How to maintain the use of small gasoline generators(b)

Second, oil. Fuel and lubricants
1,
the fuel is generally used car with gasoline, because gasoline factory
and transportation process will produce glial and contain some other
impurities in the refueling tank port generally fitted with filters, but
in actual use, if the on the filter pad and then a two-tier medical gauze, filter better.
Because
gasoline explosive under certain conditions, to raise the gasoline
engine and the standby should be cooled before they can raise the fuel
in a well ventilated place down. Refueling non-smoking, open flames or sparks. Do not spill refueling tank (make sure there is no fuel filler), re-raise, make sure the fuel cap is closed. If refueling fuel spill, measures should be wiped clean, and make sure
that before starting the engine to make it dry and ventilated.
Top
general engine carburetor mounted a deputy oil needle, under mounted a
main needle by turning the needle into it to adjust the fuel and air
mixing ratio, needle screwed into less oil, the mixture thinning;
Unscrew the oil inlet more, the mixture thickens. The
mixing ratio is too lean, the engine speed instability; mixing ratio is
too strong, the cylinder exhaust smoke, engine speed slows down. When
adjusted to emphasize the main oil-pin, deputy oil after the transfer
needle, starting the first main oil needle spin out 3-4 laps, plus load
after screwed clockwise slowly until the engine speed and stability. If the voltmeter still above 5V and unstable, and the sub-needle spin
person, after slowly screwed, adjusted to the speed stable.
In
the gasoline engine combustion chamber of the combustion mixture, lean
requires a concentration range, in order to show the degree of
concentration of the mixed gas of lean, a represents a coefficient of
excess air used. That
is a :( excess air ratio of an actual air quantity L ÷ theoretical air
quantity L.), when the excess air ratio is greater than 1, the mixture
is lean, the concentration is less than 1, if greater than 1.4 or less
than 0.4, mixing the gas will not be ignited.
2,
lubricating oil: 4-stroke engine oil or the normal use of the United
States in line with SG, SF high-grade oil is recommended SAE1Ow3O oil,
suitable for use under various temperature conditions, check, clean
dipstick and then insert the filler neck, but do not spin in, if the oil level is too low, the recommended oil to the oil injection port. Another oil mixed oil grade should be selected depending on the season, usually used to HQ HQ1O a 15 motor oil. After
some time the use of lubricants, due to mechanical friction generated
dirt should be updated, the update should remember to join oil and
filling the oil dipstick measurement capacity.
