The Honda EN2000 generator is equipped with the GC160 single-cylinder gasoline engine with 160 cm3, (9.8 cu·in) of displacement. The engine has an OHC (overhead camshaft) design, horizontal carburetor with butterfly valve, and transistorized magneto ignition system. A 64 mm (2.5 in) cylinder bore and 50 mm (2.0 in) piston stroke give the engine a total of 160 cc of displacement. The compression ratio is 8.5:1.
The engine produced 5.0 PS (3.7 KW; 5.0 HP) at 3,600 rpm of maximum horsepower and 10.3 N·m (1.05 kg·m, 7.6 ft·lb) at 2,500 rpm of torque.
