Global Generators

The short answer A diesel generator burns roughly 0.24 to 0.30 litres of fuel per kilowatt-hour of electricity it produces . Bigger sets sit at the efficient end of that range, small sets at the thirsty end, and every set gets less efficient the further it runs below its rating. For a quick estimate, take the generator's kVA rating, multiply by 0.8 to get kW, multiply by your load percentage, then multiply by 0.26. A 500 kVA set running at 75% load: 500 × 0.8 × 0.75 × 0.26 = about 78 litres per hour . The full chart below does that calculation for every common size we supply, from 10 kVA up to 3000 kVA. Full fuel consumption chart: litres per hour by kVA These figures are calculated at 0.8 power factor, which is the standard rating basis for three-phase generator sets. They include a part-load efficiency penalty, because a generator running at half load does not use half the fuel of one at full load.

 A diesel-electric generator is one of the most reliable ways to turn stored fuel into usable electricity on demand. It's the technology behind everything from construction site power to hospital backup systems — but the actual process of getting from a tank of diesel to a working power socket involves a few clear stages worth understanding. Step 1: Combustion. Diesel fuel is injected into the engine's cylinders and ignited under high compression, without the need for a spark plug. This combustion drives the pistons, which turn the engine's crankshaft — converting the chemical energy in the fuel into mechanical, rotational energy. Step 2: Mechanical to electrical conversion. The spinning crankshaft is directly coupled to an alternator. Inside the alternator, this rotation moves a magnetic field across copper windings, inducing an electrical current through electromagnetic induction. This is the exact point where mechanical energy becomes usable electricity. Step 3: R...
