Performance Curves

The SAE J1349 standard measures net horsepower with the manufacturer’s production muffler and air cleaner in place. Net horsepower more closely correlates with the power the operator will experience when using a Honda engine powered product. 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 operation speed of the engine in application, environmental conditions, maintenance and other variables.

TROUBLESHOOTING TIPS

STORAGE & TRANSPORT TIPS

SHOP MANUALS

Auto Choke System

×

Honda’s Auto Choke System This user-friendly system is truly automatic, eliminating any manual manipulation of levers.

The engine starts easily whether cold or hot and is ready to use immediately. Once the engine is up and running, the Auto Choke automatically returns to an optimal operating position.

Automatic Mechanical Decompression System

×

All engines

Honda’s automatic mechanical decompression system is designed to give you quicker, easier starts.

This system, which is connected to the camshaft, reduces compression by opening the exhaust valve slightly when the engine is being started. This reduces the amount of force needed to start the engine and improves starting performance.

The system disengages automatically after the engine starts to prevent any power loss during normal operation.

Belt-driven OHC design

×

Mini 4-Stroke Series

In addition to the milder operating noise of 4-Stroke engines in general, the Mini 4-Stroke’s belt-driven OHC design further reduces unpleasant mechanical noise. Its lighter piston and other moving parts help keep vibration to a comfortable level.

Controller Area Network

×

SAE J1939 CAN Bus (Controller Area Network) communication functionality provides ECU (Electronic Control Unit) connectivity with less wiring. It enables a variety of complicated electronic controls to be linked to improve operability.

Cycloflow™

×

Honda Cycloflow™ technology enhances the air-fuel mixture and makes it easier to start the engine and idle smoothly while making it more resilient to poor quality fuel.

New V-shaped valves and a pent-roof combustion chamber enable air in cylinder to flow more smoothly and maximizes the mixing of fuel. The longer stroke design also enhances turbulence in the cylinder, helping the mixture of air and fuel.

Drive By Wire

×

Drive-By-Wire unlike conventional models, has no throttle cable. An ECU controls a throttle motor via an electrical signal. Ideal throttle control is possible, from conventional type user-operated throttle control, to a variety of automatic control by the ECU.

Electronic Fuel Injection

×

Electronic Fuel Injection (EFI), which detects the state of the engine using sensors supplies the optimum amount of fuel to the engine according to its working conditions. EFI Improves fuel economy, reduces exhaust gas, and achieves excellent usability and easy maintenance.

Electronic Fuel Injection Starting

×

Electronic Fuel Injection eliminates the need for a manual choke, making starting simple. In addition, starting is improved as the fuel is sealed within the injector and fuel hose reducing fuel deterioration, and making smooth engine startup possible even after long-term storage.

Electronic Governor

×

iGX Series

The electronic governor minimizes governor droop. This increases available power.

For most normal engines, available power is decreased when the engine is approaching wide open throttle.

The iGX’s advanced electronic governor eliminates this by electronically controlling the throttle to achieve a higher effective power output.

Engine diagnosis

×

Engine diagnosis utilizes Dr. H. software, linked via USB to tablet or PC for quick repairs.

Fuel Off

×

The new integrated Fuel-Off position on the engine control allows the user to stop the flow of fuel to the engine when pressure washing is complete.

How does it work - With the engine running and the switch placed in the Fuel-Off position, the fuel flow to the carburetor is stopped. The engine will continue to run until the majority of fuel remaining in the carburetor is consumed and the engine shuts down.

Using the Fuel Off feature when shutting your pressure washer down helps prevent sticky carburetor buildup which makes for cleaner storage and easier future starting.

Full 360 "any-side-up" operation

×

Mini 4-Stroke Series

The innovative design of Honda’s Mini 4-Stroke engines allows them to be used and stored in any position for full 360° usability. Upright, sideways, even upside down – the Mini 4-Strokes will still run great.

An exclusive Honda rotary-slinger lubrication system keeps oil in a completely misted state and circulates it using pressure fluctuations generated by the movement of the piston.

Built-in passages effectively return the circulated oil to the oil reservoir from every part of the engine. An oil return port positioned in the center of the reservoir prevents oil from accidentally flowing into the combustion chamber.

Approximately half the operating cost of comparable 2-stroke engines

×

Mini 4-Stroke Series

Efficient 4-Stroke technology not only offers superior fuel economy, it also requires no mixing of oil in the engine’s fuel supply. This substantially reduces both oil consumption and the emission of unburned oil in the exhaust.

The results include better all-around environmental performance and operating costs that actually decrease the more the engine is used!

Hemispherical Combustion Chamber

×

V-twin Series

Honda’s hemispherical combustion chamber was inspired by our proven racing technology. It offers the highest V-Twin compression ratio on the market.

The power is transmitted through forged-steel connecting rods and a forged-steel crankshaft, supported by a full-pressure lubrication system.

• 9.3:1 compression ratio generates tremendous power.
• Excellent combustion efficiency.
• Allows a radial configuration to create high volumetric efficiency.
• Places the spark plug near the center of the chamber for optimal flame travel.

This means increased engine efficiency and more power to your application.

High Capacity Oil Pump

×

V-Twin Series

The lubrication system uses a high capacity pump with discrete chambers. This facilitates consistent oil delivery.

The high output oil pump offers numerous benefits:

• Twice the capacity of the previous model
• Redesigned pump cover and sealing system ensure engine reliability
• Full pressure lubrication to the flywheel, PTO, and connecting-rod bearings

The result?

• Reduced friction
• Extended engine life
• Less mechanical engine noise

Integrated Cylinder and Head

×

V-twin Series

The idea of integrating the cylinder & head into one unit is radical. Radically smart. It eliminates the head gasket, head bolts, and allows for more airflow and better cooling.

Speaking of cooling, improved cooling means better combustion management. Cooling is also improved by each of the lightweight aluminum pushrods being housed in a separate tube to achieve enhanced airflow.

When you put it all together (with fewer parts) you get an engine with reduced emissions and greater-than-ever durability.

Integrated ECU (electronic control unit) with a self-tuning regulator (STR) governor

×
