Taking intelligence to a whole new level. The iGX270 and iGX390 are technologically advanced, offering you features and performance like no other small engine in the world. With its multi-function, high-performance design combined with the same superior reliability of Honda's legendary GX engines, the iGX sets a new standard for engines. COMMON APPLICATIONS Pressure washers Generators Forestry equipment Construction / industrial equipment Agricultural equipment Water pumps Small Engines ADVANCED TECHNOLOGY Integrated ECU (electronic control unit) with a self-tuning regulator (STR) governor system. Engine senses and adjusts RPMs to match the application's load and speed requirements. ECU enables drive-by-wire remote control operation of the engine and regulates functions such as throttle position. FUEL EFFICIENT OPERATION Fuel economy is increased by approximately 15% over a similar conventional engine Auto Throttle HIGH POWER OUTPUT Electronic governor minimizes governor droop, increasing available power Allows the engine to respond significantly faster to the load SMOOTH PERFORMANCE ECU fine tunes the throttle position to maintain a precise engine speed. Precision engineered components result in lower vibration EXCEPTIONALLY QUIET Enhanced muffler design reduces overall engine noise Large capacity, multi-chamber exhaust system Reduced mechanical noise due to higher compression and piston design Forged steel crankshaft and rigid crankcase PROVEN RELIABILITY Long-life air filter Multi-function Oil Alert EASY TO USE AND MAINTAIN No manual manipulation of the choke or throttle - Easier for inexperienced users to operate Wide fuel filler opening with ratchet-type fuel cap Easy maintenance - ideal for rental applications Easy access connectors for flexible connection of remote control and for ECU programming Externally serviceable Oil Alert EASY STARTING Auto Choke Low effort recoil starter with automatic decompression Camshaft profile is optimized for easy starting Large diameter recoil starter assembly Automotive-style ignition coil on spark plug Digital CDI with higher spark plug voltage EMISSIONS COMPLIANT No catalyst necessary AVAILABLE OPTIONS Spark arrester available Charge and lamp coils with multiple output options available SPECIFICATIONS Engine Type: Air-cooled 4-stroke OHV Bore x Stroke: 88 X 64 mm Displacement: 389 cm3 Net Power Output*: 11.7 HP (8.7 kW) @ 3,600 rpm Net Torque: 19.5 lb-ft (26.4 Nm) @ 2,500 rpm PTO Shaft Rotation: Counterclockwise (from PTO shaft side) Compression Ratio: 8.2:1 Lamp/Charge coil options: 3A, 20A Carburetor: Horizontal type butterfly valve Ignition System: Digital CDI with variable ignition timing Starting System: Recoil/electric Lubrication System: Splash Governor System: Electric STR (Self Tuning) Air Cleaner: Dual element Oil Capacity: 1.16 US qt (1.1 L) Fuel Tank Capacity: 6.4 US qts (6.1 liters) Fuel: Unleaded 86 octane or higher Dry Weight: 82 lb (37 kg) DIMENSIONS Length (min): 16.0" (407mm) Width (min): 19.1" (485 mm) Height (min): 17.7" (449 mm) PTO E type: Tapered shaft H type: Reduction type PTO L type: Reduction type PTO P type: Threaded type (SAE) Q type: Straight shaft R type: Reduction type PTO V type: Tapered shaft
