The Zongshen ZS 182F(E) is a 0.3 L (338 cc, 20.63 cu·in) natural aspirated single-cylinder four-stroke air-cooled internal combustion small gasoline engine with a horizontal shaft, manufactured by Zongshen Power Co. for general-purpose applications.
The ZS 182F(E) engine has a single-cylinder, overhead valve (OHV) design, and recoil starter (182F) or electric starter (182FE). This engine used a carburetor fuel system, transistorized magneto ignition system, splash type lubricating system, and forced-air cooling system. The ZS 182F(E) is equipped with a 5.2 L (1.37 US. gal. 1.14 Imp. gal.) fuel tank.
The ZS 182F(E) engine produced 9.2 PS (6.8 kW; 9.1 HP) at 3,600 rpm of maximum horsepower and 20.1 N·m (2 kg·m, 14.8 ft·lb) of maximum torque.
