ELECTRONIC FUEL INJECTION (EFI) & ELECTRONIC THROTTLE CONTROL (ETC)
Reduced Fuel Consumption. Improved Stale Fuel Resistance.
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. This in turn means improved starting at all temperatures, smooth performance at all elevations, quick load acceptance and reduced fuel consumption.
Vanguard ETC technology reacts instantaneously to any applied load from its environment to maintain smooth, consistent power in any condition.
Here’s how it works: The flywheel speed sensor detects any change in RPM and sends a signal to the throttle body, ensuring consistent engine speed.
Vanguard’s Electronic Throttle Control system delivers:
- Smooth, consistent power no matter the terrain or load on the engine.
This is Productivity Defined.
