ELECTRONIC FUEL INJECTION (EFI)
& ELECTRONIC THROTTLE CONTROL (ETC)
SMOOTH, CONSISTENT PERFORMANCE. REDUCED CONSUMPTION
Vanguard's Electronic Fuel Injection (EFI) uses the Engine Control Module to fine-tune the engine's performance. It processes sensor signals to optimize fuel and spark for each cycle, ensuring improved starting in all temperatures, smooth performance at any elevation, quick load response, and reduced fuel consumption.
Vanguard's Electronic Throttle Control (ETC) technologyinstantly reacts to applied loads, ensuring smooth, consistent power in any condition. The flywheel speed sensor detects RPM changes and signals the throttle body to maintain stable engine speed, delivering reliable performance across all terrains and loads.
REDUCED OPERATING COSTS
Our Vanguard V-Twin EFI engines feature an automotive-based, closed-loop EFI system that delivers easier starting and improved performance, with fuel savings of up to 25%*.
*Closed-loop EFI system fuel savings may vary based on cutting conditions and other factors. EFI engines compared to Vanguard Carburetor engines.
