the revs float a lot.

    Have you tried changing the spark plug to a branded one, such as a Denso?
    I in a Chinese (branded Stanley with an inverter) replaced the original spark plug with a Denso and it's a completely different unit operation. It ignites more easily and runs more evenly.

    Something for something.
    You buy a Honda original and have virtually no problems. You only change the oil and check the air filter and spark plug every now and then.
    Buy a Chinese one and you have some problems right from the start. If you find one, the carburettor should be replaced at the beginning, because the engine doesn't work properly, it floods or stops, the carburettor is wrong for the engine. You don't know how long the engine will last, or whether the alternator or inverter will burn out. Power quality under load out of the norm - high content of higher harmonics.
    As you can see, plug black which means running on a rich mixture. Oil dilutes with petrol, which accelerates wear. Oil is already leaking from the exhaust. If it blows the exhaust with soot, the engine starts to choke.
    I would still pay attention to whether the mufflers are fitted with a catalytic converter.

    It's not that bad. It's still a long way from AVR-free 2-strokes. Those should be banned.
    I'm considering whether to test something like this.

    It could have drawn oil when it was transmitted in a recumbent position. As they say, price works wonders and in the case of the honda this is hardly attractive by Polish standards. At one time there was a rash of counterfeit honda generators of slightly higher power, which were of poor quality but highly polished in appearance difficult to distinguish for the layman.

    They had a Honda clone in Castorama a while ago. The look was the same, just the name was different.

    Changing the spark plug will do little if the carburettor is badly tuned and the engine is fed too rich a mixture.
    Probably this ch* brand carburettor doesn't even have an idle mixture adjustment screw, so nothing else will do with it. The only thing you can do is replace it with some better carburettor with normal adjustment, or with a carburettor from a genset that is correctly tuned.
    I replaced the carburettor on a 2T power unit. Although it was clean, it behaved as if it was not getting fuel into the idle system, the engine would stall or the revs would wave. I bought a second one for probably £30 from an allegro, probably made of cast aluminium because it was extremely light, but it worked straight away and you could adjust the idle mixture and the free revs. It was puffing along nicely.
    2T gensets, the fact that they are not suitable for powering electronics (no AVR stabilisation) but only for basic electrical appliances, have quite weak generators of about 800 watts. Use a 1:50 mix, not 1:40 or 1:33 as the Chinese recommend.
    For lower power devices I have an old APC UPS that runs without being connected to the mains. Such a little powerbank for 230 volts. The voltage is a stepped approximation, but that doesn't make it much of a problem.

    I know the Honda is a notch more expensive, but it seems to me that it will outlive the AIVOLT and double that.
    Plus the Honda has easier access to parts that need to be serviced from time to time.

    In addition, the Honda has the option of synchronised operation, which is a huge plus, e.g. for transmission trucks.

    Not necessarily loud. There are silenced gensets. The fact is that you are unlikely to get a genset with an original engine, only with a Chinese fake Yanmar, and strange things happen with them. Besides, they are already expensive.
    As for the Volt, probably the only solution will be to buy a second carburettor, fitting from another genset with a similar engine.

Topic summary

A user conducted a comparative test of two 1800W suitcase generators: the Honda EU22i and the AIVOLT model. The Honda, purchased in early 2020 for approximately £6000, has a fuel consumption of about 0.5 liters per hour at low load and has been used for around 10 hours with various power tools. The AIVOLT, acquired recently for £1099, has not been tested for fuel consumption yet. Discussion points include the Honda's reliability, ease of maintenance, and superior power quality, while concerns were raised about the AIVOLT's performance, including potential carburetor issues and rich fuel mixture. Participants suggested that the AIVOLT may require a carburetor replacement for optimal performance. The Honda's design allows for easier access to maintenance components, and it offers synchronized operation capabilities, which are beneficial for certain applications.
