Kawasaki FA76D

Kawasaki FA76DThe Kawasaki FA76D is a 76 cc, (4.64 cu·in) natural aspirated single-cylinder four-stroke air-cooled internal combustion small gasoline engine with a horizontal shaft, manufactured by Kawasaki Heavy Industries LTd. for general-purpose applications.

A 52.0 mm (2.05 in) cylinder bore and 36.0 mm (1.42 in) piston stroke give the FA76D engine a total of 76 cc of displacement. The compression ratio rating is 6.4:1.

The FA76D engine produced 1.7 PS (1.25 kW; 1.7 HP) at 4,000 rpm of maximum horsepower and 3.1 N·m (0.3 kg·m, 2.3 ft·lb) at 3,200 rpm of maximum torque.

The Kawasaki FA76D features:

  • One piece hypereutectic aluminum-silicon alloy die casting with plateau honing cylinder and crankcase
  • Hard-chrome plated aluminum alloy piston
  • Two compression rings including silicon carbide (on an iron base) plated top ring, and one oil control ring
  • I-beam cross section, heat treated aluminum alloy connecting rod, with large bearings
  • Heat treated ductile iron crankshaft, integrated with counterbalance weights and camshaft drive gear
  • Forged 21-4N austenitic stainless steel exhaust valve and forged heat-resisting steel intake valve
  • Magneto ignition with waterproof molded ignition coil. Breaker system standard or electronic ignition system (optional)
  • Pulse pump carburetor or float carburetor
  • Mechanical fly-weight typel governor
  • Splash type lubrication system
  • Forced air cooling system with large capacity, curved vane blower casting, integrated with flywheel
  • Recoil starter
