Economy Controlled Motor

Along with Honda’s Programmed Fuel Injection (PGM-FI), most models in Honda’s outboard engine range incorporate lean burn control technology, which allows combustion to operate on a leaner air/fuel ratio than stoichiometric air/fuel. An O2 sensor precisely controls the air/fuel mixture for the best fuel economy at cruising speeds. The mode in which lean burn control is used during cruising to achieve higher fuel economy is referred to as ECOmo.

Lean burn control

Adjusts the air/fuel mix according to speed and load to maximise efficiency.

Inclusion of lean burn control offers significantly improved fuel consumption over direct injection two-stroke models as well as over competing four-stroke models.

The mode in which lean burn control is used is referred to as ECOmo (Economy Controlled Motor).

Racing technology

VTEC™ ensures smooth, stable idling with an even further reduction in fuel consumption, while the increased valve lift at high revs broadens the torque curve and provides incredible top-end power.

Variable Valve Timing and Lift Electronic Control (VTEC TM) delivers more power, torque and efficiency at every speed.

At 5200rpm, a high-lift cam engages to pack more air into the combustion chamber to produce more power.

VTEC™ works to produce a longer, flatter torque profile: the ultimate in fine-tuned performance. (VTEC is available on BF100, BF150, BF225 & BF250 models)
