Honda takes intelligence
to a whole new level.
H
onda’s innovative iGX Series
engines are a new generation
of intelligent computer-controlled
general purpose engines. Honda
iGX engines feature an integrated
ECU (electronic control unit)
with a self-tuning regulator (STR)
governor system that allows the
engine to communicate with the
machine it is powering to achieve
optimal performance. The ECU
enables drive-by-wire remote
control operation of the engine,
regulating functions such as
starting, throttle, ignition timing
and diagnostics. Therefore,
engine speed can be programmed
and varied based on the
equipment application’s load
and speed requirement.
W
ith their multi-function
design, iGX engines are
the ultimate choice for complex
commercial and residential power
equipment applications.

*
You always
knew they were worry free, but now we’ve put it in writing.
* The power rating of the engines indicated in this document measures the net power output at 3600 rpm (7000 rpm for model GXH50, GXV50, GX25 and GX35) and net torque at 2500 rpm, as tested on a
production engine. Mass production engines may vary from this value. Actual power output for the engine installed in the final machine will vary depending on numerous factors, including the operating speed
of the engine in application, environmental conditions, maintenance and other variables.
