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.
