iGX Intelligent General Purpose Engine

Honda™s iGX 440 overhead cam (OHC) general purpose engine sets a new standard for ease of use, value fuel efficiency, and quiet operation. The iGX features an integrated electronic control unit (ECU) that delivers complete drive-by-wire remote control capability and controls key aspects of engine operation.  The integrated electronic control unit communicates with the application to achieve optimal performance.  It is ideally suited for a wide range of commercial and residential power equipment applications which include, pressure washers that automatically start of stop when the user squeezes or releases the trigger handle; water pumps that can be automatically activated based on water level by remote switch, lawn mowers that can automatically vary engine speed based on load; and generators that can automatically start when required and vary engine speed based on electrical draw.


The iGX engine was designed around four key platforms:  intelligence, ease of use, lower fuel consumption, and noise reduction: 


·         Intelligence:  the computer-controlled design allows communication with its application, enhancing automation of the task.

·         Ease of use: the engine™s design eliminates the need for manual manipulation of the choke and throttle. The self-diagnosis function of the iGX also improves ease of operation and maintenance.

·         Noise reduction: superior over that of conventional engines; the iGX offers a noise reduction of approximately 4 db.

·         Lower fuel consumption: the technology results in lower fuel consumption and lower emissions, through reduced total engine running time and engine speed that can be lowered based on power demands.
