EFI and ETC Engines | Vanguard® Commercial Power

A Big Win For Your Bottom Line - Electronic Fuel Injection (EFI) and Electronic Throttle Control (ETC)

WE DO IT BETTER. OR WE DON'T DO IT.

Smart engineering proven by grueling real-world testing optimizes engine performance and makes Vanguard EFI engine technology the one built to last.

How it works: The Engine Control Module (ECM) constantly monitors and fine-tunes every single engine operating point thousands of times per minute. 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 EFI engine and when to do it.

Vanguard’s Electronic Fuel Injection system delivers:

Improved starting at all temperatures.
Smooth performance at all elevations.
Quick load acceptance for optimized performance at faster speeds.
Reduced fuel consumption, as fuel is delivered more efficiently.

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.
