THIS WILL MAKE YOU AND YOUR GENERATOR HAPPIER
Energy from Gas
Some months ago, I used to watch some videos on Youtube
about certain people running petrol generators on cooking gas using a specially
designed carburetor which could handle both petrol and gas combustion. I got
one out of curiosity and have been using it without issues.
The first question I get asked by people who have not heard
or seen this is “how long a 12.5kg of gas would last (in days)?” In order to
get the answer to this question without complicating things for the listener is
to do a comparison between gas and petrol use.
Let us consider these three points:
1.
Tuning
2.
Servicing and maintenance
3.
Engine life.
Tuning
The term tuning when it comes to engines would strike one as
adjustments made for performance or fuel economy. When using petrol for your
generator for instance, how long would you normally run it assuming you had 10
litres of petrol in it? Some people run their generators only at night, say
from 8pm to 11pm; while others could run theirs in the day either for
entertainment or as a result of the hot weather. In such cases, the runtime
could get up to 6 hours or more. One of my neighbours shuts his only when he is
out of petrol. After considering this, ask the question again and see how
difficult it has turned. The best approach to get the answer to such a question
is by conducting experiments. If we run the generator for a period of 4 hours
daily, what then becomes the consumption rate and how long would the fuel last?
This is the factor that proves whether the generator is economical or wasteful.
Using petrol, I learnt a trick which involved lowering the
RPM in relation to the load.
Manufacturers usually keep it high just for best performance. Therefore if the
air conditioner is not going to be powered on, why run the generator at high
performance.
Opening the fuel valve half way helps to cut down the quantity
of petrol flowing down the tank to the carburetor. Thus a combination of both
could save a lot on petrol expenses
Coming back to the use of gas, I tried the same old trick
and found out that it also did help in reducing gas consumption but overtuning
for economy caused hard starting.
Gas has a fixed price compared to petrol which continually
changes. After a series of experiments, I discovered that gas lasted longer
than petrol of the same price.
We all need a cheap fuel in order to generate a reliable
source of electricity.
Servicing & Maintenance
When using petrol
for your generator, carbon builds up over time in the engine especially in the
areas that handle combustion and exhaust. For instance, when you check the
piston and rings, the engine block and exhaust, you will find a lot of carbon
deposits which is difficult to remove for something of a week’s use.
The same cannot be
said about a gas operated engine because it involves gaseous fuel and not
liquid. Gas because of its state, creates less carbon deposits in the engine. Even
after a month’s use, you are sure not to find any carbon hard enough to disturb
engine performance. This by far could keep your generator free from engine
servicing for up to a period of 6 months hence reducing servicing costs.
However, oil change should be done at least
once in a month and checks for leakages should be carried on on a routine
basis.
ENGINE LIFE
It is difficult and
expensive to buy original spare parts. As more engine repair/servicing is
carried out on your generator, with parts being replaced by inferior ones, the
life of the generator slowly comes to an end. Using gas which requires less
servicing, helps to prolong its life.
THE
OVERALL BENEFITS
Converting your
generator to use dual fuel which requires a special carburetor, gas hose, cylinder
and regulator, could be quite expensive at the initial stage but all expenses
could be recouped in the form of fuel economy and service free use.
