B&S Vanguard 37HP EFI KEYWAY Shaft Engine WITH CYCLONIC AIR FILTER

VANGUARD EFI
Optimizes fuel injection and spark timing so the EFI engine delivers significant fuel savings, greater efficiency, easier starting and higher productivity.
HOW IT WORKS
Vanguard EFI technology utilizes the Engine Control
Module (ECM) to tune every single operating point unique
to the engine. It takes in all of the signals from the
engine sensors to make cycle-by-cycle decisions on how
much fuel and spark to provide the engine and when.
