Honda EG2500X

Honda EG2500XThe Honda EG2500X is AC/DC portable generator with 2.5 KVA or 2.2 KVA of maximum power, 2.3 KVA or 2.0 KVA (depending on model) of rated power and 50Hz or 60Hz of rated frequency. The EG2500X generator is available with AC 120V, 220V (depending on model) and DC 12V rated voltage. The direct current terminals can be used for charging 12-volt automotive-type batteries only up to 8.3A.

The Honda EG2500X generator is equipped with the GX160 K1 single-cylinder gasoline engine with 163 cm3, (9.9 cu·in) of displacement. The engine has an OHV (overhead valve) design, horizontal carburetor with butterfly valve, and transistorized magneto ignition system. The GX160 K1 engine’s compression ratio rating is 8.5:1, cylinder bore and piston stroke are 68.0 mm (2.7 in) and 45.0 mm (1.8 in), respectively.

The engine produced 6.0 PS (4.4 KW; 6.0 HP) at 4,000 rpm of maximum horsepower and 11 N·m (1.1 kg·m, 8.0 ft·lb) at 2,500 rpm of torque.

The Honda EG2500X generator with serial number GX140 1000001-9999999 uses the Honda GX140 engine. The cylinder bore is 64.0 mm (2.52 in) and the piston stroke is 45.0 mm (1.77 in). The compression ratio rating is 8.7:1.

The Honda GX140 engine produced 5.0 PS (3.6 kW; 4.8 HP) at 4,000 rpm of maximum output power and 9.8 N·m (1 kg·m, 7.2 ft·lb) at 2,800 rpm of peak torque.
