Honda EG1200X

Honda EG1200XThe Honda EG1200X is AC portable generator with 1.2 KVA of maximum power, 1.0 KVA of rated power and 50Hz of rated frequency. The EG1200X generator is available with AC 220V or 240V (depending on model) and rated voltage.

The Honda EG1200X generator is equipped with the GX120 K1 single-cylinder gasoline engine with 118 cm3, (7.2 cu·in) of displacement. The engine has an OHV (overhead valve) design, horizontal carburetor with butterfly valve, and transistorized magneto ignition system. The GX120 K1 engine’s compression ratio rating is 8.5:1, cylinder bore and piston stroke are 60.0 mm (2.4 in) and 42.0 mm (1.7 in), respectively.

The engine produced 3.9 PS (2.9 KW; 4.0 HP) at 4,000 rpm of maximum horsepower and 7.5 N·m (0.75 kg·m, 5.4 ft·lb) at 2,500 rpm of torque.

The Honda EG1200X generator with serial number GX110 1000001-9999999 uses the Honda GX110 engine. A 57.0 mm (2.24 in) cylinder bore and 42.0 mm (1.65 in) piston stroke give the GX110 engine a total of 107 cc of displacement. The compression ratio rating is 8.7:1. This engine produced 3.5 PS (2.6 kW; 3.5 HP) at 4,000 rpm of horsepower and 6.7 N·m (0.7 kg·m, 4.9 ft·lb) at 2,800 rpm of torque.
