Product InfoThe Aquamist HFS3 Water Injection System
Since the introduction of Water Injection Systems with fuel flow tracking by Aquamist in 2003, this method has truly earned its position in the performance industry as the most effective method to meter water/methanol flow for delivering predictable and consistent power.
In order to keep up to date with the fast pace of direct injection (Di) systems, we have refined the engine load detection circuitry to extract and process more engine load information. The newly revised algorithm of the HFS-4 reads fuel-IDC, high pressure fuel-line pressure and manifold pressure (boost).
A ‚ÄúFast Acting Valve‚Äù (FAV) controls the delivery rate based on a PWM signal from the controller. The FAV enables superior linearity and atomization across the entire injection range compared to other systems. A constant line pressure (160 psi) to the FAV is provided by an Aquatec pump working in the ‚Äúby-pass‚Äù mode. This method most closely follows the typical automotive fuel injection system for unmatched precision and driveability characteristics. Currently, aquamist is the only company uses a PWM-valve delivery method. Not to be confused with a progressive pump speed (PPS) system with a slow on/off valve to stop dribble.
The combination of a superior method of delivery and a precision direct -injection signal decoding algorithm, the HFS-4 is the most advanced and capable injection system in the world today. In addition, the HFS-4 is also backward compatible with all conventional fuel injection systems.
