Vanguard® 27,6 Gross kW EFI/ETC
Features & Benefits
Specifications
The Vanguard® 27,6 Gross kW EFI/ETC horizontal shaft BIG BLOCK™ engine delivers peak performance for high-power applications in agriculture, construction, and industrial equipment. Producing 37 HP at 3600 RPM, this engine integrates advanced Electronic Fuel Injection (EFI) and Electronic Throttle Control (ETC) technologies, delivering real-time optimization of fuel delivery and throttle response. With reduced vibration, consistent RPM under heavy load, and extended runtimes, it’s the ideal choice for machines that demand powerful, fuel-efficient performance in challenging environments.
- Power for heavy-duty tasks: High-displacement V-Twin delivers robust torque and horsepower to support intensive commercial machinery.
- Smooth operator: Balanced internal components reduce vibration, enhancing operational stability and user comfort.
- Efficient power delivery: Closed-loop EFI and instant-response ETC provide consistent RPM, fuel savings, and improved throttle handling.
- Durable design: Built for rugged reliability, this engine maintains efficiency and performance under constant stress.
- Improved Sound Quality
Resin blower housing and phase-modulated flywheel fan deliver a quieter, more refined engine tone for better operator experience. - V-Twin OHV Technology
Overhead valve configuration increases power and efficiency, while the V-Twin layout ensures smooth and balanced operation. - Smooth Easy Starting
Mechanical compression release and Magnetron® ignition ensure quick starts. Solenoid shift and rewind start options are available. - Maximum Durability
Cast iron sleeve and reinforced block resist wear and provide reliable oil control, even under continuous high-load conditions. - Cyclonic Air Cleaner
Five-inch cyclonic system filters airborne debris to protect internal components, extending air cleaner service life. - Electronic Fuel Injection (EFI)
Closed-loop EFI system automatically adjusts fuel and spark for easier starting, optimized performance, and up to 25% fuel savings.* - Electronic Throttle Control (ETC)
ETC reacts to load changes in real time, maintaining RPM stability via flywheel speed sensors and electronic throttle adjustments. - Extended Engine Life
Dual ball bearings and full-pressure lubrication with a spin-on filter provide long-term protection for moving parts. - Superior Balance
Balanced crankshaft and lightweight piston assembly minimize vibration and enhance thermal durability. - High Efficiency Head Design
Angled ports improve combustion efficiency and fuel mixing for reduced emissions, better idle, and more consistent output.
