did not seem reasonable the park lights were lit at three p.m.
And less knowing that it was not an oversight or a show of their occupants. It was not a test. It was a normal process. Day after day, year after year, the situation had been repetitive. Had begun long ago, having found that a generator of 27 Kw. 3 powered by a Perkins spent 3 liters of diesel fuel per hour in vacuum, with everything switched off and only one extra quart if you connected the lights, TV, computer and all appliances that they could think up to 1500 watts. It is easy to check. Just a drum, a clock and a balance to be convinced of the accuracy of that assertion. Wait until the engine warms up and the gas oil drum with pre-weighed and the feed and return hoses in the appropriate container to measure the cost of fuel taken for several minutes, say 15 to be exact .. Despite the balance, will make a difference and spending hours in grams. If you are interested in liters multiply by 1.20. Start with the
Specific Consumption - Maximum power 27 Kw motor-load consumption 2.5 kg / hour
specific consumption at 100% 230 g / Kwhora
group with everything switched off, in a vacuum. Repeat the test with a known load, for example 1000 watts, 10 lamps of 100 or 25 40 W fluorescent tubes Just these two checks to explain the rest. 5 hours per day, 18 to 23, is 15 liters per day just to satisfy itself of the Perkins place, necessary and essential accessories, such as the cooling system, the lubrication, the alternator, the friction of pistons, crankshaft, camshaft etc.
just 1.3 liters and have the electricity to supply the needs of each night. But understand that you need 15 liters of engine with or independent of to ask the electric generator is important to correctly analyze the causes of the exorbitant consumption and alternatives to things tidy . Ask the 27 Kw. , Ie the total power, only modifies the fuel needed by the alternator. 3 liters own engine will remain the same. But the engine manufacturer tells us that
full power consumes 7.44 liters (6.21 kg), of which 3 have already seen that uses the engine. The difference, 4.44 are those of the alternator has to be done over the 27 KW. electricity that we have requested. As is proportional, when he delivers a 50% load, 13.5 Kw. spend the usual 3 liters over 2.22, half of the 4.44, it is easy to guess that a fourth charge, 6.75 Kw, always will be the 3 most a quarter of the 4.44 and following the reasoning to any state of charge that comes to mind. For each additional hour will Kw 0.16 liters more. With this approach, we can make a spreadsheet, a graph, or both, as is what we have illustrated, and we have all the elements to optimize fuel consumption.
The first thing to justify is the why such a large group , If half, probably the 3 liters per hour would own 1.5 engine and it would saving 50%. Also the same charges would double their impact with which the performance
increase significantly. In short, less than half the fuel.
The second alternative is to increase consumption but not turning on lights at three in the afternoon but accumulated that energy to use it after the group stopped at 23 hours, and transform their annoying flashing uninterrupted service from that time until 18 the next day, giving us the ability to have a refrigerator, a freezer a bomb, or any device of automatic operation. The extra fuel cost is so insignificant that it is no exaggeration to say that it is free .. Over $ 1500 is the difference between a steer own dressing and kept in the freezer and it acquired in the carnage of the city and that benefit is in addition to fuel savings While all comments were made on the basis of a Perkins 3 is necessary to emphasize that the process is quite general and the same or similar results with other units arrive.
Note that typical for a rural self-supply, say between 1350 to 2700 watts The specific consumption ranges from 1063 to 1992 grams per kWhora, 3.62 to 7.66 times more than if the group was operating at full power. To complete this analysis, we recommend use of additional talks, "Consumption and oversized", "waste of fuel", "Consumption self and others" and "A wide open throttle."
