Common Applications
  • Pressure washers
  • Generators
  • Forestry equipment
  • Construction / industrial equipment
  • Agricultural equipment
  • Water pumps
  • Small Engines
Advanced Technology
  • Integrated ECU (electronic control unit) with a self-tuning regulator (STR) governor system.
  • Engine senses and adjusts RPMs to match the application's load and speed requirements.
  • ECU enables drive-by-wire remote control operation of the engine and regulates functions such as throttle position.
Fuel Efficient Operation
  • Fuel economy is increased by approximately 15% over a similar conventional engine
  • Auto Throttle
High Power Output
  • Electronic governor minimizes governor droop, increasing available power
  • Allows the engine to respond significantly faster to the load
Smooth Performance
  • ECU fine tunes the throttle position to maintain a precise engine speed.
  • Precision engineered components result in lower vibration
Exceptionally Quiet
  • Improved muffler reduces overall engine noise by up to 4 dB(A).
  • Large capacity, multi-chamber exhaust system
  • Reduced mechanical noise due to higher compression and piston design
  • Forged steel crankshaft and rigid crankcase
