The HS 320 HO (high output) is our high performance water/hydrogen fuel injection system for large diesel trucks (or comparably sized stationary applications) that uses only distilled water as a liquid fuel source. A small percentage of methanol is added for frost protection in freezing temperatures. This system can see paybacks as fast as 12-18 months on high-mileage tractors, which means projects can be entirely cash flow positive with financing!

In addition to improving your fuel efficiency, emissions, and horse power, this system reduces down time, lowers operating costs, extends engine life, and allows you to safely maintain loaded speeds, ensuring on-time deliveries. Corporate fleets can experience astounding returns on investment.

The HS 320 HO is a fully adjustable system, allowing the unit to be used on almost all heavy duty diesel engine applications. Typical water consumption is 0.75-1.0 gallons per hr. Heavily loaded trucks may use up to 1.5 gallons per hour in applications such as rock hauling. Lightly loaded trucks with lower EGTs use less water per hr. There's a simple variable control on each unit to easily adjust and optimize flow rates in the field if desired. For even larger changes, the injector tip can also be easily changed in the field.

  • Eliminates or greatly reduces black soot under normal driving conditions.
  • Largely eliminates the EGR downtime issues, the exhaust is cooler and much cleaner.
  • More horsepower and a higher torque range throughout the power band at normal driving style.
  • Now able to use all of your horsepower without high EGTs in most performance or race tuned trucks.
  • Quicker turbo spool up.
  • Easy to Install. Installations take 3-4 hours.
  • Removes harmful carbon deposits.
  • Longer time between oil changes.
  • Lowers oil temps by an average of 25 degrees.
  • Low power draw (under 8 amps) works with stock power supply.
  • Will not set a CEL or trouble code if installed as directed.

Additional Details

For fleet owners, we recommend starting with a small pilot order of 1 or more units and using data loggers to record before and after measurements. This will give your financial models increased accuracy and it enables feedback from your drivers as well. We offer a money-back guarantee on every unit sold to make it easy, inexpensive, and low-risk for you to see real numbers on Your trucks with Your drivers.

This system is mechanic-install friendly with the HS 32 Install Kit. This kit typically includes a drill bit and tap for the hot and cold side ports, high temp hoses, hose clamps, 25 ft. of pump power wire, 25 ft. of 1/8 OD water charge line, main power wire and terminals for power to the system. Installations take up to 4 hours and may require a second person at times for larger trucks.

In addition to the installation kit, we can provide video directions and edited photo directions of your engine if you email us photos, and we also offer verification of correct installation practices of photos that are emailed to us post-installation. If you have any questions that are not covered in the instruction manual, we are just a phone call away.

Customer Feedback

International 9900 2007 Model Tandem Drive Axles Heavy Diesel Configure I am very satisfied with the performance of our Aquatune International system, on our 2007 International 9900 semi-tractor with a Cummins ISX engine rated at 475 HP. We haul rock for a stone quarry with B Trains grossing 139,500 pounds. With this system we can increase our mileage overall by 17.4% (when driving aggressively) to as high as 34.4% if we drive normally and similarly to the previous trips pre-Aquatune. Horsepower and Torque is up and black smoke and high EGTs are greatly reduced, allowing us to better maintain the speed limit on hills even while loaded, with considerable less gear shifting required. What is not to like about this, it pays for itself quickly and is certainly more productive time-wise because of being able to maintain our loaded speed on hills. Joe W Milverton ON
