Product Description
The natural gas powered Oxx Power brand of utility
ready generators is designed for quiet, ultra low
emissions. The resulting generator set achieves an
industry-first implementation for continuous duty power
applications.
Engine
A specially modified Oxx Power 572 cubic inch dry fuel
engine powers the generator set. The engine has
reduced friction, increased robustness and specially
modified fuel delivery, inter-cooled turbocharger and
controls. These controls coupled with the mechanical
advances enable reliable operation at higher
synchronous speeds of 3,600 RPM.
Emissions
Natural gas engines have fewer emissions than those
powered by diesel and gasoline. Studies have indicated
that emissions have been reduced by as much as 1/2
that of other hydrocarbon fuels.
Fuel Delivery
The fuel delivery system is electronically controlled
sequential port injection. Exact fuel delivery using closed
loop control methods guarantees proper fuel mixture is
maintained.
Cooling System
The standard cooling system provides reliable operation

The engine is coupled to a class H, 2 pole, brushless,
self-regulating alternator with winding pitch designed to
reduce the harmonic content of the output waveform.
The electrical output has 12 leads providing voltage and
phase flexibility. The regulator maintains 1% voltage
regulation and includes under speed and overload
protection. Construction is compliant to European
Communities (CE), Canadian (CSA) directives and
recognition under UL1446 as part of UL
Control Panel
An industry standard digital auto-start controller with LCD
display offers user and service friendly operation. Critical
operational information is continuously updated. The
panel includes typical NFPA 110 type controls and
displays. Manual and automatic operating modes are
standard. Operation with an automatic transfer switch is
supported in the auto mode with a switch closure input
for remote start.
Noise and Vibration
The standard sound attenuated package has robust skid
base supports that have integral vibration isolators for
the engine, radiator, and generator minimizing vibration
transmission, enclosure panels, ducted air inlet and
outlet features, and sound absorption materials all
included. A super-sound attenuation option is available.

Engine
The generator set is power by HEC Oxx Power 9.4 L (572 CID), spark ignited, turbocharged, natural gas fueled V-8,
roller Cam engine. A rugged cast iron cylinder block with D ported Cylinder Heads with Long Reach Mounting Bolts into
Main Bearing Bulkhead is used to maintain resistance to heat distortion and provide durability. Cast aluminum intake
manifold fitted with hydrogen fuel injectors and accompanying fuel rails provide improved power and efficiency. An
Even Firing Order and Internal Balance Shaft enable nearly vibration-free operation. Four bolt mains and priority oiling,
industrial intake and exhaust valve insert have been upgraded increasing durability and maintenance intervals. The engine also has 35% better cooling in the block and also in the heads. The designs of both were done to improve longevity
of the engine. The D ported heads are tuned for 3400 rpm peak torque and fit perfectly with HECs desire to use 2 pole
generators. The intake manifold has been to accept fuel injectors and the larger air flow that comes with large displacement and low equivalence ratios (eqr). These engines are designed to operate with eqrs of .4 and below. This is very
lean and requires very good engine management.
The engine is supplied with an Electronic Engine Management System controlling key engine functions:

Generator
The alternator is a brushless, self-regulating design incorporating a rotating inductor with damper cage winding and a
fixed stator with skewed slots. The stator windings have a shortened pitch to reduce the harmonic content of the output
waveform. The alternators are made in compliance with the 98/37, 73/23, 89/336 CEE directives and their amendments,
and the CEI 2-3, EN60034-1, IEC 34-1, VDE 0530, BS4999-5000, CAN/CSA-C22.2 N°14-95 - N°100-95 regulations, UL
1446 and UL2200. Tests to verify the electromagnetic compatibility have been carried out as required by the standards.
The robust mechanical construction gives good access to the generator output connections, and allows the user to inspect the various components with ease. The casing is made of steel, the shields of cast iron, and the shaft of with an
integral keyed cooling fan. The mechanical protection level meets standard IP21. Insulation materials meet Class H
requirements, and all rotating components are epoxy resins impregnated; higher voltage parts, such as the stators, are
vacuum treated. Radio interference suppression meets the requirements of grade “N” of VDE 0875 regulations. Filters
designed for more stringent regulations, (such as VDE 0875, grade “K”, MIL 461E) are available upon special request.

Control System
A digital control panel to initiate manual and automatic starting and stopping controls is provided as standard. The
panel includes basic display and fault indications with front panel programmable configuring. The generator set controller provides three operational modes: Run, Off and Automatic. The modes are front panel switch selectable positions.
Mode Position Descriptions:
(1)
(2)
(3)
Run: Manually initiates engine start and run
Off: Stops the engine and resets the machine shutdown and lockout faults
Automatic: Engine is started by closing a remote start contact and stopped when it is opened
The Automatic switch position enables the engine to start automatically when the normal electric power fails or falls below specific limits and to stop the engine automatically after the normal power supply resumes. The signal for starting
or stopping the engine is sensed through a switch closure in an auxiliary contact located in the automatic transfer
switch.

HISTORY
Hydrogen Engine Center's beginning was in 2003. The company was created with the objective of producing stationary,
distributive, power, for industrial clients. The idea was to provide “added value” by specializing in "alternative fuels",
such as hydrogen, natural gas, anhydrous ammonia, methanol, propane, and syn-gas.
Even though HEC utilized most of its resources in developing new technology, nearly 1500 engines and gensets have
been successfully sent to the field. HEC has made significant technological advancements in its first 10 years of existence. Among them, we have patented a special alignment hub which allows our gensets to run at 3600 rpm, twice as
fast as our competitors, producing twice as much power. This gives us what we call an “unfair advantage”, since it gives
us a special price advantage.
HEC has designed and built two special engines patterned after the Ford 300 and the Ford 460 engines. Over 30 modifications, including specialized electronic controls and a proprietary fuel injection system have been made, to make these
engines truly unique. HEC has developed the largest internal combustion, spark-ignited, hydrogen engine, creating over
200 kW of power, with one genset. This has only been made possible by the invention of a special HEC intake manifold.
To be recognized in the “distributive power sector” reaching a one megawatt milestone is an important achievement.
HEC has reached this pinnacle of success with its N+1 technology, allowing multiple gensets to be installed in parallel,
creating multiple megawatts of power. The company was the first to ever run an internal combustion, spark-ignited, engine on anhydrous ammonia; which we believe will play an important role in the future of hydrogen. The uniqueness and
significance of what we are doing has been recognized by the patent office. An important patent involving the use of
anhydrous ammonia and hydrogen in an internal combustion engine was granted to the company in the fall of 2011. This
was "a first" since no other governmental agency even recognizes anhydrous ammonia as a fuel. The future of HEC will
be in the exploitation of its technology by manufacturing and marketing gensets. While continuing to play a leadership
role in developing power with the use of hydrogen and other alternative fuels, we feel it is important to respond to market
forces. Natural gas being a much cleaner fuel than diesel, reducing pollution by up to ½, is an area that we will be targeting more aggressively in the future.
