Vanguard® 24,6 Gross kW EFI/ETC
Features & Benefits
Specifications
The Vanguard® 24,6 Gross kW EFI/ETC horizontal shaft engine combines electronic precision and mechanical strength to power through the toughest jobs. Delivering 33 HP at 3600 RPM, this V-Twin engine is designed for heavy-duty construction, industrial, and agricultural applications. It integrates a closed-loop Electronic Fuel Injection (EFI) system and Electronic Throttle Control (ETC) to adapt fuel and throttle in real time—enhancing starting, load handling, and fuel efficiency. Engineered for long service life, it provides smooth operation, lower emissions, and extended runtime in demanding field conditions.
- Power for heavy-duty tasks: Strong torque and power from a compact, fuel-optimized V-Twin architecture.
- Smooth operator: Dynamically balanced internals minimize vibration and mechanical stress.
- Efficient power delivery: EFI and ETC systems ensure real-time fuel optimization and constant RPM across load variations.
- Durable design: Built to withstand high loads, thermal extremes, and daily operational stress.
- Compact Design
Designed to fit compact machinery without sacrificing power or durability—ideal for OEM flexibility in size-restricted environments. - V-Twin OHV Technology
Dual-cylinder layout enhances combustion efficiency, extending service life while reducing fuel use and emissions. - Smooth Easy Starting
Magnetron® ignition and mechanical compression release reduce cranking effort and ensure fast starts; solenoid shift and recoil options available. - Maximum Durability
Cast iron cylinder sleeves and reinforced block withstand mechanical wear while maintaining precise oil control in high-load conditions. - Electronic Fuel Injection (EFI)
Closed-loop EFI continuously adjusts fuel and spark based on sensor feedback—improving start-up, throttle response, and fuel efficiency by up to 25%*. - Electronic Fuel Injection with E-Governor
Electronic governor maintains RPM during fluctuating loads, allowing for stable performance across uneven terrain or varying system demands. - Superior Balance
Engine balance is maintained via lightweight pistons, ring package, and a dynamic crankshaft, reducing vibration and extending component lifespan. - High Efficiency Head Design
Angled intake/exhaust ports promote turbulence and air-fuel mixing for increased power, smoother idle, and cleaner emissions. - Extended Engine Life
Spin-on oil filter, full-pressure lubrication, and dual ball bearings protect critical components, increasing longevity and service intervals.
