Briggs & Stratton expanded its lineup of Vanguard EFI offerings to include a horizontal-shaft Small Block v-twin engine. The Small Block engine features an open-loop EFI system with e-governing engineered for the demands of the commercial construction and rental markets. The Small Block system delivers fuel based on operator throttle inputs. This shifts the system’s primary benefits to power delivery and throttle response, making it ideal for generators and general purpose equipment.
The electronic governing system optimizes usable power while providing more responsive and efficient delivery. The e-governing also improves shock load acceptance and speed control.
The Vanguard EFI engines feature a battery-less backup recoil start for ultimate reliability, even if the battery is dead. The recoil start uses energy generated by the recoil system to power the engine control unit and fuel system. Additionally, the open-loop EFI system is calibrated for automatic altitude compensation.
