Honda Engine Technology

Honda engines offer a variety of advanced features for performance, durability, and the highest quality available. Click on any features to learn more.

Automatic mechanical de-compression system
Automatic mechanical de-compression system

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.

Variable Timing Digital CDI ignition
Variable Timing Digital CDI ignition

Honda’s Variable Timing Digital CDI ignition allows optimal ignition timing based on engine speed. The result:

• Excellent starting,
• High power output,
• Reduced fuel consumption, and
• Outstanding emissions performance

An engine rev limiter is also incorporated to prevent over-revving.

Oil Alert
Oil Alert

Honda’s Oil Alert system helps to prevent engine seizure due to a low oil condition. The system consists of an oil level sensor inside the crankcase. When the oil reaches a level that is too low for safe operation, the engine warns you or stops automatically

Improved reliability GX, V-twin
Hemispherical combustion chamber
Hemispherical combustion chamber

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.

Fuel efficiency and higher output V-twin
Integrated cylinder and head
Integrated cylinder and head

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.

Improved reliability and combustion V-twin
High-capacity oil pump
High-capacity oil pump

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

Improved reliability V-twin
Compact combustion chamber, overhead cam design, and uniblock construction
Compact combustion chamber, overhead cam design, and uniblock construction

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 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.

Increased reliability, easier maintenance, and lighter weight GC
Lifetime timing belt design
Lifetime timing belt design

Honda’s GC engines use the world’s first small engine internal timing belt, designed to last the lifetime of the engine.

Small engine timing belts are usually external and are subject to wear caused by dirt. Honda’s internal timing belt runs in oil, eliminating the need for conventional drive gears.

This design:

• Improves lubrication,
• Reduces the weight of the engine, and
• Provides quieter operation.

Improved reliability GC
Auto Choke System
Auto Choke System

Available as an option on GCV 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.

Easy starting Optional for GCV
Full 360° "any-side-up" operation
Full 360° "any-side-up" operation

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 centre of the reservoir prevents oil from accidentally flowing into the combustion chamber.

Ease of use Mini-4-Stroke (GX25, GX35)
Approximately half the operating
cost of comparable 2-stroke engines
Approximately half the operating
cost of comparable 2-stroke engines

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!

Reduced cost of ownership Mini-4-Stroke
Belt-driven OHC design
Belt-driven OHC design

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.

Renowned reliability and quality.

Honda sets the standard for reliable, hard-working engines. Our engines are built with high-quality components designed for optimum performance in the harshest environments. But don't just take our word for it. Honda stands behind our engines a three-year commercial warranty on all GX engines, 100cc and larger.

Or ask a Honda engine owner. Next time you visit a rental centre, see a landscape truck, or pass by a construction site, you'll probably see a Honda GX engine-powered piece of equipment. Stop and ask them what they think of the Honda engine. Chances are they'll tell you they wouldn't use anything else.
