Vanguard 400 EFI/ETC

The Vanguard 400 EFI/ETC engine brings together Electronic Fuel Injection (EFI) and Electronic Throttle Control (ETC) to deliver intelligent power and unmatched fuel efficiency across a wide range of applications. The EFI system continuously optimizes fuel and spark delivery for consistent output and better cold-start performance, while ETC maintains constant RPM under load shifts—ensuring smooth operation across tough terrain and extreme weather. This advanced engine system minimizes environmental impact, extends service intervals, and reduces operational costs. Backed by a 3+1 year warranty, it’s a reliable, future-focused upgrade for professional-grade equipment.

  • Lower noise. Less vibration. Increased user comfort: Enhanced engine balance and design provide quieter, smoother operation for all-day use.
  • Low TCO, reduced consumption: EFI and ETC technology extend oil and air filter intervals, maximizing uptime and reducing fuel and service costs.
  • Ideal for simple replacement: Drop-fit compatibility with common engine platforms for fast integration and repowering.
Features & Benefits
  • Simplified 3-Step Starting
    Cold-weather ready, this engine starts quickly and with less effort thanks to an optimized 3-step recoil system—tested down to -29°C.
  • Eliminate Fuel/Oil Dilution
    TransportGuardâ„¢ 3-in-1 system prevents fuel and oil mixing during transport by shutting off ignition and fuel together, reducing unnecessary downtime.
  • Optimized Fuel Management
    Advanced EFI and refined fuel system provide resistance to stale fuel and maintain readiness during long idle periods or variable climates.
  • Outperforms in All Terrains
    Optional High Inclination Package supports continuous operation on slopes up to 45° in any direction—ideal for rugged, off-road equipment.
  • Easy Service
    CAN J1939 diagnostic interface and Briggs & Stratton EFI tools simplify troubleshooting and allow seamless integration with OEM systems.
  • Fewer Air Filter Changes
    Cyclonic air filtration enables industry-leading 600-hour air filter intervals—cutting downtime and consumable costs.
  • Reduced Noise and Vibration
    Significantly reduced vibration and quieter operation improve user experience and long-term equipment stability.
  • More Efficient Power Management
    ETC and governed idle deliver responsive, load-aware power with enhanced fuel efficiency and consistent engine output.
  • Longer Oil Maintenance Intervals
    Doubled oil service intervals and up to 50% lower oil wastage reduce labor and operating costs while improving environmental performance.
  • Advanced Engine Protection
    Low oil sensor and computer-controlled ignition safeguard against overheating and damage, maintaining engine longevity.
  • Zero Overhang Muffler (Optional)
    Flush-mount muffler ensures clean engine outlines for simplified installation and repower solutions.
