Available as an option on GCV and GSV models
Honda’s Auto Choke System is available for use on GCV160 and GCV190 engines in fixed-throttle lawnmower applications. This user-friendly system is truly automatic, eliminating levers and cables.
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.
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.
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.
GC series, GS series
A truly innovative combination of a compact combustion chamber, overhead cam configuration and uniblock construction significantly reduces fuel and oil consumption as compared to conventional side-valve engines.
Honda’s simple design has made the GC and GS Series lighter and more compact than any engine in their class. Plus, simple construction has minimized the number of parts, making the engine more reliable and easier to operate.
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.
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.
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!
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.
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
