FHI to add 2 models to the Robin EX Series general-purpose engines

Fuji Heavy Industries Ltd. (FHI), the maker of Subaru automobiles, will begin mass-producing and selling
the EX40 and EX35 as the top-of-the-range models of the general-purpose overhead camshaft (OHC)
engine Robin EX Series in February next year.

The Series has been received well as a power source forsmall construction machinery or power generators, compressors and small agricultural machinery.
The EX Series has sold approximately 1.7 million units both at home and abroad to date since it hit themarket in December 2001.

With four models ranging in displacement from 126 cc to 265 cc available,

the series has been rated highly by users because it has achieved both outstanding low-emission
environmental performance and user-friendliness, such as low noise and easy start-up operation, with thetraditionally reputed durability and reliability kept intact.
The EX40 and EX 35, which will be added to the Series this time, will shore up the lineup to enhance theSeries’ signature environmental- and user- friendliness and excellent mountability even further, whileachieving the top-of-the-class output as well.
FHI operates the general-purpose engine business in its Industrial Machinery Company.
won high-level reliability of users from all over the world.

Its engines haveThanks to its rich lineup, they are used as

power sources for a wide variety of applications from small construction and agricultural machinery, whichbuilds social infrastructure, to recreational equipment for people’s affluent lives.

With these newadditions, the company aims to become a global general engine manufacturer who can flexibly andpromptly respond to the diverse needs of customers through enhanced product lineup.

1. High output
Thanks to the adoption of a cam profile exclusively for intake and exhaust and the optimization of theshape of the intake/exhaust port and the shape of the combustion chamber, the top-of-the-class-level
maximum output of 10.3 kW/14.0 ps (the EX40 gross output) is achieved.
2. Environmental considerations
The EX40 and EX35 meet the Tier 3 emission standards by the California Air Resources Board (CARB)
and the Environmental Protection Agency (EPA) by employing the dorm-shaped combustion chamber
thanks to the OHC valve narrow-angle layout, without using a special catalyst.
Moreover, the adoption of the OHC mechanism and the correction of cooling balance achieved theminimization of the cylinder deformation, which results in less oil consumption as well as higher
combustion efficiency, thereby improving fuel economy.
3. User friendliness
User friendliness is embodied in various aspects: 1) a newly developed resinous air cleaner has lowered thenoise level by 2 dB* from the conventional model; 2) optimized combustion chamber design has improved
ignition characteristics; 3) optimized decompression timing has achieved the top-of-the-class light recoil
operation and surefire startability.

4. Superb mountability
The adoption of an inclined cylinder has achieved a lightweight and compact design. Vibrations havebeen reduced by cutting down on the weight of parts and improving rotation balance to increase
mountability on operating machinery. In addition, compatibility is ensured by keeping the same engine
mount and center height as the current models.
