It's OK Nigel.....no one's ego is involved here.....someone comes onto this site and asks a simple question to which there have been replies....and fair enough.
But it seems there is always a knocker out there for everything who gives a negative report....no matter....that's the nature of this site.
Of course no one minds if the
information is correct.
But back to the running of gennies.....glazing is NOT restricted to gennies alone or to one particular brand, it happens to all motors if they are run for long periodsand are not loaded.
Take for example some remote power supplies that are running spinning
reserves for long periods...for example 80 mile beach caravan park WA...overnight. Many hours and hardly any load.
Now for the normal user like Kiwibound, he might use his perhaps, like me,would start it at say 5pm and it will run to about 9 pm at the latest ( 4 hours) and because he's tired and shuts it down to put it away before he goes to sleep.
I run the microwave a bit and mostly the TV and laptop and a few lights and the onboard battery chargers as
well....so it's up and down as the load varies, never constant.
So far it is working just fine, uses no oil and a bit of fuel, always starts and no power issues. This is the reason I promote the Honda 20i...it is mid range, not too big, not to oversize in KVA and kind to old backs that are nearly stuffed.
So the Honda 20i has to work a bit.
Most of the time glazing is associated with oversizing where the motor does not have to work hard.
Where I work we have lots of lighting plants, of varying sizes, that run at a constant 1500 RPM to give us 50 HZ, and on some of them, glazing was an issue, because the prime mover (motor) too large for the load and so the motor never worked hard enough.
The result was we had to downsize the diesel engines from a 4 cylinder to a 3 cylinder. (They are a air cooled DEUTZ)
Now we are getting longer runs out of them....but as you can see it happens to ALL of them if they are not loaded, that's why it pays not to get one that is too big.
I also want to add with the
mine site ones, they dont fail with cylinder glazing but because of timing belt breakages, oil pump failures, fuel pumps and injectors......not cylinder glazing.
