The HES Technology replaces a traditional carburetor or fuel injection system. It costs less to manufacture than a carburetor or fuel injection system as it has less components and does not require a computerized control to function, as does a fuel injector. Additionally, costs are further reduced as the system negates the need for any additional pollution control devices that are currently required under the Clean Air Act for engines running on fossil fuels.

It is important to note that a carburetor or fuel injector has to be sized to the engine it is placed on. For example, a carburetor for a 6.5 HP engine cannot fit an 8.5 HP engine. The same applies to a fuel injector. The costs increase as the HP application increases. With the HES Mixing Block™, applications are transitional and interchangeable up to at least 13 HP.

Here is a table comparing the HES Mixing Block™, a carburetor, and fuel injector for a small engine.

OUR MIXING BLOCK™ REQUIRES LESS TIME TO ASSEMBLE
THAN A CARBURETOR OR FUEL INJECTOR SYSTEM

Device	Number of Parts
Carburetor for a 6.5 HP Engine	60 3 parts are casted 5 parts are plastic injection molded 2 parts are stamped
Fuel Injector for a 7.5 HP Engine	133 1 part is casted 11 parts are plastic injection molded 2 parts are machined and stamped 1 part is rubber injection molded 1 part is a computer board
HES Mixing Block™	20 2 parts are O-rings 4 parts are casted

(NOTE: We do not delineate engine size, as the Mixing Block™ is transitional from small to large HP.)

*HES has successfully completed testing of the Mixing Block™ up to a 13 HP engine with complete transitional capabilities. HES believes the Mixing Block™ will transition up to a 30 HP engine before the block has to be re-sized.
