First of all, new and old diesel generator power unit, its fuel consumption is not the same. The new turbine generator fuel consumption fuel consumption is much lower. Because the old machine used for a long time, wear and increase fuel consumption will of course increase. If used for long time after consumption the cost of oil can reach to buy new generating unit cost.
Secondly, diesel generating sets of new and old generating units in the warranty is not the same. The new is the whole year warranty, no matter which part of the quality problem, all can guarantee. And the old generation, although some second-hand business will be promised warranty, but the specific warranty will be all sorts of problems, some can not be repaired, even the machine is not used, but more waste.
