The Kawasaki FX850V is a 0.85 l (852 cc, 51.99 cu-in) V-twin 90° air-cooled 4-stroke internal combustion small gasoline engine with vertical shaft, manufactured by Kawasaki Heavy Industries LTd., for general-purpose applications, commercial mowers, heavy-duty industrial and construction equipment.
The Kawasaki FX850V has V-twin design with vertical PTO shaft. The motor uses overhead V-valves; spherical combustion chamber; cast iron cylinder liners; metal engine cover with integrated clean out ports; rotating metal grass chopper screen. The engine is equipped with electronic spark ignition and twin barrel, internally vented carburetor with fuel shut-off solenoid. The FX850V motor uses a high-performance lubrication system with high-efficiency oil cooler and double or multi-stage canister air filter.
The engine has an automatic compression release (ACR) system with recoil or heavy-duty shift type starter. 13A or 20A charge coils, various speed control systems, oil pressure switches, and various oil drains are available as an option.
An 84.5 mm (3.33 in) cylinder bore and 76.0 mm (2.99 in) piston stroke give the motor a total of 852 cc (51.99 cu-in) of displacement. Compression ratio rating is 8.2:1. The Kawasaki FX850V engine produced 27.1 PS (19.9 kW; 26.6 HP) at 3,600 rpm or 27.3 PS (20.1 kW; 27.0 HP) at 3,600 rpm of maximum horsepower and 63.0 Nm (6.4 kg·m; 46.5 ft·lb) at 2,400 rpm or 60.5 Nm (6.2 kg·m; 44.6 ft·lb) at 2,400 rpm of torque.
