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
- Auto Throttle
- Fuel economy is increased by approximately 15% over a similar conventional engine
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 camshaft and muffler to reduce overall engine noise by up to 5 dB(A).
- Large capacity, multi-chamber exhaust system
- Reduced mechanical noise due to higher compression and piston design
- Forged steel crankshaft and rigid crankcase
Proven Reliability
- Long-life air filter
- Multifunction Oil Alert
