Briggs & Stratton introduces the gasoline-powered electronic fuel injection (EFI) model engine, which is an extension of the company’s Vanguard 3/LC three-cylinder, liquid-cooled commercial engine line. The EFI system automatically adjusts engine settings in real time for quick, no-choke cold starts, and to compensate for altitude and environmental variables. The engine is rated at 34 gross hp and an advanced 32-bit engine control unit provides responsive performance with enhanced driveability, the maker says. On-board diagnostics built into the unit are designed to provide accurate troubleshooting for reduced equipment downtime.
