Honda GX35 Four-Stroke Handheld Engine

The GX35 mini four-stroke engine is Honda™s most powerful engine for handheld applications.  The 35.8cc GX35 which incorporates Honda™s 360-degree-inclinable any side up, mini four-stroke technology, is the lightest and most compact engine of its kind.  This powerful engine effectively bridges the weight gap with the two-stroke competition while delivering all the advantages of a four-stroke engine.

The innovative design of the GX35 allows it to be used and stored in any position.  The engine™s 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, ensuring that oil cannot accidentally flow into the combustion chamber.

The GX35 delivers powerful output across a wide range of operating speeds with ample low-speed torque, which means that it does not always need to be operated at wide open throttle.  This reduces noise and operator fatigue, while substantially increasing fuel economy and decreasing emissions.  The accelerator pump-equipped carburetor, combined with a lightweight flywheel, results in quick throttle response and rapid acceleration, while the use of mechanical decompression results in a substantial decrease in start rope pull weight. 

Efficient four-stroke technology not only offers superior fuel economy, but it also requires no mixing of oil directly into the engine™s fuel supply, thus substantially reducing both oil consumption and the emission of unburned oil in the exhaust.  The results include better all-around environmental performance and operating costs.
